[PATCH v5 0/4] MR94: Fix other synchronization problems
-- v5: vkd3d: Do not keep the CS queue locked while processing it. vkd3d: Always enqueue CS operations, even if they can be executed right away. vkd3d: Hold the queue mutex when adding the queue to a blocked list. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/94

From: Giovanni Mascellani <gmascellani(a)codeweavers.com> The goal is to simplify the CS queue handling: with this change operations are always started by d3d12_command_queue_flush_ops(), in order to make further refactoring easier. Notice that while with this change executing an operation on an empty CS queue is a bit less efficient, it doesn't require more locking. On the other hand, this change paves the road for executing CS operations without holding the queue lock. --- libs/vkd3d/command.c | 136 ++++++++++++++++--------------------------- 1 file changed, 50 insertions(+), 86 deletions(-) diff --git a/libs/vkd3d/command.c b/libs/vkd3d/command.c index c9d2f03d..dc2b184e 100644 --- a/libs/vkd3d/command.c +++ b/libs/vkd3d/command.c @@ -27,6 +27,7 @@ static void d3d12_fence_signal_timeline_semaphore(struct d3d12_fence *fence, uin static HRESULT d3d12_command_queue_signal(struct d3d12_command_queue *command_queue, struct d3d12_fence *fence, uint64_t value);

From: Giovanni Mascellani <gmascellani(a)codeweavers.com> d3d12_command_queue_flush_ops() can renter itself while processing signal events. Since we don't use recursive mutexes, we currently have to check some of the queue variables without holding the mutex, which is not safe. This is solved by allowing the queue to release its mutex while it is processing entries: when flushing, the queue is briefly locked, the is_flushing flag is set, the queue content is copied away and the queue is unlocked again. After having processed the entries, the queue is locked again to check is something else was added in the meantime. This is repeated until the queue is empty (or a wait operation is blocking it). This should also remove some latency when a thread pushes to the queue while another one is processing it, but I didn't try to measure any impact. While it is expected that with this patch the queue mutex will be locked and unlocked more frequently, it should also remain locked for less time, hopefully creating little contention. --- libs/vkd3d/command.c | 173 +++++++++++++++++++++++++------------ libs/vkd3d/vkd3d_private.h | 18 +++- 2 files changed, 131 insertions(+), 60 deletions(-) diff --git a/libs/vkd3d/command.c b/libs/vkd3d/command.c index dc2b184e..171aaa3a 100644 --- a/libs/vkd3d/command.c +++ b/libs/vkd3d/command.c @@ -5994,6 +5994,11 @@ static ULONG STDMETHODCALLTYPE d3d12_command_queue_AddRef(ID3D12CommandQueue *if return refcount; } +static void d3d12_command_queue_op_array_destroy(struct d3d12_command_queue_op_array *array) +{ + vkd3d_free(array->ops); +} + static ULONG STDMETHODCALLTYPE d3d12_command_queue_Release(ID3D12CommandQueue *iface) { struct d3d12_command_queue *command_queue = impl_from_ID3D12CommandQueue(iface); @@ -6008,7 +6013,8 @@ static ULONG STDMETHODCALLTYPE d3d12_command_queue_Release(ID3D12CommandQueue *i vkd3d_fence_worker_stop(&command_queue->fence_worker, device); vkd3d_mutex_destroy(&command_queue->op_mutex); - vkd3d_free(command_queue->ops); + d3d12_command_queue_op_array_destroy(&command_queue->op_queue); + d3d12_command_queue_op_array_destroy(&command_queue->aux_op_queue); vkd3d_private_store_destroy(&command_queue->private_store); @@ -6079,14 +6085,6 @@ static HRESULT STDMETHODCALLTYPE d3d12_command_queue_GetDevice(ID3D12CommandQueu return d3d12_device_query_interface(command_queue->device, iid, device); } -static struct vkd3d_cs_op_data *d3d12_command_queue_require_space_locked(struct d3d12_command_queue *queue) -{ - if (!vkd3d_array_reserve((void **)&queue->ops, &queue->ops_size, queue->ops_count + 1, sizeof(*queue->ops))) - return NULL; - - return &queue->ops[queue->ops_count++]; -} - static void STDMETHODCALLTYPE d3d12_command_queue_UpdateTileMappings(ID3D12CommandQueue *iface, ID3D12Resource *resource, UINT region_count, const D3D12_TILED_RESOURCE_COORDINATE *region_start_coordinates, const D3D12_TILE_REGION_SIZE *region_sizes, @@ -6143,22 +6141,34 @@ static void d3d12_command_queue_execute(struct d3d12_command_queue *command_queu vkd3d_free(buffers); } +static bool d3d12_command_queue_op_array_reserve(struct d3d12_command_queue_op_array *array, + size_t copy_count, const struct vkd3d_cs_op_data *copy_from) +{ + if (!vkd3d_array_reserve((void **)&array->ops, &array->size, array->count + copy_count, sizeof(*array->ops))) + { + ERR("Cannot reserve memory for %zu new ops.\n", copy_count); + return false; + } + + memcpy(&array->ops[array->count], copy_from, copy_count * sizeof(*array->ops)); + array->count += copy_count; + + return true; +} + static HRESULT d3d12_command_queue_enqueue_op(struct d3d12_command_queue *queue, const struct vkd3d_cs_op_data *op) { - struct vkd3d_cs_op_data *new_op; bool flushed_any = false; vkd3d_mutex_lock(&queue->op_mutex); - if (!(new_op = d3d12_command_queue_require_space_locked(queue))) + if (!d3d12_command_queue_op_array_reserve(&queue->op_queue, 1, op)) { vkd3d_mutex_unlock(&queue->op_mutex); return E_OUTOFMEMORY; } - *new_op = *op; - - if (queue->ops_count == 1) + if (queue->op_queue.count == 1 && !queue->is_flushing) return d3d12_command_queue_flush_ops_locked(queue, &flushed_any); vkd3d_mutex_unlock(&queue->op_mutex); @@ -6723,18 +6733,52 @@ static const struct ID3D12CommandQueueVtbl d3d12_command_queue_vtbl = d3d12_command_queue_GetDesc, }; +static void d3d12_command_queue_swap_queues(struct d3d12_command_queue *queue) +{ + struct d3d12_command_queue_op_array array; + + array = queue->op_queue; + queue->op_queue = queue->aux_op_queue; + queue->aux_op_queue = array; +} + +static HRESULT d3d12_command_queue_fixup_after_flush(struct d3d12_command_queue *queue, unsigned int done_count) +{ + HRESULT hr; + + queue->aux_op_queue.count -= done_count; + memmove(queue->aux_op_queue.ops, &queue->aux_op_queue.ops[done_count], + queue->aux_op_queue.count * sizeof(*queue->aux_op_queue.ops)); + + vkd3d_mutex_lock(&queue->op_mutex); + + d3d12_command_queue_swap_queues(queue); + + if (!d3d12_command_queue_op_array_reserve(&queue->op_queue, queue->aux_op_queue.count, queue->aux_op_queue.ops)) + ERR("Cannot reallocate, dropping %zu ops.\n", queue->aux_op_queue.count); + + queue->aux_op_queue.count = 0; + queue->is_flushing = false; + + hr = d3d12_command_queue_record_as_blocked(queue); + + vkd3d_mutex_unlock(&queue->op_mutex); + + return hr; +} + static HRESULT d3d12_command_queue_flush_ops(struct d3d12_command_queue *queue, bool *flushed_any) { - if (!queue->ops_count) - return S_OK; + vkd3d_mutex_lock(&queue->op_mutex); /* This function may be re-entered when invoking * d3d12_command_queue_signal().

This all looks good once my comments are addressed. Thanks for the review. I should have addressed everything, except for the `WARN` thing.

A name like d3d12_command_queue_op_array_append() would be better for consistency. Henri commented on a similar problem in MR 84 where only the count of new elements is passed, which is not how vkd3d_array_reserve() works. -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/94#note_25749
