* changed _mesa_rescale_teximage2d to allow rescaling of padded imagesDaniel Borca2004-10-182-12/+17
|
* added dstRowStride to dxtCompressTexFuncExt;Daniel Borca2004-10-181-5/+5
| | | | | | | | good for subimages, padded images and such. NB: intentionally, this is the last parameter, to avoid breaking the current API! adding a new parameter is not harmful, at worst it will be ignored, since all platforms use a CDECL calling convention.
* use RowStride instead of Width in texel fetchers.Daniel Borca2004-10-181-11/+11
| | | | changed some pointers to be (char *) instead of (long)
* Fix compile errors when DEBUG is defined.Ian Romanick2004-10-182-5/+5

* Fix t_vertex byte-ordering issues for PowerPC. This was tested with gearsIan Romanick2004-10-171-0/+20

| | | | | | | | | | | | | | | coordinate generation. Original code by Roland Schiedegger, with changes by myself. While here, ensure that the swtcl path does tnl_install_attrs enough when fog/specular are being (en/dis)abled. Notable effects: - projtex test works with TCL and is closer with swtcl (Bugzilla #1461) - 8/9 squares work in texgenmix instead of 3. - texcyl "reflect" mode works (GL_SPHERE_MAP is now a fallback -- unclear if the hardware can actually support it). - flickering in doom3 replaced by just plain darkness. - blocktube fixed (Bugzilla #984) - fixes stex3d
* Always turn on the TAM_DEBUG3=0x6 workaround on real r200s. It appears thatEric Anholt2004-10-161-2/+8
| | | | | | | the current cases for turning it on were insufficient (Bugzilla #1519, 729, 814) and it has no significant performance impact. Performance tested with quake3 in GL_LINEAR mode both with and without anisotropy, with the workaround always on or always off.
* Add support for OES_read_format. As soon as glext.h is updated with theIan Romanick2004-10-164-0/+36
| | | | enums for this extension, the changes to gl.h can be removed.
* fix if/else bug in _mesa_ProgramEnvParameter4fARB (fdo bug 1645)Brian Paul2004-10-161-2/+2

* Only build the MMX/SSE/SSE2 versions for ReadRGBASpan when the pixel formatIan Romanick2004-10-161-3/+12

* Fixed a few places that should have been using GET_SRC_PTR.Ian Romanick2004-10-151-3/+3

* Convert MGA driver to use new spantmp2.h interface.Ian Romanick2004-10-151-70/+27
|
* Huge dumb drop. State:Nicolai Haehnle2004-10-1513-59/+296
| | | | | | | | | | - Color buffer clear is accelerated, but flickers (possibly caused by a recent DDX or Mesa change or bad merge) - Everything else uses software fallback rendering - There should be no clipping-related artifacts with the sw-clipspan-fixes.patch against Mesa (posted on dri-devel) - Multiple clients should be rock solid with a DDX patch that is soon to come (soon = within the next hour or so)
* Add support for optimized versions of the code underlying ReadPixelsIan Romanick2004-10-147-193/+1114
| | | | | | | | | (and DrawPixels). The R200, R128, and Unichrome drivers get support in this commit. Other drivers would be easy enough to add for people that have the cards. The DRI (CVS) build will need to be updated to account for the new source files.
* Add a license to this file. It was written on VA's watch, so they getKeith Whitwell2004-10-131-0/+29

* Added some documentation that I managed to figure out throughIan Romanick2004-10-131-17/+27
| | | | experimentation.
* Make the GL_RENDERER string include the actual chipset informationIan Romanick2004-10-131-8/+16
| | | | instead of always saying "CLE266".
* Initial support for PowerPC specific code in Mesa and DRI drivers. DRIIan Romanick2004-10-135-6/+175
| | | | | | | | | drivers built on PowerPC systems should now show things like "PowerPC" or "PowerPC/Altivec" in the GL_RENDERER string. The VMX moniker is used for Altivec/Velocity Engine/VMX SIMD additions. I chose this not because I work for IBM but because it's a LOT shorter to type. :)
* Refactor the code in driGetRendererString a bit to make it easier toIan Romanick2004-10-131-15/+40
| | | | add support for features of non-x86 CPU types.
* Eliminate the funky SSE exception test from DRI builds. It's not needIan Romanick2004-10-131-6/+16
| | | | (see the comment in the code), and it's just annoying.
* Fix minor fog / fragment program state bug.Brian Paul2004-10-134-26/+29
| | | | Don't add diffuse and specular colors when using fragment program.
* Bug #1588: abort if no palette format matches. (Egbert Eich, Stefan Dirsch)Adam Jackson2004-10-131-0/+1

* Fix a potential memory leak.Philippe Houdoin2004-10-131-1/+2
|
* Implement BGLView::CopyPixelsIn/Out().Philippe Houdoin2004-10-131-24/+137
| | | | | BGLView::ErrorCallback() is now actually called on error! Plus usual minor changes.
* support for external librariesDaniel Borca2004-10-122-0/+2

* Prefix operator and constructor keywords with two consequtive underscoresMichal Krol2004-10-111-327/+327
| | | | ( __ ). This will be more compatible with glslang spec.
* Enable draw_buffers only if GL_ARB_draw_buffers string isMichal Krol2004-10-111-1/+12

* This statechange is vtx state, not tcl.Eric Anholt2004-10-091-1/+1
|
* Use the right FALLBACK macro for projtex so that projective textures actuallyEric Anholt2004-10-081-11/+7
| | | | cause a fallback, and simplify the tmu handling a little.
* Add fallback debugging (R128_DEBUG=fall) output, and set DO_DEBUG=1 by defaultEric Anholt2004-10-084-13/+52
| | | | | so that we can use the env var to get output. Add a no_rast driconf option to force software fallbacks.
* Don't compile WriteMonoDepthSpan if HAVE_HW_DEPTH_SPANS is defined -- it won'tEric Anholt2004-10-081-0/+2
| | | | | be used in that case, and it wanting WRITE_DEPTH was making r128 die on the undefined symbol.
* Add support for NV_blend_square, and print errors if an unsupported blendEric Anholt2004-10-083-10/+27

* Massively cleaned up the code that calculates front/back/depth bufferIan Romanick2004-10-084-342/+126

* Add Roland Scheidegger's S3TC patch. This patch does not implement theEric Anholt2004-10-0725-44/+627
| | | | | | | | | | | | | | | | | (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.
* Prevent Y-offset from exceeding valid range in texture upload code. ThisIan Romanick2004-10-071-0/+8
