RegisterFile zeroes the whole register file at construction, but a real
console comes up with non-zero values in several of the context
registers. If a game reads one of those before writing it, it gets 0
under emulation and the real default on hardware.
I read the reset values off a retail console (read-only) and checked
them against the AMD R6xx register reference and the r600g defaults in
Mesa, which set the same registers to the same values at context init.
Where the hardware read matches the driver default it's a genuine
power-on default, not leftover runtime state.
Left the tessellation levels out on purpose: they reset to 1.0f too, but
the backends do register + 1.0f, so seeding them here would change the
effective reset factor. That needs its own change.
Thanks to latest change there is no need to use hardcoded nanosleep, so we can go back to previous stuff.
Hopefully it will fix some random issues with audio introduced lately
Integer num_format fetches now get their scale CPU-side instead of trying to guess in the shader. This is authoritative; no cvar. Both translators now use texture_integer_scale_bits after signs/gamma and before exponent bias. This alone fixes black screens and a bunch of rendering bugs across at least several dozen titles.
This new information lives in the updated FormatInfo table, including fixed component widths.
Resolve also has two new fixes.
8_8_8_8_GAMMA EDRAM sources can now decode through the PWL curve while still in linear space, before MSAA resolve or format conversion, then re-encoded for gamma destinations. This is also now default enabled via gamma_decode_pwl_resolve and has improved blowout in at least 4 titles, with no obvious regressions thus far.
Full resolve can also now pack fixed destinations according to copy_dest_number.
Check shared memory validity before marking textures up to date and installing watches. If the backing range was invalidated, leave the texture outdated so it can be reloaded later.
Use new archive input to rework artifacts.
Add runs-on and llvm_version inputs and ubuntu_base output to Lint so it can be passed to the Linux job.
Remove broken config input.
Upgrade Windows to VS2026.
Replace the x64 STVL/STVR lowering with explicit byte stores that preserve the
guest-visible vector byte order.
The previous vector shuffle/blend path could write incorrect bytes for partial
vector stores, which broke optimized guest memcpy implementations using
stvlx/stvrx for unaligned heads and tails. In 4156081C this corrupted skinned
model render command data and eventually caused render-thread crashes.
Add regression coverage for StoreVectorLeft/StoreVectorRight across common
unaligned offsets, plus a memcpy-head style case matching the affected guest
instruction pattern.
Implements EVENT_WRITE_ZPD handling across shared CommandProcessor, D3D12, and Vulkan backends.
This adds a shared report lifecycle. Reports can span submissions/render passes, split into multiple segments, and asynchronously retire. Reports can also survive same-slot reuse, which is critical for titles that aggressively recycle against a small pool.
RTV/FBO use their respective host occlusion queries, whereas ROV/FSI use counter buffers instead, with shader helpers that are called from the translated PS, accumulating surviving MSAA sample coverage into active slots. Regardless of approach, results are copied to small, dedicated readbacks and fed through shared retirement.
Fast mode writes speculative values and patches in resolved results later. Strict mode waits for real results with a small retire backstop so it doesn't spin forever when a report gets weird. Fake mode's fundamentals are unchanged, it just now uses XenosZPDReport memory helpers like all the modes do.
Also adds optional sample count saturation for instances when attenuation isn't a one-for-one with real hardware, an optional alternate fast behavior that preserves cached zeroes (that can improve flare-heavy titles but might regress occlusion culling), and normalization for upscaling.
QueryBatch is still unsupported other than a fake path that's enabled when a range is set via cvar.
