* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-0813-7/+234
| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.
* st/mesa: Fix an incorrect user vertex buffer referenceThomas Hellstrom2011-03-081-4/+2
| | | | | | | | st->user_vb[attr] was always pointing to the same user vb, regardless of the value of attr. Together with reverting the temporary workaround for bug 34378, and a fix in the svga driver, this fixes googleearth on svga. Signed-off-by: Thomas Hellstrom <[email protected]>

* swrast: add coord clamping, fix comparisons for shadow testingPhilip Taylor2011-03-081-27/+30
| | | | | | | | | This fixes https://bugs.freedesktop.org/show_bug.cgi?id=31159 for swrast and piglit depth-tex-compare. NOTE: This is a candidate for the 7.10 branch. Signed-off-by: Brian Paul <[email protected]>

* r300/compiler: improve the detection of constants for constant foldingMarek Olšák2011-03-081-0/+7
| | | | Now the expression V==0 generates one instruction instead of two.
* r300/compiler: saturate Z before the shadow comparisonMarek Olšák2011-03-081-37/+44
| | | | | | | This fixes: https://bugs.freedesktop.org/show_bug.cgi?id=31159 NOTE: This is a candidate for the 7.9 and 7.10 branches.
* mesa: return after invalidating renderbufferMarek Olšák2011-03-071-0/+1

* st/mesa: fail to alloc a renderbuffer if st_choose_renderbuffer_format failsMarek Olšák2011-03-071-1/+5
| | | | | | This fixes: state_tracker/st_format.c:401:st_pipe_format_to_mesa_format: Assertion `0' failed.
* mesa: invalidate framebuffer if internal format of renderbuffer is changedMarek Olšák2011-03-072-6/+31
| | | | RenderTexture doesn't have to be called in invalidate_rb, I guess.
* mesa: initialize DummyBufferObject's mutexBrian Paul2011-03-071-0/+1
| | | | | | The mutex's fields were all zeros. That's OK on Linux, but not Windows. NOTE: This is a candidate for the 7.10 branch.
* st/mesa: fix incorrect version checking codeBrian Paul2011-03-071-2/+3

* mesa: remove stray _mesa_finish() call in _mesa_CopyPixels()Brian Paul2011-03-071-2/+0
| | | | Leftover debug code from 6364d75008b4fa580c1cb47c59ba1cf3e0caa6cd.
* i915: Only invert wpos when rendering to the system framebuffer.Henri Verbeet2011-03-071-7/+15

* i915: Derive the gl_fragment_program from i915_fragment_program.Henri Verbeet2011-03-071-6/+5
| | | | | | Instead of using the current gl_fragment_program. These aren't necessarily the same, for example when translate_program() is called by i915ValidateFragmentProgram().

* glx/dri: add initial dri interface for GLX_EXT_framebuffer_sRGB.Dave Airlie2011-03-061-0/+3
| | | | This realigns the name of the glx bit to align with the core mesa names.
* gallium: split CAP_INSTANCE_DRAWING into INSTANCEID and INSTANCE_DIVISORMarek Olšák2011-03-051-1/+3
| | | | | | | | ARB_instanced_arrays is a subset of D3D9. ARB_draw_instanced is a subset of D3D10. The point of this change is to allow D3D9-level drivers to enable ARB_instanced_arrays without ARB_draw_instanced.
* i965: Apply a workaround for the Ironlake "vertex flashing".Eric Anholt2011-03-041-1/+8
| | | | | | | | | | | | | | This is an awful hack and will hurt performance on Ironlake, but we're at a loss as to what's going wrong otherwise. This is the only common variable we've found that avoids the problem on 4 applications (CelShading, gnome-shell, Pill Popper, and my GLSL demo), while other variables we've tried appear to only be confounding. Neither the specifications nor the hardware team have been able to provide any enlightenment, despite much searching. https://bugs.freedesktop.org/show_bug.cgi?id=29172 Tested by: Chris Lord <[email protected]> (Pill Popper) Tested by: Ryan Lortie <[email protected]> (gnome-shell)
* st/mesa: set PIPE_BIND_RENDER_TARGET for sRGB formats if UNORM is supportedMarek Olšák2011-03-041-2/+9
| | | | | | | | Because the format can be changed to UNORM in a surface. This fixes: state_tracker/st_atom_framebuffer.c:163:update_framebuffer_state: Assertion `framebuffer->cbufs[i]->texture->bind & (1 << 1)' failed.
* i965: Fix extending VB packetsChris Wilson2011-03-041-2/+2
| | | | | | | | Computation of the delta of this array from the last had a silly little bug and ignored any initial delta==0 causing grief in Nexuiz and friends. Signed-off-by: Chris Wilson <[email protected]>
* i965: Handle URB_FENCE erratum for BroadwaterChris Wilson2011-03-041-0/+8
| | | | | | | | | | There is a silicon bug which causes unpredictable behaviour if the URB_FENCE command should cross a cache-line boundary. Pad before the command to avoid such occurrences. As this command only applies to gen4/5, do the fixup unconditionally as the specs do not actually state for which chip it was fixed (and the cost is negligible)...

* Revert "mesa: reduce calls to _mesa_test_framebuffer_completeness()"Brian Paul2011-03-021-1/+1
| | | | | | | This reverts commit 1f9a0a4e6e5566c36c781add5f1e62af3efdfb58. This caused trouble with Lightsmark w/ i965 driver and fbo/fbo-blit-d24s8 (see bug 34894). It's probably something simple but no time to debug now.

| | | | | | | | | SNB has 64k urb space, we only use piece of them. The more urb space we alloc, the more concurrent vs threads we can run. push the urb space usage to the limit. Signed-off-by: Zou Nan hai <[email protected]>

* mesa/st: fix generate mipmap for signed compressed formats.Dave Airlie2011-03-021-32/+63
| | | | | | | | This was always converting to 8-bit per channel unsigned formats, which isn't suitable for RGTC signed formats, this special cases those two formats and converts to floats for those. Signed-off-by: Dave Airlie <[email protected]>

* rgtc: fix issues with compressor and signed types.Dave Airlie2011-03-022-10/+23
| | | | | | | | | | With signed types we weren't hitting this test however the comment stating this doesn't happen often doesn't apply when using signed types since an all 0 block is quite common which isn't abs min or max. this fixes the limits correctly again also.

* vbo: add vbo_always_unmap_buffers()Brian Paul2011-03-013-1/+22
| | | | | | Drivers can call this function as needed. It tells the VBO module to always unmap the current glBegin/glEnd VBO when we flush. Otherwise it's possible to be in a flushed state but still have the VBO mapped.
