* radeonsi: use a single descriptor for the GSVS ringNicolai Hähnle2016-12-124-50/+67
| | | | | | | | | We can hardcode all of the fields for swizzling in the geometry shader. The advantage is that we use fewer descriptor slots and we no longer have to update any of the (ring) descriptors when the geometry shader changes. Reviewed-by: Marek Olšák <[email protected]>
* radeonsi: pack GS output components for each vertex stream contiguouslyNicolai Hähnle2016-12-121-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note that the memory layout of one vertex stream inside one "item" (= memory written by one GS wave) on the GSVS ring is: t0v0c0 ... t15v0c0 t0v1c0 ... t15v1c0 ... t0vLc0 ... t15vLc0 t0v0c1 ... t15v0c1 t0v1c1 ... t15v1c1 ... t0vLc1 ... t15vLc1 ... t0v0cL ... t15v0cL t0v1cL ... t15v1cL ... t0vLcL ... t15vLcL t16v0c0 ... t31v0c0 t16v1c0 ... t31v1c0 ... t16vLc0 ... t31vLc0 t16v0c1 ... t31v0c1 t16v1c1 ... t31v1c1 ... t16vLc1 ... t31vLc1 ... t16v0cL ... t31v0cL t16v1cL ... t31v1cL ... t16vLcL ... t31vLcL ... t48v0c0 ... t63v0c0 t48v1c0 ... t63v1c0 ... t48vLc0 ... t63vLc0 t48v0c1 ... t63v0c1 t48v1c1 ... t63v1c1 ... t48vLc1 ... t63vLc1 ... t48v0cL ... t63v0cL t48v1cL ... t63v1cL ... t48vLcL ... t63vLcL where tNN indicates the thread number, vNN the vertex number (in the order of EMIT_VERTEX), and cNN the output component (vL and cL are the last vertex and component, respectively). The vertex streams are laid out sequentially. The swizzling by 16 threads is hard-coded in the way the VGT generates the offset passed into the GS copy shader, and the jump every 16 threads is calculated from VGT_GSVS_RING_OFFSET_n and VGT_GSVS_RING_ITEMSIZE in a way that makes it difficult to deviate from this layout (at least that's what I've experimentally confirmed on VI after first trying to go the simpler route of just interleaving the vertex streams).

| | | | | | | | | | | | SimplifyCFG generates a switch instruction anyway when all four streams are present, but is simultaneously not smart enough to eliminate some redundant jumps that it generates. The generated assembly is still a bit silly, probably because the control flow annotation doesn't know how to handle a switch with uniform condition. Reviewed-by: Marek Olšák <[email protected]>

| | | | | | | | When running the copy shader for vertex streams != 0, the SX does not need any data from us (there is no rasterization for the higher vertex streams, only streamout). Reviewed-by: Marek Olšák <[email protected]>
* radeonsi: do not export VS outputs from vertex streams != 0Nicolai Hähnle2016-12-121-0/+6
| | | | | | | | | | | | This affects for GS copy shaders. When an output is meant for vertex stream != 0, then we don't have to make it available to the pixel shader. There is a minor inefficiency here because the GLSL varying packing pass does not group varyings of the same vertex stream together, but it shouldn't be important in practice.

* radeonsi: do not kill GS with memory writesNicolai Hähnle2016-12-121-8/+22
| | | | | | | | | | | Vertex emits beyond the specified maximum number of vertices are supposed to have no effect, which is why we used to always kill GS that reached the limit. However, if the GS also writes to memory (SSBO, atomics, shader images), then we must keep going and only skip the vertex emit itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | GetFramebufferAttachmentParameteriv should return GL_LINEAR for the window system default framebuffer's GL_DEPTH or GL_STENCIL attachments when there are zero depth or stencil bits. The GL 4.5 spec's GetFramebufferAttachmentParameteriv section says: "If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is not NONE, these queries apply to all other framebuffer types: [...] If attachment is not a color attachment, or no data storage or texture image has been specified for the attachment, then params will contain the value LINEAR." Note that we already return LINEAR for the case where there is an actual depth or stencil renderbuffer attached. In the case modified by this patch, FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE returns FRAMEBUFFER_DEFAULT rather than NONE.
