* freedreno: small fix for flushing dependent batchesRob Clark2018-02-101-0/+13
| | | | | | | | | | | | | | | Flush a resource's previous write_batch synchronously. Because a resource's associated batches are not updated until after the flush thread submits rendering to the kernel, this was causing a bit of confusion in the following loop. This fixes a bug that appeared with recent stk. Perhaps we need to re-work things a bit to clear out dependent patches in the ctx's thread and use a fence to deal with the period between when a flush is queued and when it is submitted to the kernel. But this will do until time permits a larger refactor. Signed-off-by: Rob Clark <[email protected]>
* freedreno/ir3: intra-block schedulingRob Clark2018-02-101-22/+104
| | | | | | | | | | | | Because of loops, we can't schedule all of a block's predecessors first. Instead just assume that the result consumed in a block was written far enough away in all paths into a block. And do an intra-block scheduling pass to figure out if there are any cases where we need to insert extra nop's. This works out better than always assuming the worst case (ie. that a value live into a block was written in the last instruction in the predecessor block).

* freedreno/ir3: account for arrays in delayslot calcRob Clark2018-02-101-2/+30
| | | | | | | | | | | | | Normally false-deps are not something to consider, since they mostly exist for delay-slot related reasons: * barriers * ordering writes after read * SSBO/image access ordering The exception is a false-dependency on an array store.

* freedreno/ir3: more clever legalize algorithmRob Clark2018-02-101-42/+96
| | | | | | | | | | | | | | Previously we didn't handle flow control in legalize, and instead just set (ss)(sy) on the first instruction in every block. Which isn't very clever. Instead, consider output state of all predecessor blocks, so we only set a sync bit if needed for any possible path leading into a block. Because of loops, we can't require that all successor blocks are legalized before a given block, so instead run in a loop until results converge. Signed-off-by: Rob Clark <[email protected]>

* freedreno/ir3: clean up dangling false-dep'sRob Clark2018-02-102-0/+46
| | | | | | | | | | | | | Maybe there is a better way for this.. where it comes useful is "array" loads, which end up as a false-dep for a later array store. If all the uses of an array load are CP'd into their consumer, it still leaves the dangling array load, leading to funny things like: mov.u32u32 r5.y, r0.y mov.u32u32 r5.y, r0.z Signed-off-by: Rob Clark <[email protected]>

* freedreno/ir3: add experimental GCM passRob Clark2018-02-101-0/+7
| | | | | | | | | | Generally seems to do worse on instruction count and register usage, according to shader-db. But shader-db also doesn't do a very good job of weighting loop bodies, so that might not be totally valid. So add an env variable to enable GCM pass for easier experimentation.

* freedreno/ir3: change opt passesRob Clark2018-02-101-0/+14

* freedreno/ir3: use peephole select passRob Clark2018-02-101-1/+1
| | | | | | | | | | | | | | | Agressively lowering all if/else to selects in some extreme cases results in much higher register pressure. Using peephole select instead with a modest threshold speeds up alu2 4x! 16 seems like a good limit, low enough to help alu2 but not too low that it penalizes everything else. With a bit better scheduling of the instruction that moves a value into a predicate register, we might be able to lower this limit a bit more in the future, but since we need 6 cycles from the move to predicate register to predicated branch, that puts some sort of lower bound on how far we can lower this threshold.

* freedreno/ir3: lower phi webs to regsRob Clark2018-02-101-2/+1
| | | | | | | | | | nir's from_ssa pass is much better at avoiding inserting extra moves than our logic is. And lowering phi webs to regs just treats anything involved in a phi web as an array of length=1. Which with previous array related fixes in RA/etc ends up working out quite well. This cuts down on extra instructions and also helps with register pressure. Signed-off-by: Rob Clark <[email protected]>

* freedreno/ir3: fix printing of relative branch offsetsRob Clark2018-02-102-3/+3
| | | | | | | | | | | | The number of bits depends on generation. But printing negative values with a5xx encoding (largest size) but compiling for a3xx or a4xx, would result in negative values printed as large positive values. I guess in practice huge negative branch offsets aren't likely (and if that is the case, the shader is probably too big to grok by reading the assembly). So just print using smallest bitfield size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v2: * Check whether the node src and dst registers are NULL before using them. * fix a type in the commit message. Two cases are handled with this patch: 1. If copy propagation tries to eliminated a move from a relative array access then it could optimize MOV R1, ARRAY[RELADDR_1] MOV R2, ARRAY[RELADDR_2] OP2 R3, R1 R2 into OP2 R3, ARRAY[RELADDR_1], ARRAY[RELADDR_2] which is forbidden, because there is only one address register available. 2. When MULADD(x,a,MUL(x,c)) is handled MUL TMP, R1, ARRAY[RELADDR_1] MULLADD R3, R1, ARRAY[RELADDR_2], TMP by folding this into ADD TMP, ARRAY[RELADDR_2], ARRAY[RELADDR_1] MUL R3, R1, TMP which is also forbidden. Test for these cases and reject the optimization if a forbidden combination of relative access would be created.
