* i965: Reduce code duplication in handling of depth, stencil, and HiZ.Paul Berry2013-04-025-151/+178
| | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates duplicate code in the brw_depthbuffer and gen7_depthbuffer state atoms. Previously, these state atoms contained 5 chunks of code for emitting the _3DSTATE_DEPTH_BUFFER packet (3 for Gen4-6 and 2 for Gen7). Also a lot of logic for determining the appropriate buffer setup was duplicated between the Gen4-6 and Gen7 functions. This refactor splits the code into three separate functions: brw_emit_depthbuffer(), which determines the appropriate buffer setup in a mostly generation-independent way, brw_emit_depth_stencil_hiz(), which emits the appropriate state packets for Gen4-6, and gen7_emit_depth_stencil_hiz(), which emits the appropriate state packets for Gen7. Tested using Piglit on Gen5-7 (no regressions). v2: Re-word some comments. Fix an assertion that incorrectly prohibited packed depth/stencil formats on Gen6 (these are allowed provided that HiZ is disabled).

* Revert "glsl: Replace constant-index vector array accesses with swizzles"Paul Berry2013-04-022-83/+83
| | | | | | | This reverts commit dbf94d105a48b7aafb2c8cf64d8b4392d87efea1, which was working around a bug in the handling of array indexing when constant folding built-in functions. Now that the constant folding bug has been fixed, the workaround is no longer needed.
* glsl: Fix array indexing when constant folding built-in functions.Paul Berry2013-04-021-1/+1
| | | | | | | | | | | | | | | | | | | Mesa constant-folds built-in functions by using a miniature GLSL interpreter (see ir_function_signature::constant_expression_evaluate_expression_list()). This interpreter had a bug in its handling of array indexing, which caused expressions like "m[i][j]" (where m is a matrix) to be handled incorrectly. Specifically, it incorrectly treated j as indexing into the whole matrix (rather than indexing just into the vector m[i]); as a result the offset computed for m[i] was lost and m[i][j] was treated as m[j][0]. Fixes piglit tests inverse-mat[234].{vert,frag}. NOTE: This is a candidate for the 9.1 and 9.0 branches.

| | | | | | | | | | | | | Conceptually the same as previously done in float_to_half. Should cut down number of instructions from 14 to 10 or so, but will promote some NaNs to Infs, so it's disabled. It gets a bit tricky though handling all the cases correctly... Passes basic tests either way (though there are no tests testing special cases, but some manual tests injecting them seemed promising). v2: style and comment fixes suggested by Jose Reviewed-by: Jose Fonseca <[email protected]>
* gallivm: consolidate code for float-to-half and float-to-packed conversion.Roland Scheidegger2013-04-023-108/+102
| | | | | | | | | | | | | | | | | | This replaces the existing float-to-half implementation. There are definitely a couple of differences - the old implementation had unspecified(?) rounding behavior, and could at least in theory construct Inf values out of NaNs. NaNs and Infs should now always be properly propagated, and rounding behavior is now towards zero (note this means too large but non-Infinity values get propagated to max representable value, not Infinity). The implementation will definitely not match util code, however (which does nearest rounding, which also means too large values will get propagated to Infinity). Also fix a bogus round mask probably leading to rounding bugs... v2: fix a logic bug in handling infs/nans. Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | | | | | | | | | | | | Like we have done for the VS and for constant-index uniform loads, we use the sampler engine to get caching in front of the L3 to avoid tickling the IVB L3 bug. This is also a bit of a functional change, as we're now loading a vec4 instead of a single dword, though we're not taking advantage of the other 3 components of the vec4 (yet). With the driver hacked to always take the varying-index path for all uniforms, improves performance of my old GLSL demo by 315% +/- 2% (n=4).

| | | | | | | | | | | | | | | | | We want to load vec4s, since loading a vec4 instead of a dword is basically no increased latency. But for variable indexed access, the previous requirement of aligned vec4s for a sampler LD was hard to implement. Note that this change only affects those messages that use the surface format, like sampler LDs, but not to the untyped data cache loads we've used in other cases.
