This series adds radeonsi support for GL_EXT_semaphore. GL_EXT_semaphore is used by steam's vrclient to synchronize access to shared surfaces (vulkan <-> gl interop). It allows our gl vrclients to enqueue their framebuffer surface without waiting for a glFinish().
If anyone has any suggestions on improvements for the implicit flush added in patch 9 please let me know. Either a way to remove it, or a way to move it to a codepath that is a bit more specific to radeonsi. Test results for this series (pretty alpha quality auto testing): https://lostgoat.me/gpuci/jenkins/blue/organizations/jenkins/amdgpu-reviews/detail/amdgpu-reviews/184/pipeline Test results for each individual patch can also be found here (see 'Related Changes' section): https://gerrit.lostgoat.me/#/c/454/ And here is a baseline for test results for comparison: https://lostgoat.me/gpuci/jenkins/blue/organizations/jenkins/amdgpu-master/detail/amdgpu-master/1269/tests Tests include Vulkan CTS and piglit on Kaveri and Polaris 10. I just kicked off the tests, so they might still show in a queued/in progress state for a few hours. Hopefully my ryzen server and my test slaves survive the unsupervised effort (*fingers crossed it doesn't catch fire while I sleep*).
