* gallium: Change PIPE_CAP_TGSI_FS_FBFETCH bool to PIPE_CAP_FBFETCH countKenneth Graunke2019-05-231-1/+1
| | | | | | | | | | | | | | TGSI's FBFETCH instruction currently only supports reading from a single render target, but NIR intrinsics can support multiple render targets. radeonsi can only support fetching from RT 0, but other drivers may be able to support fetching from any render target. To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?" to an integer number of render targets which can be fetched.

The buffer always reports format PIPE_FORMAT_R8_UNORM so with this patch only one component would be supported. The original issue is still relevant, but the fix should be different.

* gallium: Add PIPE_BARRIER_UPDATE_BUFFER and UPDATE_TEXTURE bits.Kenneth Graunke2019-03-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glMemoryBarrier() function makes shader memory stores ordered with respect to things specified by the given bits. Until now, st/mesa has ignored GL_TEXTURE_UPDATE_BARRIER_BIT and GL_BUFFER_UPDATE_BARRIER_BIT, saying that drivers should implicitly perform the needed flushing. This seems like a pretty big assumption to make. Instead, this commit opts to translate them to new PIPE_BARRIER bits, and adjusts existing drivers to continue ignoring them (preserving the current behavior). The i965 driver performs actions on these memory barriers. Shader memory stores go through a "data cache" which is separate from the render cache and other read caches (like the texture cache). All memory barriers need to flush the data cache (to ensure shader memory stores are visible), and possibly invalidate read caches (to ensure stale data is no longer visible). The driver implicitly flushes for most caches, but not for data cache, since ARB_shader_image_load_store introduced MemoryBarrier() precisely to order these explicitly. I would like to follow i965's approach in iris, flushing the data cache on any MemoryBarrier() call, so I need st/mesa to actually call the pipe->memory_barrier() callback. Fixes KHR-GL45.shader_image_load_store.advanced-sync-textureUpdate and Piglit's spec/arb_shader_image_load_store/host-mem-barrier on the iris driver. Roland said this looks reasonable to him.
