Otherwise it could be added more than once.
Note that the deleted comment is wrong: between when d3d12_command_queue_flush_ops() returns and when the queue is added back to the blocked list, the queue might have been pushed to and flushed an arbitrary number of times. --- libs/vkd3d/command.c | 51 ++++++++++++++++++-------------------------- 1 file changed, 21 insertions(+), 30 deletions(-)

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 | 138 ++++++++++++++++--------------------------- 1 file changed, 52 insertions(+), 86 deletions(-)

From: Giovanni Mascellani gmascellani@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 | 141 +++++++++++++++++++++++++++---------- libs/vkd3d/vkd3d_private.h | 9 +++ 2 files changed, 111 insertions(+), 39 deletions(-)

We could certainly deprecate it. I don't think we can make it go away completely, other than in the sense of "Returns VK_NULL_HANDLE when VKD3D_API_VERSION_1_8 or higher is specified.", or something along those lines.
That still means that a client compiled with vkd3d 1.7 and running with vkd3d 1.8 would receive a valid handle, right? So even in vkd3d 1.8 we still have to support a code path without the CS thread. It requires some more code, but it should be doable.
Right, or even an application/library compiled against vkd3d 1.8 but specifying VKD3D_API_VERSION_1_7 or lower.

Not a huge issue, but for consistency I think this should be something like `d3d12_command_queue_record_as_blocked()`. We have `d3d12_command_list_mark_as_invalid()`, `d3d12_query_heap_mark_result_as_available()`, and `d3d12_device_mark_as_removed()`, all of which mark the object itself in some way, which `mark_as_blocked()` doesn't do.

`d3d12_command_queue_flush_ops()` still returns `true` in a couple of places.

Already added near the top of the file.

This would be more accurately named something like `d3d12_command_queue_swap_op_arrays()`.

It would be neater to introduce a new struct, e.g. `d3d12_command_queue_op_array`, with helpers to perform initialisation, allocation and cleanup. The swap operation could then be three lines.

This didn't occur while testing in SotTR, Control and GRID 2019, so it could be changed to a fixme. There's always the risk of fixme spam in another game but that will be solved by later patches.
This all looks good once my comments are addressed.

The Medium sometimes hits `ops_count` and sometimes `is_flushing`, so I'd leave both as `WARN`.
