- The bytes in these values are based on the format according to hw tests
- G8B8 is unaffected as the first two bytes are already G8B8 for A8R8G8B8 standard layout (BGRA)
- A8B8G8R8 and its derivatives have words 0 and 2 exchanged.
- The alpha ref register is compared directly to the ROP output register in realhw
- alpha ref content must match bit-width of ROP register, which means fp16 values are possible
- Avoids a situation where a game configures output correctly but gets back bogus information later when querying.
- Should fix games being broken at some resolutions but not others.
Round-to-nearest integral based division, optimized for unsigned integral.
Used in sceNpTrophyGetGameProgress.
Do not allow signed values for aligned_div(), align().
subresource_layout::dim_in_texel
- These two are not always linked when working with compressed textures.
The actual texels extend past the actual size of the image if the size
is not aligned. e.g if height is 1, the real height is 4, but its not
possible to determine this from the aligned size. It could be 1, 2, 3 or
4 for example.
- Fixes image out-of-bounds writes when uploading from CPU
This lowers the relative cost of this function from ~2.25% to ~1.80% on
gcc 9 which I found quite surprising, some of it probably gets inlined
better in the callers, but I haven’t been able to isolate which parts.
- Calculate exact sizes when doing hit tests to avoid false negatives
- Defer page checking until actually require to do memory setup
- Introduce align2 helper to do non-pow2 alignments
Prefer vm::ptr<>::ptr over vm::get_addr.
Prefer vm::_ptr/base over vm::g_base_addr with offset.
Added methods atomic_t<>::bts and atomic_t<>::btr .
Removed obsolute rsx:🧵:Read/WriteIO32 methods.
Removed wrong check in semaphore_release.
Added handling for PUTRx commands for RawSPU MFC proxy.
Prefer overloaded methods of v128 instead of _mm_... in VPKSHUS ppu interpreter precise.
Fixed more potential overflows that may result in wrong behaviour.
Added io/size alignment check for sys_rsx_context_iounmap.
Added rsx::constants::local_mem_base which represents RSX local memory base address.
Removed obsolute rsx:🧵:main_mem_addr/ioSize/ioAddress members.
- Allows render targets to behave like stacked 3D views same as shader inputs are resolved
- Basically implements most of 'Read Color/Depth Buffers" option for 'free'.
- Allows splitting RTV/DSV resources if they are superceded by a partial surface
- Also allows intersecting new resources through the surface cache for proper inheritance from other scattered data
- TODO: Refactor bind_surface_as_rtt and bind_surface_as_ds to reduce asinine code duplication
- Do not round up sub-pixel offsets, round down instead
- Do not allow incomplete sources for hw blit transfer
- Reimplement src clipping (slice_h)
- Check 'area' of incoming texels and correct for them before RTT lookup/transfer
- Filter out incomplete targets when performing RTT lookup (1 texel or less contribution)
- Avoids blindly reusing blit dst sections as they may contain garbage.
If a section was unlocked for a flush, just discard it as its reuse introduces potential data corruption.
Since the data needs to be reuploaded anyway (for now), its better to start afresh
- In case of format mismatch, reset the calculated dst block
- Add a bounds check to determine if data contained in an atlas is good enough for sampling the cache.
If not enough data is provided, fall back to full upload
