treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45+00:00

Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have MODULE_LICENCE("GPL*") inside which was used in the initial
   scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

  GPL-2.0-only

virtio: wrap find_vqs

2017-05-02T20:41:42+00:00

We are going to add more parameters to find_vqs, let's wrap the call so
we don't need to tweak all drivers every time.

virtio: allow drivers to request IRQ affinity when creating VQs

2017-02-27T18:54:04+00:00

Add a struct irq_affinity pointer to the find_vqs methods, which if set
is used to tell the PCI layer to create the MSI-X vectors for our I/O
virtqueues with the proper affinity from the start.  Compared to after
the fact affinity hints this gives us an instantly working setup and
allows to allocate the irq descritors node-local and avoid interconnect
traffic.  Last but not least this will allow blk-mq queues are created
based on the interrupt affinity for storage drivers.

virtio: make find_vqs() checkpatch.pl-friendly

2016-01-12T18:47:06+00:00

checkpatch.pl wants arrays of strings declared as follows:

  static const char * const names[] = { "vq-1", "vq-2", "vq-3" };

Currently the find_vqs() function takes a const char *names[] argument
so passing checkpatch.pl's const char * const names[] results in a
compiler error due to losing the second const.

This patch adjusts the find_vqs() prototype and updates all virtio
transports.  This makes it possible for virtio_balloon.c, virtio_input.c,
virtgpu_kms.c, and virtio_rpmsg_bus.c to use the checkpatch.pl-friendly
type.

virtio-input: reset device and detach unused during remove

2015-08-06T07:40:35+00:00

Spec requires a device reset during cleanup, so do it and avoid warn
in virtio core. And detach unused buffers to avoid memory leak.

Add virtio-input driver.

2015-03-29T01:43:52+00:00

virtio-input is basically evdev-events-over-virtio, so this driver isn't
much more than reading configuration from config space and forwarding
incoming events to the linux input layer.
