Gregg Tavares 968041b5 2022-08-19T12:11:23 Metal: Optimized BufferSubData per device Adds a staging buffer path which means there are 4 paths for bufferSubData. 1. direct copy * get a pointer to the buffer * copy the new data to the buffer * if the buffer is managed, tell metal which part was updated 2. use a shadow copy * copy the data to a shadow copy * copy the entire shadow to a new buffer * start using the new buffer 3. use a new buffer * get a new buffer (or unused) * put the new data in the new buffer * blit any unchanged data from the old buffer to the new buffer * start using the new buffer 4. use a staging buffer * get a staging buffer * put the new data in the staging buffer * blit from the staging buffer to the existing buffer. Further, there are 3 types of memory storage modes. Managed, Staged, Private. Based on the GPU type different storage modes and different paths in different sitatutions are more performant. So, add feature flags to select paths by GPU.

Geoff Lang 70e5e90f 2022-09-23T13:17:34 Metal: Avoid locking IOSurfaces in glReadPixels on AMD. The AMD driver tends to crash when locking IOSurfaces. Avoid this by using the copyIOSurfaceToNonIOSurfaceForReadOptimization feature to do a texture-texture copy before reading back data to the CPU. This is a *speculative* fix due to seeing crashes in the ClientLockIOSurface function in the AMD driver.

Geoff Lang 2aa52da7 2022-09-23T13:15:44 Metal: Upload IOSurface data with staging buffers on AMD Crashes have been seen in the AMD driver when locking IOSurfaces. Avoid this by always using a staging buffer and doing a GPU-GPU copy for uploading client side data to IOSurfaces.

Gregg Tavares 94320a83 2022-05-27T17:41:29 Metal: Validate total bits used in color attachments Metal has 2 limits for color attachments. 1 the number of attachments supported. 2 the total number of bits it can write per pixel. So for example Apple4 through Apple8 GPUs can have 8 attachments but only 512bits of output. That means you can attach 8 RGBA8 textures (256bits), but you can't attach 8 RGBA32UI textures (1024bits). If there are too many bits then return FRAMEBUFFER_UNSUPPORTED from checkFramebufferStatus and INVALID_FRAMEBUFFER_OPERATION from draws Bug: angleproject:7280 Change-Id: I935aebad4d57664f59a60be20a927d6b69afb4ff Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3674322 Reviewed-by: Kenneth Russell <kbr@chromium.org> Commit-Queue: Gregg Tavares <gman@chromium.org>
Gregg Tavares 8a0351a5 2022-05-26T14:29:21 Metal:Dynamically choose max draw buffers. The code was hard coded to 4 which is lower than OpenGL's 8. This implementation keeps a hard coded array of size 8 in rx::mtl::RenderPassDesc and rx::mtl::RenderPipelineOutputDesc but only uses up to the display's limit.
