* mesa/shader: return correct attribute location for double matrix arraysDave Airlie2015-12-111-3/+8
| | | | | | | | | | | | | | | | | | | If we have a dmat2[4], then dmat2[0] is at 17, dmat2[1] at 19, dmat2[2] at 21 etc. The old code was returning 17,18,19. I think this code is also wrong for float matricies as well. There is now a piglit for the float case. This partly fixes: GL41-CTS.vertex_attrib_64bit.limits_test [airlied: update with Tapani suggestion to clean it up].

* draw: fix clipping with linear interpolated values and gl_ClipVertexRoland Scheidegger2015-12-111-4/+4
| | | | | | | | | | | | | | | | Discovered this when working on other clip code, apparently didn't work correctly - the combination of linear interpolated values and using gl_ClipVertex produced wrong values (failing all such combinations in piglits glsl-1.30 interpolation tests, named interpolation-noperspective-XXX-vertex). Use the pre-clip-pos values when determining the interpolation factor to fix this. Noone really understands this code well, but everybody agrees this looks sane... This fixes all those failing tests (10 in total) both with the llvm and non-llvm draw paths, with no piglit regressions.

* nir: Get rid of *_indirect variants of input/output load/store intrinsicsJason Ekstrand2015-12-1019-414/+391
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is some special-casing needed in a competent back-end. However, they can do their special-casing easily enough based on whether or not the offset is a constant. In the mean time, having the *_indirect variants adds special cases a number of places where they don't need to be and, in general, only complicates things. To complicate matters, NIR had no way to convdert an indirect load/store to a direct one in the case that the indirect was a constant so we would still not really get what the back-ends wanted. The best solution seems to be to get rid of the *_indirect variants entirely. This commit is a bunch of different changes squashed together: - nir: Get rid of *_indirect variants of input/output load/store intrinsics - nir/glsl: Stop handling UBO/SSBO load/stores differently depending on indirect - nir/lower_io: Get rid of load/store_foo_indirect - i965/fs: Get rid of load/store_foo_indirect - i965/vec4: Get rid of load/store_foo_indirect - tgsi_to_nir: Get rid of load/store_foo_indirect - ir3/nir: Use the new unified io intrinsics - vc4: Do all uniform loads with byte offsets - vc4/nir: Use the new unified io intrinsics - vc4: Fix load_user_clip_plane crash - vc4: add missing src for store outputs - vc4: Fix state uniforms - nir/lower_clip: Update to the new load/store intrinsics - nir/lower_two_sided_color: Update to the new load intrinsic NIR and i965 changes are Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> NIR indirect declarations and vc4 changes are Reviewed-by: Eric Anholt <eric@anholt.net> ir3 changes are Reviewed-by: Rob Clark <robdclark@gmail.com> NIR changes are Acked-by: Rob Clark <robdclark@gmail.com>

* gallium/util: return correct number of bound vertex buffersPatrick Rudolph2015-12-101-1/+7
| | | | | | | | | | | | | | | | | | | | In case a state tracker unbinds every slot by a seperate pipe->set_vertex_buffers() call, starting from slot zero, the number of bound buffers would not reach zero at all. The current algorithm does not account for pre-existing holes in the buffer list. Unbinding all buffers at once or starting at the top-most slot results in correct behaviour. Calculating the correct number of bound buffers fixes a NULL pointer dereference in nvc0_validate_vertex_buffers_shared().

* blit: Don't take into account the Mesa format when checking MSRT blitNeil Roberts2015-12-101-13/+15
| | | | | | | | | | | | | | | | | | | | | | According to the GLES3 spec, blitting between multisample FBOs with different internal formats should not be allowed. The compatible_resolve_formats function implements this check. Previously it had a shortcut where if the Mesa formats of the two renderbuffers were the same then it would assume the blit is ok. However some drivers map different internal formats to the same Mesa format, for example it might implement both GL_RGB and GL_RGBA textures with MESA_FORMAT_R8G8B8A_UNORM. The function is used to generate a GL error according to what the GL spec requires so the blit should not be allowed in that case. This patch just removes the shortcut so that it only ever looks at the internal format. Note that I posted a related patch to disable this check altogether for desktop GL. However this function is still used on GLES3 because there are conformance tests that require this behaviour so this patch is still useful.

* i965: Check base format to determine whether to use tiled memcpyNeil Roberts2015-12-102-6/+8
| | | | | | | | | | | | | The tiled memcpy doesn't work for copying from RGBX to RGBA because it doesn't override the alpha component to 1.0. Commit 2cebaac479d4 added a check to disable it for RGBX formats by looking at the TexFormat. However a lot of the rest of the code base is written with the assumption that an RGBA texture can be used internally to implement a GL_RGB texture. If that is done then this check breaks. This patch makes it instead check the base format of the texture which I think more directly matches the intention. Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com>

| | | | | | | | | Since Gen8 this is allowed as a rendering target so we don't need to override it to B8G8R8A8. This is helpful on Gen9+ where using this override causes fast clears not to work. Reviewed-by: Anuj Phogat <anuj.phogat@gmail.com> Reviewed-by: Ben Widawsky <benjamin.widawsky@intel.com>
* i965/gen9: Allow fast clear for MSRT formats matching renderNeil Roberts2015-12-101-4/+11
| | | | | | | | | | | | | | | | | Previously fast clear was disallowed on Gen9 for MSRTs with the claim that some formats don't work but we didn't understand why. On further investigation it seems the formats that don't work are the ones where the render surface format is being overriden to a different format than the one used for texturing. The one used for texturing is not actually a renderable format. It arguably makes sense that the sampler hardware doesn't handle the fast color correctly in these cases because it shouldn't be possible to end up with a fast cleared surface that is non-renderable. This patch changes the limitation to prevent fast clear for surfaces where the format for rendering is overriden. Reviewed-by: Ben Widawsky <benjamin.widawsky@intel.com>
* i965/gen9/fast-clear: Handle linear→SRGB conversionNeil Roberts2015-12-101-0/+11
| | | | | | | | | | | | | | | If GL_FRAMEBUFFER_SRGB is enabled when writing to an SRGB-capable framebuffer then the color will be converted from linear to SRGB before being written. There is no chance for the hardware to do this itself because it can't modify the clear color that is programmed in the surface state so it seems pretty clear that the driver should be handling this itself. Note that this wasn't a problem before Gen9 because previously we were only able to do fast clears to 0 or 1 and those values are the same in linear and SRGB space.
