- Rare, but possible if a surface address is switched from color to depth usage
- In such a case, deref the old image and ref the new one to avoid leaks
- Replace old format-based detection with proper aspect test.
Explicit image aspect has been available for a long time, but older
code was not updated.
- Just use RGB565 for all blit targets. Avoids really dumb transforms done by GPU hw.
- When X16 is used, all the channels get written to R channel alone. CmdBlit does perform format conversion!
- gl: Force image copy when blit is requested with compatible targets. Avoids format conversion issues.
- Avoids a silly situation where a texture is discarded and an identical copy created immediately afterward.
Unfortunately allocating memory blocks is really slow so avoid it as much as possible.
- Each desc manages its own lifetime now instead of relying on global timestamp check
- Fixes situation where same object remains active without update for long
- Fix incorrect memory requirement calculation for D32FS8X24_PACK64 data type on GL
- Removes a lot of spaghetti code in GL backend from years of accumulation
- Retires several now-useless methods from RSX util toolbox
- Some texture accesses require image compositing steps to assemble the requested image from existing subresources.
Handle all the common routines in a unified manner to avoid having one broken path (e.g mipmap gather not supporting bitcast operations)
- Currently this conversion is being done on the CPU to reuse as much code as possible.
The expectation is that this almost never happens, so there is not point in increasing maintenance burden by adding compute paths
- Tracks which kind of raster was done (Z-ordered vs linear) throughout the application.
- This allows to identify if data is in the expected format or not.
SRC coordinates
- When extracting a 1x1 texture from another texture of a different
format, width conversion can result in a dimension of 0 if the
extracted texel is not a full texel in SRC
- Avoid double transfers where a transfer to a temp image is done
without scaling and then a secondary transfer follows. Combines the two
steps into one whenever possible which can significantly alleviate
bandwidth problems at higher resolutions. Significant speedup, upto 90%
in some cases (PDF, PDF2)
