Profiling done with two samples on Solar v2.1 from rpcs3 init to first frame.
Before optimization, profiler found rpcs3 in cellPngDecDecodeData 15.3% of the time.
Post-optimization, profiler finds rpcs3 in cellPngDecDecodeData 0.33% of the time for ~50x improvement.
It seems strange, but Sonic CD passes bytesPerLine = w * 3 for a 4 channel
image. Either this is a bug elsewhere, or it ignores likely incorrect
strides.
Untested except in Sonic CD.
This handles CELL_PNGDEC_BOTTOM_TO_TOP and also handles reduced
outputBytesPerLine more correctly-looking. Not actually tested against
actual behavior.
* various changes to make it compile with clang
* don't compile recompiler on linux yet but make the CMake build include asmjit already
* add experimental travis bot
* modify yml to match
* try to build and install wxWidgets, since it's not in the travis repo
* use newer cmake version for travis
* add keys with sudo
* use sudo for all apt- commands
* Add additional dependencies
* use version approriate gcc flags for c++11
* try clang, gcc too old
* set c++0x flag for clang
* use gcc 4.8
* use gcc 4.8 and add the repo for it
* use gcc 4.8 even for clang to get newer headers
* fix ambiguous conversions
* add lz from hykem and more explicit conversions from be for x86
* more switch disambiguation
* more switch disambiguation
* add additional unigned int casts to deal with be_t conversion ambiguity
* remove unnecessary clang flag
* add lz.cpp to vcxproj and cast to u32 instead of unsigned int
* correct temporaray #ifdefs
* This commit solves the cellPngDec GetMemFromAddr(0x0) error when
loading PNGs from files.
* cellVideoOutGetResolution, cellRtc* syscalls rewritten to use the use
the mem*_t data types.
* Replaced int/uint with s32/u32 in some syscall arguments and structs.
* Small cleanup in cellJpgDec and cellPngDec.
* cellPamf added to the project and a few test lines added to
cellPamfGetHeaderSize(2).
* Improved speed of the Raw Image Preview on the the Memory Viewer.
* Now you can click on the shown buffers / textures in the RSX Debugger
in order to see them in full size. More settings added to the tabs.
* Fixed cellFsStat in order to fix the crash aused by opening
directiories. The solution is really *really* ugly. Once vfsDir is
ready, I will replace it with something better.
* Improved image decoding modules:
- Fixed error that appeared after last commit (eebe859f83).
- Changed some functions to use the mem*_t classes.
- Implemented cell*DecSetParameter.
* Created new dummy modules for sys_net (0x0000), sys_http (0x0001),
cellHttpUtil (0x0002) and cellSsl (0x0003).
* Huge improvement in the speed of cell{Png|Gif|Jpg}DecDecodeData when
reading input files.
Note: Sorry if this commit is too "small", but I need to sync every
change since I use two PCs.
*Improved Keyboard:
- Fixed crash when using Null keyboard handler
- Added support for meta keys
- Added support for {caps, num, scroll} lock.
*Small issues fixed in previous module:
- cellGifDec: Fixed wrong information of packet field in
cellGifDecReadHeader.
- cellGifDec: Set DataOutInfo.recordType as 1 since the output is always
an image.
- cellJpgDec: Set colorSpace as 3, until a better function is
implemented.
- cellJpgDec, cellPngDec: Added RGBA support.
*Changed layout of "Config > Settings" menu.
*Implemented 'cellGifDec', using 'sys_fs' to access the files and the
'stb_image' (stblib) library to decode GIF buffers to Raw-pixel buffers
that can be used as textures.
*Replace 'lodepng' and 'jpeg-compressor' libraries with 'stb_image' in
cellPngDec and cellJpgDec, respectively.
*Fixed minor issues in cellPngDec and cellJpgDec.
*Replaced "sys_jpgdec" with "cellJpgDec" in
"rpcs3\Emu\SysCalls\Modules.cpp".
*Implemented 'cellJpgDec', using 'sys_fs' to access the files and the
'jpg-compressor' (jpgd) library to decode JPG buffers to Raw-pixel
buffers that can be
used as textures.
*Fixed memory leak issue in cellPngDec and minor changes.
Implemented 'cellPngDec', using 'sys_fs' to access the files and the
'lodepng' library to decode PNG buffers to Raw-pixel buffers that can be
used as textures.
