* glx: Avoid atof() when computing the server's GLX versionAdam Jackson2019-09-191-1/+2
| | | | | | | | | | | atof() is locale-dependent (sigh), which means 1.3 becomes 1.0 if the locale's decimal separator isn't a full-stop. Just use the protocol major/minor instead. This would be slightly broken if the server generically implements 1.3+ but a particular screen is only capable of less, but in practice no such servers exist.

* nir/algebraic: Do not apply late DPH optimization in vertex processing stagesIan Romanick2019-09-191-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some shaders do not use 'invariant' in vertex and (possibly) geometry shader stages on some outputs that are intended to be invariant. For various reasons, this optimization may not be fully applied in all shaders used for different rendering passes of the same geometry. This can result in Z-fighting artifacts (at best). For now, disable this optimization in these stages. In tessellation stages applications seem to use 'precise' when necessary, so allow the optimization in those stages.

* iris: Rework iris_update_draw_parameters to be more efficientKenneth Graunke2019-09-183-40/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | This improves a couple of things: 1. We now only update anything if the shader actually cares. Previously, is_indexed_draw was causing us to flag dirty vertex buffers, elements, and SGVs every time the shader switched between indexed and non-indexed draws. This is a very common situation, but we only need that information if the shader uses gl_BaseVertex. We were also flagging things when switching between indirect/direct draws as well, and now we only bother if it matters. 2. We upload new draw parameters only when necessary. When we detect that the draw parameters have changed, we upload a new copy, and use that. Previously we were uploading it every time the vertex buffers were dirty (for possibly unrelated reasons) and the shader needed that info. Tying these together also makes the code a bit easier to follow. In Civilization VI's benchmark, this code was flagging dirty state many times per frame (49 average, 16 median, 614 maximum). Now it occurs exactly once for the entire run.

| | | | | | | | | | | This makes use of the total job size limiting feature added in the previous patch.

* util/u_queue: track job size and limit the size of queue growthTimothy Arceri2019-09-199-13/+28
| | | | | | | | | | | | | | | | | | | | | When both UTIL_QUEUE_INIT_RESIZE_IF_FULL and UTIL_QUEUE_INIT_USE_MINIMUM_PRIORITY are set, we can get into a situation where the queue never executes and grows to a huge size due to all other threads being busy. This is the case with the shader cache when attempting to compile a huge number of shaders up front. If all threads are busy compiling shaders the cache queues memory use can climb into the many GBs very fast. The use of these two flags with the shader cache is intended to allow shaders compiled at runtime to be compiled as fast as possible. To avoid huge memory use but still allow the queue to perform optimally in the run time compilation case, we now add the ability to track memory consumed by the jobs in the queue and limit it to a hardcoded 256MB which should be more than enough.

* util/disk_cache: bump thread count assigned to disk cache queueTimothy Arceri2019-09-191-3/+7
| | | | | | | | | | | | | | | Since we set the UTIL_QUEUE_INIT_USE_MINIMUM_PRIORITY flag this should have little impact on low core systems. However just about all modern CPUs currently available that run Mesa have *at least* 4 cores. For these CPUs allowing more threads can result in the queue being processed faster and avoid excessive memory use due to a backlog of cache entrys building up in the queue. This change helps avoid a huge build up of cache entrys in the queue due to using both the UTIL_QUEUE_INIT_USE_MINIMUM_PRIORITY and UTIL_QUEUE_INIT_RESIZE_IF_FULL flags.

This is probably desirable though, as we'd like the backend to be able to re-pull pushed data to break up long live ranges in response to register pressure. Here we simply add a "are there any pull loads at all" boolean to prog_data, which is a bit crude but at least allows us to skip work in the common "everything pushed" case. We could skip more work by tracking exactly which UBO surfaces are pulled in a bitmask, but I wanted to avoid bringing back the old mark_surface_used() mechanism. Finer-grained tracking could allow us to skip a bit more work when multiple UBOs are in use and /some/ are 100% pushed, but others are accessed via pulls. However, I'm not sure how common this is and it would save at most 4 pull descriptors, so we defer that for now. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* iris: Track per-stage bind history, reduce work accordinglyKenneth Graunke2019-09-184-6/+16
| | | | | | | | | | | | | | We now track per-stage bind history for constant and shader buffers, shader images, and sampler views by adding an extra res->bind_stages field to go with res->bind_history. This lets us flag IRIS_DIRTY_CONSTANTS for only the specific stages involved, and also skip some CPU overhead in iris_rebind_buffer. Cuts 4% of 3DSTATE_CONSTANT_XS packets in a Shadow of Mordor trace on Icelake. Reviewed-by: Caio Marcelo de Oliveira Filho <[email protected]>
* iris: Don't flag IRIS_DIRTY_BINDINGS for constant usage historyKenneth Graunke2019-09-181-2/+1
| | | | | | | | | | | | | | | | | | | The underlying buffer isn't changing - so we don't need to update any SURFACE_STATE descriptors - we just might have new constants, meaning we need to re-emit 3DSTATE_CONSTANT_XS. On Gen9, this means we need to update 3DSTATE_BINDING_TABLE_POINTERS_XS too, but that's now handled by the explicit check in the previous patch. On Gen9, this should cause us to re-emit the binding table /pointer/ on writing to a buffer with PIPE_BIND_CONSTANT_BUFFER, rather than emitting a whole new /table/. On Gen8 and Gen11, this avoids binding table churn altogether. Cuts 61% of 3DSTATE_BINDING_TABLE_POINTERS_XS packets in a Shadow of Mordor trace on Icelake.

* iris: Explicitly emit 3DSTATE_BTP_XS on Gen9 with DIRTY_CONSTANTS_XSKenneth Graunke2019-09-181-1/+6
| | | | | | | | | | | | | Right now, we usually flag both IRIS_DIRTY_{CONSTANTS,BINDINGS}_XS, because we have SURFACE_STATE for constant buffers in case the shaders access them via pull mode. But this flagging is overkill in many cases. Gen8 and Gen11 don't need it at all. Gen9 doesn't need that large of a hammer in all cases. Just handle it explicitly so the right thing happens.

* nir/opt_if: Fix undef handling in opt_split_alu_of_phi()Connor Abbott2019-09-181-55/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pass assumed that "Most ALU ops produce an undefined result if any source is undef" which is completely untrue. Due to how we lower if statements to selects and then optimize on those selects later, we simply cannot make that assumption. In particular this pass tried to replace an ior of undef and true, which had been generated by optimizing a select which itself came from flattening an if statement, to undef causing a miscompilation for a CTS test with radeonsi NIR. We fix this by always doing what the non-undef path did, i.e. duplicate the instruction twice. If there are cases where the instruction before the loop can be folded away due to having an undef source, we should add these to opt_undef instead. The comment above the pass says that if the phi source from before the loop is undef, and we can fold the instruction before the loop to undef, then we can ignore sources of the original instruction that don't dominate the block before the loop because we don't need them to create the instruction before the loop. This is incorrect, because the instruction at the bottom of the loop would get those sources from the wrong loop iteration. The code never actually did what the comment said, so we only have to update the comment to match what the pass actually does. We also update the example to more closely match what most actual loops look like after vtn and peephole_select. There are no shader-db changes with i965, radeonsi NIR, or radv. With anv and my vkpipeline-db there's only one change: total instructions in shared programs: 14125290 -> 14125300 (<.01%) instructions in affected programs: 2598 -> 2608 (0.38%) helped: 0 HURT: 1 total cycles in shared programs: 2051473437 -> 2051473397 (<.01%) cycles in affected programs: 36697 -> 36657 (-0.11%) helped: 1 HURT: 0 Fixes KHR-GL45.shader_subroutine.control_flow_and_returned_subroutine_values_used_as_subroutine_input with radeonsi NIR.
