* ddebug: rewrite to always use a threaded approachNicolai Hähnle2017-11-094-515/+546
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has multiple goals: 1. Off-load the writing of records in 'always' mode to another thread for performance. 2. Allow using ddebug with threaded contexts. This really forces us to move some of the "after_draw" handling into another thread. 3. Simplify the different modes of ddebug, both in the code and in the user interface, i.e. GALLIUM_DDEBUG. In particular, there's no 'pipelined' anymore, since we're always pipelined; and 'noflush' is replaced by 'flush', since we no longer flush by default. 4. Fix the fences in pipelining mode. They previously relied on writes via pipe_context::clear_buffer. However, on radeonsi, those could (quite reasonably) end up in the SDMA buffer. So we use the newly added PIPE_FLUSH_{TOP,BOTTOM}_OF_PIPE fences instead. 5. Improve pipelined mode overall, using the finer grained information provided by the new fences. Overall, the result is that pipelined mode should be more useful, and using ddebug in default mode is much less invasive, in the sense that it changes the overall driver behavior less (which is kind of crucial for a driver debugging tool). An example of the new hang debug output: Gallium debugger active. Hang detection timeout is 1000ms. GPU hang detected, collecting information... Draw # driver prev BOP TOP BOP dump file ------------------------------------------------------------- 2 YES YES YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000000 3 YES NO YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000001 4 YES NO YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000002 5 YES NO YES NO /home/nha/ddebug_dumps/shader_runner_19919_00000003 Done. We can see that there were almost certainly 4 draws in flight when the hang happened: the top-of-pipe fence was signaled for all 4 draws, the bottom-of-pipe fence for none of them. In virtually all cases, we'd expect the first draw in the list to be at fault, but due to the GPU parallelism, it's possible (though highly unlikely) that one of the later draws causes a component to get stuck in a way that prevents the earlier draws from making progress as well. (In the above example, there were actually only 3 draws truly in flight: the last draw is a blit that waits for the earlier draws; however, its top-of-pipe fence is emitted before the cache flush and wait, and so the fact that the draw hasn't truly started yet can only be seen from a closer inspection of GPU state.)

| | | | | | | | | | | The driver uses (and must use) the flushed flag of queries as a hint that it does not have to check for synchronization with currently queued up commands.

* winsys/amdgpu: handle cs_add_fence_dependency for deferred/unsubmitted fencesNicolai Hähnle2017-11-094-12/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea is to fix the following interleaving of operations that can arise from deferred fences: Thread 1 / Context 1 Thread 2 / Context 2 -------------------- -------------------- f = deferred flush <------- application-side synchronization -------> fence_server_sync(f) ... flush() flush() We will now stall in fence_server_sync until the flush of context 1 has completed. This scenario was unlikely to occur previously, because applications seem to be doing Thread 1 / Context 1 Thread 2 / Context 2 -------------------- -------------------- f = glFenceSync() glFlush() <------- application-side synchronization -------> glWaitSync(f) ... and indeed they probably *have* to use this ordering to avoid deadlocks in the GLX model, where all GL operations conceptually go through a single connection to the X server. However, it's less clear whether applications have to do this with other WSI (i.e. EGL). Besides, even this sequence of GL commands can be translated into the Gallium-level sequence outlined above when Gallium threading and asynchronous flushes are used. So it makes sense to be more robust. As a side effect, we no longer busy-wait on submission_in_progress. We won't enable asynchronous flushes on radeon, but add a cs_add_fence_dependency stub anyway to document the potential issue. Reviewed-by: Marek Olšák <[email protected]>
* gallium: add PIPE_FLUSH_{TOP,BOTTOM}_OF_PIPE bitsNicolai Hähnle2017-11-092-0/+16
| | | | | | | | | | | | | | | | These bits are intended to be used by the ddebug hang detection and are named in analogy to the Vulkan stage bits (and the corresponding Radeon pipeline event). Hang detection needs fences on the granularity of individual commands, which nothing else really covers. The closest alternative would have been PIPE_QUERY_GPU_FINISHED, but (a) queries are a per-context object and we really want a per-screen object, (b) queries don't offer a wait with timeout, and (c) in any case, PIPE_QUERY_GPU_FINISHED is meant to imply that GPU caches are flushed, which the new bits explicitly aren't.

* radeonsi: always use async compiles when creating shader/compute statesNicolai Hähnle2017-11-092-34/+50
| | | | | | | | | | | | | | With Gallium threaded contexts, creating shader/compute states is effectively a screen operation, so we should not use context state. In particular, this allows us to avoid using the context's LLVM TargetMachine. This isn't an issue yet because u_threaded_context filters out non-async debug callbacks, and we disable threaded contexts for debug contexts. However, we may want to change that in the future.

* gallium: clarify the constraints on sampler_view_destroyNicolai Hähnle2017-11-092-6/+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.
