* glsl: relax input->output validation for SSO programsTapani Pälli2015-04-071-1/+1
| | | | | | | | | | | | | | Commit 18004c3 introduced more restrictive validation to linker between inputs and outputs. This patch skips the additional check for programs that utilize GL_ARB_separate_shader_objects, there inputs and outputs might not make exact match during linking but only when constructing the final pipeline. This made some of the GL_ARB_program_interface_query tests shaders fail to link, these tests can be used to verify the change.

* nv50,nvc0: limit the y-tiling of 3d textures to the first level's tilingIlia Mirkin2015-04-063-10/+13
| | | | | | | | | | | | | | We limit y-tiling to 0x20 when depth is involved. However the function is run for each miplevel, and the hardware expects miplevel 0 to have the highest tiling settings. Perform the y-tiling limit on all levels of a 3d texture, not just the ones that have depth.

* i965: Do not render primitives in non-zero streams then TF is disabledIago Toral Quiroga2015-04-061-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Haswell hardware seems to ignore Render Stream Select bits from 3DSTATE_STREAMOUT packet when the SOL stage is disabled even if the PRM says otherwise. Because of this, all primitives are sent down the pipeline for rasterization, which is wrong. If SOL is enabled, Render Stream Select is honored and primitives bound to non-zero streams are discarded after stream output. Since the only purpose of primives sent to non-zero streams is to be recorded by transform feedback, we can simply discard all geometry bound to non-zero streams then transform feedback is disabled to prevent it from ever reaching the rasterization stage. Notice that this patch introduces a small change in the behavior we get when a geometry shader emits more vertices than the maximum declared: before, a vertex that was emitted to a non-zero stream when TF was disabled would still count for the purposes of checking that we don't exceed the maximum number of output vertices declared by the shader. With this change, these vertices are completely ignored and won't increase the output vertex count, making more room for other (hopefully more useful) vertices. Fixes piglit test arb_gpu_shader5-emitstreamvertex_nodraw on Haswell and Broadwell. v2 (Ken): Drop is_haswell check in favor of doing this unconditionally. Broadwell needs the workaround as well, and it doesn't hurt to do it in general. Also tweak comments - the Haswell PRM does actually mention this ("Command Reference: Instructions" page 797).

* i965: Free dead GLSL IR one last time.Kenneth Graunke2015-04-061-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | While working on NIR's memory allocation model, I realized the GLSL IR memory model was broken. During glCompileShader, we allocate everything out of the _mesa_glsl_parse_state context, and reparent it to gl_shader at the end. During glLinkProgram, we allocate everything out of a temporary context, then reparent it to the exec_list containing the linked IR. But during brw_link_shader - the driver's final opportunity to do lowering and optimization - we just allocated everything out of the permanent context given to us by the linker. That memory stayed forever. Notably, passes like brw_fs_channel_expressions cause us to churn the majority of the code, so we really want to free dead IR here. Saves 125MB of memory when replaying a Dota 2 trace on Broadwell. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
* i965: Implement SIMD16 texturing on Gen4.Kenneth Graunke2015-04-063-10/+90
| | | | | | | | | | | | | | | | | | | | | | | | | This allows SIMD16 mode to work for a lot more programs. Texturing is also more efficient in SIMD16 mode than SIMD8. Several messages don't actually exist in SIMD8 mode, so we did SIMD16 messages and threw away half of the data. Now we compute real data in both halves. Also, the SIMD16 "sample" message doesn't require all three coordinate components to exist (like the SIMD8 one), so we can shorten the message lengths, cutting register usage a bit. I chose to implement the visitor functionality in a separate function, since mixing true SIMD16 with SIMD8 code that uses SIMD16 fallbacks seemed like a mess. The new code bails on a few cases where we'd have to do two SIMD8 messages - we just fall back to SIMD8 for now. Improves performance in "Shadowrun: Dragonfall - Director's Cut" by about 20% on GM45 (measured with LIBGL_SHOW_FPS=1 while standing around in the first mission). v2: Add ir_txf to the has_lod case (caught by Jordan Justen).

* i965: Use SIMD16 instead of SIMD8 on Gen4 when possible.Kenneth Graunke2015-04-062-3/+4
| | | | | | | | | | | | | | | | | | | | | | | Gen5+ systems allow you to specify multiple shader programs - both SIMD8 and SIMD16 - and the hardware will automatically dispatch to the most appropriate one, given the number of subspans to be processed. However, that is not the case on Gen4. Instead, you program a single shader. If you enable multiple dispatch modes (SIMD8 and SIMD16), the shader is supposed to contain a series of jump instructions at the beginning. The hardware will launch the shader at a small offset, hitting one of the jumps. We've always thought that sounds like a pain, and weren't clear how it affected performance - is it worth having multiple shader types? So, we never bothered with SIMD16 until now. This patch takes a simpler approach: try and compile a SIMD16 shader. If possible, set the no_8 flag, telling the hardware to just use the SIMD16 variant all the time.

* freedreno/ir3: add NIR compilerRob Clark2015-04-057-5/+1762
| | | | | | | | | | | | | | | | The NIR compiler frontend is an alternative to the TGSI f/e, producing the same ir3 IR and using the same backend passes for scheduling, etc. It is not enabled by default yet, as there are still some regressions. To enable, use 'FD_MESA_DEBUG=nir'. It is enough to use with, for example, xonotic or supertuxkart. With the NIR f/e, scalarizing and a number of other lowering steps happen in NIR, so we don't have to do them in ir3.
