* st/mesa: optionally apply texture swizzle to border color v2Christoph Bumiller2013-04-184-4/+30
| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap. The dependency of update_sampler on the texture updates was introduced to avoid doing the apply_depthmode to the swizzle twice. v2: Moved swizzling helper to u_format.c, extended the CAP to provide more accurate information.

* gallium: Disambiguate TGSI_OPCODE_IF.José Fonseca2013-04-172-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_IF condition had two possible interpretations: - src.x != 0.0f - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was false either for vertex and fragment shaders - gallivm/llvmpipe - postprocess - vl state tracker - vega state tracker - most old drivers - old internal state trackers - many graw examples - src.x != 0U - Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was true for both vertex and fragment shaders - tgsi_exec/softpipe - r600 - radeonsi - nv50 And drivers that use draw module also were a mess (because Mesa would emit float IFs, but draw module supports native integers so it would interpret IF arg as integers...) This sort of works if the source argument is limited to float +0.0f or +1.0f, integer 0, but would fail if source is float -0.0f, or integer in the float NaN range. It could also fail if source is integer 1, and hardware flushes denormalized numbers to zero. But with this change there are now two opcodes, IF and UIF, with clear meaning. Drivers that do not support native integers do not need to worry about UIF. However, for backwards compatibility with old state trackers and examples, it is advisable that native integer capable drivers also support the float IF opcode. I tried to implement this for r600 and radeonsi based on the surrounding code. I couldn't do this for nouveau, so I just shunted IF/UIF together, which matches the current behavior. Reviewed-by: Roland Scheidegger <[email protected]> Reviewed-by: Marek Olšák <[email protected]> v2: - Incorporate Roland's feedback. - Fix r600_shader.c merge conflict. - Fix typo in radeon, spotted by Michel Dänzer. - Incorporte Christoph Bumiller's patch to handle TGSI_OPCODE_IF(float) properly in nv50/ir.
* st/mesa: add support for ARB_texture_multisample (v3)Dave Airlie2013-04-1112-20/+96
| | | | | | | | | | | | | | | | This adds support to the mesa state tracker for ARB_texture_multisample. hardware doesn't seem to use a different texture instructions, so I don't think we need to create one for TGSI at this time. Thanks to Marek for fixes to sample number picking. v2: idr pointed out a bug in how we picked the max sample counts, use new internal format chooser interface to pick proper answers. v3: use st_choose_format directly, it was okay, fix anding of masks.

* mesa: allow internalformat_query with multisample texture targetsChris Forbes2013-03-242-4/+6
| | | | | | | | | | | | | | | | Now that we support ARB_texture_multisample, there are multiple targets accepted for this query, and they may have target-dependent limits, so pass the target to the driverfunc. For example, the sampling hardware may not be able to do general texelFetch() for some format/sample count combination, but the driver may still be able to implement a reasonable resolve operation, so it can be supported for renderbuffers.

* glsl: Convert mix() to use a new ir_triop_lrp opcode.Kenneth Graunke2013-02-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Many GPUs have an instruction to do linear interpolation which is more efficient than simply performing the algebra necessary (two multiplies, an add, and a subtract). Pattern matching or peepholing this is more desirable, but can be tricky. By using an opcode, we can at least make shaders which use the mix() built-in get the more efficient behavior. Currently, all consumers lower ir_triop_lrp. Subsequent patches will actually generate different code. v2 [mattst88]: - Add LRP_TO_ARITH flag to ir_to_mesa.cpp. Will be removed in a subsequent patch and ir_triop_lrp translated directly. v3 [mattst88]: - Move changes from the next patch to opt_algebraic.cpp to accept 3-src operations.
