2007-09-29r200: Implement SetTexOffset hook.Chris Rankin
Implementation guidance by Michel Dänzer, final testing by Timo Aaltonen.

2006-09-20try to use a 8888 texture format which will result in only a memcopy in ↵Roland Scheidegger
mesa's texstore functions whenever possible for r200 and r300. r200 can use hw formats argb8888, rgba8888 and abgr8888 (or the opposite on big endian), r300 can use argb8888, bgra8888, rgba8888 and abgr8888 regardless of endian, as it supports free component swizzling.
2005-08-25Attempt to fix the issue reported by Alan Grimes with DRM_RADEON_TEXTUREEric Anholt
erroring out when it shouldn't. The errno could be changed by usleep() between the ioctl call and the loop check, if a signal was received. This could cause an EAGAIN return from the DRM_RADEON_TEXTURE ioctl to not loop again. Instead of checking errno, check thevalue of ret itself, since it is a saved (and sign-flipped) copy of errno from the ioctl call.
2005-02-10add texture micro and macro tiling to radeon/r200 driver. This can improve ↵Roland Scheidegger
performance up to 15% in texture-intensive applications. Convert the driver to use the correct blit format and blit width instead of fixed blit format and blit width when uploading textures to make it work.
2004-10-07Add Roland Scheidegger's S3TC patch. This patch does not implement theEric Anholt
(patented) S3TC/DXTC algorithms, but adds an option to dlopen a library module providing functions to do so. Because it uses dlopen, it is only enabled if USE_EXTERNAL_DXTN_LIB=1 is defined (which is only in linux-dri config, so far). It adds support for S3TC to several DRI drivers, and adds a DRI config option to force enabling S3TC even if the software compression/decompression is unavailable. This may allow people to use apps that require S3TC even though they don't have a license to implement the patented material themselves, if those apps use precompressed textures. Ideally we would get permission from the current holder of the patents to implement the algorithm in Mesa, at which point the dlopen mess could go away. Until then, this allows some to run applications they couldn't otherwise, and hopefully will provide us with more push to get the final step of getting that permission done.
2004-10-07Prevent Y-offset from exceeding valid range in texture upload code. ThisIan Romanick
fixes bugzilla #960.
2004-09-25Fix texturing in quake3. Some code was left over from the dirty/clean listEric Anholt
setup that now removed atoms from the atomlist on texture deletion.

2004-02-06align blits for texture rectangles correctly, fix potential problem ↵Roland Scheidegger
overwriting dma region
2004-01-27Consolidate texObj->Pos/Neg/X/Y/Z and texObj->Image into a singleKeith Whitwell
array, texObj->Image[face][level].
2003-12-11Updates to tnl_dd_dmatmp.hKeith Whitwell
- Allocate vertices explicitly, rather than trying to talk about dma buffers. - Clean up the various Flush() operations. - Don't allow fallbacks any longer. Provide a support function to detect them ahead o ftime Updates to tnl_dd_vbtmp.h - Get rid of power-of-two vertex strides. Pack all vertices tightly. - Get texunit 2,3 emit working coorrectly. Other stuff: - Get rid of lingering Ubyte color support. - Fix a few compiler warnings.
