* r300: Texture size limit cleanups.Michel Dänzer2009-03-254-6/+23
| | | | | | | | | 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...
* i965: fix point rasterization when rendering to FBORobert Ellison2009-03-242-1/+45
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* i965: Fix glFrontFacing in twoside GLSL demo.Eric Anholt2009-03-238-38/+79
| | | | | | | 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.
* i965: Fix fog coordinate g,b,a values when glFrontFacing isn't used.Eric Anholt2009-03-231-0/+50
| | | | | | | | | 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.

* i965: Fix occlusion query when no other WM state updates occur.Eric Anholt2009-03-231-2/+3
| | | | | | | | | Turns out that XXX comment was important. We weren't flagging the WM to re-update with the statistics enable, so we got zeroes out of our query. Bug #20740, fixes piglit occlusion_query test. Signed-off-by: Eric Anholt <[email protected]>
* Fix DRI2 accelerated EXT_texture_from_pixmap with GL_RGB format.Eric Anholt2009-03-206-15/+51
| | | | | | | | | | | | | | This requires upgrading the interface so that the argument to glXBindTexImageEXT isn't just dropped on the floor. Note that this only fixes the accelerated path on Intel, as Mesa's texture format support is missing x8r8g8b8 support (right now, GL_RGB textures get uploaded as a8r8gb8, but in this case we're not doing the upload so we can't really work around it that way). Fixes bugs with compositors trying to use shaders that use alpha channels, on windows without a valid alpha channel. Bug #19910 and likely others as well.

* i965: fix polygon stipple when rendering to FBORobert Ellison2009-03-121-4/+31
| | | | | | | | | | | | | | | The polygon stipple pattern, like the viewport and the polygon face orientation, must be inverted on the i965 when rendering to a FBO (which itself has an inverted pixel coordinate system compared to raw Mesa). In addition, the polygon stipple offset, which orients the stipple to the window system, disappears when rendering to an FBO (because the window system offset doesn't apply, and there's no associated FBO offset). With these fixes, the conform triangle and polygon stipple tests pass when rendering to texture.

* i965: fix polygon face orientation when rendering to FBORobert Ellison2009-03-111-2/+8
| | | | | | | | | | | | | | In the i965, the FBO coordinate system is inverted from the standard OpenGL/Mesa coordinate system; that means that the viewport and the polygon face orientation have to be inverted if rendering to a FBO. The viewport was already being handled correctly; but polygon face was not. This caused a conform failure when rendering to texture with two-sided lighting enabled. This fixes the problem in the i965 driver, and adds to the comment about the gl_framebuffer "Name" field so that this isn't a surprise to other driver writers.

| | | | | | | | | This function scans the shader to see if it has any GLSL features like conditionals and loops. Calling this during state validation is expensive. Just call it when the shader is given to the driver and save the result. There's some new/temporary assertions to be sure we don't get out of sync on this.
