* mesa: Fix Sparc cliptest asm code and re-enable.David Miller2009-02-272-22/+11
| | | | | | | | | | | | | | Stop using register %g7 since that is used by the "system" (ie. the pthread implementation makes use of it). Also, the projection vector can be NULL and we shouldn't try to access it at all in _mesa_sparc_cliptest_points4_np(). ioquake3 would crash due to this bug. Finally, unconditionally emit the register directives and re-enable in _mesa_init_all_sparc_transform_asm(). Signed-off-by: David S. Miller <[email protected]>
* mesa: Fix DEBUG_MATH build on sparc.David S. Miller2009-02-261-2/+2
| | | | | | | | | | Need to use '__asm__' instead of plain 'asm'. math/m_debug_clip.c: In function ‘test_cliptest_function’: math/m_debug_clip.c:253: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘asm’ math/m_debug_clip.c:253: warning: implicit declaration of function ‘asm’ Signed-off-by: David S.

* intel: no-op the intel_finish_render_texture() functionBrian Paul2009-02-261-13/+10
| | | | It doesn't have to do anything. See comments for more details.
* intel: check texture formats in intel_validate_framebuffer()Brian Paul2009-02-261-0/+29
| | | | | | | | | We can't render into any texture format; only certain formats. Check that render-to-texture's format is renderable in the intel_validate_framebuffer() There seems to be a bug somewhere that causes rendering to rgb565 textures to be corrupted so disallow that for now. This will be revisted.

* i965: rename draw_regions -> color_regionsroot2009-02-264-20/+20
| | | | Be a little more specific about what these are.
* mesa: avoid extraneous calls to ctx->Driver.BindFramebuffer()Brian Paul2009-02-261-6/+13
| | | | Only call this driver function when we really need to bind different buffers.
* i965: add missing init for region->widthBrian Paul2009-02-261-1/+2
| | | | | This doesn't seem to really effect anything but seeing width=0 in drawing regions was confusing.
* mesa: replace old prog_instruction::Sampler field with Aux fieldBrian Paul2009-02-264-18/+12
| | | | | | The i965 driver needs an extra instruction field for color output information. It was using the Sampler field for this. Use the Aux field instead. This will probaby be revisited at some point...

* mesa: Resurrect SPARC asm code.David S. Miller2009-02-267-1246/+878
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rewrites the sparc GLAPI code so that it's PIC friendly and works with all of the TLS/PTHREADS/64-bit/32-bit combinations properly. As a result we can turn SPARC asm back on. Currently it's only enabled on Linux, as that's the only place where I can test this stuff out. For the moment the cliptest SPARC asm routines are disabled as they are non-working. The problem is that they use register %g7 as a temporary which is where the threading libraries store the thread pointer on SPARC. I will fix that code up in a future change as it's a pretty important routine to optimize. Like x86 we do the runtime patch as a pthread once-invoked initializer in init_glapi_relocs(). Unlike x86, however, our GLAPI stubs on SPARC are just two instruction sequences that branch to a trampoline and put the GLAPI offset into a register. The trampoline is what we run-time patch. The stubs thus all look like: glFoo: ba __glapi_sparc_foo_stub sethi GLAPI_OFFSET(glFOO) * PTR_SIZE, %g3 This actually makes generate_entrypoint() a lot simpler on SPARC. For this case in generate_entrypoint() we generate stubs using a 'call' instead of the 'ba' above to make sure it can reach. In order to get a proper tail call going here, in the unpatched case, we do several tricks. To get the current PC, for example, we save the return address register into a temporary, do a call, save the return address register written by the call to another temporary, then restore the original return address register value. This is to avoid having to allocate a stack frame. This is necessary for PIC address formation. This new GLAPI scheme lets us get rid of the ugly SPARC GLAPI hacks in __glXInitialize() and one_time_init(). Signed-off-by: David S. Miller <[email protected]>

* Fix "cast to pointer from integer of different size"Tomas Carnecky2009-02-261-1/+1
| | | | | | | | | The script generates code like: pixels = (const GLvoid *) (ptr_is_null != 0) ? NULL : (pc + 80); which causes the above mentioned warning. Add parenthesis around the whole expression to fix it. Signed-off-by: Tomas Carnecky <[email protected]>
* i965: fix for RHW workaroundXiang, Haihao2009-02-262-43/+99
| | | | | | It is possible that an object whose vertices all are outside of a view plane is passed to clip thread due to the RHW workaround. This object should be rejected by clip thread. Fix bug #19879
* intel: Disable creating DRI2 FBconfigs with depth size != color size.Eric Anholt2009-02-261-1/+22
| | | | | | | | | | While it's a nice idea to be able to allow clients to choose a smaller (or bigger for 16bpp screens!) depth size, right now DRI2 hands back a buffer with a size that matches the drawable, rather than being based off of the visual. This led to problems in readback as parts of the driver disagreed on what format the depth buffer was really in. Fixes the remainder of bug #19447.
* intel: Add span code for z24 without stencil.Eric Anholt2009-02-261-2/+22
| | | | | | | | It seems that in this case the Mesa code is handing us x8z24 values instead of z24s8 values, so we need to not do the rotation. Fixes half of OGLconform depthrange.c. Bug #19447.
* intel: make template wrappers for the spans templates.Eric Anholt2009-02-254-189/+165
| | | | | This is insanity, but so is copying the same blocks containing the actual interesting code in the file three times each for the different tile formats.
* intel: Fix up x8r8g8b8 renderbuffer format so that alpha=1 spans code happens.Eric Anholt2009-02-252-1/+17
| | | | | | | | I was lured into a false sense of security by the fact that the spans code was already there, and a bunch of tests didn't catch the problem. oglconform's mask.c did, though. Bug #19970.

* glsl: fix another swizzle-related bugBrian Paul2009-02-231-13/+8
| | | | | | | This fixes the case of "infinitely" nested swizzles such as EXPR.wzyx.yxwz.xxyz This doesn't appear in typical shaders but with function inlining and the compiler's internal use of swizzles it can happen. New glean glsl1 test case added for this.

* i965: fix line stipple fallback for GL_LINE_STRIP primitivesRobert Ellison2009-02-231-1/+1
| | | | | | | | | | When doing line stipple, the stipple count resets on each line segment, unless the primitive is a GL_LINE_LOOP or a GL_LINE_STRIP. The existing code correctly identifies the need for a software fallback to handle conformant line stipple on GL_LINE_LOOP primitives, but neglects to make the same assessment on GL_LINE_STRIP primitives. This fixes it so they match.
