Fixes VRAM leaks and incorrect destruction of resources, which could
lead to drivers crashes.
Additionally, lock_memory_region is now able to flush superseded
sections. However, due to the potential performance impact of this
for little gain, a new debug setting ("Strict Flushing") has been
added to config.yaml
- Orders flushing to preserve memory at all cost
- Avoids false positive where flushing overlapping sections can falsely invalidate another with head/tail test
- Forcefully downloads and reuploads data from the CPU in case of unexpected overlaps
- Properly detect correct size of newly created blit targets
- Remember to clear any existing views when changing the default component map!
- Retag resources reprotected under flush_always rules
- Properly check for blit resource fitting taking into account format
mismatch, pitch mismatch and typeless transfers
- Avoid re-locking memory if there is no reason to do so (no draws issued)
- Actively bound regions should always get written to the backing cache
- Forcefully read memory during download if writes to the target have occured since last sync event
- Removes the old depth scaling using an overlay.
It was never going to work properly due to per-pixel stencil writes being unavailable
- TODO: Preserve stencil buffer during ARGB8->D32S8 shader conversion pass
- 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
1. rsx: Rework section synchronization using the new memory mirrors
2. rsx: Tweaks
- Simplify peeking into the current rsx::thread instance.
Use a simple rsx::get_current_renderer instead of asking fxm for the same
- Fix global rsx super memory shm block management
3. rsx: Improve memory validation. test_framebuffer() and
tag_framebuffer() are simplified due to mirror support
4. rsx: Only write back confirmed memory range to avoid overapproximation errors in blit engine
5. rsx: Explicitly mark clobbered flushable sections as dirty to have them
removed
6. rsx: Cumulative fixes
- Reimplement rsx::buffered_section management routines
- blit engine subsections are not hit-tested against confirmed/committed memory range
Not all applications are 'honest' about region bounds, making the real cpu range useless for blit ops
- Readback does not work at all with float textures on AMD openGL
Driver throws a bogus OUT_OF_MEMORY error regardless of amount of VRAM and system RAM available
- gl/vk: Fix subresource copy/blit
- gl/vk: Fix default_component_map reading
- vk: Reimplement cell readback path and improve software channel decoder
- Properly name the subresource layout field - its in blocks not bytes!
- Implement d24s8 upload from memory correctly
- Do not ignore DEPTH_FLOAT textures - they are depth textures and abide by the depth compare rules
- NOTE: Redirection of 16-bit textures is not implemented yet
- Ignore unlocked blit sections [TODO]
- Do not attempt blit on hw if bytesize is unsupported
- gl: Implement typeless memory transfers
Uses pbo to handle type-agnostic memory transfer
- 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
- 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
- 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
- Implement low bit decode override flags for 2-component textures
- Properly implement alot of texture remaps according to the autotest results
rsx: Do not unnecessarily shuffle WZYX->RGBA unless we have proof
- From looking at format swizzles, this is incorrect
- 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

- 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
- 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
