* i965 Gen6+: Invalidate VF address-based cache on flushPaul Berry2011-12-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although there is not much documentation of this fact, there are in fact two separate VF caches: - an "index-based" cache (described in the Sandy Bridge PRM, vol 2 part 1, section 2.1.2 "Vertex Cache"). This cache stores URB handles of vertex shader outputs; its purpose is to avoid redundant invocations of the vertex shader when drawing in random access mode (e.g. glDrawElements()), and the same vertex index is specified multiple times. It is automatically invalidated between 3D_PRIMITIVE commands and between instances within a single 3D_PRIMITIVE command. - an "address-based" cache (mentioned briefly in vol 2 part 1, section 1.7.4 "PIPE_CONTROL Command"). This cache stores the data read from vertex buffers; its purpose is to avoid redundant memory accesses when doing instanced drawing or when multiple 3D_PRIMITIVE commands access the same vertex data. It needs to be manually invalidated whenever new data is written to a buffer that is used for vertex data. Previous to this patch, it was not necessary for Mesa to explicitly invalidate the address-based cache, because there were no reasonable use cases in which the GPU would write to a vertex data buffer during a batch, and inter-batch flushing was taken care of by the kernel. However, with transform feedback, there is now a reasonable use case: vertex data is written to a buffer using transform feedback, and then that data is immediately re-used as vertex input in the next drawing operation. To make this use case work, we need to flush the address-based VF cache between transform feedback and the next draw operation. Since we are already calling intel_batchbuffer_emit_mi_flush() when transform feedback completes, and intel_batchbuffer_emit_mi_flush() is intended to invalidate all caches, it seems reasonable to add VF cache invalidation to this function. As with commit 63cf7fad13fc9cfdd2ae7b031426f79107000300 (i965: Flush pipeline on EndTransformFeedback), this is not an ideal solution. It would be preferable to only invalidate the VF cache if the next draw call was about to consume data generated by a previous draw call in the same batch. However, since we don't have the necessary dependency tracking infrastructure to figure that out right now, we have to overzealously invalidate the cache. Fixes Piglit test "EXT_transform_feedback/immediate-reuse". Reviewed-by: Kenneth Graunke <[email protected]>

* softpipe: try and use back color for a slot if color fails.Dave Airlie2011-12-221-0/+5
| | | | | | | | | | | | | | In the case where a front and back output are specified, the draw code will copy the back output into the front color slot and everything is happy. However if no front is specified then the draw code will do a bad copy (separate patch), but also the frag shader won't pick up the color as there there is no write to COLOR from the vertex shader just BCOLOR. This patch fixes that problem so if it can't find a vertex shader output for the front color slot, it will go and lookup and use one for the back color slot.

| | | | | | | | | | | | | | | | | | | | Previously we were storing the RasterDiscard flag (for GL_RASTERIZER_DISCARD) in gl_context::TransformFeedback. This was confusing, because we use the _NEW_TRANSFORM flag (not _NEW_TRANSFORM_FEEDBACK) to track state updates to it, and because rasterizer discard has effects even when transform feedback is not in use. This patch makes RasterDiscard a toplevel element in gl_context rather than a subfield of gl_context::TransformFeedback. Note: We can't put RasterDiscard inside gl_context::Transform, since all items inside gl_context::Transform need to be pieces of state that are saved and restored using PushAttrib and PopAttrib.

| | | | | | | | | | | | | | | | | | | | This patch adds software-based PRIMITIVES_GENERATED and TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN queries that work by keeping track of the number of primitives that are sent down the pipeline, and adjusting as necessary to account for the way each primitive type is tessellated. In the long run we'll want to replace this with a hardware-based implementation, because the software approach won't work with geometry shaders or primitive restart. However, at the moment, we don't have the necessary kernel support to implement a hardware-based query (we would need the kernel to save GPU registers when context switching, so that drawing performed by another process doesn't get counted).

| | | | | | | | | | | | | | | | We don't currently have kernel support for saving GPU registers on a context switch, so if multiple processes are performing transform feedback at the same time, their SVBI registers will interfere with each other.

| | | | | | | | | | | | | | | | | | | This patch enables rasterizer discard functionality (a part of transform feedback) in Gen6, by generating an alternate GS program when rasterizer discard is active. Instead of forwarding vertices down the pipeline, the alternate GS program uses a URB Write message to deallocate the URB entry that was allocated by FF sync and terminate the thread. Note: parts of the Sandy Bridge PRM seem to imply that we could do this more efficiently, by clearing the GEN6_GS_RENDERING_ENABLE bit, and not allocating a URB entry at all. However, it's not clear how we are supposed to terminate the thread if we do that. Volume 2 part 1, section 4.5.4, says "GS threads must terminate by sending a URB_WRITE message with the EOT and Complete bits set.", and my experiments so far confirm that.
