* swrast: asst. clean-ups in texcombine codeBrian Paul2009-04-061-26/+19
|
* swrast: fix secondary color add for glBitmapBrian Paul2009-04-063-11/+30
| | | | | Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
* swrast: fix incorrect arithmetic for GL_ADD_SIGNED/GL_COMBINE4_NV modeBrian Paul2009-04-061-6/+6
|
* st: as with swrast, interpret texture border color according to texture formatBrian Paul2009-04-061-4/+37
| | | | | Depending on the hardware driver this might not be needed, but it will cause no harm.
* st: rename a helper functionBrian Paul2009-04-061-4/+4

* swrast: fix texture border color interpretationBrian Paul2009-04-061-30/+68
| | | | | | | The texture border color must be interpreted according to the texture's base format. For example, for a GL_ALPHA texture, sampling the border color should return (0,0,0,borderAlpha). This wasn't an issue here until I removed the legacy texenv code (we always use the combiner path now).
* mesa: Fix orientation adjustment for reading stencil pixels.José Fonseca2009-04-061-1/+1
| | | | Fixes conform spcorner.c & spclear.c failure.
* intel: Avoid dri2 GetBuffers round-trips for internal Viewport calls.Eric Anholt2009-04-063-3/+10
| | | | | | This gets us the savings for driver-internal viewport calls that dd1c68f15123a889a3ce9d2afe724e272d163e32 was attempting, without relying on Xlib internals or clients handling X events.
* i965: Use GTT maps when available to upload vertex arrays and system VBOs.Eric Anholt2009-04-063-18/+55
| | | | | | | This speeds up OA on my GM45 by 21% (more than the original CPU cost of the upload path). We might still be able to squeeze a few more percent out by avoiding repeatedly mapping/unmapping buffers as we upload elements into them.
* intel: Clean up some a leftover from sedding of bufmgr context->screen move.Eric Anholt2009-04-061-3/+0

* radeon: Expose a 32 bit RGBA fbconfig even when the screen depth is 16.Michel Dänzer2009-04-061-15/+20
| | | | | | | Otherwise current xserver / libGL no longer expose a 32 bit RGBA GLX visual, and compiz fails. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=20479 .
* gallium: Clean up driver clear() interface.Michel Dänzer2009-04-041-119/+64
| | | | | Only allows clearing currently bound buffers, but colour and depth/stencil in a single call.
* gallium: Add utility helper for packing combined depth/stencil values.Michel Dänzer2009-04-041-13/+3

* intel: #include texgetimage.hBrian Paul2009-04-031-0/+1
|
* mesa: move glGetTexImage(), glGetCompresssedTexImage() code into new fileBrian Paul2009-04-039-335/+409
|
* mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul2009-04-038-15/+18
| | | | | It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
* mesa: clamp colors to [0,1] for glGetTexImage() when format is GL_LUMINANCEBrian Paul2009-04-031-4/+6
| | | | For luminance, we add R+G+B and it seems we should always clamp in case.
* mesa: whitespace and comment clean-upBrian Paul2009-04-031-11/+16
|
* mesa: remove extra semicolonsBrian Paul2009-04-031-5/+5
|
* mesa: in mesa_add_named_constant(), avoid adding duplicate constantsBrian Paul2009-04-031-7/+12
|
* mesa: fix parameter counting in ARB vertex/fragment program parsingBrian Paul2009-04-031-5/+2
| | | | Duplicated unnamed constants were getting counted more than once.
* mesa: replace >= with > when testing if we've exceeded max local paramsBrian Paul2009-04-031-2/+2
| | | | Now a program that uses 256 locals works as it should.
* mesa: only clear matrix MAT_DIRTY_INVERSE flag when we actually compute the ↵Brian Paul2009-04-031-3/+2
| | | | | | | | inverse If _math_matrix_analyse() got called before we allocated the inverse matrix array we could lose the flag indicating that we needed to compute the inverse. This could happen with certain vertex shader cases.
* mesa: for OPCODE_LIT, use _mesa_pow() instead of exp() and log()Brian Paul2009-04-031-2/+2
| | | | Also, s/pow/_mesa_pow/
* mesa: rename some gl_light fields to be clearerBrian Paul2009-04-0310-36/+36
| | | | | EyeDirection -> SpotDirection _NormDirection -> _NormSpotDirection
* mesa: don't normalize spot light direction until validation timeBrian Paul2009-04-031-2/+7
| | | | | In glLight() we're only supposed to transform the direction by the modelview matrix, not normalized it too.
* i965: remove unused varBrian Paul2009-04-031-1/+0

* mesa: replace assertion with conditional in _mesa_opcode_string()Brian Paul2009-04-031-2/+4

|
* i965: another checkpoint commit of new constant buffer supportBrian Paul2009-04-032-65/+115
| | | | | Everything is in place now for using a true constant buffer for GLSL fragment shaders. Still some bugs to find though.
* i965: fix response length param in brw_dp_READ_4()Brian Paul2009-04-031-1/+1
| | | | We were accidentally clobbering the next register.
* i965: change args to get_src_reg() to prep for new constant buffer supportBrian Paul2009-04-031-79/+85
|
* i965: check-point commit of new constant buffer supportBrian Paul2009-04-035-35/+288
| | | | | | | | | | | | | | | | Currently, shader constants are stored in the GRF (loaded from the CURBE prior to shader execution). This severly limits the number of constants and temps that we can support. This new code will support (practically) unlimited size constant buffers and free up registers in the GRF. We allocate a new buffer object for the constants and read them with "Read" messages/instructions. When only a small number of constants are used, we can still use the old method. The code works for fragment shaders only (and is actually disabled) for now. Need to do the same thing for vertex shaders and need to add the necessary code-gen to fetch the constants which are referenced by the shader instructions.

* i965: code to setup a constant buffer samplerBrian Paul2009-04-031-0/+43
| | | | | This code won't actually be used and will be removed in a subsequent commit. Just committing for posterity.

| | | | | Call the get_src_reg_imm() function when it's permissible to generate a literal value src register.
