- Fix reading of varying registers in FP
Different registers have different behavior
- Always write to varying registers. If a register is not written to, it is initialized to (0, 0, 0, 1)
- Reimplements two-sided lighting correctly without hacks
- Also bumps shader cache version
- Do not allow offloader to handle its own faults. Serialize them on RSX instead.
This approach introduces a GPU race condition that should be avoided with improved synchronization.
- TODO: Use proper GPU-side synchronization to avoid this situation
- Properly commit orphaned blocks not invalidating existing cache structures
- Do not ignore overwritten objects when commiting as unprotected fbo. Avoids stale references to invalidated surface objects.
- Implements render target data load (aka Read Color Buffer/Read Depth Buffer)
- Refactors vulkan surface barrier to be much cleaner.
- Removes redundant surface barrier invocations after doing a merged load
from surface cache.
- Adds explicit access modes when gathering surfaces from cache.
- Further improve aliased data preservation by unconditionally scanning.
Its is possible for cache aliasing to occur when doing memory split.
- Also sets up for RCB/RDB implementation
vkAcquireNextImageKHR can also return VK_SUBOPTIMAL_KHR and is non-fatal.
However, it's a good idea to still recreate the swap chain later to maintain
optimal presentation paths after temporary occlusion.
- ZCULL queue was updated to one-per-cb but the conditional render sync hint was not updated.
- Do not unconditionally flush the queue unless the upcoming ref is contained in the active CB.
- This avoids spamming queue flush, which frees up resources and improves performance
- Merge viewport raster window and scissor into one clipping region
- Viewport raster clip is different from viewport geometry clipping in
hardware as the latter is configurable separately
- Tagged eventIDs can be used to safely delete resources that are no
longer used
- TODO: Expand gc to collect images as well
- TODO: Fix the texture cache to avoid over-allocating image resources
- Fix a typo in OpenAL
- Fix typo in cellHttp.h
- Unused variables in catch
- Use 64-bit shifts
- Use use_count with shared pointers, unique is depracated and getting removed
- Explicitly cast boolean to int
- Signed/unsigned issues with loop variables
- Fix missing return statement (the code path is unreachable, but compiler wants a return)
- */ ouside of comment
- Fix duplicate layout name
- Do not consume a slot every draw call, instead batch as many draws as possible
- Since renderpasses are dispatched per-draw-clause, keeping occlusion queries outside the renderpasses works fine
- If renderpasses are reorganized, occlusion tasks will have to be reorganized again
- Remove string comparisons from the hot-path!
- Use attribute streaming and push constants to avoid forcing a descriptor block copy every other draw call/pass.
While this isn't so bad on nvidia cards, it makes AMD cards a slideshow.
- When multithreaded RSX is enabled, the vertex cache just lowers performance
- The small cost of upload is paid by the asynchronous thread, allowing RSX to work optimally
- Refactor overlays and resolve passes to support use of push constants instead of relying buffer map/unmap
- Add support for nvidia resolve (NV is the only vendor not supporting shader_stencil_export)
- Removes a lot of wm_event code that was used to perform window management and is no longer needed.
- Significantly simplifies the vulkan code.
- Implements resource management when vulkan window is minimized to allow resources to be freed.
- Just use a semaphore and let the driver handle it instead of manual framepacing.
We lose framepace control but drivers have matured in the past few years so it should work fine.
- Ensures the current renderpass matches the image properties even when a cyclic reference is detected
- Solves SDK debug output error spam due to mismatching layouts and renderpasses
- Add double-buffered descriptor pools to avoid use-after-free situations
- Make descriptor pools more configurable
- Also adds in a hack to allow renderdoc to capture properly
- Use a simple queue to avoid redundant checks over all the contexts
- Poll queue if RSX pipe is idle
- Only check the queue when the frame context is dirty (after a queue operation)
- Reset descriptors at the start of the frame context to avoid having to synchronize mid-frame
- Fully synchronize if a descriptor reset is required mid-frame (spec compliance; also fixes flickering verts on some hardware)
- Transition attachments to LAYOUT_GENERAL in case of a feedback loop
- Fixes appearance of garbage along polygon edges in some
post-processing passes.
- Also reverse this transition when rendering goes back to normal
