2009-03-26i965: Fix glFrontFacing in twoside GLSL demo.Eric Anholt8-38/+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. (cherry picked from commit 699db6d842c52d0b3b98b320f8ef1104a65fa783)
2009-03-26i965: Fix fog coordinate g,b,a values when glFrontFacing isn't used.Eric Anholt1-0/+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.

2009-03-18i965: fix polygon stipple when rendering to FBORobert Ellison2-7/+34
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. (cherry picked from commit 29309b45b011b4c44721b8f7346272fb22a4d4c2)
2009-03-18i965: fix polygon face orientation when rendering to FBORobert Ellison2-4/+18
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. (cherry picked from commit 6dceeb2eb804d708639d68a13a924d65f366458a)
2009-03-17swrast: use better _swrast_compute_lambda() functionBrian Paul1-6/+6
The MAX-based function can produce values that are non-monotonic for a span which causes glitches in texture filtering. The sqrt-based one avoids that. This is perhaps slightly slower than before, but the difference probably isn't noticable given we're doing software mipmap filtering.

2009-03-13i965: check if we run out of GRF/temp registersBrian Paul1-2/+26
Before this change we would up emitting instructions with invalid register numbers. This typically (but not always) hung the GPU. For now, just prevent emitting bad instructions to avoid hangs. Still need to do some kind of proper error recovery. (cherry picked from commit e60b3067d81319236d63ad497e70658fd2e14eb3)

2009-03-13i965: fix emit_math1() function used for scalar instructionsBrian Paul1-9/+32
Instructions such as RCP, RSQ, LOG must smear the result of the function across the dest register's X, Y, Z and W channels (subject to write masking). Before this change, only the X component was getting written. Among other things, this fixes cube map texture sampling in GLSL shaders (since cube lookups involve normalizing the texcoord). (cherry picked from commit 348580197802406fc36219dc3f1ab90fbb8f4717)
2009-03-13i965: rewrite the code for handling shader subroutine callsBrian Paul6-64/+187
Previously, the prog_instruction::Data field was used to map original Mesa instructions to brw instructions in order to resolve subroutine calls. This was a rather tangled mess. Plus it's an obstacle to implementing dynamic allocation/growing of the instruction buffer (it's still a fixed size). Mesa's GLSL compiler emits a label for each subroutine and CAL instruction. Now we use those labels to patch the subroutine calls after code generation has been done. We just keep a list of all CAL instructions that needs patching and a list of all subroutine labels. It's a simple matter to resolve them. This also consolidates some redundant post-emit code between brw_vs_emit.c and brw_wm_glsl.c and removes some loops that cleared the prog_instruction::Data fields at the end. Plus, a bunch of new comments. (cherry picked from commit c51c822ee02cb47ddba46da668577d51b7c02831)
2009-03-13intel: Fix bpp setting of blits to 8bpp targets.Eric Anholt1-0/+2
This was causing hangs in cairogears, as we would blit to the 8bpp target (A8 texture) as 16bpp, and stomp over state objects. (cherry picked from commit 19e134051c1025bbfe3838108492d705ab2b5b8b)
2009-03-13i965: add software fallback for conformant 3D textures and GL_CLAMPRobert Ellison4-10/+40
The i965 hardware cannot do GL_CLAMP behavior on textures; an earlier commit forced a software fallback if strict conformance was required (i.e. the INTEL_STRICT_CONFORMANCE environment variable was set) and 2D textures were used, but it was somewhat flawed - it could trigger the software fallback even if 2D textures weren't enabled, as long as one texture unit was enabled. This fixes that, and adds software fallback for GL_CLAMP behavior with 1D and 3D textures. It also adds support for a particular setting of the INTEL_STRICT_CONFORMANCE environment variable, which forces software fallbacks to be taken *all* the time. This is helpful with debugging. The value is: export INTEL_STRICT_CONFORMANCE=2 (cherry picked from commit 34683150878e0af0859c94d0c1f0c4bf8395b042)
2009-03-13mesa: don't draw arrays if vertex position array is not enabledBrian Paul1-3/+12
For regular GL, we must have vertex positions in order to draw. But ES2 doesn't have that requirement (positions can be computed from any array of data). See bug 19911. (cherry picked from commit 97dd2ddbd97ba95e8bc8ab572ec05e8081556e1e)
2009-03-13i965: texture fixes: bordered textures, fallback renderingRobert Ellison1-3/+31
i965 doesn't natively support GL_CLAMP; it treats it like GL_CLAMP_TO_EDGE, which fails conformance tests. This fix adds a clause to the check_fallbacks() test to check whether GL_CLAMP is in use on any enabled 2D texture. If so, and if strict conformance is required (via INTEL_STRICT_CONFORMANCE), a software fallback is mandated. In addition, validate textures *before* checking for fallbacks, rather than after; otherwise, the texture state is never validated and can't be trusted. (In particular, if texturing is enabled and the sampler would access any level beyond level 0 of a texture, the sampler will segfault, because texture validation sets the firstLevel and lastLevel fields of a texture object so that the valid levels will be mapped and accessed correctly. If texture validation doesn't occur, only level 0 is accessed correctly, and that only because firstLevel and lastLevel happen to be set to 0.)

Replace Default1D/2D/3D/Cube/etc with DefaultTex[TEXTURE_x_INDEX]. The same should be done with the Current1D/2D/3D/etc pointers... (cherry picked from commit 4d24b639d160fe485a3e8f7395e7654538be29e0)
2009-03-13Fix an i965 assertion failure on glClear()Robert Ellison1-1/+1
While running conform with render-to-texture: conform -d 33 -v 2 -t -direct the i965 driver failed this assertion: intel_clear.c:77: intel_clear_tris: Assertion `(mask & ~((1 << BUFFER_BACK_LEFT) | (1 << BUFFER_FRONT_LEFT) | (1 << BUFFER_DEPTH) | (1 << BUFFER_STENCIL))) == 0' failed. The problem is that intel_clear_tris() is called by intelClear() to clear any and all of the available color buffers, but intel_clear_tris() actually only handles the back left and front left color buffers; so the assertion fails as soon as you try to clear a non-standard color buffer. The fix is to have intelClear() only call intel_clear_tris() with buffers that intel_clear_tris() can support. intelClear() already backs down to _swrast_Clear() for all buffers that aren't handled explicitly. (cherry picked from commit 0ccbc3c905f0594a35d72887a1f115e148aaa596)

2009-03-13intel: tell libdrm whether we want a cpu-ready or gpu-ready BO for regions.Eric Anholt7-13/+27
This lets us avoid allocing new buffers for renderbuffers, finalized miptrees, and PBO-uploaded textures when there's an unreferenced but still active one cached, while also avoiding CPU waits for batchbuffers and CPU-uploaded textures. The size of BOs allocated for a desktop running current GL cairogears on i915 is cut in half with this. Note that this means we require libdrm 2.4.5. (cherry picked from commit 40dd024be618d805b3744e15d25e115018641324)
2009-03-13i965: Fix render target read domains.Eric Anholt1-2/+1
We were asking for something illegal (write_domain != 0 && read_domains != write_domain) because at the time of writing the region surfaces were used for texturing occasionally as well, and we weren't really clear on the model GEM was going to use. This reliably triggered a kernel bug with domain handling, resulting in oglconform mustpass.c failure. Of course, it only became visible after 01bc4d441fd6821ad9fc20d5e9544e4e587e4ff0 cleaned up some gratuitous flushing. (cherry picked from commit 078e8a61b2aa547c6794f586a5c8bfaa575bb066)
