Hello,

Looking at the sources, I see that you've been adding Vulkan support. What is the current status of Vulkan support in Swiftshader? Is it enough for working with Vulkan API suported in Android Q?
Also, if I want to experiment with Vulkan's support in Swiftshader, what branch should I use -- master or some other branch?

Thank you,
Irena

Vulkan is under development currently, it's in the master branch, but it's not ready to be used for testing yet.

Thank you, Alexis. Do you have an estimate of when it will be ready for testing?

Hi Irena,

You can track our progress here: https://docs.google.com/spreadsheets/d/1RCxbqtKNDG9rVMe_xHMapMBgzOCp24mumab73SbHtfw/edit?usp=sharing

The main missing feature now is texture sampling, but we'll be able to recycle a lot of that from our OpenGL ES 3 implementation so we can get something interesting rendering soon.

Cheers,

Nicolas

Hi Nicolas,

Thank you very much for providing the link to your progress tracking.
vulkan-master graph looks very promising.
Does it show vulkan support status on master branch?

Could you please clarify what are vulkan-master-risky and vulkan-wsi?
Are those branch names? I don't see such branches in the repo.

Regards,
Irena

Hi Irena,

Yes, the graph shows conformance restults for our master branch. The vulkan-master tab actually refers to master folder of the Android dEQP repository that we're using: https://android.googlesource.com/platform/external/deqp/+/refs/heads/master/android/cts/master/ i.e. we're not using tests from older 'desert' versions of Android.

Likewise vulkan-master-risky refers to the tests in the vk-master-risky.txt file. Note that we're actually using a more up-to-date internal repository than the one in AOSP.

I hope that clarifies things. We're now ready to start receiving feedback from users, so if you find any issues not covered by a dEQP test, feel free to file a bug!
