Perhaps worth revisiting. Given we've failed to progress at all since
then may change opinions some. We already have to handle multiple
opens share the same pipe_screen, so I don't think reusing the fd buys
us anything.
Maybe we're close to the point of removing the flink name support too.
The android-x86 folks have been working to get dma-bufs working.
Chih-Wei, any comments on this?
Ah! Sorry. I didn't catch or understand the details.
Did you mean the attempts to use drm_hwcomposer
in android-x86?
My understanding so far is most x86 GPUs won't work
except some very limited models.
It's due to kernel driver issues which may never be solved.
So we can't drop the flink name support.
Please correct me if I am wrong.
Could you elaborate a bit more on those GPUs that won't work and
corresponding driver issues? We're running cros_gralloc on Intel and
AMD GPUs, with DMA-buf and render-node only setup and we haven't seen
any problems.
Hi Tomasz,
I remember (in our previous discussion) you said
CrOS uses your own hwcomposer (proprietary?) so
the story may be different.
What we have tried is gbm_gralloc + drm_hwcomposer
and I reported the issues here:
https://lists.freedesktop.org/archives/dri-devel/2017-September/153580.html
I took the liberty of moving you nouveau issue into the drm_hwc gitlab
bugtracker.
https://gitlab.freedesktop.org/drm-hwcomposer/drm-hwcomposer/issues/1
Sorry I didn't make more tests recently.
I CC Mauro to comment. He should have made more tests
with newer kernel and mesa.
