* draw,llvmpipe,util: add depth bias calculation for arb_depth_buffer_floatMatthew McClure2013-11-0714-56/+182
| | | | | | | | | | | | | | | With this patch, the llvmpipe and draw modules will calculate the depth bias according to floating point depth buffer semantics described in the arb_depth_buffer_float specification, when the driver has a z buffer bound with a format type of UTIL_FORMAT_TYPE_FLOAT. By default, the driver will use the existing UNORM calculation for depth bias. A new function, draw_set_zs_format, was added to calculate the Minimum Resolvable Depth value and floating point depth sense for the draw module.

* i965: Avoid flushing the batch for every blorp op.Eric Anholt2013-11-074-17/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | This brings over the batch-wrap-prevention and aperture space checking code from the normal brw_draw.c path, so that we don't need to flush the batch every time. There's a risk here if the intel_emit_post_sync_nonzero_flush() call isn't high enough up in the state emit sequences -- before, we implicitly had one at the batch flush before any state was emitted, so Mesa's workaround emits didn't really matter. Since the SNB fixes by Ken, I didn't see any regressions after 3 piglit runs. Improves cairo-gl performance by 13.7733% +/- 1.74876% (n=30/32) Improves minecraft apitrace performance by 1.03183% +/- 0.482297% (n=90). Reduces low-resolution GLB 2.7 performance by 1.17553% +/- 0.432263% (n=88) Reduces Lightsmark performance by 3.70246% +/- 0.322432% (n=126) No statistically significant performance difference on unigine tropics (n=10) No statistically significant performance difference on openarena (n=755) The two apps that are hurt happen to include stalls on busy buffer objects, so I think this is an effect of missing out on an opportune flush.

* i965: Use has_surface_tile_offset in depth/stencil alignment workaround.Kenneth Graunke2013-11-071-2/+2
| | | | | | | | | | | | | Currently, has_surface_tile_offset is equivalent to gen == 4 && !is_g4x. We already use it for related checks in brw_wm_surface_state.c, so it makes sense to use it here too. It's simpler and more future-proof. Broadwell also lacks surface tile offsets. With this patch, I won't need to update any generation checking; I can simply not set the flag. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* 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).
