* st/mesa: guard sampler views changes with a mutexNicolai Hähnle2017-11-095-96/+250
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some locking is unfortunately required, because well-formed GL programs can have multiple threads racing to access the same texture, e.g.: two threads/contexts rendering from the same texture, or one thread destroying a context while the other is rendering from or modifying a texture. Since even the simple mutex caused noticable slowdowns in the piglit drawoverhead micro-benchmark, this patch uses a slightly more involved approach to keep locks out of the fast path: - the initial lookup of sampler views happens without taking a lock - a per-texture lock is only taken when we have to modify the sampler view(s) - since each thread mostly operates only on the entry corresponding to its context, the main issue is re-allocation of the sampler view array when it needs to be grown, but the old copy is not freed Old copies of the sampler views array are kept around in a linked list until the entire texture object is deleted. The total memory wasted in this way is roughly equal to the size of the current sampler views array. Fixes non-deterministic memory corruption in some dEQP-EGL.functional.sharing.gles2.multithread.* tests, e.g. dEQP-EGL.functional.sharing.gles2.multithread.simple.images.texture_source.create_texture_render Reviewed-by: Marek Olšák <[email protected]>

* gallium: clarify the constraints on sampler_view_destroyNicolai Hähnle2017-11-093-7/+20
| | | | | | | | | | | | | | | | | r600 expects the context that created the sampler view to still be alive (there is a per-context list of sampler views). svga currently bails when the context of destruction is not the same as creation. The GL state tracker, which is the only one that runs into the multi-context subtleties (due to share groups), already guarantees that sampler views are destroyed before their context of creation is destroyed. Most drivers are context-agnostic, so the warning message in pipe_sampler_view_release doesn't really make sense. Reviewed-by: Marek Olšák <[email protected]>

* radeonsi: use ready fences on all shaders, not just optimized onesNicolai Hähnle2017-11-093-26/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a race condition between si_shader_select_with_key and si_bind_XX_shader: Thread 1 Thread 2 -------- -------- si_shader_select_with_key begin compiling the first variant (guarded by sel->mutex) si_bind_XX_shader select first_variant by default as state->current si_shader_select_with_key match state->current and early-out Since thread 2 never takes sel->mutex, it may go on rendering without a PM4 for that shader, for example. The solution taken by this patch is to broaden the scope of shader->optimized_ready to a fence shader->ready that applies to all shaders. This does not hurt the fast path (if anything it makes it faster, because we don't explicitly check is_optimized). It will also allow reducing the scope of sel->mutex locks, but this is deferred to a later commit for better bisectability.

* u_queue: add a futex-based implementation of fencesNicolai Hähnle2017-11-092-0/+94
| | | | | | | | | | | | | | | | | Fences are now 4 bytes instead of 96 bytes (on my 64-bit system). Signaling a fence is a single atomic operation in the fast case plus a syscall in the slow case.

* glsl: Make #pragma STDGL invariant(all) only modify outputs.Kenneth Graunke2017-11-081-24/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the GLSL ES 3.20, GLSL 4.50, and GLSL 1.20 specs: "To force all output variables to be invariant, use the pragma #pragma STDGL invariant(all) before all declarations in a shader." Notably, this is only supposed to affect output variables. Furthermore, "Only variables output from a shader can be candidates for invariance." It looks like this has been wrong since we first supported the pragma in 2011 (commit 86b4398cd158024f6be9fa830554a11c2a7ebe0c). Fixes dEQP-GLES2.functional.shaders.preprocessor.pragmas.pragma_fragment. v2: Now that all cases are identical (other than compute shaders, which have no output variables anyway), we can drop the switch statement entirely. We also don't need the current_function == NULL check; this was a hold over from when we had a single var_mode_out for both function parameters and shader varyings, in the bad old days.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While modern pthread mutexes are very fast, they still incur a call to an external DSO and overhead of the generality and features of pthread mutexes. Most mutexes in mesa only needs lock/unlock, and the idea here is that we can inline the atomic operation and make the fast case just two intructions. Mutexes are subtle and finicky to implement, so we carefully copy the implementation from Ulrich Dreppers well-written and well-reviewed paper: "Futexes Are Tricky" http://www.akkadia.org/drepper/futex.pdf We implement "mutex3", which gives us a mutex that has no syscalls on uncontended lock or unlock. Further, the uncontended case boils down to a cmpxchg and an untaken branch and the uncontended unlock is just a locked decr and an untaken branch. We use __builtin_expect() to indicate that contention is unlikely so that gcc will put the contention code out of the main code flow. A fast mutex only supports lock/unlock, can't be recursive or used with condition variables. We keep the pthread mutex implementation around as for the few places where we use condition variables or recursive locking. For platforms or compilers where futex and atomics aren't available, simple_mtx_t falls back to the pthread mutex. The pthread mutex lock/unlock overhead shows up on benchmarks for CPU bound applications. Most CPU bound cases are helped and some of our internal bind_buffer_object heavy benchmarks gain up to 10%.

| | | | | | | | | | | | | | | | When I introduced gl_shader_program_data one of the intentions was to fix a bug where a failed linking attempt freed data required by a currently active program. However I seem to have failed to finish hooking up the final steps required to have the data hang around. Here we create a fresh instance of gl_shader_program_data every time we link. gl_program has a reference to gl_shader_program_data so it will be freed once the program is no longer active.

| | | | | | | | | | | | | | | | | | | | | | | | | This has a bit of a surprising effect: For the render pipeline, the upload_sampler_state_table atom emits 3DSTATE_BINDING_TABLE_POINTERS_XS. It tries to avoid this for compute: if (GEN_GEN >= 7 && stage_state->stage != MESA_SHADER_COMPUTE) { /* Emit a 3DSTATE_SAMPLER_STATE_POINTERS_XS packet. */ genX(emit_sampler_state_pointers_xs)(brw, stage_state); } ... However, we were failing to initialize brw->cs.base.stage, so it was left as 0 (MESA_SHADER_VERTEX), causing this condition to break. We then emitted 3DSTATE_SAMPLER_STATE_POINTERS_VS in GPGPU mode, when trying to upload CS samplers. Nothing good can come of this. Found by inspection while debugging a GPU hang.
