- Some applications (e.g Backbreaker) use an evil hack to resolve MSAA.
The application respecifies a formerly AA region as a region with no AA then performs a framebuffer feedback lookup.
The old memory keeps AA during read, but writes back to itself with AA resolved.
This is evil on several levels but it just happens to work on PS3
- Improve dirty state tracking affecting program state
- vk: Refactor out transform constants upload into a separate channel to avoid if possible
transform data uploads are quite expensive
- Separate TXB from TXL: They are completely different!
- Properly perform TMU emulation in the fragment shader. Implemens SRGB conversion and alphakill at the moment
- Properly perform ROP emulation in the fragment shader. Implements FRAMEBUFFER_SRGB. While support on the chip looks to be incomplete (and wierd), it does work
- Document some more bits in SHADER_CONTROL register
- ZCULL unit emulation rewritten
- ZCULL reports are now deferred avoiding pipeline stalls
- Minor optimizations; replaced std::mutex with shared_mutex where contention is rare
- Silence unnecessary error message
- Small improvement to out of memory handling for vulkan and slightly bump vertex buffer heap
According to the NV_fragment_program spec, its not feasible to have 16-bit depth wries
NOTE: NV_fragement_program precedes NV_fragment_program2 which is very
close to what RSX consumes. It is hardware from that era afterall
- A new step is added between decompilation and pipeline object creation allowing for properties to be updated based on shader contents
- Allos masking off attachment writes that are unmodified in the shader
- Reimplement fragment program fetch and rewrite texture upload mechanism
-- All of these steps should only be done at most once per draw call
-- Eliminates continously checking the surface store for overlapping addresses as well
addenda - critical fixes
- gl: Bind TIU before starting texture operations as they will affect the currently bound texture
- vk: Reuse sampler objects if possible
- rsx: Support for depth resampling for depth textures obtained via blit engine
vk/rsx: Minor fixes
- Fix accidental imageview dereference when using WCB if texture memory occupies FB memory
- Invalidate dirty framebuffers (strict mode only)
- Normalize line endings because VS is dumb
- Emulate primitive restart in software whenever we get the chance
- Ensure PRIMITIVE_RESTART is never active when LIST topologies are active
- Reimplement TRIANGLE_FAN, POLYGON and QUAD expansion
- This communication is important in communicating window events. Helps properly synchronize swapchain management on vulkan and stops nvidia crashing
- Do not block the message queue lest the driver detect window as not responding
- Make each frame context own its own memory
- Fix GPU blit
- Fix image layout transitions in flip
vk: Improve frame-local memory usage tracking to prevent overwrites
- Also slightly bumps VRAM requirements for stream buffers to help with running out of storage
- Fixes flickering and missing graphics in some cases. Flickering is still there and needs more work
vk: Up vertex attribute heap size and increase the guard size on it
vulkan: Reorganize memory management
vulkan: blit cleanup
vulkan: blit engine improvements
- Override existing image mapping when conflicts detected
- Allow blitting of depth/stencil surfaces
Fix rsx offscreen-render-to-display-buffer-blit surface reads
- Also, properly scale display output height if reading from compressed tile
gl: Fix broken dst height computation
- The extra padding is only there to force power-of-2 sizes and isnt used
gl: Ignore compression scaling if output is rendered to in a renderpass
rsx/gl/vk: Cleanup for GPU texture scaling. Initial impl [WIP]
- TODO: Refactor more shared code into RSX/common
- QUAD_STRIP evaluates to TRIANGLE_STRIP in memory. The memory layout is identical.
- The only difference between the two modes would be the primitive_ID but that doesnt matter on RSX
- Its worth noting that results will be different between the two modes if input vertices are non-coplanar for every set of N verts
- Significant gains from greatly reduced CPU work
- Also reorders command submission in end() to improve throughput
- Refactors most of the vertex buffer handling
- All vertex processing is moved GPU side
* Fix always-true conditions in sceNp module
* gl_render_targets: useless check on unsigned variable, possible bug
* fixed UB in crypto utility functions
* copy-paste error in vk::init_default_resources
* pass strings by const ref
* Dont copy vectors. Make sure copies are not needed because functions are used in a multi-threaded context.
* Rework vertex attribute binding for vulkan. Allows always providing a buffer view to the pipeline even if the game has the attribute disabled as long as it is consumed by the vertex shader.
- Improvements to framebuffer usage; Avoid creating new resources every frame
- Handle null fragment program properly
- Collect vertex upload statistics
- vk: Pre-initialize 'unused' varying registers in the vertex shader in case it gets matched with a fs that consumes it
-- Fixes a crash about fog_c not being declared
gl/dx12/vk: Handle null fragment program
- cleanup - use yield semantic instead of sleep(0) as yield is more cross-platform
-- sleep(0) is a windows specific scheduler hint
