* gallivm: change cubemaps / derivatives handling, take 55Roland Scheidegger2013-04-183-104/+119
| | | | | | | | | | | | | | | | | | | | | | | Turns out the previous "fix" for handling per-pixel face selection and derivatives didn't work out that well - the derivatives were wrong by quite a bit, in theory transformation of the derivatives into cube space should work, but would be _a lot_ more work than the "simplified" transform used. So, for explicit derivatives, I'm just giving up and go back to not honoring them. For implicit derivatives (and the fake explicit ones) however we try something a little different, we just calculate rho as we would for a 3d texture, that is after scaling the coords by the inverse major axis. This gives the same results as calculating the derivs after projection of the coords to the same face as long as all pixels hit the same face (and only without rho_no_opt, otherwise it should be a bit worse). And when not all pixels are hitting the same face, the results aren't so hot but not catastrophically bad (I believe not off by more than a factor of 2 without no_rho_approx and not more than sqrt(2) with no_rho_approx). I think this is better than just picking the wrong face but who knows... Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>
* gallivm: Add no_rho_approx debug optionRoland Scheidegger2013-04-183-118/+185
| | | | | | | | | | | | | | | | | | | | | This will calculate rho correctly as sqrt(max((ds/dx)^2 + (dt/dx)^2 + (dr/dx)^2), (ds/dx)^2 + (dt/dx)^2 + (dr/dx)^2)) instead of max(|ds/dx|,|dt/dx|,|dr/dx|,|ds/dy|,|dt/dy,|dr/dy|) (for 3 coords - 2 coords work analogous, for 1 coord there's no point doing the exact version), for both implicit and explicit derivatives. While such approximation seems to be allowed in OpenGL some APIs may be less forgiving, and the error can be quite large (sqrt(2) for 2 coords, sqrt(3) for 3 coords so wrong by nearly one mip level in the latter case). This also helps to single out "real" bugs from "expected" ones, so it is debug only (though at least combined with no_brilinear I didn't really see much of a performance difference but only tested with a debug build - at least with implicit mipmaps the instruction count is almost exactly the same though the instructions are more complex (1 sqrt and mul/adds instead of and/max mostly). The code when the option isn't set stays exactly the same. v2: rename no_rho_opt to no_rho_approx. Reviewed-by: Brian Paul <[email protected]>

* i965/vec4: Fix hypothetical use of uninitialized data in attribute_map[].Paul Berry2013-04-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes issue identified by Klocwork analysis: 'attribute_map' array elements might be used uninitialized in this function (vec4_visitor::lower_attributes_to_hw_regs). The attribute_map array contains the mapping from shader input attributes to the hardware registers they are stored in. vec4_vs_visitor::setup_attributes() only populates elements of this array which, according to core Mesa, are actually used by the shader. Therefore, when vec4_visitor::lower_attributes_to_hw_regs() accesses the array to lower a register access in the shader, it should in principle only access elements of attribute_map that contain valid data. However, if a bug ever caused the driver back-end to access an input that was not flagged as used by core Mesa, then lower_attributes_to_hw_regs() would access uninitialized memory, which could cause illegal instructions to get generated, resulting in a possible GPU hang. This patch makes the situation more robust by using memset() to pre-initialize the attribute_map array to zero, so that if such a bug ever occurred, lower_attributes_to_hw_regs() would generate a (mostly) harmless access to r0. In addition, it adds assertions to lower_attributes_to_hw_regs() so that if we do have such a bug, we're likely to discover it quickly. Reviewed-by: Jordan Justen <[email protected]>

* draw/gs: make sure geometry shaders don't overflowZack Rusin2013-04-165-11/+81
| | | | | | | | | | | | | | The specification says that the geometry shader should exit if the number of emitted vertices is bigger or equal to max_output_vertices and we can't do that because we're running in the SoA mode, which means that our storing routines will keep getting called on channels that have overflown (even though they will be masked out, but we just can't skip them). So we need some scratch area where we can keep writing the overflown vertices without overwriting anything important or crashing.

* gallivm/gs: fix the end primitive callsZack Rusin2013-04-162-27/+50
| | | | | | | | | | | | | | | The issue with SOA execution and end_primitive opcode is that it can be executed both when we haven't emitted any vertices, in which case we don't want to emit an empty primitive, and when the execution mask is zero and the execution should be skipped. We handled only the latter of those conditions. Now we're combining the execution mask with a mask created from emitted vertices to handle both cases. As a result we don't need the pending_end_primitive flag which was broken because it was static and could be affected by both above mentioned conditions at run-time.
