* r600/sb: use different stacks for tracking lds and queue usage.Dave Airlie2018-01-182-3/+24
| | | | | | | | | | | | | | The normal ssa renumbering isn't sufficient for LDS queue access, this uses two stacks, one for the lds queue, and one for the lds r/w ordering. The LDS oq values are incremented in their use in a linear fashion. The LDS rw values are incremented in their definitions and used in the next lds operation to ensure reordering doesn't occur.

* r600/sb: schedule LDS ops in appropriate places.Dave Airlie2018-01-182-0/+7
| | | | | | | | | | So LDS ops have to be SLOT_X, and LDS OQ reads have read port restrictions so we try and force those into only having one per slot and avoiding bank swizzles. Acked-By: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* r600/sb: hit the scheduler with a big hammer to avoid lds splits.Dave Airlie2018-01-181-0/+3
| | | | | | | | | | | | | This tries to avoid an lds queue read getting scheduled separately from an lds ret read, the non-sb code uses the same style of hammer, this isn't foolproof. We can do better, but it's a bit tricky, as you have to scan ahead and either schedule more lds oq moves and more lds reads and that could lead to you running out of space anyways.

* r600/sb: adding lds oq tracking to the schedulerDave Airlie2018-01-182-3/+15
| | | | | | | | | | | This adds support for tracking the lds oq read/writes so can avoid scheduling other things in between. This patch just adds the tracking and assert to show problems. Acked-By: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* r600/sb: add gcm support to avoid clause between lds read/queue readDave Airlie2018-01-182-2/+17
| | | | | | | | | | You have to schedule LDS_READ_RET _, x and MOV reg, LDS_OQ_A_POP in the same basic block/clause. This makes sure once we've issues and MOV we don't add another block until we balance it with an LDS read.

* r600/sb: introduce special register values for lds support.Dave Airlie2018-01-183-1/+33
| | | | | | | | | | | | | For LDS read/write ordering we use the LDS_RW value, reads will wait on previous writes. For LDS read/read from LDS queue ordering we use the LDS_OQ values, we define two for now, though initially we'll just support OQA.

* r600/sb: update last_cf if alu is the last clauseDave Airlie2018-01-181-0/+1
| | | | | | | | | | | It's rare to have a final alu clause on normal shaders (exports) but tess shaders write to LDS as their output, so we see some alu clauses, and the CF_END get put in the wrong place.

| | | | | | | | | | | | Some tess shaders were doing MOVA_INT _, c0.x on cayman, and then hitting an assert in sb_bc_finalize.cpp:translate_kcache.

| | | | | | | | | | | Now that we have two of these, we're duplicating a bunch of this logic. The next commit will add more logic, which would make the duplication seem worse.

* intel/fs: Optimize and simplify the copy propagation dataflow logic.Francisco Jerez2018-01-171-24/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the dataflow propagation algorithm would calculate the ACP live-in and -out sets in a two-pass fixed-point algorithm. The first pass would update the live-out sets of all basic blocks of the program based on their live-in sets, while the second pass would update the live-in sets based on the live-out sets. This is incredibly inefficient in the typical case where the CFG of the program is approximately acyclic, because it can take up to 2*n passes for an ACP entry introduced at the top of the program to reach the bottom (where n is the number of basic blocks in the program), until which point the algorithm won't be able to reach a fixed point. The same effect can be achieved in a single pass by computing the live-in and -out sets in lock-step, because that makes sure that processing of any basic block will pick up the updated live-out sets of the lexically preceding blocks. This gives the dataflow propagation algorithm effectively O(n) run-time instead of O(n^2) in the acyclic case. The time spent in dataflow propagation is reduced by 30x in the GLES31.functional.ssbo.layout.random.all_shared_buffer.5 dEQP test-case on my CHV system (the improvement is likely to be of the same order of magnitude on other platforms). This more than reverses an apparent run-time regression in this test-case from my previous copy-propagation undefined-value handling patch, which was ultimately caused by the additional work introduced in that commit to account for undefined values being multiplied by a huge quadratic factor. According to Chad this test was failing on CHV due to a 30s time-out imposed by the Android CTS (this was the case regardless of my undefined-value handling patch, even though my patch substantially exacerbated the issue). On my CHV system this patch reduces the overall run-time of the test by approximately 12x, getting us to around 13s, well below the time-out. v2: Initialize live-out set to the universal set to avoid rather pessimistic dataflow estimation in shaders with cycles (Addresses performance regression reported by Eero in GpuTest Piano). Performance numbers given above still apply. No shader-db changes with respect to master.
