* winsys/radeon: add command stream replay dump for faulty lockup v3Jerome Glisse2013-04-057-37/+443
| | | | | | | | | | | | | | | | | | Build time option, set RADEON_CS_DUMP_ON_LOCKUP to 1 in radeon_drm_cs.h to enable it. When enabled after each cs submission the code will try to detect lockup by waiting on one of the buffer of the cs to become idle, after a timeout it will consider that the cs triggered a lockup and will write a radeon_lockup.c file in current directory that have all information for replaying the cs. To build this file : gcc -O0 -g radeon_lockup.c -ldrm -o radeon_lockup -I/usr/include/libdrm v2: Add radeon_ctx.h file to mesa git tree v3: Slightly improve dumped file for easier editing, only dump first faulty cs Signed-off-by: Jerome Glisse <[email protected]>

* glsl: Add an optimization pass to flatten simple nested if blocks.Kenneth Graunke2013-04-044-0/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLBenchmark 2.7's shaders contain conditional blocks like: if (x) { if (y) { ... } } where the outer conditional's then clause contains exactly one statement (the nested if) and there are no else clauses. This can easily be optimized into: if (x && y) { ... } This saves a few instructions in GLBenchmark 2.7: total instructions in shared programs: 11833 -> 11649 (-1.55%) instructions in affected programs: 8234 -> 8050 (-2.23%) It also helps CS:GO slightly (-0.05%/-0.22%). More importantly, however, it simplifies the control flow graph, which could enable other optimizations.

* i965: Remove fixed-function texture projection avoidance optimization.Kenneth Graunke2013-04-041-25/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This optimization attempts to avoid extra attribute interpolation instructions for texture coordinates where the W-component is 1.0. Unfortunately, it requires a lot of complexity: the brw_wm_input_sizes state atom (all the brw_vs_constval.c code) needs to run on each draw. It computes the input_size_masks array, then uses that to compute proj_attrib_mask. Differences in proj_attrib_mask can cause state-dependent fragment shader recompiles. We also often fail to guess proj_attrib_mask for the fragment shader precompile, causing us to needlessly compile it twice. Furthermore, this optimization only applies to fixed-function programs; it does not help modern GLSL-based programs at all. Generally, older fixed-function programs run fine on modern hardware anyway. The optimization has existed in some form since the initial commit. When we rewrote the fragment shader backend, we dropped it for a while. Eric readded it in commit eb30820f268608cf451da32de69723036dddbc62 as part of an attempt to cure a ~1% performance regression caused by converting the fixed-function fragment shader generation code from Mesa IR to GLSL IR. However, no performance data was included in the commit message, so it's unclear whether or not it was successful. Time has passed, so I decided to re-measure this. Surprisingly, Eric's OpenArena timedemo actually runs /faster/ after removing this and the brw_wm_input_sizes atom. On Ivybridge at 1024x768, I measured a 1.39532% +/- 0.91833% increase in FPS (n = 55). On Ironlake, there was no statistically significant difference (n = 37).

* gallivm: some minor cube map cleanupRoland Scheidegger2013-04-041-10/+15
| | | | | | | | | | | | | | | The ar_ge_as_at variable was just very very confusing since the condition was actually the other way around (as_at_ge_ar). So change the condition (and the selects depending on it) to match the variable name. And also change the chosen major axis in case the coord values are the same. OpenGL doesn't care one bit which one is chosen in this case but it looks like dx10 would require z chosen over y, and y chosen over x (previously did x chosen over y, y chosen over z). Since it's all the same effort just honor dx10's wishes. (Though actually, for some prefered orderings, we could save one (or two with derivatives) selects since the tnewx and tnewz (and the corresponding dmax values) are the same.)

* gallivm: do per-pixel cube face selection (finally!!!)Roland Scheidegger2013-04-043-82/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This proved to be tricky, the problem is that after selection/mirroring we cannot calculate reasonable derivatives (if not all pixels in a quad end up on the same face the derivatives could get "randomly" exceedingly large). However, it is actually quite easy to simply calculate the derivatives before selection/mirroring and then transform them similar to the cube coordinates (they only need selection/projection, but not mirroring as we're not interested in the sign bit, of course). While there is a tiny bit more work to do (need to calculate derivs for 3 coords instead of 2, and additional selects) it also simplifies things somewhat for the coord selection itself (as we save some broadcast aos shuffles, and we don't need to calculate the average vector) - hence if derivatives aren't needed this should actually be faster. Also, this has the benefit that this will (trivially) work for explicit derivatives too, which we completely ignored before that (will be in a separate commit for better trackability). Note that while the way for getting rho looks very different, it should result in "nearly" the same values as before (the "nearly" is only because before the code would choose the face based on an "average" vector and hence the derivatives calculated according to this face, where now (for implicit derivatives) the derivatives are projected on the face selected for the first (top-left) pixel in a quad, so not necessarly the same face). The transformation done might not quite be state-of-the-art, calculating length(dx,dy) as max(dx,dy) certainly isn't neither but this stays the same as before (that is I think a better transform would _somehow_ take the "derivative major axis" into account so that derivative changes in the major axis wouldn't get ignored). Should solve some accuracy problems with cubemaps (can easily be seen with the cubemap demo when switching wrapping/filtering), though we still don't do seamless filtering to fix it completely (so not per-sample but per-pixel is certainly better than per-quad and already sufficient for accurate results with nearest tex filter). As for performance, it seems to be a tiny bit faster too (maybe 3% or so with cubemap demo). Which I'd have expected with nearest/nearest filtering where this will be less instructions, but the difference seems to actually be larger with linear/linear_mipmap_linear where it is slightly more instructions, probably the code appears less serialized allowing better scheduling (on a sandy bridge cpu). It actually seems to be now at least as fast as the old path using a conditional when using 128bit vectors too (that is probably more a result of testing with a newer cpu though), for now that old path is still there but unused. No piglit regressions. Reviewed-by: Jose Fonseca <[email protected]>
