* nir: Rely on the fact that bcsel takes a well formed boolean.Kenneth Graunke2016-08-191-3/+3
| | | | | | | | | | | | | | | According to Connor, it's safe to assume that the first operand of bcsel, as well as the operand of b2f and b2i, must be well formed booleans. https://lists.freedesktop.org/archives/mesa-dev/2016-August/125658.html With the previous improvements to a@bool handling, this now has no change in shader-db instruction counts on Broadwell.

* i965/sched: Change the scheduling heuristics to favor early program termination.Francisco Jerez2016-08-181-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses the unblocked time of the exit assigned to each available node to attempt to unblock exit nodes as early as possible, potentially reducing the runtime of the shader when an exit branch is taken. There is a natural trade-off between terminating the program as early as possible and reducing the worst-case latency of the program as a whole (since this will typically move exit-unblocking nodes closer to its dependencies potentially causing additional stalls of the execution pipeline), but in practice the bandwidth and ALU cycle savings from terminating the program earlier tend to outweigh the slight increase in worst-case program execution latency, so it makes sense to prefer nodes likely to unblock an earlier exit regardless of the latency benefits of other available nodes. I haven't observed any benchmark regressions from this change after testing on VLV, HSW, BDW, BSW and SKL. The FPS of the GfxBench Manhattan benchmark increases by 10%-20% and the FPS of Unigine Valley improves by roughly 5% depending on the platform and settings. The change to the register pressure-sensitive heuristic is rather conservative and gives precedence to the existing heuristic in order to avoid increasing register pressure and causing spill count and SIMD width regressions in shader-db. It may make sense to revisit this with additional performance data. Reviewed-by: Jason Ekstrand <[email protected]>
* i965/sched: Assign a preferred exit node to each node of the dependency graph.Francisco Jerez2016-08-181-0/+59
| | | | | | | | | | | | | This adds a bit of metadata to schedule_node that will be used to compare available nodes in the scheduling heuristic code based on which of them unblocks the earliest successor exit node. Note that assigning exit nodes wouldn't be necessary in a bottom-up scheduler because we could achieve the same effect by scheduling the exit nodes themselves appropriately. No shader-db changes.

* i965/sched: Calculate the critical path of scheduling nodes non-recursively.Francisco Jerez2016-08-181-13/+12
| | | | | | | | | | | | | | | | | | | The critical path of each node is calculated by induction based on the critical paths of its children, which can be done in a post-order depth-first traversal of the dependency graph. The current code implements graph traversal by iterating over all nodes of the graph and then recursing into its children -- But it turns out that recursion is unnecessary because the lexical order of instructions in the block is already a good enough reverse post-order of the dependency graph (if it weren't a reverse post-order some instruction would have been located before one of its dependencies in the original ordering of the basic block, which is impossible), so we just need to walk the instruction list in reverse to achieve the same result more efficiently. No shader-db changes. Reviewed-by: Jason Ekstrand <[email protected]>
* i965/fs: Switch to per-subspan discard jumps.Francisco Jerez2016-08-181-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ANY4H is more efficient than ANY8H and ANY16H because it makes sure that whenever a whole subspan hits a discard statement it gets disabled by the EU until the end of the program, regardless of whether the discard condition is uniform across all channels of the SIMD8-16 thread. OTOH ANY8H/ANY16H would cause the rest of the program to be executed for *all* channels if only one of the channels hadn't taken the discard branch, potentially increasing the bandwidth and ALU usage of the program unnecessarily. This change increases the FPS by over 3x of a simple micro-benchmark that discards a bunch of fragments and then does a single costly texturing operation. I've just re-verified the FPS change on HSW and SKL, but I expect all platforms from Gen6 up to get a similar benefit. Note that we could potentially be more aggressive and use the NORMAL predicate to discard individual channels, but that would need to happen post-scheduling because the scheduler currently doesn't care to reorder HALT instructions with respect to other instructions, and the NORMAL predicate would cause the results of subsequent derivative computations to become undefined -- If the scheduler didn't reorder HALT instructions it would actually be safe to switch to NORMAL because the behavior of derivative computations after a non-uniform discard statement is undefined by the GLSL spec, but that would make the optimization implemented by one of the following commits somewhat more difficult.

* i965/fs: Drop bogus writemasking disable bit from HALT instructions.Francisco Jerez2016-08-181-4/+0
| | | | | | | | | | This may have been the reason people ran into problems with non-uniform HALT instructions and ended up using the inefficient ANY16H/ANY8H predicates instead of ANY4H or NORMAL in order to prevent non-uniform discard. The HALT instruction is able to handle non-uniform execution masks just fine. Reviewed-by: Jason Ekstrand <[email protected]>
