- 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
- 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
- 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
- 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
- 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
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
