* i965/query: Cache whether the batch references the query BO.Kenneth Graunke2014-12-162-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chris Wilson noted that repeated calls to CheckQuery() would call drm_intel_bo_references(brw->batch.bo, query->bo) on each invocation, which is expensive. Once we've flushed, we know that future batches won't reference query->bo, so there's no point in asking more than once. This patch adds a brw_query_object::flushed flag, which is a conservative estimate of whether the batch has been flushed. On the first call to CheckQuery() or WaitQuery(), we check if the batch references query->bo. If not, it must have been flushed for some reason (such as being full). We record that it was flushed. If it does reference query->bo, we explicitly flush, and record that we did so. Any subsequent checks will simply see that query->flushed is set, and skip the drm_intel_bo_references() call. Inspired by a patch from Chris Wilson. According to Eero, this does not affect the performance of Witcher 2 on Haswell, but approximately halves the userspace CPU usage.

* i965/query: Use brw_bo_map to handle stall warnings.Kenneth Graunke2014-12-161-7/+1
| | | | | | | | | | This is less code and also measures the duration of the stall for us. Our old code predates the existance of brw_bo_map(). Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ben Widawsky <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* i965/query: Remove redundant drm_intel_bo_references call in CheckQuery.Kenneth Graunke2014-12-161-7/+8
| | | | | | | | | | | | | | | | | | | | | | CheckQuery calls drm_intel_bo_references to see if the batch references the query BO, and if so, flushes. It then checks if the query BO is busy, and if not, calls gen6_queryobj_get_results(). Stupidly, gen6_queryobj_get_results() immediately did a second redundant drm_intel_bo_references check, even though we know the buffer is not referenced and in fact idle. This patch moves the batch-flush check out of gen6_queryobj_get_results and into WaitQuery() (the other caller). That way, both callers do a single batch-flush check. This should only be a minor improvement, since it would only affect the first CheckQuery call where the result is actually available.

* i965/query: Add query->bo == NULL early return in CheckQuery hook.Kenneth Graunke2014-12-161-2/+8
| | | | | | | | | | | If query->bo == NULL, this is a redundant CheckQuery call, and we should simply return. We didn't do anything anyway - we skipped the batch flushing block, and although we called get_results(), it has an early return and does nothing. Why bother?

* i965/query: Set Ready flag in gen6_queryobj_get_results().Kenneth Graunke2014-12-161-2/+2
| | | | | | | | | | | | | | | q->Ready means that the results are in, and core Mesa is free to return them to the application. gen6_queryobj_get_results() is a natural place to set that flag; doing so means callers don't have to. The older non-hardware-context aware code couldn't do this, because we had to call brw_queryobj_get_results() to gather intermediate results when we ran out of space for snapshots in the query buffer. We only gather complete results in the Gen6+ code, however.

* gallium: add TGSI_SEMANTIC_VERTEXID_NOBASE and TGSI_SEMANTIC_BASEVERTEXRoland Scheidegger2014-12-1619-6/+84
| | | | | | | | | | | | | | | | | | | Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not supporting vertex ids with base vertex offset applied (so, only support d3d10-style vertex ids) will get such a d3d10-style vertex id instead - with the caveat they'll also need to handle the basevertex system value too (this follows what core mesa already does). Additionally, this is also useful for other state trackers (for instance llvmpipe / draw right now implement the d3d10 behavior on purpose, but with different semantics it can just do both). Doesn't do anything yet. And fix up the docs wrt similar values. v2: incorporate feedback from Brian and others, better names, better docs.

* r600g/sb: implement r600 gpr index workaround. (v3.1)Dave Airlie2014-12-164-9/+57
| | | | | | | | | | | | | | | | | | | | | | | r600, rv610 and rv630 all have a bug in their GPR indexing and how the hw inserts access to PV. If the base index for the src is the same as the dst gpr in a previous group, then it will use PV instead of using the indexed gpr correctly. The workaround is to insert a NOP when you detect this. v2: add second part of fix detecting DST rel writes followed by same src base index reads. v3: forget adding stuff to structs, just iterate over the previous node group again, makes it more obvious. v3.1: drop local_nop.
