* i965/vec4: Use nir_move_vec_src_uses_to_destJason Ekstrand2015-09-171-0/+3
| | | | | | | | | | | | | | | | | | | The idea here is not that it gives register coalescing a little bit of a helping hand. It doesn't actually fix the coalescing problems, but it seems to help a good bit. Shader-db results for vec4 programs on Haswell: total instructions in shared programs: 1746280 -> 1683959 (-3.57%) instructions in affected programs: 1259166 -> 1196845 (-4.95%) helped: 11363 HURT: 148 v2 (Jason Ekstrand): - Run nir_move_vec_src_uses_to_dest after going out of SSA - New shader-db numbers Reviewed-by: Eduardo Lima Mitev <[email protected]>
* mesa: Fix texture compression on big-endian systemsUlrich Weigand2015-09-174-7/+14
| | | | | | | | | | | | | | | | | | | | | | | Various pieces of code to create compressed textures will first generate an uncompressed RGBA texture into a temporary buffer, and then read from that buffer while creating the final compressed texture in the requested format. The code reading from the temporary buffer assumes the buffer is formatted as an array of bytes in RGBA order. However, the buffer is filled using a _mesa_texstore call with MESA_FORMAT_R8G8B8A8_UNORM format -- this is defined as an array of *integers* holding the RGBA values in packed format (least-significant to most-significant). This means incorrect bytes are accessed on big-endian systems. This patch fixes this by using the MESA_FORMAT_A8B8G8R8_UNORM format instead on big-endian systems when filling the buffer. This fixes about 100 piglit test case failures on s390x for me.

* mesa: return initial value for VALIDATE_STATUS if pipe not boundTapani Pälli2015-09-171-1/+2
| | | | | | | | | | | | | | | | | | From OpenGL 4.5 Core spec (7.13): "If pipeline is a name that has been generated (without subsequent deletion) by GenProgramPipelines, but refers to a program pipeline object that has not been previously bound, the GL first creates a new state vector in the same manner as when BindProgramPipeline creates a new program pipeline object." I interpret this as "If GetProgramPipelineiv gets called without a bound (but valid) pipeline object, the state should reflect initial state of a new pipeline object." This is also expected behaviour by ES31-CTS.sepshaderobjs.PipelineApi conformance test. Signed-off-by: Tapani Pälli <[email protected]> Reviewed-by: Marta Lofstedt <[email protected]>

Some properties further require a successful call to either of these commands before taking effect. GetProgramiv returns the properties currently in effect for program, which may differ from the properties set within program since the most recent call to LinkProgram or ProgramBinary, which have not yet taken effect.

| | | | | | | | | | | | 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]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Previously the result of the complicated clamp() expression just dropped on the floor: clamp does not modify any of its parameters. Looking at the surrounding code, I believe this is supposed to modify the value of tex_coord. This change (along with a change to avoid the use of brw_blorp_framebuffer) does not affect any existing piglit tests. I'm not sure what this clamp is trying to accomplish, so I'm not sure how to write a test to exercise this path. I also noticed another bug in this code. There is no way the array texture case could possibly work. This will generate code for the TEXEL_FETCH macro like: #define TEXEL_FETCH(coord) texelFetch(texSampler, ivec3(coord), sample_map[int(2 * fract(coord.x))]); Since the coord parameter of this macro is a vec2 at all invocations, no expansion of this macro will even compile.
