- Use proper time checking; depending on what is being done one 'tick' can
be almost a millisecond long or several nanoseconds
- Avoid spamming the system timer unless necessary
- A possible deadlock is still present if rsx is trying to get a super_ptr whilst the vm lock holder is in an access violation
This patch makes this scenario very unlikely since each block need only be touched once
- Implement forced reading when calling update method to sync partial lists
- Defer conditional render evaluation and use a read barrier to avoid extra work
- Fix HLE gcm library when binding tiles & zcull RAM
- Do not do a full sync on a texture read barrier
- Avoid calling zcull sync in FIFO spin wait
- Do not flush memory to cache from the renderer side; this method is now obsolete
- Defer compilation process to worker threads
- vulkan: Fixup for graphics_pipeline_state.
Never use struct assignment operator on vk** structs due to padding after sType member (4 bytes)
- Adds proper support for vertex textures, including dimensions other than 2D textures
- Minor analyser fixup, removes spurious 'analyser failed' errors
- Minor optimizations for program state tracking
- Adds dead code elimination
- Fix absolute branch target addresses to take base address into account
- Patch branch targets relative to base address to improve hash matching
- Bumps shader cache version
- Enables shader logging option to write out vertex program binary,
helpful when debugging problems.
- 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
- The benefits of FIFO optimizations are huge in some cases.
The optimizations also do not break any tested applications so no need to disable with strict mode
- A debug option is provided to disable this behaviour for testing
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
- Properly identify puller spin primitives
- Add a small wake delay after exiting a spin delay. Fixes desynchronization
It seems real hw has a small delay between cell edits to commandbuffer memory at the GET address and the changes becoming visible to the DMA puller
Simulated with a short busy_wait, large values will improve sync but degrade performance
