Future integration with minigbm require this library in a Soong Blueprint format. Starting from Android S 'libgbm' module name is occupied by minigbm and used by other ChromeOS components. Using 'libgbm_mesa' name was suggested by Google instead. Signed-off-by: Roman Stratiienko <[email protected]>

Commit 17e62a3 made _mesa_make_current begin calling ctx->Driver.Flush() in more cases, including when called during context destruction, after _mesa_free_context_data has set ctx->DrawBuffer to NULL. i965's flush hook wasn't prepared for this, and assumed that ctx->DrawBuffer was non-NULL. This led to a crash with the following backtrace: #0 0x00007ffff5bf97b5 in _mesa_is_winsys_fbo (fb=0x0) at ../../src/mesa/main/fbobject.h:52 android-rpi#1 0x00007ffff5bfa359 in brw_flush_front (ctx=0x5555555a4110) at ../../src/mesa/drivers/dri/i965/brw_context.c:242 android-rpi#2 0x00007ffff5bfa587 in brw_glFlush (ctx=0x5555555a4110, gallium_flush_flags=0) at ../../src/mesa/drivers/dri/i965/brw_context.c:301 android-rpi#3 0x00007ffff5d46b2b in _mesa_make_current (newCtx=0x0, drawBuffer=0x0, readBuffer=0x0) at ../../src/mesa/main/context.c:1616 #4 0x00007ffff5d46484 in _mesa_free_context_data (ctx=0x5555555a4110, destroy_debug_output=true) at ../../src/mesa/main/context.c:1309 #5 0x00007ffff5bfcb59 in brw_destroy_context (driContextPriv=0x555555590260) at ../../src/mesa/drivers/dri/i965/brw_context.c:1301 There is really no point in worrying about front buffer flushing during the context's destruction when we've already discarded the drawbuffer, so just add a NULL check in brw_flush_front and skip that work.

This change requires the %destructor directive which is supported
by bison or yacc, yacc needs to be compiled with the back-tracking

Indeed, the function nir_to_tgsi() returns an ureg_get_tokens() allocated
object which is assigned locally. The ureg_get_tokens() allocated object
should be freed.
For instance, this issue is triggered with a llvm enabled lima,
"piglit/bin/gl-1.0-rendermode-feedback -auto -fbo":

Huge thanks to Tapani Pälli for debugging this issue, figuring out
what was going wrong, proposing fixes, and walking me through where
things were going off the rails.
BLORP always disables tessellation and geometry shaders. Our handling
tried to look at ice->shaders.uncompiled[] to determine whether the next
draw needed those shaders. If not, we can leave BLORP's residual state
that disabled those stages in place, and skip looking at it.
Unfortunately, predicting the future is a bit fraught, in part due to
the uncompiled[] and prog[] arrays being slightly out of sync at times.
Consider the following case:
1. Draw with tessellation shaders in place
=> uncompiled[TES] and prog[TES] will both point at valid shaders.
2. Gallium calls pipe->bind_tes_state(NULL).
=> This makes uncompiled[TES] point at NULL, and flags
IRIS_STAGE_DIRTY_UNCOMPILED_TES.
Because iris_update_compiled_shaders() hasn't happened yet,
uncompiled[TES] is NULL but prog[TES] has the stale TES from
the previous draw still.
3. BLORP operations happen
=> BLORP sees uncompiled[TES] == NULL and decides that tessellation
is off for the upcoming draws. So it skips flagging tess state.
4. Gallium calls pipe->bind_tes_state(shader from step android-rpi#1).
=> uncompiled[TES] points at the original shader.
IRIS_STAGE_DIRTY_UNCOMPILED_TES gets flagged again.
5. Draw again
=> This calls iris_update_compiled_shaders(), which sees that
a TES is bound, and calls iris_update_compiled_tes(). But
because the same shader was bound as before, the program it
comes up with is identical to the one already bound at
ice->shaders.prog[TES]. So, it thinks it doesn't have to
flag any tessellation state dirty because it was already
set up for the last draw.
This random unbind and rebind between draws leads to a situation
where, at step android-rpi#3, BLORP thinks it can skip flagging tessellation
state (nothing is bound), and at step #5, normal state handling
thinks it can skip flagging tessellation state (nothing changed
since last time). So nobody does, and things break.
This unbind appears to be happening when st_release_variants()
decides it wants to free some shaders. Then a rebind happens to
put back the actual shader for the draw. So, it's not theoretical.
To fix this, we change BLORP to look at ice->shaders.prog[] rather
than uncompiled[]. This is equivalent to thinking about the previous
draw, rather than the next. If the last draw had tessellation off,
then BLORP's disabling was a no-op, and the GPU is still in the same
state as the previous draw. This is more reliable than predicting
the future.
