- Improve dirty state tracking affecting program state
- vk: Refactor out transform constants upload into a separate channel to avoid if possible
transform data uploads are quite expensive
- Introduces a gpu program analyser step to examine shader contents before attempting compilation or cache search
- Avoids detecting shader as being different because of unused textures having state changes
- Adds better program size detection for vertex programs
- Improved vertex program decompiler
- Properly support CAL type instructions
- Support jumping over instructions marked with a termination marker with BRA/CAL class opcodes
- Fix SRC checks and abort
- Fix CC register initialization
- NOTE: Even unused SRC registers have to be valid (usually referencing in.POS)
- Formats support is linked to the physical device and by extension the logical device derived from it
It therefore makes no sense to track this as a separate object.
Simplifies parameter passing and template specialization.
Also avoids corner cases with AMD hardware (where D24S8 is not supported)
- vk: Clear dirty textures before copying 'old contents' in case the old data does not fill the new region
- rsx: Properly decode border color - seems to be in BGRA format
- vk: better approximation of border color to better choose between the presets
- vk: Individually clear color images outside render pass and without scissor
- vk: Fix renderpass selection for clear overlay pass
- vk: Include scissor region when emulating clear mask
NOTES:
- vk: Completely avoid using vkClearXXXXimage - its 'broken' on nvidia drivers
Spec is vague about the function so its not an actual bug
ClearAttachment is clearly defined as bypassing bound state which works correctly
- TODO: Implement memory sampling to simulate loading precleared memory if cell used memset to preinitialize the framebuffer
Autoclear depth to 1|255 and color to 0 is hacky!
- 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
Primary:
- Fix SET_SURFACE_CLEAR channel mask - it has been wrong for all these
years! Layout is RGBA not ARGB/BGRA like other registers
Other Fixes:
- vk: Implement subchannel clears using overla pass
- vk: Simplify and clean up state management
- gl: Fix nullptr deref in case of failed subresource copy
- vk/gl: Ignore float buffer clears as hardware seems to do
- Mainly affected are colormasks and read swizzles
NOTES:
- Writes to G write to the second and fourth component (YW)
- Writes to B write to first and third component (XZ)
- This means the actual format layout is BGBG (RGBA) making RG mapping actually GR
- Clear does not seem to have any intended effect on this format (TLOU)
Fixes the following issues on Tales of Vesperia which requires SRM.
- Blacked out scene after the sleeping dog now renders correctly
- Ghosting effect. The ghosting was most noticeable as a delay between the character rendering and the cell shading around the character. This appears to be gone with this change.
- 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
gl/vk: Bump shader cache version
gl/vk: Disable anisotropic override when strict mode enabled as it is proven to alter some games negatively
gl: Clamp buffer view range to not exceed the backing buffer size. Also add assert for the same condition
- ZCULL unit emulation rewritten
- ZCULL reports are now deferred avoiding pipeline stalls
- Minor optimizations; replaced std::mutex with shared_mutex where contention is rare
- Silence unnecessary error message
- Small improvement to out of memory handling for vulkan and slightly bump vertex buffer heap
- 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
- Do not bother rechecking the dirty sampler pool for hits. Its faster to create new sampler than to search the pool
- Reserve some memory on vertex layout struct to reduce reallocation penalty
- Adds support for abstract implementations
- Adds native windowing implementations for WIN32 and X11 as fallbacks
when present support is lacking (headless configs)
- Fix for texture barriers
- vulkan: Rework texture cache handling of depth surfaces
- Support for scaled depth blit using overlay pass
- Support proper readback of D24S8 in both D32F_S8 and D24U_S8 variants
- Optimize the depth conversion routines with SSE
- vulkan: Replace slow single element copy with std::memcpy
- Check heap status before attempting blit operations
- Bump guard size on upload buffer as well
- 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
- vulkan: Do not assume an aux frame context must exist in a well defined state as set in init_buffers() since the request might be external (via overlays path)
- gl: Do not bother waiting for idle before servicing external flip requests
- gl: Queue overlay cleanup requests to ensure only glthread attempts touching the context
- overlays: Do not compute size metrics for invalid/unsupported glyphs
- opengl driver optimization for nvidia. On nvidia glTextureBufferRange performance is horrendous
-- Initialize texture buffer to whole buffer at startup and use absolute offsets to read data instead
-- Over 2x performance in some cases (Resogun, TNT racers)
- gl/vk: Do not flip non-existent display buffers. Fixes spec violation at boot in TNT racers demo
- whitespace fixes for sys_rsx
- The scale offset matrix is fine but on real hardware the z results seem to be independent of near/far clipping distances
-- If depth falls within near/far, clamp depth value to [0,1]
- Always flush the primary queue and wait if not involking readback from rsx thread
-- Should fix some instances of device_lost when using WCB
-- Marked remaining case as TODO
-- TODO: optimize amount of time rsx waits for external threads trying to read
- 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
