If-statements are not affected because removing flow control can cause the i965 instrution scheduler to create some very long live ranges resulting in unncessary spilling. This causes some shaders to fall of a performance cliff. Since many small if-statements are already flattened to bcsel, this optimization covers more than 68% of the possible cases (2417 shaders helped for instructions on Skylake vs. 3554). v2: Reorder and add whitespace to make the relationship between the patterns more obvious.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most integer operations are omitted because dealing with integer overflow is hard. There are a few things that could be smarter if there was a small amount more tracking of ranges of integer types (i.e., operands are Boolean, operand values fit in 16 bits, etc.). The changes to nir_search_helpers.h are included in this patch to simplify reordering the changes to nir_opt_algebraic.py. v2: Memoize range analysis results. Without this, some shaders appear to get stuck in infinite loops. v3: Rebase on many months of Mesa changes, including 1-bit Boolean changes. v4: Rebase on "nir: Drop imov/fmov in favor of one mov instruction". v5: Use nir_alu_srcs_equal for detecting (a*a). Previously just the SSA value was compared, and this incorrectly matched (a.x*a.y). v6: Many code improvements including (but not limited to) better names, more comments, and better use of helper functions. All suggested by Caio. Rework the handling of several opcodes to use a table for mapping source ranges to a result range. This change fixed a bug that caused fmax(gt_zero, ge_zero) to be incorrectly recognized as ge_zero. Slightly tighten the range of fmul by recognizing that x*x is gt_zero if x is gt_zero. Add similar handling for -x*x. v7: Use _______ in the tables as an alias for unknown. Suggested by Caio. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>

* iris: Fix bad external BO hash table and zombie list interactionsKenneth Graunke2019-08-051-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A while ago, we started deferring GEM object closure and VMA release until buffers were idle. This had some unforeseen interactions with external buffers. We keep imported buffers in hash tables, so if we have repeated imports of the same GEM object, we map those to the same iris_bo structure. This is critical for several reasons. Unfortunately, we broke this assumption. When freeing a non-idle external buffer, we would drop it from the hash tables, then move it to the zombie list. If someone reimported the same GEM object, we would not find it in the hash tables, and go ahead and make a second iris_bo for that GEM object. But the old iris_bo would still be in the zombie list, and so we would eventually call GEM_CLOSE on it - closing a BO that should have still been live. To work around this, we defer removing a BO from the hash tables until it's actually fully closed. This has the strange effect that an external BO may be on the zombie list, and yet be resurrected before it can be properly cleaned up. In this case, we remove it from the list so it won't be freed. Fixes severe instability in Weston, which was hitting EINVALs and ENOENTs from execbuf2, due to batches referring to a GEM object that had been closed, or at least had its VMA torched. Fixes: 457a55716ea ("iris: Defer closing and freeing VMA until buffers are idle.")

| | | | | | | | | | | | | | | | | | | The load uniform/temporary operations output only to a pipeline register, which must be consumed by another op in the same instruction later. The current implementation delays the decision of who will consume this result to until the scheduling step. If the consumer node is not able to use the pipeline register, a mov node may have to be created, during the scheduler step. As part of the ppir scheduler simplification, and now that the ppir scheduler supports pipeline register dependencies, this can be simplified by always creating a single mov node outputting to a normal register that can be used directly by all consumers.

The current implementation creates a mov node to be the predecessor of select, and then relies on an exception during scheduling to ensure that both ops are inserted in the same instruction. Now that the ppir scheduler supports pipeline register dependencies, this can be simplified by making the mov explicitly output to the fmul pipeline register, and the scheduler can place it without an exception. Since the select condition can only be placed in the scalar mult slot, differently than a regular mov, define a separate op for it.

* lima/ppir: support pipeline registers in schedulerErico Nunes2019-08-042-46/+65
| | | | | | | | | | | | | | | | | | | | | | | | | The ppir scheduler grew to be rather complicated and containing many exceptions as it also has to take care of inserting additional nodes when it is mandatory for nodes to be in the same instruction. As such, the lima lowering and scheduling process can be difficult to understand and maintain. The ppir lowering step created nodes hoping that the scheduler would notice the exception and do the right thing. This proposal adds a simple refactor to the scheduler so that it places nodes with pipeline registers in the same instruction. With the scheduler handling this in a general way, it is possible to create same-instruction dependencies by using pipeline registers during the lowering stage. This is simpler to maintain because now we can make these dependencies explicit in a single place (lowering), and we can drop exceptions from scheduling. Reducing the complexity of the scheduler is also useful as preparatory work to support control flow in ppir.

Next commit will remove the ones that were only added for that reason.

It turns out for some shaders, it's actually better to cap at 8 work registers and extra >8 uniform reigsters and tolerate the spilling, since the extra resulting threads make up for the spillage. So incidentally, the shader that spills here is in -bterrain, which jumps from 19fps to 21fps as a result of this change. total instructions in shared programs: 3513 -> 3448 (-1.85%) instructions in affected programs: 776 -> 711 (-8.38%) helped: 20 HURT: 0 helped stats (abs) min: 1 max: 8 x̄: 3.25 x̃: 2 helped stats (rel) min: 3.57% max: 16.00% x̄: 8.37% x̃: 7.19% 95% mean confidence interval for instructions value: -4.28 -2.22 95% mean confidence interval for instructions %-change: -10.02% -6.73% Instructions are helped. total bundles in shared programs: 2067 -> 2024 (-2.08%) bundles in affected programs: 515 -> 472 (-8.35%) helped: 19 HURT: 1 helped stats (abs) min: 1 max: 6 x̄: 2.37 x̃: 2 helped stats (rel) min: 2.13% max: 17.86% x̄: 10.19% x̃: 11.11% HURT stats (abs) min: 2 max: 2 x̄: 2.00 x̃: 2 HURT stats (rel) min: 3.23% max: 3.23% x̄: 3.23% x̃: 3.23% 95% mean confidence interval for bundles value: -3.01 -1.29 95% mean confidence interval for bundles %-change: -12.13% -6.91% Bundles are helped. total quadwords in shared programs: 3468 -> 3426 (-1.21%) quadwords in affected programs: 764 -> 722 (-5.50%) helped: 19 HURT: 1 helped stats (abs) min: 1 max: 5 x̄: 2.26 x̃: 2 helped stats (rel) min: 1.41% max: 12.50% x̄: 6.76% x̃: 7.14% HURT stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 HURT stats (rel) min: 1.08% max: 1.08% x̄: 1.08% x̃: 1.08% 95% mean confidence interval for quadwords value: -2.83 -1.37 95% mean confidence interval for quadwords %-change: -8.08% -4.65% Quadwords are helped. total registers in shared programs: 383 -> 360 (-6.01%) registers in affected programs: 112 -> 89 (-20.54%) helped: 19 HURT: 0 helped stats (abs) min: 1 max: 3 x̄: 1.21 x̃: 1 helped stats (rel) min: 12.50% max: 27.27% x̄: 20.63% x̃: 20.00% 95% mean confidence interval for registers value: -1.47 -0.95 95% mean confidence interval for registers %-change: -22.39% -18.87% Registers are helped. total threads in shared programs: 432 -> 451 (4.40%) threads in affected programs: 19 -> 38 (100.00%) helped: 11 HURT: 0 helped stats (abs) min: 1 max: 2 x̄: 1.73 x̃: 2 helped stats (rel) min: 100.00% max: 100.00% x̄: 100.00% x̃: 100.00% 95% mean confidence interval for threads value: 1.41 2.04 95% mean confidence interval for threads %-change: 100.00% 100.00% Threads are [helped]. total loops in shared programs: 4 -> 4 (0.00%) loops in affected programs: 0 -> 0 helped: 0 HURT: 0 total spills in shared programs: 0 -> 4 spills in affected programs: 0 -> 4 helped: 0 HURT: 2 total fills in shared programs: 0 -> 7 fills in affected programs: 0 -> 7 helped: 0 HURT: 2 Signed-off-by: Alyssa Rosenzweig <[email protected]>

* pan/midgard: Switch sources to an array for trinary sourcesAlyssa Rosenzweig2019-08-0212-145/+133
| | | | | | | | | We need three independent sources to support indirect SSBO writes (as well as textures with both LOD/bias and offsets). Now is a good time to make sources just an array so we don't have to rewrite a ton of code if we ever needed a fourth source for some reason. Signed-off-by: Alyssa Rosenzweig <[email protected]>
* pan/midgard: Remove "r27-only" register classAlyssa Rosenzweig2019-08-025-97/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As far as I know, there's no such thing as a load/store op that only takes its argument in r27. We just need to set the appropriate arg_1 field in the RA to specify other registers if we want them. To facilitate this, various RA-related changes are needed across the compiler ; this should also fix indirect offsets which were implicitly interpreted as "r27-only" despite not even passing through RA yet. One ripple effect change is switching the move insertion point and adjusting the liveness analysis accordingly, so while this was intended as a purely functional change, there are some shader-db changes: total instructions in shared programs: 3511 -> 3498 (-0.37%) instructions in affected programs: 563 -> 550 (-2.31%) helped: 12 HURT: 0 helped stats (abs) min: 1 max: 2 x̄: 1.08 x̃: 1 helped stats (rel) min: 0.93% max: 5.00% x̄: 2.58% x̃: 2.33% 95% mean confidence interval for instructions value: -1.27 -0.90 95% mean confidence interval for instructions %-change: -3.23% -1.93% Instructions are helped. total bundles in shared programs: 2067 -> 2067 (0.00%) bundles in affected programs: 398 -> 398 (0.00%) helped: 7 HURT: 4 helped stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 helped stats (rel) min: 1.54% max: 10.00% x̄: 5.04% x̃: 5.56% HURT stats (abs) min: 1 max: 2 x̄: 1.75 x̃: 2 HURT stats (rel) min: 2.13% max: 4.26% x̄: 3.72% x̃: 4.26% 95% mean confidence interval for bundles value: -0.95 0.95 95% mean confidence interval for bundles %-change: -5.21% 1.50% Inconclusive result (value mean confidence interval includes 0). total quadwords in shared programs: 3464 -> 3454 (-0.29%) quadwords in affected programs: 1199 -> 1189 (-0.83%) helped: 18 HURT: 4 helped stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 helped stats (rel) min: 1.03% max: 5.26% x̄: 2.44% x̃: 1.79% HURT stats (abs) min: 2 max: 2 x̄: 2.00 x̃: 2 HURT stats (rel) min: 2.56% max: 2.82% x̄: 2.63% x̃: 2.56% 95% mean confidence interval for quadwords value: -0.98 0.07 Inconclusive result (value mean confidence interval includes 0). total registers in shared programs: 383 -> 373 (-2.61%) registers in affected programs: 56 -> 46 (-17.86%) helped: 12 HURT: 2 helped stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 helped stats (rel) min: 9.09% max: 33.33% x̄: 29.58% x̃: 33.33% HURT stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 HURT stats (rel) min: 20.00% max: 50.00% x̄: 35.00% x̃: 35.00% 95% mean confidence interval for registers value: -1.13 -0.29 95% mean confidence interval for registers %-change: -35.07% -5.63% Registers are helped.
