- 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
- For some surfaces, dimensions are passed via the log2 bits rather than surface pitch
-- This is similar to the setup for nv406e and probably means the surfaces are padded and swizzled
- 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
- 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
- Zeta pitch is ignored by real HW for some reason
- Monitor ptch value changes as well since they may affect disabled surfaces
- TODO: Verify if MRT pitch is really taken into consideration
- 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
- 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
- Refactor invalidate memory functions into one function
- Add cached object rebuilding functionality to avoid throwing away useful memory on an invalidate
- Added debug monitoring of texture unit VRAM usage
gl/vk/rsx: Refactoring; unify texture cache code
gl: Fixups
- Removes rsx::gl::texture class and leave gl::texture intact
- Simplify texture create and upload mechanisms
- Re-enable texture uploads with the new texture cache mechanism
rsx: texture cache - check if bit region fits into dst texture before attempting to copy
gl/vk: Cleanup
- Set initial texture layout to DST_OPTIMAL since it has no data in it anyway at the start
- Move structs outside of classes to avoid clutter
- vk: Do not select first available format when choosing a swapchain format
- gl/vk: Ignore rendering zero sized framebuffers/scissors
- fp: Re-enable range clamp on fp16 registers; fix fx12 clamping [-2, 2]
