2009-04-06intel: Avoid dri2 GetBuffers round-trips for internal Viewport calls.Eric Anholt
This gets us the savings for driver-internal viewport calls that dd1c68f15123a889a3ce9d2afe724e272d163e32 was attempting, without relying on Xlib internals or clients handling X events.
2009-04-06i965: Use GTT maps when available to upload vertex arrays and system VBOs.Eric Anholt
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.
2009-04-06intel: Clean up some a leftover from sedding of bufmgr context->screen move.Eric Anholt
2009-04-06radeon: Expose a 32 bit RGBA fbconfig even when the screen depth is 16.Michel Dänzer
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 .

2009-04-03i965: another checkpoint commit of new constant buffer supportBrian Paul
Everything is in place now for using a true constant buffer for GLSL fragment shaders. Still some bugs to find though.
2009-04-03i965: fix response length param in brw_dp_READ_4()Brian Paul
We were accidentally clobbering the next register.
2009-04-03i965: change args to get_src_reg() to prep for new constant buffer supportBrian Paul
2009-04-03i965: check-point commit of new constant buffer supportBrian Paul
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.

This code won't actually be used and will be removed in a subsequent commit. Just committing for posterity.

2009-04-02dri glx: Fix dri_util::driBindContextThomas Hellstrom
1) Don't error-check here. It's done in glx makeCurrent. 2) Allow ctx and the dri drawables to be NULL for future use. This is currently blocked in glx makeCurrent. 3) Avoid updating dri drawables unless they are completely uninitialized. Since the updating was done outside of the lock, the driver need to verify and redo it anyway. Signed-off-by: Thomas Hellstrom <thellstrom-at-vmware-dot-com>

2009-03-30intel: Avoid mapping the texture image for CopyTex{,Sub}ImageAdam Jackson
We don't upload the pixels with the CPU in that case, so the map will only serve as a way of triggering cache flushes over a bunch of data we don't touch.
2009-03-28i965: srgb texture fixesRoland Scheidegger
i965 can either do SRGBA8_REV format or SARGB8 format, but not SRGBA8. Could add SRGBA8_REV support to mesa, but simply use SARGB8 for now. While here, also add true srgb luminance / luminance_alpha support - unfortunately the published docs fail to mention which asics support this, tested on g43 so assume this works on any g4x.

2009-03-25r300: Texture size limit cleanups.Michel Dänzer
Since core Mesa MAX_TEXTURE_LEVELS was bumped, we were incorrectly advertising a maximum texture size of 4096 on older chips, causing corrupted menu text in Extreme Tux Racer or Armagetron. Also make sure our texture image array can actually hold all the mipmap levels we support...
2009-03-24i965: fix point rasterization when rendering to FBORobert Ellison
The FBO pixel coordinate system, with (0,0) as the upper-left pixel, is inverted in Y compared to the normal OpenGL pixel coordinate system, which has (0,0) as its lower-left pixel. Viewport and polygon stipple are sensitive to this inversion; so is point rasterization. The basic fix is simple: when rendering to an FBO, instead of the normal RASTRULE_UPPER_RIGHT that's appropriate for OpenGL windows, use the Y inversion RASTRULE_LOWER_RIGHT. Unfortunately, current Intel documentation has this value listed as "Reserved, but not seen as useful". It does work on at least some i965-class devices, though; and the worst that could happen if an older device didn't support it would be incorrect point rasterization to FBOs, which is what happens already, so this fix is at least no worse than what happens presently, and is better for some (and possibly all) i965-class devices.
2009-03-23i965: Fix glFrontFacing in twoside GLSL demo.Eric Anholt
This also cuts instructions by just using the existing bit in the payload rather than computing it from the determinant in the SF unit and passing it as a varying down to the WM. Something still goes wrong with getting the backface color right, but a simpler shader appears to get the right result.
2009-03-23i965: Fix fog coordinate g,b,a values when glFrontFacing isn't used.Eric Anholt
Previously, we would sample (f,glFrontFacing,undef,undef) instead of the (f,0,0,1) that fragment.fogcoord is supposed to return. Due to glFrontFacing's presence in FOGC.y, we'll still give bad results there when glFrontFacing is used. Bug #19122, piglit testcase fp-fog.
