* gallium: Make TGSI_SEMANTIC_FOG register four-component wide.José Fonseca2013-11-212-12/+1
| | | | | | | | | | | | | | | | | | | | | | | D3D9 Shader Model 2 restricted the fog register to one component, http://msdn.microsoft.com/en-us/library/windows/desktop/bb172945.aspx , but that restriction no longer exists in Shader Model 3, and several WHCK tests enforce that. So this change: - lifts the single-component restriction TGSI_SEMANTIC_FOG from Gallium interface - updates the Mesa state tracker to enforce output fog has (f, 0, 0, 1) - draw module was updated to leave TGSI_SEMANTIC_FOG output registers alone Several gallium drivers that are going out of their way to clear TGSI_SEMANTIC_FOG components could be simplified in the future.

* u_gen_mipmap: Use untampered cubemap texture coords when generating mipmaps.José Fonseca2013-11-205-6/+19
| | | | | | | | | | | | | | | | | | | It's not necessary to scale down cubemap texture coords when generating mipmaps: we are doing a 2x minification therefore it's guaranteed that the texture coords will always be at least 1 texel away of the edges. Scaling down can actually be harmful, as it may cause artefacts when generating mipmaps with nearest filtering. Sample points will lie exactly in the middle each 2x2 texels, so the scaling factor was causing different texels to be take on each quadrant of the cube face. This is apparent with a 1x1 checkerboard pattern in the base mipmap level: instead of next mipmap level receiving a constant color throughout the face, it will have different colors for each quadrant of the face. The behaviour for blits is left untouched for now, but the cubemap texture coord scaling hack should be reconsidered eventually. Reviewed-by: Brian Paul <[email protected]>

* gallivm,llvmpipe: fix float->srgb conversion to handle NaNsRoland Scheidegger2013-11-144-26/+43
| | | | | | | | | | | | | | | | | | | | | | | | d3d10 requires us to convert NaNs to zero for any float->int conversion. We don't really do that but mostly seems to work. In particular I suspect the very common float->unorm8 path only really passes because it relies on sse2 pack intrinsics which just happen to work by luck for NaNs (float->int conversion in hw gives integer indeterminate value, which just happens to be -0x80000000 hence gets converted to zero in the end after pack intrinsics). However, float->srgb didn't get so lucky, because we need to clamp before blending and clamping resulted in NaN behavior being undefined (and actually got converted to 1.0 by clamping with sse2). Fix this by using a zero/one clamp with defined nan behavior as we can handle the NaN for free this way. I suspect there's more bugs lurking in this area (e.g. converting floats to snorm) as we don't really use defined NaN behavior everywhere but this seems to be good enough. While here respecify nan behavior modes a bit, in particular the return_second mode didn't really do what we wanted. From the caller's perspective, we really wanted to say we need the non-nan result, but we already know the second arg isn't a NaN. So we use this now instead, which means that cpu architectures which actually implement min/max by always returning non-nan (that is adhering to ieee754-2008 rules) don't need to bend over backwards for nothing.

* gallivm: optimize lp_build_minify for sseRoland Scheidegger2013-11-053-13/+54
| | | | | | | | | | | | | | | | | SSE can't handle true vector shifts (with variable shift count), so llvm is turning them into a mess of extracts, scalar shifts and inserts. It is however possible to emulate them in lp_build_minify with float muls, which should be way faster (saves over 20 instructions per 8-wide lp_build_minify). This wouldn't work for "generic" 32bit shifts though since we've got only 24bits of mantissa (actually for left shifts it would work by using sse41 int mul instead of float mul but not for right shifts). Note that this has very limited scope for now, since this is only used with per-pixel lod (otherwise we're avoiding the non-constant shift count by doing per-quad shifts manually), and only 1d textures even then (though the latter should change).

* gallivm: implement fully accurate corner filtering for seamless cube mapsRoland Scheidegger2013-10-251-13/+151
| | | | | | | | | | | | | | | | | | | | | | d3d10 requires that cube corners are filtered with accurate weights (that is, the weight of the non-existing corner texel should be evenly distributed to the other 3 texels). OpenGL does not require this (but recommends it). This requires us to use different filtering code, since we need per-texel weights which our 2d lerp doesn't (and can't) do. And of course the (now per element) weights need to be adjusted too for it to work. Invoke the new filtering code whenever there's an edge to keep things simpler, as it will work for edges too not just corners but of course it's only needed with corners. More ugly code for not much gain but at least a hacked up cubemap demo shows very nice corners now... Not sure yet if and how this should be configurable... v2: incorporate feedback from Jose, only use special corner filtering code when there's a corner not when there's only an edge (as corner filtering code is slower, though a perf difference was only measureable when always forcing edge code). Plus some minor style fixes. Reviewed-by: Jose Fonseca <[email protected]>

* gallivm: implement seamless cube filteringRoland Scheidegger2013-10-213-40/+368
| | | | | | | | | | | | | | | | | | | | | | | | | For seamless cube filtering it is necessary to determine new faces and new coords per sample. The logic for this is _seriously_ complex (what needs to happen is very "asymmetric" wrt face, x/y under/overflow), further complicated by the fact that if the 4 samples are in a corner (meaning we only have actually 3 samples, and all 3 are on different faces) then falling off the edge is happening _both_ on x and y axis simultaneously. There was a noticeable performance hit in mesa's cubemap demo when seamless filtering was forced on (just below 10 percent or so in a debug build, when disabling all filtering hacks, otherwise it would probably be a bit more) and when always doing the logic, hence use a branch which it only does it if any of the pixels in a quad (or in two quads) actually hit this. With that there was no measurable performance hit in the cubemap demo (neither in a debug nor release buidl), but this will vary (cubemap demo very rarely hits edges). Might also be different on other cpus, as this forces SoA sampling path which potentially can be quite a bit slower. Note that as for corners, this code gets all the 3 samples which actually exist right, and the 4th texel will simply be the same as one of the others, meaning that filter weights will be a bit wrong. This however should be enough for full OpenGL (but not d3d10) compliance. Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | | | | | | During the recent bind_sampler_states() interface change in gallium we changed the CSO single_sampler_done() function so that if we were decreasing the number of sampler states bound in the driver, we'd null-out the "extra/old" sampler states to unbind them. See commit 1e2fbf265. However, we didn't make the corresponding fix for sampler views. This caused an assertion to fail in the svga driver which checked that the number of sampler views matched the number of sampler states.

And use sign bit of major axis instead of pre-select s/t/r sign for coord mirroring (which should be the same in the end, saves 2 ands).
