| | | | | | | | | | | | | | | | | | | | | | | | | | | Packet 3DSTATE_CONSTANT_PS is still emitted explicitly as ps stage itself is enabled and hardware may try to prefetch constants from the buffer. From the BSpec: 3D Pipeline - Windower - 3DSTATE_PUSH_CONSTANT_ALLOC_PS "Specifies the size of the PS constant buffer. This value will determine the amount of data the command stream can pre-fetch before the buffer is full." This is not possible on gen6. From the BSpec about 3DSTATE_CONSTANT_PS: "This packet must be followed by WM_STATE." Binding table emissions for stages other than PS can be now dropped, they were only needed for the 3DSTATE_CONSTANT_XS to be effective: From the BSpec: "The 3DSTATE_CONSTANT_* command is not committed to the shader unit until the corresponding (same shader) 3DSTATE_BINDING_TABLE_POINTER_* command is parsed."

On gen6 this test was already working without this change. It keeps working after it. This commit replaces the call to brw_emit_mi_flush for gen6+ with two calls to brw_emit_pipe_control_flush: * The first one with RENDER_TARGET_FLUSH and CS_STALL set to initiate a render cache flush after any concurrent rendering completes and cause the CS to stop parsing commands until the render cache becomes coherent with memory. * The second one have TEXTURE_CACHE_INVALIDATE set (and no CS stall) to clean up any stale data from the sampler caches before rendering continues. Didn't touch gen4-5, basically because I don't have a way to test them.

| | | | | | | | | | | | | | | | | There are two distinctly different uses of this struct. The first is to store GL shader objects. The second is to store information about a shader stage thats been linked. The two uses actually share few fields and there is clearly confusion about their use. For example the linked shaders map one to one with a program so can simply be destroyed along with the program. However previously we were calling reference counting on the linked shaders. We were also creating linked shaders with a name even though it is always 0 and called the driver version of the _mesa_new_shader() function unnecessarily for GL shader objects.

* i965: Make emit_urb_writes() not produce an EOT message for GS.Kenneth Graunke2016-06-271-0/+7
| | | | | | | | | | | | | | | | | | | | | | | emit_urb_writes() contains code to emit an EOT write with no actual data when there are no output varyings. This makes sense for the VS and TES stages, where it's called once at the end of the program. However, in the geometry shader stage, emit_urb_writes() is called once for every EmitVertex(). We explicitly emit a URB write with EOT set at the end of the shader, separately from this path. So we'd better not terminate the thread. This could get us into trouble for shaders which do EmitVertex() with no varyings followed by SSBO/image/atomic writes. It also caused us to emit multiple sends with EOT set, which apparently confuses the register allocator into not using g112-g127 for all but the first one. This caused EU validation failures in OglGSCloth shaders in shader-db. (The actual application was fine, but shader-db thinks there are no outputs because it doesn't understand transform feedback.)

| | | | | | | | | | | | | | | | | | | | | | | | | On MRF platforms, we need to set base_mrf to the first MRF value we'd like to use for the message. On send-from-GRF platforms, we set it to -1 to indicate that the operation doesn't use MRFs. As MRF platforms are becoming increasingly a thing of the past, we've forgotten to bother with this. It makes more sense to set it to -1 by default, so we don't have to think about it for new code. I searched the code for every instance of 'mlen =' in brw_fs*cpp, and it appears that all MRF-based messages correctly program a base_mrf. Forgetting to set base_mrf = -1 can confuse the register allocator, causing it to think we have a large fake-MRF region. This ends up moving the send-with-EOT registers earlier, sometimes even out of the g112-g127 range, which is illegal. For example, this fixes illegal sends in Piglit's arb_gpu_shader_fp64-layout-std430-fp64-shader, which had SSBO messages with mlen > 0 but base_mrf == 0.

* i965: Implement rasterizer discard via SOL unless required for queries.Kenneth Graunke2016-06-232-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use CL_INVOCATION_COUNT for the GL_PRIMITIVES_GENERATED query, which involves passing all primitives to the clipper. When rasterizer discard is enabled, we program the clipper in REJECT_ALL mode, rather than using the SOL stage's "Rendering Disable" feature. See commit f09b91f78247409f54c975f56cb10d5f350fe64e for an explanation of why we implement GL_PRIMITIVES_GENERATED this way. Apparently the SOL stage's "Rendering Disable" feature is a lot faster than having the clipper reject all primitives. It's safe to use when no GL_PRIMITIVES_GENERATED query is active, as we don't care about CL_INVOCATION_COUNT incrementing. This patch makes us use SO_RENDERING_DISABLE when no query is active, but continues falling back to the clipper in REJECT_ALL mode when the queries are enabled. It brings back the perf_debug for the clipper case (which I removed in commit 1f9445ff57b, thinking it wasn't useful).
