- Reimplements render target views used for sampling
- Optimizes access using an encoded control token
- Adds proper encoding for 24-bit textures (DRGB8 -> ORGB/OBGR)
- Adds proper encoding for ABGR textures (ABGR8 -> ARGB8)
- Silence some compiler warnings as well
- TODO: Real texture views for OGL current method is a hack
- 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
- Export some debug information in the free texture register space components zw
Very useful when analysing renderdoc captures
- Enable shadow comparison on depth as long as compare function is active and texture is uploaded for depth read
Some engines (UE3) read all the components in the shader and use mul/mad with the result
- According to NV_fragment_program spec, registers are zero initialized always
- A program even without writing to these registers will have black (0, 0, 0, 0) output
Confirmed behaviour with MotorStorm games. Their engine uses this quirk to clear color buffers when doing depth replace
Might be an unfixed game bug
- Forces Bitcast of texture data if input format cannot possibly be the
same as the existing texture format
- rsx: Other minor improvements to texture cache :-
- remove obsolete blit engine incompatibility warning. The texture will be re-uploaded if it is indeed incompatible
- Implement warn_once and err_once to avoid spamming the log with systemic errors
- Track mispredicted flushes
- Reswizzle bitcasted texture data to native layout
TODO: Also needs reshuffle according to input remap vector
- 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
- Identify depth textures reaching the gpu via shader_read upload path
- Use correct timestamp counter for opengl
- inline draw_state::test_property because msvc doesnt do it for us
- Fix for texture barriers
- vulkan: Rework texture cache handling of depth surfaces
- Support for scaled depth blit using overlay pass
- Support proper readback of D24S8 in both D32F_S8 and D24U_S8 variants
- Optimize the depth conversion routines with SSE
- vulkan: Replace slow single element copy with std::memcpy
- Check heap status before attempting blit operations
- Bump guard size on upload buffer as well
- Implement flush-always behaviour to partially fix readback from a currently bound fbo
- Without this, only the first read is correct, as more draws are added the results become 'wrong'
- Fixes WCB and cpublit behviour
- Synchronize blit_dst surfaces to avoid data loss when gpu texture scaling is used
- Its still faster in such cases to disable gpu texture scaling but some types cannot be disabled without force cpu blit (e.g framebuffer transfers)
- Memory management tuning
- rsx: on-demand texture cache rescanning for unprotected sections
- rsx: Only framebuffer resources are upscaled
- Do not resize regular blit engine resources
- Lazy initialize readback buffer when using opengl
-- These measures should help minimize vram usage
- Do not assume texture2D when creating new textures
- Flag invalid texture cache if readonly texture is trampled by fbo memory.
Avoids binding a stale handle to the pipeline and is rare enough that it should not hurt performance
- Do not add unused subroutines in shaders unless necessary
-- makes shaders easier to read and disassembled spir-v has less clutter
- glsl: Replace switch block with lookup table
- Use edges of depth range to map clamped stuff
Disable range compression on regular draws vs extended range draws
- Some applications require full 0-1 usage without compromises.
-- TODO: This leaves the extended range z values to fight with regular draws in the .99 - 1.0 range
- The scale offset matrix is fine but on real hardware the z results seem to be independent of near/far clipping distances
-- If depth falls within near/far, clamp depth value to [0,1]
- Force mipmap count to 1 if sampling from an RTV/DSV
- TODO: Better wcb flush detection, it should be better to re-upload the texture after it has been dwnloaded if expected mipmaps are > 1
- Sometimes square renders are done to surfaces with pitch=64 and re-uploaded with swizzle scanning
-- This setup avoids discarding targets if they are square and pitch == 64
- Abort nv406e semaphore acquire if the rsx thread stalls/crashes
- Fix texture size approximation to take mipmaps into account. Fixes some games hanging with WCB
- Avoid unprotecting memory until just before we have to write the data
- Avoids race conditions where the caller thread takes too long to enter the second phase and another thread accesses the "bad" memory
- Reorganize storage hash vs ucode hash
- Scan for actual fragment program start in case leading NOPed code precedes the actual instructions
-- e.g FEAR2 Demo has over 32k of padding before actual program code that messes up hashes
- Discard intentionally invalidated framebuffer resources. These are created after a flush has happened, forcing reupload since contents cannot be guaranteed (strict mode only)
- Fix for blits using vulkan; dont use the copy method if formats do not match, use generic blit instead
- Handle aliased depth + color target by disabling depth writes. This looks to be the correct way
- Add support for generic passes that cannot be done using general imaging operations. Lays the framework for tons of features and effects
- Implement RGBA->D24D8 casting. Sometimes games will split depth texture into RGBA8 then use the new RGBA8 as a depth texture directly
-- This happens alot in ps3 games and I'm not sure why. Its likely the ps3 did not sample fp values with linear filtering so this is a workaround
-- Only implemented for openGL at the moment
-- Requires a workaround for an AMD driver bug
- Fix texture cache blit behaviour when src has AA enabled and dst is a blit dst texture with or without AA
-- This requires handling AA resolve by removing a half downscale on multisampled axes
- Return all ones when a vertex attribute is disabled.
-- Some games forget to enable vertex attributes actually needed by the fs
- texture_cache: Fix internal size calculation for subresources
- vk: Delay dynamic state updates until just about to draw to ensure no flush has discarded the cb state
- Support for raster offsets in surface descriptors (looks to be unused)
- Do not tag disabled render targets when using MRT (pitch = 64)
- Add missing notify_surface_changed() call for openGL
- Use AA mode to predict surface compression. Compression mode is useless without AA activated
- Rewrites most image subresource fetch routines to use the new heuristic
- Fix rsx:🧵:find_tile. FEED000(X) can be substituted for (X) in the code
-- Fixes alot of failures when looking for tiled regions
rsx: Fix antialiased unnormalized coords
- scaling factors are inverse to allow proper coordinates to be computed in fs
- 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

- 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
to flush_all is up to date. Should prevent recursive exceptions
Partially revert Jarves' fix to invalidate cache on tile unbind. This will
need alot more work. Fixes hangs
- This allows for better handling of deferred flushes.
-- There's still no guarantee that cache contents will have changed between the set acquisition and following flush operation
-- Hopefully this is rare enough that it doesnt cause serious issues for now
- vk: Always reopen primary command buffers. They should only be closed in flush_command_queue
- If uploading a texture and there are collisions with protected buffers, do not rebuild the cache
- Perform writes via flush before reprotecting pages that were not trampled
- Only flush no pages once
- Refactor invalidate memory functions into one function
- Add cached object rebuilding functionality to avoid throwing away useful memory on an invalidate

rsx: Fix cpu copy detection
rsx: Validate blit dst surface and dont make assumptions about region blit order
- Also relax restrictions on memory owned by the blit engine if strict rendering is not enabled

- Move structs outside of classes to avoid clutter
rsx: Blit engine improvements
- Always handle blits to and from framebuffers through the GPU
- Handle depth surfaces properly when using GL
- Check for format mismatches when blitting to the surface store [WIP]
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
- Do not set zfunc if alphakill is not enabled. This is because at the moment alphakill requires a different shader to be built
- use glsl loop-unroll friendly comparison; skip vertex input compare if either key requests it
- Minor tweaks to fp key generation
rsx/vk/shaders_cache: Move vp control mask to dynamic state
rsx/vk/gl: adds a shader cache for GL. Also Separates pipeline storage for each backend
rsx: Add more texture state variables to the cache

- Move set_viewport to the uninterruptible block before drawing in case cb is switched before we're ready
- Manage frame contexts separately for easier async frame management
- Avoid wasteful create-destroy cycles when sampling rtts
- 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
