[Mesa-dev] [PATCH 03/13] gallium/util: add threaded_context as a pipe_context wrapper
Marek Olšák
maraeo at gmail.com
Fri May 12 19:05:04 UTC 2017
From: Marek Olšák <marek.olsak at amd.com>
v2: - rename num_calls -> num_call_slots (for tc_call)
- rename num_calls -> num_total_call_slots (for tc_batch)
- rename num_offloaded/direct_calls -> num_offloaded/direct_slots
- declare slot[0] instead of slot[1]
- remove no-op leftover code from tc_draw_vbo
- use tc_set_resource_reference to fill threaded_transfer
- fix map flags for sparse buffers
- cosmetic changes

+
+/* This is a wrapper for pipe_context that executes all pipe_context calls
+ * in another thread.
+ *
+ *
+ * Guidelines for adopters and deviations from Gallium
+ * ---------------------------------------------------
+ *
+ * 1) pipe_context is wrapped. pipe_screen isn't wrapped. All pipe_screen
+ * driver functions that take a context (fence_finish, texture_get_handle)
+ * should manually unwrap pipe_context by doing:
+ * pipe = threaded_context_unwrap_sync(pipe);
+ *
+ * pipe_context::priv is used to unwrap the context, so drivers and state
+ * trackers shouldn't use it.
+ *
+ * No other objects are wrapped.
+ *
+ * 2) Drivers must subclass and initialize these structures:
+ * - threaded_resource for pipe_resource (use threaded_resource_init/deinit)
+ * - threaded_query for pipe_query (zero memory)
+ * - threaded_transfer for pipe_transfer (zero memory)
+ *
+ * 3) The threaded context must not be enabled for contexts that can use video
+ * codecs.
+ *
+ * 4) Changes in driver behavior:
+ * - begin_query and end_query always return true; return values from
+ * the driver are ignored.
+ * - generate_mipmap uses is_format_supported to determine success;
+ * the return value from the driver is ignored.
+ * - resource_commit always returns true; failures are ignored.
+ * - If a non-async debug callback is set, the threaded context keeps using
+ * asynchronous execution. This is OK for shader-db, but the driver
+ * shouldn't use the debug callback in any other way.
+ *
+ *
+ * Thread-safety requirements on context functions
+ * -----------------------------------------------
+ *
+ * These pipe_context functions are executed directly, so they shouldn't use
+ * pipe_context in an unsafe way. They are de-facto screen functions now:
+ * - create_query
+ * - create_batch_query
+ * - create_*_state (all CSOs and shaders)
+ * - Make sure the shader compiler doesn't use any per-context stuff.
+ * (e.g. LLVM target machine)
+ * - Only pipe_context's debug callback for shader dumps is guaranteed to
+ * be up to date, because set_debug_callback synchronizes execution.
+ * - create_surface
+ * - surface_destroy
+ * - create_sampler_view
+ * - sampler_view_destroy
+ * - stream_output_target_destroy
+ * - transfer_map (only unsychronized buffer mappings)
+ * - get_query_result (when threaded_query::flushed == true)
+ *
+ * Create calls causing a sync that can't be async due to driver limitations:
+ * - create_stream_output_target
+ *
+ *
+ * Transfer_map rules for buffer mappings
+ * --------------------------------------
+ *
+ * 1) If transfer_map has PIPE_TRANSFER_UNSYNCHRONIZED, the call is made
+ * in the non-driver thread without flushing the queue. The driver will
+ * receive TC_TRANSFER_MAP_THREADED_UNSYNC in addition to PIPE_TRANSFER_-
+ * UNSYNCHRONIZED to indicate this.
+ * Note that transfer_unmap is always enqueued and called from the driver
+ * thread.
+ *
+ * 2) The driver isn't allowed to infer unsychronized mappings by tracking
+ * the valid buffer range. The threaded context always sends TC_TRANSFER_-
+ * MAP_IGNORE_VALID_RANGE to indicate this. Ignoring the flag will lead
+ * to failures.
+ * The threaded context does its own detection of unsynchronized mappings.
+ *
+ * 3) The driver isn't allowed to do buffer invalidations by itself under any
+ * circumstances. This is necessary for unsychronized maps to map the latest
+ * version of the buffer. (because invalidations can be queued, while
+ * unsychronized maps are not queued and they should return the latest
+ * storage after invalidation). The threaded context always sends
+ * TC_TRANSFER_MAP_NO_INVALIDATE into transfer_map and buffer_subdata to
+ * indicate this. Ignoring the flag will lead to failures.
+ * The threaded context uses its own buffer invalidation mechanism.
+ *
+ *
+ * Additional requirements
+ * -----------------------
+ *
+ * get_query_result:
+ * If threaded_query::flushed == true, get_query_result should assume that
+ * it's called from a non-driver thread, in which case the driver shouldn't
+ * use the context in an unsafe way.
+ *
+ * replace_buffer_storage:
+ * The driver has to implement this callback, which will be called when
+ * the threaded context wants to replace a resource's backing storage with
+ * another resource's backing storage. The threaded context uses it to
+ * implement buffer invalidation. This call is always queued.
+ *
+ *
+ * Performance gotchas
+ * -------------------
+ *
+ * Buffer invalidations are done unconditionally - they don't check whether
+ * the buffer is busy. This can cause drivers to have more live allocations
+ * and CPU mappings than necessary.
+ *
+ *
+ * How it works (queue architecture)
+ * ---------------------------------
+ *
+ * There is a multithreaded queue consisting of batches, each batch consisting
+ * of call slots. Each call slot consists of an 8-byte header (call ID +
+ * call size + constant 32-bit marker for integrity checking) and an 8-byte
+ * body for per-call data. That is 16 bytes per call slot.
+ *
+ * Simple calls such as bind_xx_state(CSO) occupy only one call slot. Bigger
+ * calls occupy multiple call slots depending on the size needed by call
+ * parameters. That means that calls can have a variable size in the batch.
+ * For example, set_vertex_buffers(count = any, buffers = NULL) occupies only
+ * 1 call slot, but set_vertex_buffers(count = 5) occupies 6 call slots.
+ * Even though the first call slot can use only 8 bytes for data, additional
+ * call slots used by the same call can use all 16 bytes for data.
+ * For example, a call using 2 call slots has 24 bytes of space for data.
+ *
+ * Once a batch is full and there is no space for the next call, it's flushed,
+ * meaning that it's added to the queue for execution in the other thread.
+ * The batches are ordered in a ring and reused once they are idle again.
+ * The batching is necessary for low queue/mutex overhead.
+ *
