[Mesa-dev] [PATCH 23/23] anv: Implement VK_ANDROID_native_buffer
Chad Versace

This implementation is correct (afaict), but takes two shortcuts
regarding the import/export of Android sync fds.
Shortcut 1. When Android calls vkAcquireImageANDROID to import a sync
fd into a VkSemaphore or VkFence, the driver instead simply blocks on
the sync fd, then puts the VkSemaphore or VkFence into the signalled
state. Thanks to implicit sync, this produces correct behavior (with
extra latency overhead, perhaps) despite its ugliness.
Shortcut 2. When Android calls vkQueueSignalReleaseImageANDROID to export
a collection of wait semaphores as a sync fd, the driver instead
submits the semaphores to the queue, then returns sync fd -1, which
informs the caller that no additional synchronization is needed.
Again, thanks to implicit sync, this produces correct behavior (with
extra batch submission overhead) despite its ugliness.
I chose to take the shortcuts instead of properly importing/exporting
the sync fds for two reasons:
Reason 1. I've already tested this patch with dEQP and with demos
apps. It works. I wanted to get the tested patches into the tree now,
and polish the implementation afterwards.
Reason 2. I want to run this on a 3.18 kernel (gasp!). In 3.18, i915
supports neither Android's sync_fence, nor upstream's sync_file, nor
drm_syncobj. Again, I tested these patches on Android with a 3.18
kernel and they work.
I plan to quickly follow-up with patches that remove the shortcuts and
properly import/export the sync fds.
Non-Testing
===========
I did not test at all using the Android.mk buildsystem. I probably
broke it. Please test and review that.
Testing
=======
I tested with 64-bit ARC++ on a Skylake Chromebook and a 3.18 kernel.
The following pass:
