* svga: implement TGSI_OPCODE_ROUNDBrian Paul2012-07-051-15/+51
| | | | | | | ROUND and TRUNC are implemented with one function to reduce code duplication. Note: ROUND isn't actually used yet, but probably will be soon. Reviewed-by: José Fonseca <[email protected]>
* svga: fix CMP translation for vertex shadersBrian Paul2012-07-051-36/+37
| | | | | | | | | | Converting CMP to SLT+LRP didn't work when src2 or src3 was Inf/NaN. That's the case for GLSL sqrt(0). sqrt(0) actually happens in many piglit auto-generated tests that use the distance() function. v2: remove debug/devel code, per Jose Reviewed-by: José Fonseca <[email protected]>

* GLES2: upgrade gl2ext.h to version 18099Kristian Høgsberg2012-07-041-10/+0
| | | | | | | | | | | | | | | Redo this commit, and remove the inclusion of gl2ext.h from src/mapi/glapi/glapi_priv.h. The include was added in 8f3be339850ead96f9c6200db4e0db1f74e39d13 to fix a missing prototype for glDrawBuffersNV and others, but it's not possible to include both glext.h and gl2ext.h from the same file. I don't see the missing prototype here (with or without shared glapi) so I'm just removing the offending #include. Also, since we're redoing this, update to the most recent gl2ext.2.

* gallium/util: Save and restore vertex buffer state in util_gen_mipmap.Stuart Abercrombie2012-07-041-0/+2
| | | | | | | | | | | | | Calling glGenerateMipmap could overwrite vertex buffer state, leading to incorrect rendering or crashes depending on the Gallium driver. This was happening on WebGL Conformance test texture-size. Before 784dd51198433e5c299da4a7742c68d21d68d1c1 this was covered up by redundant vertex buffer validation.

* i965/fs: Allow copy propagation on uniforms.Eric Anholt2012-07-031-4/+7
| | | | | | | | | | | | | | | | | | This is a big win for savage2, hon and yofrankie. 62 new programs for savage2/hon get 16-wide mode, along with one for humus demos and two for tropics. Even a few shaders from tropics see reductions of 15% or more. total instructions in shared programs: 216536 -> 207353 (-4.24%) instructions in affected programs: 123941 -> 114758 (-7.41%) In benchmarking Tropics, only a .040% +/- 034% performance improvement was observed (n=90). Rather disappointing, but I was primarily motivated to do this patch by a regression in the number of 16-wide shaders compiled after a GRF texturing on IVB patch I'm working on. Hopefully this helps avoid that regression. Reviewed-by: Kenneth Graunke <[email protected]>
* i965/fs: Allow copy propagation with source modifiers.Eric Anholt2012-07-031-3/+17
| | | | | | | | | | | | | This shaves a few instructions off of a ton of programs. For 12 shaders from tropics and sanctuary, it's enough reduction in register pressure to get 16-wide mode. 7 shaders from heroes of newerth and savage2 are hurt by about 1.1%, where copy propagation of negates ends up preventing coalescing, but we could regain that by doing dataflow analysis in our copy propagation. No significant performance difference in tropics (n=11) Reviewed-by: Kenneth Graunke <[email protected]>

* msaa: Make meta-ops save and restore state of GL_MULTISAMPLE.Paul Berry2012-07-022-1/+17
| | | | | | | | | | | | | | | | | | | | | | The meta-ops _mesa_meta_Clear() and _mesa_meta_glsl_Clear() need to ignore the state of GL_SAMPLE_ALPHA_TO_COVERAGE, GL_SAMPLE_ALPHA_TO_ONE, GL_SAMPLE_COVERAGE, GL_SAMPLE_COVERAGE_VALUE, and GL_SAMPLE_COVERAGE_INVERT when clearing multisampled buffers. The easiest way to accomplish this is to disable GL_MULTISAMPLE during the clear meta-ops. Note: this patch also causes GL_MULTISAMPLE to be disabled during _mesa_meta_GenerateMipmap() and _mesa_meta_GetTexImage() (since those two meta-ops use MESA_META_ALL). Arguably this isn't strictly necessary, since those meta-ops use their own non-MSAA fbo's, but it shouldn't do any harm.

* i965/msaa: Fix centroid interpolation of unlit pixels.Paul Berry2012-07-024-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | From the Ivy Bridge PRM, Vol 2 Part 1 p280-281 (3DSTATE_WM: Barycentric Interpolation Mode): "Errata: When Centroid Barycentric mode is required, HW may produce incorrect interpolation results when a 2X2 pixels have unlit pixels." To work around this problem, after doing centroid interpolation, we replace the centroid-interpolated values for unlit pixels with non-centroid-interpolated values (which are interpolated at pixel centers). This produces correct rendering at the expense of a slight increase in shader execution time. I've conditioned the workaround with a runtime flag (brw->needs_unlit_centroid_workaround) in the hopes that we won't need it in future chip generations. Fixes piglit tests "EXT_framebuffer_multisample/interpolation {2,4} {centroid-deriv,centroid-deriv-disabled}". All MSAA interpolation tests pass now. Reviewed-by: Eric Anholt <[email protected]>
* i965/fs: Add FS_OPCODE_MOV_DISPATCH_TO_FLAGS to fragment shader backend.Paul Berry2012-07-024-2/+39
| | | | | | | | | | | | | | In order to compute centroid varyings correctly, the fragment shader needs to be able to load the current pixel/sample mask into a flag register. This patch adds an opcode to the fragment shader back-end to do this; the opcode gets translated into the instruction mov(1) f0<1>UW g1.14<0,1,0>UW { align1 WE_all } Since this instruction clobbers f0, instruction scheduling has to treat it the same as instructions that have a conditional modifier.

* glsl: Remove unused ir_loop_jump::loop pointer.Kenneth Graunke2012-07-021-4/+0
| | | | | | | | | | | | | | | | | Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also accidentally added a new pointer to the enclosing loop. Furthermore, it tried to initialize the new field by adding "this->loop = loop;" to the constructor, but since there is no loop parameter, this only initialized the field to itself---so it will likely be a garbage pointer. A lot of code, such as lower_jumps, allocates new loop jumps without setting this field appropriately, so any uses would probably just crash. Thankfully, there were none, so we can just delete the field.

* meta: Don't alter fragment color clamp in DrawPixels().Kenneth Graunke2012-07-021-1/+0
| | | | | | | | | | | | | | | | DrawPixels uses the MESA_META_CLAMP_FRAGMENT_COLOR flag to save/restore the fragment color clamp mode. This is unnecessary since it never alters it. It's also harmful: when the clamp mode is GL_FIXED_ONLY, setting this flag causes _mesa_meta_begin to force it to GL_FALSE, breaking clamping on SNORM formats. DrawPixels should use the user-specified clamp mode and not change it. Fixes Piglit's spec/ARB_color_buffer_float/GL_RGBA8_SNORM-drawpixels test on i965/Sandybridge (with SNORM render targets re-enabled).
