- eglSwapBuffersWithDamageEXT is an extension entry point that Android's
framework libEGL does not export through dlsym; requiring it was a
bring-up FATAL on TB321FU. Resolve EXT, fall back to the KHR spelling
(same function, interchangeable signature), then to plain
eglSwapBuffers (a zero-rectangle damage call is defined to be exactly
that). The GLES dlsym fallback gains a self-reference guard for
MobileGL installed under a GLES soname, where dlsym would otherwise
hand the backend the frontend's own entry points and recurse forever.
- NormalizePixelFormat maps GL_STENCIL_INDEX8/GL_STENCIL_INDEX to
GL_STENCIL_INDEX/GL_UNSIGNED_BYTE instead of falling through to
RGBA/UBYTE, which no driver can pair with stencil-only storage.
- Tests pin the EXT->KHR->none preference order and the stencil pair.
- The anland handoff is rewritten to the post-P14 landed state: device
evidence (win-smoke green screen, Konsole on screen, eglinfo/glxinfo),
the remote-only recovery procedure, and the known gaps (Plasma session
bring-up, cursor scale, the no-CPU-blit requirement, resize/surface
loss, AVC audit).
The document still described the state before the state-ownership work
landed: it called the unified server design unfinished, listed the
KernelSU grant as unsolved, said the directory bind had not taken effect,
and presented MobileGLAppsService plus the per-app fork worker as pending
drafts. None of that is true now.
Rewritten against the current tree and the device:
- header: architecture landed per the user's correction, acceptance still
open; the rejected fork-worker/AppsService path is removed and the
unified server lives in the MobileGL library (design 11-state-ownership,
commits d52c031c / 4ed1c9ce / 5c6399e2 / ff212061 / 5a0f13fd, plus the
landed 6fb880cd / ebc552a0 that used to be listed as uncommitted)
- MobileGL: HEAD moved to 5a0f13fd; the state-ownership section now records
what S1-S6 landed and the debts that remain (process-level unit shadows,
g_backendContextGeneration, per-record ContextSlot, the glIsBuffer probe,
the window half of pbuffer->window)
- anland: 2ffa1f5 and 33e496c pushed; the draft inventory is now a landed
inventory plus the three uncommitted KWin-acceptance fixes
- device: KernelSU grant resolved (reinstall changed the uid to 10270), the
clone restarted with the directory bind effective, the 5a0f13fd APK
serving @anland-mobilegl with six completed client sessions, and the
client library installed with a stale build stamp
- new: concurrency warning (parallel sessions have overwritten the dist and
the source tar), the current desktop-session.service failure state, and a
rewritten continuation order
Verified: doc citations resolve (scripts/check_doc_citations.py), device
facts checked against HA27Q3LQ at refresh time.
