tu: Expose reconverge related extensions
What does this MR do and why?
I tried exposing VK_KHR_shader_subgroup_uniform_control_flow
and VK_KHR_shader_maximal_reconvergence
and on newer CTS version they all pass for me on a619 with kgsl. However, running an older CTS like 1.3.8.0 dEQP-VK.reconvergence.*
tests all fail with Fail (Subgroup size greater than 64 not handled. at vktReconvergenceTests.cpp:1632)
so I'm not sure if we can just advertise them as it is.
I saw a TODO for moving threadsize_base
and max_waves
to fd_dev_info
, so I decided to tackle it. Nevertheless, I am uncertain about the practicality of moving max_waves
, as it currently appears that we would simply be setting it to 16 a couple dozen times.
