* i965: Add a driconf option to disable GL_ARB_blend_func_extended.Kenneth Graunke2012-07-194-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unigine Heaven (at least) has a bug where it incorrectly uses the GL_ARB_blend_func_extended extension. Dual source blending allows two color outputs per render target; individual shader outputs can be assigned to be either the first or second blending input by setting the 'index' via one of two methods: - An API call: glBindFragDataLocationIndexed() - The GLSL 'layout' qualifier provided by GL_ARB_explicit_attrib_location Both of these only work on user defined fragment shader outputs; it's an error to use either on built-in outputs like gl_FragData. Unigine uses gl_FragData and gl_FragColor exclusively, and doesn't even attempt to use either method to set index == 1. However, it does set the blending function to SRC1 enums, which requires a fragment shader output with index == 1 or else rendering is undefined. In other words, enabling ARB_blend_func_extended causes Unigine to render incorrectly, resulting in an apparent regression, even though our driver code (as far as I can tell) is perfectly fine.

* r600g: setup streamout before calling last r600_need_cs_space before drawingMarek Olšák2012-07-181-6/+6
| | | | | This fixes CS checker errors due to registers not being initialized, because the flush occured after dirty state was emitted but before drawing.
* i965/fs: Make register spill/unspill only do the regs for that instruction.Eric Anholt2012-07-181-33/+33
| | | | | | | | | | | | | | | | | | Previously, if we were spilling the result of a texture call, we would store all 4 regs, then for each use of one of those regs as the source of an instruction, we would unspill all 4 regs even though only one was needed. In both lightsmark and l4d2 with my current graphics config, the shaders that produce spilling do so on split GRFs, so this doesn't help them out. However, in a capture of the l4d2 shaders with a different snapshot and playing the game instead of using a demo, it reduced one shader from 2817 instructions to 2179, due to choosing a now-cheaper texture result to spill instead of piles of texcoords. v2: Fix comment noted by Ken, and fix the if condition associated with it for the current state of what constitutes a partial write of the destination.

* i965/fs.h: Refactor tests for instructions modifying a register.Eric Anholt2012-07-184-34/+16
| | | | | | | | | | There's one instance of a potential behavior change: propagate_constants may now propagate into a part of a vgrf after a different part of it was overwritten by a send that returns multiple registers. I don't think we ever generate IR that meets that condition, but it's something to note if we bisect behavior change to this. Reviewed-by: Kenneth Graunke <[email protected]>
* i965/fs: Replace usage is_tex() with regs_written() checks.Eric Anholt2012-07-181-9/+9
| | | | | | | | | | In these places, we care about any sort of send that hits more than one reg, not just textures. We don't yet have anything else returning more than one reg, so there's no change. v2: Use mlen instead of is_tex() for the is-it-a-send check. Reviewed-by: Kenneth Graunke <[email protected]>

* softpipe: Take all lods into account when texture sampling.Olivier Galibert2012-07-182-766/+645
| | | | | | | | | | | | This patch churns a lot because it needs to change 4-wide filters into single pixel filters, since each fragment may use a different filter. The only case not entirely supported is the anisotropic filtering. Not sure what we want to do there, since a full quad is required by that filter.

| | | | | | | | | | | | | | | | | | | | | From the GL 3.0 spec, section 4.3.3, in the documentation for CopyPixels(): "An INVALID_OPERATION error will be generated if the object bound to READ_FRAMEBUFFER_BINDING is framebuffer complete and the value of SAMPLE_BUFFERS is greater than zero." The same applies to CopyTexImage...() and CopyTexSubImage...() functions, since they are defined in terms of CopyPixels(). Previously we were generating an INVALID_FRAMEBUFFER_OPERATION error in these cases. Fixes piglit tests "EXT_framebuffer_multisample/negative-{copypixels,copyteximage}".

| | | | | | | | | | | | | | | Issues fixed: - set_vs_sampler_views for evergreen is now properly implemented. - Added the missing inval_texture_cache call for evergreen. - have_depth_texture was sometimes incorrectly set to false on evergreen even if there were depth textures in other shader stages. To fix this, set it to true once and never set it to false again. It's stupid, but it matches the r600 code. The proper fix is left to another patch. - Optimizaton: The sampler views which aren't changed aren't updated.
