meta: Store precompiled msaa shaders for all supported sample counts
Currently, BLIT_MSAA_SHADER_2D_MULTISAMPLE_RESOLVE* and BLIT_MSAA_SHADER_2D_MULTISAMPLE_ARRAY_RESOLVE* shaders in setup_glsl_msaa_blit_shader() are not recompiled when the source buffer sample count changes. For example, implementation continued using a 4X msaa shader, even if source buffer changes from 4X msaa to 8x msaa. It causes incorrect rendering. This patch adds new enums in blit_msaa_shader, one for each supported sample count, and uses them to store msaa shaders. Fixes following piglit tests on Broadwell: ext_framebuffer_multisample-accuracy all_samples color ext_framebuffer_multisample-accuracy all_samples depth_draw ext_framebuffer_multisample-accuracy all_samples depth_resolve ext_framebuffer_multisample-accuracy all_samples stencil_draw ext_framebuffer_multisample-accuracy all_samples stencil_resolve ext_framebuffer_multisample-formats all_samples Signed-off-by: Anuj Phogat <[email protected]> Reviewed-by: Jason Ekstarnd <[email protected]>
