* svga: emit sampler declarations in the helper function for non vgpu10Charmaine Lee2016-03-291-0/+4
| | | | | | | | | | | | | With commit dc9ecf58c0c5c8a97cd41362e78c2fcd9f6e3b80, we are now getting the sampler target from the sampler view declaration. But since a sampler view declaration can be defined after a sampler declaration, we need to emit the sampler declarations in the pre-helpers function, otherwise, the sampler target might not have defined yet for the sampler declaration. Fixes viewperf maya-03 and various gl trace regressions in hwv11. Reviewed-by: Brian Paul <[email protected]>
* svga: use shader sampler view declarationsBrian Paul2016-03-211-0/+2
| | | | | | | | | | | | | | Previously, we looked at the bound textures (via the pipe_sampler_views) to determine texture dimensions (1D/2D/3D/etc) and datatype (float vs. int). But this could fail in out of memory conditions. If we failed to allocate a texture and didn't create a pipe_sampler_view, we'd default to using 0 (PIPE_BUFFER) as the texture type. This led to device errors because of inconsistent shader code. This change relies on all TGSI shaders having an SVIEW declaration for each SAMP declaration. The previous patch series does that.

* svga: detect constant color writes in fragment shadersBrian Paul2015-10-221-0/+3
| | | | | | | | | | | | | | | | | | Examine the fragment shader to try to detect TGSI shaders which use "MOV OUT[0], CONST[i]" to write a constant value for the fragment color. In this case, all fragments will have the same color (unless blending is enabled). This is a common case for OpenGL code such as: glColor(), glBegin(), glVertex(), ..., glEnd() when lighting/fog/etc are disabled. In this case, the Mesa/gallium state tracker actually generates a simple "MOV OUT[0], CONST[i]" fragment shader. This will be used by the next commit to avoid provoking vertex conversion (creating/rewriting an index buffer) when drawing flat-shaded primitives.

* svga: implement support for signed byte vertex attributesBrian Paul2014-04-171-1/+1
| | | | | | | | | | | | | | There's no SVGA3D_DECLTYPE that directly corresponds to PIPE_FORMAT_R8G8B8_SNORM. Previously, we used the swtnl fallback path to handle this but that's slow and causes invariance issues. Now we fetch the attribute as SVGA3D_DECLTYPE_UBYTE4N and insert some extra VS instructions to remap the attributes from the range [0,1] to the range[-1,1]. Fixes Sauerbraten sw fallback. Fixes piglit normal3b3s-invariance test. Reviewed-by: Charmaine Lee <[email protected]>

| | | | | | | | | | | | Fixes glean fragProg1 regression caused by commit b9f68d927ea (implement TGSI_PROPERTY_FS_COLOR0_WRITES_ALL_CBUFS). This bug only appears when the fragment shader emits fragment.Z before color outputs. The bug was caused by confusion between register indexes and semantic indexes. Also added some comments to better explain register indexing. Reviewed-by: Jose Fonseca <[email protected]>

* svga: move temp register index assertionsBrian Paul2012-02-231-2/+6
| | | | | | | | | | | | | | The assertion recently added in dst_register() was invalid because that function is also (suprisingly) used to declare constant registers. Move the assertion to the callers where we're really creating temp registers and add some code to prevent emitting invalid temp register indexes for release builds. Also, update the comment for get_temp(). It didn't return -1 if it ran out of registers and none of the callers checked for that. Reviewed-by: Jose Fonseca <[email protected]>

* svga: implement generic variable index remappingBrian Paul2011-11-031-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | The state tracker may generate shaders that use generic vs outputs / fs inputs like: DCL IN[0], GENERIC[0] DCL IN[1], GENERIC[10] DCL IN[2], GENERIC[11] This patch remaps 0, 10, 11 to small integers like 1, 2, 3 so that we stay inside the SVGA3D limit (8). The remapping is done to both the vertex shader outputs and the fragment shader inputs. The same mapping must be used for a vs/fs pair. Note that 'union svga_compile_key' is now 'struct svga_compile_key' because we needed to add the register remapping table. The change in size isn't really significant though (it's not a search key). Also, add assertions when building up SVGA3D src/dst registers to we don't try to store too large of value for the bitfield size. Reviewed-by: José Fonseca <[email protected]>
