swung0x48 7de09a673d [Refactor] (CMakeLists.txt, MG_Backend, MG_Backend/DirectGLES, MG_Backend/DirectVulkan, MG_Remote/Client, MG_Remote/Protocol, MG_Remote/Server, MG_Test/Backend, scripts/data): move BackendObject's EGL bookkeeping into EGLSurfaceRegistry 
- EGLSurfaceRegistry owns the display, the surface records, the active surface, each thread's binding and the one recursive lock; BackendObject holds one and is its hooks, so the EGL virtuals keep their signatures and their defaults
- the backends reach it through EGLRegistry(): lookups return copies, and the steps they compose (adopting an already-bound surface, a window's surfaces, a window's new extent) are named operations instead of writes to protected fields
- WindowBackend and WindowHandle move with it
- BackendObjectEglStateTest only re-points its accessors; the same 235 mutants, carried over, get the same verdicts except three that need a kind-None record, which no call can make, and one that cannot be written against the registry
- comments that cited BackendObject.cpp line numbers name the function

swung0x48 1aa5cf63a6 [Refactor] (MG_Backend, MG_Backend/DirectGLES, MG_Backend/DirectVulkan, MG_Impl, MG_Impl/EGLImpl, MG_Impl/GLImpl, MG_Impl/GLXImpl, MG_Pipe, MG_Remote/Client, MG_Remote/Server, MG_Test/Wire): split the server-only and client-only hooks out of BackendObject 
- ServerHooks and ClientHooks (BackendRoles.h) hold the virtuals that only the server, or only a client of a remote server, calls, with the defaults they had; BackendObject::AsServer and AsClient return them, or null for a backend without the role
- DirectGLES and DirectVulkan implement ServerHooks, BackendObject_Remote implements ClientHooks, and the test doubles that run as a server's backend take the server role
- every call site keeps its answer: where no backend and a backend without the role answered differently, the backend check stays and the role check gives the old default
- ServerLoop::BackendHooks is the server's accessor, asked at each use
- comments that placed the function table in BackendObject.h name BackendFunctions.h

swung0x48 e058a4507a [Perf] (MG_Remote): the apply loop hands its poll's ring head to the drain, so a woken drain does not poll the GPU-fault verdict twice (Espryt rd12 inproc apply thread 1.34 -> 0.78 ms/frame). 2026-10-07 18:21:12 -04:00

swung0x48 f22ae625cb [Fix] (Server): a lost session's window lease is waited for by the fresh session, and a window wait holds no backend turn. 2026-10-03 09:05:54 -04:00
swung0x48 90e63c9e2a [Feature] (EGL+GL): advertise EGL_EXT_create_context_robustness and GL robustness, with per-context reset notification and a pid-targeted device-loss knob. 2026-10-03 04:37:33 -04:00
BZLZHH 8245221755 [Fix] (Remote): name a shared image by extent and format when the kernel gives descriptors one identity 
(st_dev, st_ino) is how an incoming dma-buf descriptor names the image it was
exported from, and it is the only identity the registry had. Some kernels do not
keep those apart: on a 4.14 vendor kernel every descriptor of every image reports
dev 12 ino 10658 with st_size 0, and /proc/self/fdinfo carries nothing else, so
the registry correctly detected the ambiguity and then refused every import -
which is every zero-copy window a compositor ever tries to sample, leaving the
whole stack on the wl_shm fallback.

The identity stays the kernel's to give. When it is ambiguous, the import's own
extent and format select among the live images exported under that identity, in
allocation order and each claimed once, which is the order a producer allocates
and hands them over in. Identify() takes the extent and the fourcc the import
record already carries; nothing else changes.
