* i965/fs: The barrier send uses only 1 payload registerJordan Justen2015-09-152-2/+5
| | | | | | | | | | | | | | | | | | | When preparing the barrier payload, the instructions should operate in simd8 mode since we only use 1 payload register. fs_inst::regs_read is also updated to indicate that it only reads one register for SHADER_OPCODE_BARRIER.

* nir/lower_vec_to_movs: Coalesce into destinations of fdot instructionsJason Ekstrand2015-09-151-13/+36
| | | | | | | | | | | | | | | | | | | Now that we have a replicating fdot instruction, we can actually coalesce into the destinations of vec4 instructions. We couldn't really do this before because, if the destination had to end up in .z, we couldn't reswizzle the instruction. With a replicated destination, the result ends up in all channels so we can just set the writemask and we're done. Shader-db results for vec4 programs on Haswell: total instructions in shared programs: 1747753 -> 1746280 (-0.08%) instructions in affected programs: 143274 -> 141801 (-1.03%) helped: 667 HURT: 0 It turns out that dot-products matter...

| | | | | | | | | | | | | | | | | | | The old pass blindly inserted a bunch of moves into the shader with no concern for whether or not it was really needed. This adds code to try and coalesce into the destination of the instruction providing the value.

* nir/lower_vec_to_movs: Get rid of start_idx and swizzle compactingJason Ekstrand2015-09-151-20/+13
| | | | | | | | | | | | | Previously, we did this thing with keeping track of a separate start_idx which was different from the iteration variable. I think this was a relic of the way that GLSL IR implements writemasks. In NIR, if a given bit in the writemask is unset then that channel is just "unused", not missing. In particular, a vec4 operation with a writemask of 0xd will use sources 0, 2, and 3 and leave source 1 alone. We can simplify things a good deal (and make them correct) by removing this "compacting" step. Reviewed-by: Eduardo Lima Mitev <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | We made this switch in the FS backend some time ago and it seems to make a number of things a bit easier. In particular, supporting SSA values takes very little work in the backend and allows us to take advantage of the majority of the SSA information even after we've gotten rid of Phi nodes.

* i965/fs_surface_builder: Only apply predicate to components that existJason Ekstrand2015-09-151-1/+1
| | | | | | | | | | | | In certain conditions, we have to do bounds-checking in the shader for image_load_store. The way this works for image loads is that we do a predicated load and then emit a series of selects, one per component, that gives us 0 or the loaded value depending on whether or not you're in bounds. However, we were hard-coding 4 components which may not be correct. Instead, we should be using size which is the number of components read. Reviewed-by: Francisco Jerez <[email protected]>

| | | | | | | | | | | | | | | | | | | | | At the moment if a gbm buffer is imported and the gbm buffer has an old-style GBM_BO_FORMAT format, the import will crash, since it's passed directly to DRI functions that expect a fourcc format (as provided by the newer GBM_FORMAT definitions) This commit addresses the problem in two ways: 1) it prevents invalid formats from leading to a crash by returning EINVAL if the image couldn't be created 2) it translates GBM_BO_FORMAT formats into the comparable GBM_FORMAT formats.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the compute shader code around in order to make the way the code is split up more consistent. There should be no functional changes. Typically we have a few files per stage: brw_vs.c, brw_wm.c brw_gs.c: code to drive code generation and implement precompiling and cache search. genX_<stage>_state.c gen specific implementation of the state emission for the shader stage. The brw_*_emit() functions are all in the same files as the visitor classes they use (with the exception of VS, which may use either vec4 or fs). To make compute follow this convention, we move the brw_cs_emit() function into brw_fs.cpp. We can then rename brw_cs.cpp to brw_cs.c and do this in C like the other similar files. Finally, move state setup and atoms to gen7_cs_state.c.

* i965/vec4: Fix saturation errors when coalescing registersAntia Puentes2015-09-141-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the register types do not match and the instruction that contains the final destination is saturated, register coalescing generated non-equivalent code. This did not happen when using IR because types usually matched, but it is visible in nir-vec4. For example, mov vgrf7:D vgrf2:D mov.sat m4:F vgrf7:F is coalesced to: mov.sat m4:D vgrf2:D The patch prevents coalescing in such scenario, unless the instruction we want to coalesce into is a MOV (without type conversion implied). In that case, the patch sets the register types to the type of the final destination. Shader-db results in HSW (only vec4 instructions shown): total instructions in shared programs: 1754415 -> 1754416 (0.00%) instructions in affected programs: 74 -> 75 (1.35%) helped: 0 HURT: 1 GAINED: 0 LOST: 0 Only one extra instruction in one of the shaders, that comes from eliminating a saturation error by preventing register coalesce.
