HH45137 e3fac5e9fa [Fix]: Add Task/Mesh shader enum mapping 
Map the Task and Mesh shader stages to their NV OpenGL enum values in ProgramEnumConverter so shader stage conversion handles task and mesh pipelines correctly.

HH45137 3823fe528c [Feat, Test]: Add NV mesh shader support 
Advertise GL_NV_mesh_shader in the DirectVulkan backend and expose the new task/mesh shader stages in the GL-to-MG and glslang conversion layers. This also wires the mesh task drawing entry points and adds a focused MeshShader test covering extension discovery and task shader compilation.

name: anland-mobilegl-plasma
description: Bring up, rebuild, deploy, switch backends on, test and debug the "MobileGL + anland + KDE Plasma" stack - a rooted Android tablet whose anland APK embeds the MobileGL server, plus a Droidspaces Arch Linux ARM container running KWin/plasmashell/Chrome through the MobileGL client library and GBM backend - driven from this Windows machine (Git Bash, WSL archlinux, adb). Use it after a phone reboot, when changing server (NDK) or client (container glibc) MobileGL code or anland's KWin backend/patch, when switching Espryt/Magma, when validating zero-copy dma-buf presentation, and when chasing crashes, black windows, noise or software-rendering fallbacks in the Plasma session.

# MobileGL on anland KDE Plasma
**Setting this up on a new machine or phone from source: `reproduce.md` next to this file.**
Human-readable runbook (Chinese, same content): `docs/Disaggregated/notes/anland/runbook-plasma.md`.
Background: `docs/Disaggregated/notes/anland/handoff-legacy-mobilegl-unified.md` (state, commits, known
issues) and `plan-ahb-dmabuf.md` (zero-copy design). All scripts are in `scripts/` next to this file;
parameters are documented at the top of each script and in `scripts/env.sh`.
**The phone may be shared with another session.** Before anything that restarts the app, the daemon,
the container session or replaces a library, run the read-only `scripts/device/status.sh` and make sure
nobody else is mid-test. Use your own `ct.sh` channel names (others use c, c2, c3, xd, xr, gbm).
## Architecture (10 lines)
1. Phone: Lenovo TB321FU (Y700, Adreno 750, Android 15, kernel 6.1), rooted with **KernelSU** (`/data/adb/ksu`, `ksud`; `su -c` works). USB serial `HA27Q3LQ`, or wireless adb `ip:port`.
2. anland APK `com.anland.consumer.mobilegl` (debuggable build of anland branch `legacy-mobilegl-unified`): UI process + private service process `:mobilegl` (`MobileGLWorker`), which loads the **server** `libMobileGL.so` (NDK, from MobileGL `feat/disaggregated`) and listens on abstract socket `@anland-mobilegl` from the first attached window on. One process serves every client (KWin, plasmashell, ksplash, Chrome...), one backend per process. `MobileGLWorker` is a **foreground service** (notification "Linux desktop is running" / action "Stop desktop"), so the server and the session outlive a hidden, locked or swiped-away window.
3. Backend = the app setting "Renderer backend" (Settings > Connection > MobileGL desktop; file `/data/data/<pkg>/files/mobilegl-backend`, default DirectGLES; also `am start ... --es mobilegl_backend X`). Espryt = DirectGLES, Magma = DirectVulkan. The server reads it when its process starts; the app publishes it as `/data/local/tmp/anland-mobilegl/backend` and the session copies that into the container's `/etc/mobilegl/backend` (what every client reports; mismatch = "Hello.backendType disagrees with pinned backend"). `debug.mobilegl.backend`, if someone sets it, still overrides the setting until the next reboot.
4. Experiment display daemon `/data/adb/modules/anland-daemon/display_daemon /data/local/tmp/anland-mobilegl/display.sock` (display/input broker), started by the app (below). The module only starts the original one on `/data/local/tmp/display_daemon.sock` at boot; leave that alone.
5. Container `arch-kde-mgl` (Droidspaces 6.4.5, Arch Linux ARM aarch64 glibc, host net, `rootfs.img` mounted at `/mnt/Droidspaces/arch-kde-mgl` on the Android side). Bind mounts: `/data/local/tmp/anland-mobilegl` -> `/run/anland-mobilegl`, `/data/local/tmp/display_daemon.sock` -> `/run/display.sock`.
6. `desktop-session.service` (User=swung0x48, **enabled**: the container boots straight into it, as the original image does) has drop-in `/etc/systemd/system/desktop-session.service.d/mobilegl.conf` (anland `producers/kde/Arch_v5/desktop-session-mobilegl.conf`, installed + enabled by `sync-build-kwin.sh`): `ExecStartPre=mobilegl-startup.sh wait` (until `@anland-mobilegl` listens in `/proc/net/unix` and the daemon socket exists), `ExecStartPre=+... sync-backend`, `Restart=always`, then `ExecStart=/opt/mobilegl/bin/mobilegl-startup.sh plasma`, which deletes the sticky software-renderer key, sets `MOBILEGL_IPC_PROBE_TIMEOUT_MS=0` session-wide (MobileGL never declines, so glvnd never falls through to another GL stack), writes a user drop-in for `plasma-kwin_wayland.service` (kwin_wayland_wrapper -> `/opt/mobilegl/kwin/bin/kwin_wayland` + `/opt/mobilegl/kwin/lib/libkwin.so.6.7.4`, `ANLAND_MOBILEGL=1`, `MOBILEGL_IPC_SURFACE=server`) and runs `startplasma-wayland`.
7. KWin 6.7.4 with anland's `anland` backend renders straight into the anland Android Surface through the server. While the window is not on screen (consumer disconnected) the backend powers its output down (DPMS Off + RenderLoop inhibited: no compositing, no frame callbacks) and back up when the window returns. Every other GL process is `MOBILEGL_IPC_SURFACE=offscreen` and presents through KWin.
8. Client = `/opt/mobilegl/lib/libMobileGL.so` (glibc aarch64), the container's **system-wide** GL vendor (section below): glvnd EGL vendor `/usr/share/glvnd/egl_vendor.d/10_mobilegl.json` (sorts before the distribution's `50_*.json`, which serves whenever MobileGL declines), GLX vendor `/usr/lib/libGLX_mobilegl.so.0`, settings from `/etc/mobilegl/client.conf` (`MOBILEGL_TRANSPORT=spawn MOBILEGL_IPC_DATA=shm MOBILEGL_IPC_CONTROL=unix:@anland-mobilegl`) + `/etc/mobilegl/backend`. No per-process environment is needed.
9. Zero-copy windows: client `wl_egl_window` frames are server-allocated AHardwareBuffer "shared images" exported as dma-buf fds over `zwp_linux_dmabuf_v1`; KWin imports them with EGL and the server recognises its own buffer by inode. KWin gets a DRM device via `GBM_BACKEND=mobilegl` -> `/usr/lib/gbm/mobilegl_gbm.so` (node is only an identity, never ioctl'd). Without linux-dmabuf the client falls back to wl_shm readback.
10. X11 (`docs/Disaggregated/notes/anland/plan-x11-gpu.md`): Xwayland draws with **glamor on MobileGL** (an offscreen session; `GBM_BACKEND=mobilegl` on KWin's render node; window pixmaps are shared images handed to KWin as linux-dmabuf buffers; its `glFlush` publishes them through the server, `/tmp/mgl-xwayland.client.log`); `ANLAND_XWAYLAND_GLAMOR=0` in KWin's drop-in brings back the software `-shm` Xwayland. GLX windows present their frames as shared images through **DRI3 + Present** (log `presented through DRI3+Present shared images`), falling back to readback + MIT-SHM / `xcb_put_image` when the X server has no DRI3 (`MOBILEGL_GLX_PRESENT=readback` forces it per app). Chrome runs ANGLE-GLES over MobileGL EGL with the GPU in its own process (`mobilegl-startup.sh chrome`; `MOBILEGL_CHROME_GPU=in-process` opts out), presenting GBM dma-bufs over linux-dmabuf; after a device loss Chrome restarts that process and repaints.
## First-time prerequisites (Windows host)
- Git Bash, `adb` (SDK platform-tools), CMake >= 3.22 and Ninja on PATH (seen: CMake 3.27.6, Ninja 1.13.2), Python 3 + Pillow (only `rec.sh`).
- Android NDK **27.2.12479018** at `%LOCALAPPDATA%/Android/Sdk/ndk/27.2.12479018` (override `ANDROID_NDK`).
- WSL distro **archlinux** with clang, lld, llvm, cmake, ninja. **lld's major version must equal clang/llvm-libs'** (lld 23 on llvm 22 broke `ld.lld`; working set: all 22.1.6). Then export the sysroot once: `bash scripts/xsysroot/refresh-sysroot.sh` (-> `~/sysroots/arch-kde-mgl` + `~/sysroots/aarch64-arch.cmake`; re-run after container package upgrades, then `xbuild.sh --reconfigure`).
- MobileGL worktree (never build in the shared main checkout): `GIT_LFS_SKIP_SMUDGE=1 git worktree add ...`, `git submodule update --init --recursive`, and copy `3rdparty/glslang/External/spirv-tools` from the main checkout (the submodule leaves it empty).
- anland worktree on `legacy-mobilegl-unified` (KWin patch/backend, startup script, `mobilegl-tools/`).
- Phone side that already exists and is NOT recreated by this skill: the APK (build: anland `consumers/anland_v5/android_consumer/MOBILEGL.md`, gradle `:app:assemblePlainDebug` with `MOBILEGL_DIST`, `-PmobileglApplicationId=com.anland.consumer.mobilegl -PanlandDefaultSocket=/data/local/tmp/anland-mobilegl/display.sock`, from Git Bash with `MSYS_NO_PATHCONV=1`; signed with this machine's `~/.android/debug.keystore`, so `adb install -r` works; reinstalling with another key changes the UID and needs the KernelSU grant again - `mobilegl-tools/ksu_grant.c`), the anland KernelSU modules (`anland-daemon`, `anland-awl`), the container with KWin's configured build tree `/root/mobilegl-build/kwin-6.7.4/build` and pristine `/root/gbm-dev/kwin-a/src`.
- Install the helpers once (container must be running): `bash scripts/push-tools.sh` (device/*.sh -> `/data/local/tmp/anl`, `mgrun` -> container `/usr/local/bin`, `kwprep.sh` -> container `/root`).
Run host scripts from Git Bash as `bash scripts/<x>.sh`. Raw adb with device paths needs `MSYS_NO_PATHCONV=1` and the whole root command in one quoted string: `adb shell 'su -c "..."'`. A device script can also be run without pushing: `MSYS_NO_PATHCONV=1 adb shell 'su -c sh' < scripts/device/status.sh`.
## Starting, idling, stopping - no manual steps
Nothing starts at phone boot (container `run_at_boot=0`). **Opening the app** (launcher icon = `am start -n com.anland.consumer.mobilegl/com.anland.consumer.MainActivity`, no extras; the APK's default socket is the experiment's, `-PanlandDefaultSocket`) calls `MobileGLDesktop.ensureStarted()` - the single trigger - which starts the foreground service and runs the APK's `assets/mobilegl-desktop.sh up` as root (`su`): display daemon if absent (the script leaves the app's cgroup first, so it survives the app) -> backend published -> container started if stopped -> `systemctl start --no-block desktop-session`. The window waits for the daemon socket; the server listens once the Surface is attached; the session's `wait` step then lets Plasma start. A reopen with everything up only reattaches the window. Log: `/data/local/tmp/anland-mobilegl/desktop.log`, logcat `AnlandMobileGL` ("MobileGL desktop up done in N ms").
Hidden window, screen off, lock screen or swiped-away task: server and session stay (foreground service); KWin turns the workspace's DPMS off (logs "viewer gone: output powered down"; windows get xdg_toplevel `suspended`, no frame callbacks) and back on ("viewer back"). Client swaps are paced by frame callbacks (`MG_Impl/EGLImpl/FrameThrottle.h`): interval >= 1 waits like any Wayland EGL; interval 0 (Chrome) drops to ~1 fps once a callback goes unanswered for 200 ms.
Measured 2026-10-03 (Espryt, Chrome on webglsamples aquarium; % of one core, phone = all of Android): open-to-desktop cold 7.5-12.5 s (daemon 0.5, server 1.0, container 1.5, kwin ~5, plasmashell ~6-7), after a phone reboot 8.5 s, reopen of a running desktop 0.2 s; visible phone 249% / kwin 13 / chrome 99 / server 57 / GPU 22%, hidden 54 / 0 / 6 / 2 / 0%, locked 38 / 0 / 8 / 3 / 0%. Stop desktop 1.7 s. Wireless adb does not come back by itself after a reboot (re-enable it on the phone). **Stop desktop** (notification action, or `am startservice -n <pkg>/com.anland.consumer.MobileGLWorker -a com.anland.consumer.mobilegl.STOP`) runs `mobilegl-desktop.sh down` (session + container stopped, daemon stays), closes the windows, ends `:mobilegl`.
```sh
adb connect <ip>:<port> # only for wireless debugging
export MSYS_NO_PATHCONV=1
adb shell 'su -c "sh /data/local/tmp/anl/bringup.sh"' # after a reboot: wake, dismiss keyguard, open the app, print the timeline
bash scripts/desktop-verify.sh push cold reopen idle # timed cold start, swipe-away + reopen, CPU/GPU visible/hidden/locked
adb shell 'su -c "sh /data/local/tmp/anl/status.sh"'
```
`droidspaces` has no `status` command; `droidspaces show` lists running containers. `device/run-plasma.sh` is a developer restart (session + logind user, then the app), needed after a rebuild because KWin does not reconnect to a new server process. `device/desktop-reset.sh` takes everything down to the post-reboot state. The old manual sequence (setprop, start container, `restart-daemon.sh`, `run-plasma.sh`) is gone; `restart-daemon.sh` remains for daemon debugging only.
## Build and deploy loops
**Server (Android, NDK) -> APK lib**
```sh
bash scripts/build-android.sh # -> <worktree>/build-android/libMobileGL.so (RelWithDebInfo, unstripped)
bash scripts/cyc.sh s1 # clear sticky SW-renderer key, push, swap into APK, restart session, screenshot $ANL_DIR/s1.png, print fatals
```
`device/swap.sh` overwrites `/data/app/.../lib/arm64/libMobileGL.so` keeping owner/mode/SELinux context (original saved as `/data/local/tmp/anland-mobilegl/libMobileGL.so.orig`); no re-signing. To swap without the session restart: push to `/data/local/tmp/anland-mobilegl/libMobileGL.new.so`, `su -c "sh /data/local/tmp/anl/swap.sh"`, then `run-plasma.sh` anyway (KWin does not reconnect to a new server process).
**Client + GBM backend (container glibc) via WSL cross-build**
```sh
bash scripts/xbuild.sh [--reconfigure] # WSL ~/mgl-xbuild-a64; ~150 s full, seconds incremental
bash scripts/xdeploy.sh # rename-into-place install of libMobileGL.so + mobilegl_gbm.so, aliases, vendor JSONs, client.conf, GLX/GBM env drop-ins
```
Running clients keep the old inode; restart the client, or `run-plasma.sh` for KWin/plasmashell. Build server and client from the **same commit** (both stamp `git rev-parse HEAD`), else the logs WARN "compatible wire with different build". Fallback in-container build (slow): `scripts/sync-src.sh` + anland `mobilegl-tools/anland-build-client.sh`.
**KWin (anland backend / kwin.patch) - built inside the container**
```sh
bash scripts/kwin-stage.sh build # stage CR-stripped patch+backend+startup script, kwprep.sh, background sync-build-kwin.sh
printf 'tail -5 /root/kwin-build.log\n' | bash scripts/ct.sh kw # wait for "== ALL DONE =="
adb shell 'su -c "sh /data/local/tmp/anl/run-plasma.sh"'
```
`sync-build-kwin.sh` (anland `producers/kde/Arch_v5/`) copies only the backend sources, then `ninja -j4`, installs `kwin_wayland`, `libkwin.so.6.7.4`, the patched screencast plugin and `/opt/mobilegl/bin/mobilegl-startup.sh` by atomic rename. `kwprep.sh` is what applies changed `kwin.patch` hunks to core KWin files. Repo-root `libdisplay_producer/` is not synced by either. `kwin-stage.sh` is assembled from those two scripts and was not run as one unit yet.
**Unit tests (no device)** - in WSL (the MSVC build of this branch is broken):
```sh
MSYS2_ARG_CONV_EXCL='*' wsl -d archlinux -- bash /mnt/c/<worktree>/.claude/skills/anland-mobilegl-plasma/scripts/wsl-test.sh MultiSessionTest TwinOwnershipTest
MSYS2_ARG_CONV_EXCL='*' wsl -d archlinux -- bash -lc 'cd ~/mgl-anl-bld && ctest -R "MultiSession|TwinOwnership" -E DirectVulkan --output-on-failure'
```
`wsl-all.sh` builds and runs every unit test. Never run DirectVulkan integration tests; never two ctest runs at once.
## Switching backends
In the app: Settings > Connection > MobileGL desktop > Renderer backend, then Stop desktop and open the app. Or `adb shell 'su -c "sh /data/local/tmp/anl/switch.sh DirectGLES"'`, which does the same (saves the setting through the launch extra, STOPs the service, reopens; clears a stale `debug.mobilegl.backend`). No setprop, no file to edit in the container: the session copies the published backend into `/etc/mobilegl/backend` on its next start. `cyc.sh` keeps whatever is set.
## System-wide vendor and fallback
Installed by `xdeploy.sh` (and anland's `anland-build-client.sh`), so any process in the container gets MobileGL through the stock libglvnd/libgbm:
| File | Does |
|---|---|
| `/usr/share/glvnd/egl_vendor.d/10_mobilegl.json` | EGL vendor, asked before the system's `50_*.json` |
| `/opt/mobilegl/share/glvnd/egl_vendor.d/50_mobilegl.json` | same JSON, for per-process forcing with `__EGL_VENDOR_LIBRARY_FILENAMES` |
| `/etc/mobilegl/client.conf` | `KEY=value` defaults for every client (transport, data, endpoint); rewritten on deploy |
| `/etc/mobilegl/backend` | the backend (the session's `sync-backend` step copies the app's choice in); wins over a `MOBILEGL_BACKEND_TYPE` line in client.conf |
| `/etc/environment.d/10-mobilegl.conf` | `__GLX_VENDOR_LIBRARY_NAME=mobilegl`, `GBM_BACKEND=mobilegl` for the systemd user manager (all Plasma services and what they start, terminals included) |
| `/etc/profile.d/mobilegl.sh` | the same two for login shells (`bash -l`, `su -l`, ssh, `droidspaces run bash -l`) |
Precedence is environment > `/etc/mobilegl/backend` (backend only) > client.conf > built-in; `MOBILEGL_CONFIG_FILE` / `MOBILEGL_BACKEND_FILE` name other files (empty = off); a server process never reads them.
**Fallback.** Before bringing anything up the client probes the configured endpoint (one non-blocking connect, `MOBILEGL_IPC_PROBE_TIMEOUT_MS`, default 250, 0 = off; a refused abstract socket answers in ~0.2 ms). With no server: the EGL vendor returns `EGL_NO_DISPLAY` and no devices (glvnd moves on to the other vendor), the GLX vendor fails `__glx_Main` (libGLX falls back to the vendor Xwayland names), and `mobilegl_gbm` fails `create_device` (libgbm falls back to the device's own backend). Client queries (`eglQueryString(EGL_NO_DISPLAY)`, `eglGetProcAddress`) never bring a session up. MobileGL also steps aside for a GBM device another backend created. It no longer steps aside for `LIBGL_ALWAYS_SOFTWARE=1` (918d40dd): that is Mesa's software-renderer selection, not a reason to disable MobileGL's entry points, so a process that sets it (a software Xwayland included) is still served by MobileGL while a server answers. MobileGL never opens an X connection to a display its own process serves (`MG_Util/X11/DisplayGuard.h`; `MOBILEGL_X11_DIAL=0` forbids all), which is what made a glamor Xwayland deadlock on itself before. Show it without stopping the real server:
```sh
sed 's|^MOBILEGL_IPC_CONTROL=.*|MOBILEGL_IPC_CONTROL=unix:@nobody|' /etc/mobilegl/client.conf > /tmp/down.conf
sudo -u swung0x48 env -i HOME=/home/swung0x48 PATH=/usr/bin XDG_RUNTIME_DIR=/run/user/1000 WAYLAND_DISPLAY=wayland-0 \
MOBILEGL_CONFIG_FILE=/tmp/down.conf eglinfo -B -p wayland # vendor = the other one, ~0.1 s
```
## Test clients and how to verify
X11 on the GPU has its own driver, `scripts/x11-verify.sh` (preflight, measure before/after with glxgears at `vblank_mode=0` on both GLX paths (presentation throughput only: glxgears is fixed-function GL, which MobileGL does not implement, so its window is black by design), deploy-client/-kwin/-server, check, apps, stop); `scripts/device/x11-measure.sh` refuses to load the phone below 40% battery.
Inside the container as root (`printf '...' | bash scripts/ct.sh <chan>`), `mgrun offscreen <cmd>` runs a client as swung0x48 in the live session through a login shell, with nothing but the surface mode and the log path set (log `/tmp/mgl-run.client.log`, override base with `MGLOG=/tmp/x.log`); a plain `env -i ... bash -l -c '<cmd>'` as swung0x48 gets MobileGL the same way:
```sh
mgrun offscreen eglinfo -B ; mgrun offscreen glxinfo -B
timeout 25 mgrun offscreen glmark2-es2-wayland -s 1280x720 --run-forever > /tmp/gm.out 2>&1 &
sleep 8; grep -a "presented through" /tmp/mgl-run.client.log
```
Chrome: `bash scripts/chrome-launch.sh <tag> [flags]` (log `/tmp/mgl-chrome-<tag>.client.log`, screenshot `ch-<tag>.png`; `CHROME_GPU=in-process` puts the GPU back in the browser, which cannot recover from a device loss).
Video: Chrome decodes in hardware. The GPU process's render node has a VA-API driver in the container (`/usr/lib/dri/msm_drm_drv_video.so`, DroidSpaces' V4L2 driver): Chrome allocates its frames with `vaCreateSurfaces` and exports them (`vaExportSurfaceHandle`, one fd, R8 + GR88 layers) - the driver's own buffers, never GBM ones - and imports each as an NV12 (P010 for 10-bit) EGLImage bound to `GL_TEXTURE_EXTERNAL_OES`. MobileGL takes such a FOREIGN YUV dma-buf through its labelled CPU-copy fallback: the server maps it and copies it into a YUV AHardwareBuffer of its own (`AHardwareBuffer_lockPlanes`) at the reader's first use in each frame (any present, publishing flush or native fence), then converts that into the texture's RGBA level on the GPU (Espryt: `GL_EXT_YUV_target` with the import's colour hints, `MOBILEGL_YUV_DRIVER_CONVERSION=1` for the driver's external sampler; Magma: `VkSamplerYcbcrConversion` on the AHB's external format). A server-allocated NV12/P010 buffer (GBM `gbm_bo_create(NV12)`) needs no copy. `MOBILEGL_CHROME_VIDEO_DECODE=software` in `mobilegl-startup.sh chrome` brings back `--disable-accelerated-video-decode`. Check a video with `scripts/probes/cdpmedia.py <port> <s>` in the container (CDP `Media.enable`: `kVideoDecoderName = VaapiVideoDecoder`, `kIsPlatformVideoDecoder = true`; `CDP_NAVIGATE=<url>` / `CDP_EXPR=<js>`), which needs Chrome started with `--remote-debugging-port` and a non-default `--user-data-dir` (a fresh profile also needs `--password-store=basic`, else page loads wait forever on KWallet), and grep Chrome's log for `exit_code` (a GPU-process restart). `scripts/probes/yuvprobe.c` pixel-checks foreign NV12/P010 imports, their per-frame refresh and a GBM NV12 buffer (`mgrun offscreen mgl-yuvprobe`, exit 0 = pass). KWin's own NV12 path (it splits a YUV buffer into R8 + GR88 imports) is not served: MobileGL imports no single-channel dma-bufs, so KWin advertises no YUV format over linux-dmabuf. A vendor-agnostic replacement driver (MobileVA: VA-API on Android MediaCodec, decoding into server YUV images with no CPU copy, the current driver kept as an A/B fallback) is planned, not built: `docs/MobileVA/plan.md`.
Device loss: `setprop debug.mobilegl.inject_device_lost_pid <pid>` (as root) loses the server session of the client whose pid - as it sees itself in the container - is `<pid>`, once per value, on any backend and whether or not it presents; `debug.mobilegl.inject_device_lost_at N` instead loses whichever session makes the N-th device check (Espryt presents and read-backs only). `bash scripts/chrome-recover.sh <in-process|process> [rounds]` checks that Chrome repaints after such a loss without a restart (battery-guarded, stops below 40%). `bash scripts/kwin-recover.sh [rounds]` loses KWin's own session (default twice) and checks that KWin restarts compositing on a fresh session - same KWin, plasmashell and client processes, the screen still animating (glmark2 on Wayland, glxgears on X11, `CHROME=1` adds Chrome) - which needs the anland backend + kwin.patch reset handling deployed (`kwin-stage.sh build`).
Probes: `scripts/probes/texfmt.c` (texture formats keep alpha?), `dmahash.c` (hash a process's dma-bufs), `yuvprobe.c` (YUV dma-buf sampling, `gcc -O1 /root/yuvprobe.c -o /usr/local/bin/mgl-yuvprobe -lEGL -lGLESv2 -lgbm -lm`), `cdpmedia.py` (which decoder a Chrome page uses); build in the container, e.g. `gcc -O1 /root/texfmt.c -o /usr/local/bin/mgl-texfmt -lEGL`, run with `mgrun offscreen`.
GPU hangs: a shader that never ends stops the WHOLE GPU (every process, MobileGL or not) until the kernel resets it - ~2 s, or ~10 s ("Preemption Fault" in dmesg) when a higher-priority context waits; nothing in user space shortens one stall. What the server does is end the guilty session so it cannot hang the GPU again (Magma: event-bracketed submissions + `mgl-gpu-watch`, budget `MOBILEGL_GPU_HANG_BUDGET_MS` / `debug.mobilegl.gpu_hang_budget_ms`, default 2000; Espryt: the driver's GUILTY reset status, which it reports after the ~2 s reset only). Repro: `scripts/probes/hangclient.c` (Wayland + GL 3.3 core; `-H 60 -N 1 -E 60` hangs every 60 frames, `-H -1` is a frame-gap observer; build with wayland-scanner's xdg-shell files, `-lwayland-client -lwayland-egl -lEGL -lOpenGL -lm`), and `gpuprobe.c` (NDK, plain adb shell; `gpuprobe 30 high` is a high-priority GLES context outside MobileGL - it both measures the device-wide stall and forces the 10 s preemption path).
A result counts only if ALL hold:
- client log says `presented through linux-dmabuf shared images` (not `wl_shm`; `could not be presented through a linux-dmabuf shared image` = fell back);
- `bash scripts/shot.sh g 2 1` gives two different hashes while the client animates (a "fast" score can mean frames are not shown);
- `adb logcat -b crash -d` and `adb logcat -d | grep -E "Fatal signal|Abort message|E MobileGL"` are clean (a frozen window is usually a dead server);
- for plasmashell verdicts, the sticky software renderer is off (below) and `/tmp/mgl-plasmashell.client.log` is freshly written.
Reference (glmark2-es2-wayland 1280x720, zero-copy vs wl_shm): Espryt 187 vs 49, Magma 158 vs 34. Rerun any surprising pass.
## Logs
| What | Where |
|---|---|
| KWin client side | container `/tmp/mobilegl-compositor.client.log` |
| plasmashell / ksplash | `/tmp/mgl-plasmashell.client.log`, `/tmp/mgl-ksplash.client.log` (user drop-ins `~/.config/systemd/user/plasma-{plasmashell,ksplash}.service.d/mobilegl-log.conf`) |
| mgrun / Chrome | `/tmp/mgl-run.client.log`, `/tmp/mgl-chrome-<tag>.client.log` (+ `/tmp/chrome-<tag>-out.log`) |
| Server | `adb logcat -s MobileGL`; file `/data/data/com.anland.consumer.mobilegl/files/mobilegl-server.server.log` |
| Native crashes | `adb logcat -b crash -d`; container `coredumpctl list` |
| Session / KWin stderr | container `journalctl -u desktop-session --no-pager`, `journalctl --no-pager --since -2min \| grep kwin_wayland` |
| Display daemon | `/data/local/tmp/anland-mobilegl/display-daemon.log` |
| Desktop start/stop (app's su script) | `/data/local/tmp/anland-mobilegl/desktop.log`, `container-start.log`; logcat `-s AnlandMobileGL` |
| Session wait / backend sync | container `journalctl -u desktop-session --no-pager` ("waiting for the MobileGL server ...") |
`MOBILEGL_LOG_FILE_PATH=/tmp/x.log` produces `/tmp/x.client.log` (and `.server.log` for forwarded lines); files are truncated on open, so one base per process. Client builds log at INFO. Symbolize server frames with `$ANDROID_NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/llvm-addr2line.exe -Cfe build-android/libMobileGL.so <offset>`.
## Pitfalls
- **pkill -f self-match**: a `ct.sh`/`droidspaces run bash -lc "<script>"` process carries the script in its argv; `pkill -f chrome` kills the runner. Use `pkill -x`.
- **Root-owned /tmp files**: a log created by a root-run client cannot be reopened by swung0x48 later (no log appears). `rm -f` it as root first.
- **Sticky Plasma software renderer**: after any server crash Plasma writes `[QtQuickRendererSettings] SceneGraphBackend=software` into `~swung0x48/.config/kdeglobals`; plasmashell then renders on the CPU and screenshots still look fine (tray icon "正在使用的软件渲染器"). `mobilegl-startup.sh plasma` deletes it at every session start; within a running session that hit a crash, restart the session (`run-plasma.sh`) before any verdict.
- **Lock screen**: autolock is off (`kscreenlockerrc [Daemon] Autolock=false`); a real lock can only be left by typing the password (logind lock/unlock is not supported for this session type - `device/unlock.sh` is unverified). Test the greeter with `/usr/lib/kscreenlocker_greet --testing` and kill it.
- **CRLF**: `core.autocrlf=true` here; anland's backend sources and `sync-build-kwin.sh` are CRLF in the Windows checkout. Strip CR before anything runs on Linux/Android (`tr -d '\r'`; `ct.sh`, `push-tools.sh`, `kwin-stage.sh` do). This skill has a `.gitattributes` forcing LF.
- **Display daemon**: the app starts it; the session's `wait` step keeps KWin from starting without it (a KWin that cannot reach it logs "failed to connect to display daemon at /run/anland-mobilegl/display.sock" and exits in ~3 s). Anything started from the app's `su` must leave the app's cgroup (`echo $$ > /sys/fs/cgroup/cgroup.procs`) or a force-stop kills it.
- **Device power/connection**: low battery or the screen turning off (30 s default) can kill the SurfaceView - `svc power stayon true`; wireless adb `ip:port` changes per pairing - never pin `-s HA27Q3LQ`, use `ANDROID_SERIAL` if several devices are attached.
- **Container vs phone paths**: container `/tmp` is a different place from the phone's `/data/local/tmp`; move files via `/mnt/Droidspaces/arch-kde-mgl/root` (container `/root`) or `/data/local/tmp/anland-mobilegl` (= container `/run/anland-mobilegl`).
- **Never overwrite a mapped .so in place** (container or APK while running): copy to a new inode and `mv -f`; the APK swap force-stops the app first.
- **Input**: plain `adb shell input` is blocked - use `su -c input`; anland grabs the touchscreen, so if `input tap` does nothing use `input mouse tap x y`. Never `debuggerd -b` a container process (signal 35 kills glibc processes).
- **linux-dmabuf**: the client must use `create` + roundtrip, never `create_immed` (KWin answers a failed immediate import with a protocol error that kills the client).
- **Cross-session bugs**: noise / another window's pixels after some client starts or exits = process-global state in the multi-session server (handles are per client, FBO/VAO per context). Repro with `kscreenlocker_greet --testing`.
- `/etc/environment` leaks the baseline session's driver variables through pam_env (and, via `/usr/lib/environment.d/99-environment.conf`, into the user manager); `mobilegl-startup.sh` unsets them - keep that when editing it.
- **Shared log path**: Xwayland inherits KWin's `MOBILEGL_LOG_FILE_PATH`; any line a process logs opens (truncates) that file. MobileGL stays silent in processes it does not serve, but give any extra client its own `MOBILEGL_LOG_FILE_PATH`.
- **Stale per-process overrides**: an `__EGL_VENDOR_LIBRARY_FILENAMES` / `MOBILEGL_*` left in a unit drop-in or the user manager's environment (`systemctl --user show-environment`) still wins over the system files; `run-plasma.sh` (terminate-user) clears the manager's.
- `handoff` mentions a `kwin_wayland` logging shim and `/tmp/mgl-kwin-<pid>.log`: stale - `/opt/mobilegl/kwin/bin/kwin_wayland` is now the real binary and logs to `/tmp/mobilegl-compositor.client.log`.
## House rules
- Work in a git worktree, never in the shared main checkout or its build dirs; worktrees need `GIT_LFS_SKIP_SMUDGE=1`.
- Commit with `git commit --no-verify`, one short sentence, **no** `Co-Authored-By` trailer.
- Never run the DirectVulkan integration tests (`ctest -E DirectVulkan`).
- No external project names ("Mesa", "Zink", ...) in source code or comments; describe the technique.
- Vendor-agnostic only on the zero-copy path: AHB, EGL_ANDROID_*, VK_ANDROID AHB import, sync_file, dma-buf, libgbm ABI - no kgsl/gralloc layouts/QCOM modifiers.
- Identity caches key on monotonic lifetime ids, never GL names or pointers.

# Reproducing the MobileGL + anland + KDE Plasma setup from source
This is the from-scratch path for a NEW development machine and/or a NEW phone. `SKILL.md` covers the
day-to-day loop once everything below exists. Paths and names that are specific to the original
machine are listed in step 9: set them in `scripts/env.sh` (or the environment) before running anything.
## 0. What you need
**Phone.**
- arm64 Android 11+ with **root**. KernelSU is what this was built on; the scripts only need `su -c`.
- A Vulkan 1.1 driver with `VK_ANDROID_external_memory_android_hardware_buffer` for Magma, and/or GLES 3.2 + EGL_ANDROID_native_fence_sync for Espryt. Nothing vendor-specific is used: no kgsl and no vendor ioctls, only AHardwareBuffer, sync_file and the vendor's public GLES/Vulkan.
- About 20 GB free for the container image.
**Development host.**
- The scripts are written for **Windows + Git Bash** with WSL (`archlinux` distro) for the unit tests and the cross build.
- A Linux host works too: drop the `cygpath`/`MSYS_NO_PATHCONV` handling in `env.sh`, and run the WSL parts natively.
- Tools:
- `adb`, CMake >= 3.22, Ninja, Python 3 (+ Pillow for screenshots/recording).
- Android NDK **27.2.12479018**.
- JDK 17 and Android SDK platform 36 (for the APK).
- In the Linux environment: clang/lld/llvm of ONE major version (a mismatched lld breaks `ld.lld`), cmake, ninja.
## 1. Sources
```sh
# MobileGL: branch feat/disaggregated (everything here is on it)
git clone https://github.com/MobileGL-Dev/MobileGL.git && cd MobileGL
git checkout feat/disaggregated
GIT_LFS_SKIP_SMUDGE=1 git submodule update --init --recursive
# 3rdparty/glslang is the MobileGL-Dev fork (main); its External/spirv-tools must be populated
# (glslang's own update_glslang_sources.py, or copy it from another checkout).
# Keep builds out of a shared checkout: work in a worktree (GIT_LFS_SKIP_SMUDGE=1 git worktree add ...).
# anland: branch legacy-mobilegl-unified (KWin backend + patch, startup script, APK, daemon module)
git clone https://github.com/MobileGL-Dev/anland.git && cd anland # the fork that carries this branch
git checkout legacy-mobilegl-unified
```
Build the server (APK) and the client (container) from the **same MobileGL commit**: both stamp
`git rev-parse HEAD`, and a mismatch logs "compatible wire with different build".
## 2. Phone base: root, Droidspaces, display daemon
1. **Root** with KernelSU (or another `su` provider).
2. **Droidspaces:** install the module and its app. Containers live under `/data/local/Droidspaces/Containers/<name>/`, and the CLI is `/data/local/Droidspaces/bin/droidspaces`.
3. **anland display daemon** (KernelSU/Magisk module `anland-daemon`):
- Build it from the anland repo with `build_daemon_android.sh`, then package it with `build_magisk_module.sh`, which uses `magisk_module/`. Flash it and reboot.
- The module's `service.sh` starts the original daemon on `/data/local/tmp/display_daemon.sock`.
- The MobileGL session uses a SECOND instance of the same binary on `/data/local/tmp/anland-mobilegl/display.sock`: see `scripts/device/restart-daemon.sh`, which also chmods the directory and socket.
## 3. The container
Use an **Arch Linux ARM (aarch64, glibc) KDE Plasma Wayland rootfs** that has a systemd `desktop-session.service` running the desktop as a normal user with `PAMName=login`. A ready-made one is the Arch KDE "Wayland" image from Droidspaces RootFS Desktop Builder (see anland `doc/UserManual/anland_guide.md`, "Use prebuilt packages or a RootFS"). Or install `plasma-desktop`, `plasma-workspace`, `libglvnd`, `xorg-xwayland`, `base-devel`, `cmake` and `ninja` on plain Arch Linux ARM and write the service yourself.
Import it into Droidspaces as `arch-kde-mgl`. The default name is in `env.sh`. Reference `container.config` keys:
```
enable_gpu_mode=1
net_mode=host
bind_mounts=/data/local/tmp/display_daemon.sock:/run/display.sock,/data/local/tmp/anland-mobilegl:/run/anland-mobilegl
run_at_boot=0
```
- **Host networking:** it is required. The MobileGL server listens on the ABSTRACT socket `@anland-mobilegl`, which crosses into the container only when the network namespace is shared.
- **The anland-mobilegl directory:** create `/data/local/tmp/anland-mobilegl` on the phone before the first start, mode 777.
- **Desktop user:** the default is `swung0x48` (`MGL_DESKTOP_USER`). Create your own and point `desktop-session.service` at it.
- **Starting it:** `droidspaces -C .../container.config start`. Android root sees the rootfs at `/mnt/Droidspaces/<name>`, which `CT_ROOT` in `env.sh` relies on.
- **Container tools:** install them with `bash scripts/push-tools.sh` once the container runs.
## 4. MobileGL server and the anland APK
```sh
bash scripts/build-android.sh # -> <worktree>/build-android/libMobileGL.so
```
The script runs, with the NDK toolchain:
```
-DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=android-30 -DCMAKE_BUILD_TYPE=RelWithDebInfo
-DMOBILEGL_PIPE_PUSH=ON -DMOBILEGL_BUILD_DISAGGREGATED=ON -DMOBILEGL_BUILD_DISAGGREGATED_INPROC=ON
-DMOBILEGL_BUILD_TEST=OFF -DMOBILEGL_BUILD_BENCHMARK=OFF
```
APK, from anland `consumers/anland_v5/android_consumer` (details in its `MOBILEGL.md`):
```sh
mkdir -p dist/arm64-v8a && cp <worktree>/build-android/libMobileGL.so dist/arm64-v8a/
MOBILEGL_DIST=$PWD/dist ./gradlew :app:assemblePlainDebug \
-PanlandNdkVersion=27.2.12479018 -PmobileglApplicationId=com.anland.consumer.mobilegl \
-PanlandDefaultSocket=/data/local/tmp/anland-mobilegl/display.sock
adb install -r app/build/outputs/apk/plain/debug/app-plain-debug.apk
```
- **Grant root:** the app needs root for its helper; approve it in KernelSU.
- **Reinstall with another signing key:** that changes the UID, so grant root again (anland `mobilegl-tools/ksu_grant.c` does it from a shell). Don't uninstall to fix a signature clash: that wipes the app data.
- **Later server-only changes:** swap just the library into the installed APK (`scripts/cyc.sh` / `device/swap.sh`) instead of rebuilding the APK.
## 5. MobileGL client in the container
Pick one of these two:
- **Cross build** (fast, from WSL or Linux):
1. `bash scripts/xsysroot/refresh-sysroot.sh` exports the container's headers and libraries to `~/sysroots/arch-kde-mgl` and installs `~/sysroots/aarch64-arch.cmake`. Re-run it after container package upgrades.
2. `bash scripts/xbuild.sh`, then `bash scripts/xdeploy.sh`.
- **Native build in the container** (slow, no WSL): `scripts/sync-src.sh` copies the worktree to `/root/mobilegl-unified-src`, then run anland `producers/kde/Arch_v5/mobilegl-tools/anland-build-client.sh` inside (g++, `-DMOBILEGL_BUILD_DISAGGREGATED=ON`, Release).
Either route installs the same files, renamed into place so running clients keep their old mapping:
| File | What it is |
|---|---|
| `/opt/mobilegl/lib/libMobileGL.so` (+ `libEGL`/`libGL` aliases) | the client library |
| `/usr/share/glvnd/egl_vendor.d/10_mobilegl.json` | system-wide EGL vendor; sorts before the distribution's `50_*.json`, which serves whenever MobileGL declines (no server reachable) |
| `/opt/mobilegl/share/glvnd/egl_vendor.d/50_mobilegl.json` | per-process forcing |
| `/usr/lib/libGLX_mobilegl.so.0` | GLX vendor |
| `/usr/lib/gbm/mobilegl_gbm.so` | GBM backend (zero-copy window buffers) |
| `/etc/mobilegl/client.conf` | `MOBILEGL_TRANSPORT=spawn`, `MOBILEGL_IPC_DATA=shm`, `MOBILEGL_IPC_CONTROL=unix:@anland-mobilegl` |
| `/etc/mobilegl/backend` | `DirectVulkan` (Magma) or `DirectGLES` (Espryt) |
| `/etc/environment.d/10-mobilegl.conf`, `/etc/profile.d/mobilegl.sh` | `__GLX_VENDOR_LIBRARY_NAME=mobilegl`, `GBM_BACKEND=mobilegl` |
## 6. KWin 6.7.4 with the anland backend, and Xwayland
The MobileGL session runs a rebuilt KWin from `/opt/mobilegl/kwin`, so the packaged one stays untouched.
1. **Source tree:** in the container, unpack KWin 6.7.4 to `/root/mobilegl-build/kwin-6.7.4`, apply anland `producers/kde/Arch_v5/kwin.patch`, and overlay `producers/kde/anland_backend_Arch_v5/src/backends/anland` into `src/backends/anland`. Also take the current `common/` and `libdisplay_producer/`, as `mobilegl.md` there says.
2. **Configure:**
```sh
cmake -S kwin-6.7.4 -B kwin-6.7.4/build -G Ninja -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib -DBUILD_TESTING=OFF
```
3. **Build and install:** run `producers/kde/Arch_v5/sync-build-kwin.sh` (`ninja -j4`). It installs `kwin_wayland` + `libkwin.so.6.7.4` into `/opt/mobilegl/kwin/{bin,lib}`, the patched screencast plugin in place (the original is kept beside it), and `/opt/mobilegl/bin/mobilegl-startup.sh`.
- From the dev host, `bash scripts/kwin-stage.sh build` does steps 1–3 incrementally: `kwprep.sh` applies changed patch hunks.
4. **Xwayland:** the anland-patched Xwayland 24.1.13 comes from `producers/kde/Arch_v5/build.sh` (makepkg, as a normal user; it builds the anland KWin and Xwayland packages). A prebuilt anland rootfs already has it.
5. **Session hook:** add `/etc/systemd/system/desktop-session.service.d/mobilegl.conf`:
```ini
[Service]
ExecStart=
ExecStart=/opt/mobilegl/bin/mobilegl-startup.sh plasma
Environment=ANLAND_SOCKET=/run/anland-mobilegl/display.sock
Environment=QT_LOGGING_RULES=kwin_*.info=true
```
`mobilegl-startup.sh plasma` writes the user drop-in for `plasma-kwin_wayland.service` (the `/opt/mobilegl/kwin` binary, `ANLAND_MOBILEGL=1`, `MOBILEGL_IPC_SURFACE=server`, `GBM_BACKEND=mobilegl`) and runs `startplasma-wayland`.
## 7. Bring it up
Nothing has to be started by hand, and the order no longer matters: **open the app** (its launcher
icon, or `am start -n com.anland.consumer.mobilegl/com.anland.consumer.MainActivity` with no extras).
That is the single trigger. The app starts its foreground service and runs its bundled
`mobilegl-desktop.sh up` as root, which:
1. starts the display daemon if it is not running;
2. publishes the backend (the app setting "Renderer backend", default DirectGLES) to
`/data/local/tmp/anland-mobilegl/backend`;
3. starts the container if it is stopped;
4. starts `desktop-session`, which waits for the server and the daemon socket, copies the backend into
`/etc/mobilegl/backend` and runs Plasma.
Cold start to a desktop takes about 8-12 s. `scripts/device/bringup.sh` wakes the phone, dismisses the
keyguard, opens the app and prints the timeline. To change the backend, use the app setting and then
Stop desktop and reopen, or run `scripts/device/switch.sh DirectGLES|DirectVulkan`. Do not use
`setprop debug.mobilegl.backend`: it overrides the setting until the next reboot. **Stop desktop**
(the notification action) stops the session and the container.
**After a phone reboot:** wireless adb does not come back by itself. Re-enable it on the phone
(Developer options > Wireless debugging), then `adb connect <ip>:<port>`; the port changes. After
that, open the app as above. See SKILL.md "Starting, idling, stopping".
## 8. Verify
- **Plasma:** it appears in the app. The tray must NOT show the "software renderer" icon; if it does, delete `SceneGraphBackend=software` from the user's `kdeglobals` and restart.
- **Plain shell:** in a plain container shell as the desktop user, `eglinfo -B` names MobileGL, and `glxinfo -B` from a login shell does too.
- **Wayland client:** `timeout 25 mgrun offscreen glmark2-es2-wayland -s 1280x720`. The log must say `presented through linux-dmabuf shared images`.
- **Chrome:** `bash scripts/chrome-launch.sh t1` gives windows with correct icons.
- **Resize and lock:** BACK toggles the extra-keys bar (resize); lock/unlock resumes the desktop. `rtest.sh` in the scratch dir checks both.
- **Unit tests:** `bash scripts/wsl-all.sh` in WSL. NEVER run the DirectVulkan integration tests.
## 9. Machine-specific values to change
| Value | Original | Where |
|---|---|---|
| MobileGL worktree | this skill's worktree | `MGL_WORKTREE` (auto) |
| scratch dir | `%LOCALAPPDATA%/Temp/anl` | `ANL_DIR` |
| NDK | `<SDK>/ndk/27.2.12479018` | `ANDROID_NDK` |
| anland worktree | `%USERPROFILE%/AndroidStudioProjects/anland/.claude/worktrees/mgl-unified` | `ANLAND_WORKTREE` (`kwin-stage.sh`) |
| APK id | `com.anland.consumer.mobilegl` | `MGL_PKG` |
| container | `arch-kde-mgl` | `MGL_CONTAINER` |
| desktop user | `swung0x48` | `MGL_DESKTOP_USER` + `desktop-session.service` |
| WSL distro | `archlinux` | `WSL_DISTRO` (`xbuild.sh`, `wsl-*.sh`) |
| cross build dir | WSL `~/mgl-xbuild-a64` | `MGL_XBUILD_DIR` |
| phone | Lenovo TB321FU, Adreno 750 | nothing: no serial is pinned; with several devices set `ANDROID_SERIAL` |
**Thermals:** a phone vendor's thermal daemon may throttle charging while the screen is on during long sessions. That is not part of this setup.

# chrome-recover.sh <in-process|process> [rounds] - does Chrome repaint after a GPU device loss,
# without a restart? Starts Chrome (chrome-launch.sh, CHROME_GPU=<mode>) on an animated WebGL page,
# then per round: screenshots (the page must animate), loses the session of Chrome's GPU client with
# the server's pid-targeted debug knob (debug.mobilegl.inject_device_lost_pid; the pid as Chrome sees
# itself in the container), waits, and screenshots again. A round PASSES when the server latched
# that pid's session, the browser process is the same one (no restart), a GPU client is drawing on a
# NEW server session, and the screen still animates. Stops early below MIN_BATTERY percent.
#
# in-process the GPU in the browser process (the startup script's default today): the target is
# the browser itself; recovery needs ANGLE to make a new native context.
# process the GPU in its own process (MOBILEGL_CHROME_GPU=process): the target is the GPU
# process; Chrome restarts it after the loss, so the next round's target is a new pid.
#
# Deploy first (same MobileGL commit on both sides; see SKILL.md):
# bash scripts/build-android.sh && bash scripts/cyc.sh pre # server -> APK, restarts the session

# Starts animated clients (glmark2-es2-wayland: Wayland, zero-copy shared images; glxgears: X11 through
# Xwayland's GLX; with CHROME=1 also Chrome on an animated WebGL page), then per round loses the server
# session of KWin with the pid-targeted debug knob (debug.mobilegl.inject_device_lost_pid, KWin's pid as
# it sees itself in the container), waits, and checks. A round PASSES when:
# - the server latched KWin's session (the server log file: "injected:pid=<kwin>"; logcat is too small);
# - KWin, plasmashell and every test client are the SAME processes (nothing restarted);
# - KWin restarted compositing on a fresh session (its journal: "compositing restarted on a fresh
# MobileGL session"; its client log: one more "RECOVERED");
# - the screen still animates (shot.sh hashes differ) and the clients keep presenting;
# - no native crash (logcat -b crash).
# Between rounds the knob is reset to 0 while the clients run, which re-arms it for the same pid.
# Stops early below MIN_BATTERY percent (the phone drains faster under load than USB charges it).

// yuvprobe.c - pixel check of YUV dma-buf sampling through MobileGL (GL_OES_EGL_image_external).
//
// gcc -O1 yuvprobe.c -o /usr/local/bin/mgl-yuvprobe -lEGL -lGLESv2 -lgbm
// mgrun offscreen mgl-yuvprobe # exit 0 = every check passed
//
// What it does, in an ES 3.0 context on a pbuffer:
// 1. FOREIGN NV12 (and P010): a dma-buf from /dev/dma_heap/system - a buffer the MobileGL server
// did not allocate, as a video decoder's would be - with padded pitches and a gap before the
// chroma plane, filled with four vertical bars (red, green, blue, white) in BT.709 narrow
// range. Imported with eglCreateImage(EGL_LINUX_DMA_BUF_EXT) and its colour hints, bound to
// GL_TEXTURE_EXTERNAL_OES, drawn through a samplerExternalOES shader into an RGBA8 FBO and read
// back: each bar must come out its colour. The buffer is then rewritten with the bars in
// reverse order and, after a native fence (what ends a frame for an offscreen producer), drawn
// again: the new order must show (the server refreshes a foreign buffer at each frame).
// 2. GBM NV12: gbm_bo_create(NV12) through the mobilegl GBM backend (a server-allocated YUV
// buffer, zero-copy), its planes printed, imported and sampled once (content undefined; the
// check is that every call succeeds).
// Also prints the dma-buf formats/modifiers EGL lists for NV12/P010.

# glvnd vendor ABI headers
'libeglabi.h' and 'GLdispatchABI.h' from libglvnd (MIT), copied verbatim with their own licence
headers intact.
They are here because MobileGL implements the *vendor* half of glvnd's EGL ABI - the side a library
exposes so the system's 'libEGL.so.1', which IS glvnd, can dispatch to it. The distribution ships
the runtime but not these headers in the base image, and a vendored copy of two MIT headers is a
smaller dependency than a build-time download of a source tree.
Upstream ABI version implemented: 'EGL_VENDOR_ABI_MAJOR_VERSION' 0 (the header pins it).

# MobileGL can serve as a glvnd EGL vendor - the library the system's libEGL.so.1 dispatches to -

# an address that resolves to another libEGL in the process is a call back into the dispatcher.

# and a process that loaded the system libEGL first wins. Marking the entry points protected says
# the same thing in the source, except the platform's own GL/EGL headers declare them default and

// what displaces an answer is what the SERVER sends, not what the client emits;

// window 2 2,500 17.27 s
// window 4 1,644 11.02 s
// and the round trip does NOT grow as the window deepens (5,285 / 4,082 us against 5,672
// at 1), which is the measurement that says the ~5 ms is a WAKEUP the server batches away
// rather than its apply throughput - so amortising four creates per wakeup is a real 2.6x.

// This was the LAST unguarded frontend read on the multi-draw apply path, and it sat
// twenty lines above the function that retired its neighbour. It asked
// `gPipeInputs->GetBufferBindingSlot(BufferTarget::DrawIndirect)` and then
// `EnsureBufferResource(<frontend object>)` - a registry lookup keyed by the client's
// identity, which is §4.4's rule and not only the allocator's. Under run-ahead that is
// `Fatal{UnmigratedPipeInput, "GetBufferBindingSlot@DrawArrays"}` on every batch the
// indirect tiers execute: 18 lane entries, and the only thing standing between the flip
// and a green lane once the fill race was fixed.
//
// WHAT IT IS NOT: a data dependency. The tier does not want the client's indirect
// buffer - it never reads a byte of it. It binds its OWN scratch command buffer
// (g_indirectCommands) and wants to put back the name that was there. So the answer is
// not "migrate the value" (which is what P8 owes for the ordinary indirect draw path);
// it is "ask the side that did the binding". ID-133's escalation (iii) legalised the
// pull instead, at the price of a rendezvous on every plain glMultiDraw* on the DEFAULT
// tier - a real cost on the shipping arm, paid to make a lane green. ID-136 withdraws
// that escalation and retires the read, in the commit that adds this arm.
//
// WHY MGPipeApplier().VerbIndirectBuffer IS THE WHOLE ANSWER ON THIS ARM: with a
// transport, the ONLY writer of this process's GL_DRAW_INDIRECT_BUFFER outside this
// function is DirectGLES.cpp's DrawSyncBit::IndirectBuffer arm, which binds from exactly
// that handle and nothing else. So "what was bound" IS "what the verb's record named",

// Espryt 0b, the first Track H slice: the DENSE, {slot, gen}-keyed twin table that replaces
// StateBackendObjectRegistry's UnorderedMap<StateObject*, Entry>.
//
// What changes, and why each of them is the point:
//
// * The KEY stops being a frontend heap address. It is MGPipeHandle{Slot, Gen}, minted by the
// client's MGPipeSlotAllocator off the frontend object's GetLifetimeId(). A recycled heap
// address cannot reproduce a handle, so the weak_ptr the registry carried per entry purely
// to catch that (its Entry::stateRef, used as an IDENTITY test) stops being an identity
// mechanism, and OwnerEquals / TwinLookupMemo x3 / UnitSamplerLookupMemo's owner compare all
// lose their reason to exist.
// * The lookup stops being a hash probe into an open-addressed map and becomes one bounds
// check plus one array index, so a returned BackendPtr* is NOT invalidated by the next Find
// on the table. That kills the hazard Managers.h documents at length, and with it the
// by-value copy plus second Find that SyncTextureObjectToBackend paid to survive it.
// * Slots are dense per kind, which is what lets the server side (ARCHITECTURE.md 10.1,
// MG_Remote/Server/PipeObjectTables) be an array rather than an object graph.
//
// Death is ANNOUNCED, and that is what lets this table have no garbage collector - the
// deliverable ROADMAP.md:18 spells "GC" in and the one D13 makes a precondition of the switch-
// over. All six re-keyed object classes raise MG_State::GLState::NotifyStateObjectDestroyed()
// from their destructor carrying {kind, lifetimeId, handle}; the backend consumes it in
// Managers.cpp and releases the twin BY THAT HANDLE in every holder of the kind
// (ReleaseTwinByHandle below - the same release the wire's object_death runs on a server), and
// the CLIENT returns the slot after the notice (PipeFill.cpp's NotifyAndFree). So:
// * there is NO draw-path tick, NO creation tick and NO sweep of any kind;
// * a twin, and the driver storage it owns, is freed when the application lets go of the
// object rather than up to 64 creations or 1024 draw ticks later. That is what
// Managers.h's "dead gigabytes" note asked for.
//
// EVERY HOLDER OF THE KIND, not one. Two live tables of one kind is a real configuration - the
// ScopedDirectGLESTextureBindings fixture keeps a by-value copy of the Texture registry for the
// length of a test, and a context reset does the same in reverse. Every table therefore links
// itself into a per-table-type list at construction and out at destruction, and one release
// drops the twin in each holder by handle. (The list is per table TYPE; the kind is the type's
// template parameter, and each of the six kinds has exactly one table type in this backend.)
//
// A destructor that runs after exit() has begun has its notice dropped by InProcessTeardown(),
// and that twin is then a DELIBERATE leak (the process is exiting, the driver reclaims the
// object, and a twin destructor must not call into a driver that may already be unloaded).
//
// P13: THE TABLE IS HANDLE-ONLY. The frontend-keyed half - a GetOrCreate that minted handles
// off a frontend object's lifetime id from inside MG_Backend, the object-keyed Find / HandleOf
// with their lifetime-id memo, the weak per-entry state note and the lifetime-id death walk -
// was monolith glue, unreachable once every family ran the record arm, and is deleted. A handle
// is minted by the CLIENT and arrives in the record; nothing on this side touches the client's
// slot allocator (the link ratchet's P13 exit gate pins that).

// =====================================================================================
// P14 S6 (docs/Disaggregated/design/11-state-ownership.md): THE TWIN TABLE IS PER
// {session, share group}, NOT PER PROCESS.
// =====================================================================================
//
// WHAT WAS WRONG, in one sentence: a twin is a DRIVER object - a GL buffer id, a program, a
// texture, the storage behind them - so it belongs to one native context's object namespace,
// and a table keyed by {slot, gen} ALONE resolves the same handle value to the same twin
// whichever context asked. The frontend gives two contexts that do NOT share a group two
// independent name spaces, so the same {slot, gen} in both is legal and means two different
// objects; one process-wide table made the second context adopt the first's twin (including
// its driver ids, its persistent map and its pooled store). At the same time two contexts of
// ONE group - which must see one set of objects - were served by whichever of them twinned
// first, i.e. by luck rather than by the group the two agree on.
//
// THE KEY IS the same pair the applier files its OBJECT RECORDS under: {session, share
// group}. Same probe, same `0 means this context started its own group` rule (see
// DirectGLES.h's TwinKey and SessionRuntime.cpp's ResolveThreadTwinKey), so a record and the
// twin it describes are always in the same bucket. Session is in the key because a twin
// names a driver id and no driver id crosses a connection - two connections in one process
// are two clients, and nothing may be shared with either from the other.
//
// THE HOLDER LIST STAYS PROCESS-WIDE AND THAT IS NOT A COMPROMISE. A notice is about an
// OBJECT, not about a bucket: ReleaseTwinByHandle must reach
// the by-value copies a fixture or a context reset is holding, whichever bucket they sit in,
// and "which bucket holds it" is exactly the question that produced the two-holder leak the
// list exists to fix. Each SHARED holder of the list is ONE bucket; the walk therefore covers
// every bucket of every table.
//
// THE SAME TABLE OBJECT IS REUSED, NOT REPLACED, and that is what keeps ~200 call sites
// alive: `g_backendTextureObjects.Find(...)` still answers from the bucket the calling thread
// is in, because the object the global names multiplexes on the key at each lookup. A caller
// that must address a bucket OTHER than the calling thread's - the death walks, the
// session-teardown drop - takes Shared() or calls the static entries, which walk buckets;
// and a caller that wants the whole process's view (the teardown, the tests) takes Snapshot().
// FORWARD-DECLARED, because the registry below is DEFINED before the table it holds; the
// members that name the table are defined out of line at the bottom of this header.

// * ONLY Magma's own Track-H bit is checked. Espryt's bit 5 is Espryt's business (a
// DirectVulkan run does not execute one line of DirectGLES' re-key), so
// MOBILEGL_PIPE_PUSH=0x20 must not kill a Magma run, and MOBILEGL_PIPE_PUSH=0x40 must
// not kill an Espryt one.
// * bit 0 (kMGPipeSubsystemRenderState) is NOT Track H and is NOT fatal. It is not a
// memo re-key at all: it decides where the pipeline memo's STATE KEY comes from, and
// a clear bit there simply means the client is not pushing render-state CSOs in this
// run, which GetOrCreatePipeline answers with its own state hash. D14 labels bits 5
// and 6 "Track H" and labels bit 0 nothing of the sort.
// * it is Fatal at STARTUP, once, not on a draw. A per-draw abort inside
// GetOrCreatePipeline turns a configuration mistake into a mid-frame crash and puts a
// branch nobody needs on the hottest path in the backend.
//
// [declared deviation from D14, review v2 minor 2] D14's runtime row reads "false: the

// P7 wave 2 package C, CONTRACT-P7 §3.2 `vertex-layout`: THE ONE STRING BECAME TWO

//
// Every reason here used to return false, and the single caller answered that with
// one P7-marked MagmaWireFatal - an abort, bypassing Session::Fail, invisible
// to the census gate and with no equivalent on the monolith arm at all. But the
// reasons are not one kind of thing:
//
// * `buffer-window` is a statement about the RECORD: an enabled attribute the
// program reads names a slot outside the window set_vertex_buffers published.
// Nothing about the device or the format is involved; the two halves of the
// protocol disagree about what crossed. It stays a named Fatal through the hook
// (see the caller), and it is load-bearing rather than defensive - it is what
// caught the Redmi VAO hash collision fixed in 376c04be.
//
// * every other reason is a statement about what VULKAN CAN EXPRESS on this
// device: a GL type with no VkFormat, a format without
// VK_FORMAT_FEATURE_VERTEX_BUFFER_BIT, a component size we cannot compute, an
// offset sum that does not fit. The monolith arm has had an answer for these
// since it was written, and it is not an abort: mask the attribute out of the
// vertex input state and carry on (the `unsupportedAttribMask |= ...; continue;`
// sites in GetOrCreateVertexInputState above). The draw path then decides,
// loudly and once, whether the masked attribute was one the program actually
// reads. This arm now does exactly that, which is what "same observable as the
// monolith lane" means for this row.
//
// THE COUNT: the contract says "the other six"; there are SEVEN return sites below
// it, because `offset-overflow` was added after the audit's count and is an
// arithmetic guard rather than a shape one. It is masked with the rest: an
// attribute whose base offsets cannot be added is one Vulkan cannot fetch, the
// monolith arm never computes that sum at all, and masking is strictly safer than
// a Fatal for a number no application can reach on purpose. Recorded in
// notes/p7/magma-c.md rather than silently reconciled.
