[Mesa-dev] [PATCH 7/8] android: support creating texture from gralloc buffer

[Mauro Rossi]

Hi all,

another try to merge android swrast patches in mesa 17.1 or mesa-dev
if they are somehow considered useful for android.

Hi Rob,
we are still maintaining these changes to use llvmpipe
they are working and they are useful for testing on VMs and for software
rendering.

May I kindly jask  if the unwanted gralloc dependency was essentially in
 this patch 07/08
"android: support creating texture from gralloc buffer"?

And if that is confirmed, which approaches are applicable here?

1. Reuse some kms-dri specific change implemented in CrOS (? Tomasz did you
neeed to change something in dri/sw winsys ? )

2. Look into openswr corresponding code paths (? I don't know if Tapani may
provide some info for cross reference)

3. Not touching current  AS-IS src/gallium/winsys/sw/dri/dri_sw_winsys.c (?
was this option mentioned by Emil ?)

4. Rewrite only dri/sw winsys parts with buffer allocation provided by
gralloc.gbm (?a kind confirmation by Emil, Rob if this is viable and
acceptable)

I think that some kind of retro compatibility/coexistence with gralloc.drm
is desirable, so I wanted to kindly ask for you feedbacks
and as usual I'm available for building/testing and also to try to patch
some code
to have it working, acceptable and merged.

Mauro
