[PATCH 2/9] async: Introduce kfence, a N:M completion mechanism

Completions are a simple synchronization mechanism, suitable for 1:M barriers where many waiters maybe waiting for a single event. In situations where a single waiter needs to wait for multiple events they could wait on a list of individual completions. If many waiters need the same set of

[PATCH 3/3] uvcvideo: add a metadata device node

Some UVC video cameras contain metadata in their payload headers. This patch extracts that data, skipping the standard part of the header, on both bulk and isochronous endpoints and makes it available to the user space on a separate video node, using the V4L2_CAP_META_CAPTURE capability and the

[PATCH 0/3] uvcvideo: a cosmetic fix and 2 new features

Hi Laurent, The first patch in the series fixes a warning, introduced by a recent framework change. Maybe you already have a similar one in your queue, drop this one then, please. Patch 2/3 implements support for asynchronous controls, using V4L2 events. Patch 3/3 adds a metadata device node

[PATCH 1/3] uvcvideo: initialise the entity function field

Since a recent commit: [media] media-device: move media entity register/unregister functions drivers have to set entity function before registering an entity. Fix the uvcvideo driver to comply with this. Signed-off-by: Guennadi Liakhovetski ---

[PATCH 2/3] uvcvideo: send a control event when a Control Change interrupt arrives

UVC defines a method of handling asynchronous controls, which sends a USB packet over the interrupt pipe. This patch implements support for such packets by sending a control event to the user. Since this can involve USB traffic and, therefore, scheduling, this has to be done in a work queue.

[PATCH 4/9] async: Extend kfences for listening on DMA fences

dma-buf provides an interfaces for receiving notifications from DMA hardware. kfence provides a useful interface for collecting such fences and combining them with other events. Signed-off-by: Chris Wilson Cc: Sumit Semwal Cc: Shuah Khan

[PATCH 9/9] async: Introduce a dependency resolver for parallel execution

A challenge in driver initialisation is the coordination of many small sometimes independent, sometimes interdependent tasks. We would like to schedule the independent tasks for execution in parallel across as many cores as possible for rapid initialisation, and then schedule all the dependent

[PATCH 3/9] async: Extend kfence to allow struct embedding

Provide a kfence_init() function for use for embedding the kfence into a parent structure. kfence_init() takes an optional function pointer argument should the caller wish to be notified when the kfence is complete. This is useful for allowing the kfences to drive other state machinery.

[PATCH 5/9] async: Wrap hrtimer to provide a time source for a kfence

[PATCH 7/9] async: Add support for explicit fine-grained barriers

The current async-domain model supports running a multitude of independent tasks with a coarse synchronisation point. This is sufficient for its original purpose of allowing independent drivers to run concurrently during various phases (booting, early resume, late resume etc), and keep the

[PATCH 6/9] async: Add a convenience wrapper for waiting on implicit dma-buf

[PATCH 8/9] async: Add execution barriers

A frequent mode of operation is fanning out N tasks to execute in parallel, collating results, fanning out M tasks, rinse and repeat. This is also common to the notion of the async/sync kernel domain split. A barrier provides a mechanism by which all work queued after the barrier must wait (i.e.
