* ra: Add a callback for selecting a register from what's available.Eric Anholt2017-07-251-14/+76
| | | | | | | | | | | | | | | | VC4 has had a tension, similar to pre-Sandybridge Intel, where we want to use low-numbered registers (more parallelism on Intel, fewer delay slots on vc4), but in order to give instruction scheduling the most freedom to avoid delays we want to round-robin between registers of the same cost. Our two heuristics so far have chosen one end or the other of that tradeoff. The callback, instead, hands the driver the set of registers that are available, and the driver gets to make its own choice. This will be used in vc4 to round-robin between registers of the same cost, and might be used in the future for improving bank selection. Reviewed-by: Nicolai Hähnle <[email protected]>
* ra: Don't put a node in its own adjacency set.Eric Anholt2017-07-251-13/+10
| | | | | | | | All the paths looping over adjacency had guards against considering themselves (the non-obvious one was ra_any_neighbors_conflict(), which has in_stack set). Reviewed-by: Nicolai Hähnle <[email protected]>

* util/ra: Make allocating conflict lists optionalJason Ekstrand2015-08-181-9/+17
| | | | | | | | | Since i965 is now using make_reg_conflicts_transitive and doesn't need q-value computations, they are disabled on i965. They are enabled everywhere else so that they get the old behavior. This reduces the time spent in eglInitialize() on BDW by around 10-15%. Reviewed-by: Eric Anholt <[email protected]>

* ra: Disable round-robin strategy for optimistically colorable nodes.Francisco Jerez2015-02-231-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The round-robin allocation strategy is expected to decrease the amount of false dependencies created by the register allocator and give the post-RA scheduling pass more freedom to move instructions around. On the other hand it has the disadvantage of increasing fragmentation and decreasing the number of equally-colored nearby nodes, what increases the likelihood of failure in presence of optimistically colorable nodes. This patch disables the round-robin strategy for optimistically colorable nodes. These typically arise in situations of high register pressure or for registers with large live intervals, in both cases the task of the instruction scheduler shouldn't be constrained excessively by the dense packing of those nodes, and a spill (or on Intel hardware a fall-back to SIMD8 mode) is invariably worse than a slightly less optimal scheduling. Shader-db results on the i965 driver: total instructions in shared programs: 5488539 -> 5488489 (-0.00%) instructions in affected programs: 1121 -> 1071 (-4.46%) helped: 1 HURT: 0 GAINED: 49 LOST: 5 v2: Re-enable round-robin already for the lowest one of the nodes pushed optimistically onto the sack (Connor). v3: Use UINT_MAX instead of ~0, open-code MIN2 (Jason, Connor).

* ra: Don't use regs as the ralloc context.Matt Turner2014-12-011-1/+1
| | | | | | | | | | The i965 backends pass something out of 'screen', which is allocated per-process, making using this as a ralloc context not thread-safe. All callers ra_alloc_interference_graph() already ralloc_free() its return value. Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | This shouldn't be a functional change since reg_belongs_to_class is just a wrapper around BITSET_TEST. It just makes the code a little easier to read. Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>

The r300 gallium driver is using it outside of the Mesa tree, and I wanted to do so for vc4 as well. Rather than make the multiple-definitions problem even more complicated, just move it to more-shared code. v2: Don't forget to delete the symlink in r300 (review by Matt).
