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
- Load into memory as straightforward BGRA
- Fixes a bug in vulkan caused by byte shuffling in blit engine vs shader access
- Removes the need for memory shuffling when transferring into a rendertarget
- 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
- Texel borders are no longer actually supported in modern APIs
- Removes the border texels and uses border color instead which is incorrect but should work fine
- Revert to using block metrics, but with optional per-channel decode
stage for the final transfer. Much cleaner than hacking in the width to
be in channels instead of blocks.
- Removes CPU-only transforms that broke GPU-side code.
-- Channels in GPU compute are laid out in cell-order, but CPU was uploading in favorable order and compensating with swizzles.
-- This leads to 2 different layouts depending on the location of the data (CPU vs GPU)
- Implement R8G8_R8B8 interleaved format decode
- General improvements
- Some formats are proven to ignore swizzle flag
- DXT compressed textures
- COMPRESSED_BG_GB class textures
- Some applications are using swizzled wide integer formats so those are confirmed to swizzle
- 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
