[Mesa-dev] [PATCH v2 3/6] radeonsi:optimizing SET_CONTEXT_REG for shaders VS

[Marek Olšák]

I didn't see any issue when I was testing Tahiti and Hawaii on amdgpu.
radeon is too unstable for a 16-thread piglit, so I never use it.

You can try to set reg_saved = 0 in si_begin_new_gfx_cs. That should
prevent issues with CLEAR_STATE.
