litmus-rt-tegra.git/drivers/virtio, branch master

Patched in Tegra support.

2013-01-17T21:15:55+00:00

Drivers: virtio: remove __dev* attributes.

2013-01-03T23:57:01+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Pull virtio update from Rusty Russell:
 "Some nice cleanups, and even a patch my wife did as a "live" demo for
  Latinoware 2012.

  There's a slightly non-trivial merge in virtio-net, as we cleaned up
  the virtio add_buf interface while DaveM accepted the mq virtio-net
  patches."

virtio: add drv_to_virtio to make code clearly

Add drv_to_virtio wrapper to get virtio_driver from device_driver.

virtio-mmio: Fix irq parsing in command line parameter

2012-12-18T04:50:41+00:00

When the resource_size_t is 64-bit long, the sscanf() on
the virtio device command line paramter string may return
wrong value because its format was defined as "%u". Fixed
by using an intermediate local value of a known length.

Also added cleaned up the resource creation and added extra
comments to make the parameters parsing easier to follow.

virtio: Convert dev_printk(KERN_ to dev_(

2012-12-18T04:50:40+00:00

dev_ calls take less code than dev_printk(KERN_
and reducing object size is good.
Convert if (printk_ratelimit()) dev_printk to dev__ratelimited.

virtio: make virtqueue_add_buf() returning 0 on success, not capacity.

2012-12-18T04:50:34+00:00

Now noone relies on this behavior, we simplify virtqueue_add_buf() so it
return 0 or -errno.

virtio: move queue_index and num_free fields into core struct virtqueue.

2012-12-18T04:50:31+00:00

They're generic concepts, so hoist them.  This also avoids accessor
functions (though kept around for merge with DaveM's net tree).

This goes even further than Jason Wang's 17bb6d4088 patch
("virtio-ring: move queue_index to vring_virtqueue") which moved the
queue_index from the specific transport.

virtio-pci: use module_pci_driver to simplify the code

2012-12-18T04:50:30+00:00

Use the module_pci_driver() macro to make the code simpler
by eliminating module_init and module_exit calls.
