[Aggregate issue]: Pending GPU backend work

[raphaelthegreat]

Mostly acts as a checklist on future work so it's not forgotten

Command processor

• Replace coroutines with a manual stack frame management for easier debugging
• Rewrite graphics and CE submissions to use primary ring and IBs
• Rewrite compute submissions to use read/write pointers instead of range list
• Host gpu sync by writing labels from host GPU instead of at parsing time

Shader recompiler

• Implement MBCNT properly without heuristics
• SGPR/VGPR/VCC type tracking (scalar or thread-bit)
• IMAGE_STORE_MIP on NVIDIA
• Ordered appends
• Implement LEGACY instruction variant NaN/Inf behaviors
• Implement proper NEG/ABS modifiers on integer instructions
• Support variable vector and bit sizes in IR instructions for de-duplication purposes
• Min/Max blending factor emulation
• Blending emulation with incompatible COMP_SWAP setting
• Bindless buffers and images

GPU Memory

• Allocate vulkan device memory according to guest memory type
• Use sparse resident buffer for guest GPU address space
• (Linux) Use VK_EXT_map_memory_placed to directly map host GPU memory to guest and bypass memory tracker
• (Windows) Rework memory tracker and its locking to improve performance for large ranges

Texture cache

• Implement per-subresource image state tracking
• Support partial overlap handling and resolution
• Test and implement PRT tiling modes

Reason

Make stuff go brrr

Maybe re-write texture_cache.cpp for GOW3 brightness and textures too glitches

[raphaelthegreat]

That whole section is the rewrite

[itPost-PlcBNN-ship-it]

So it is included? I mean also gow3
