virtio: Add module driver macro for virtio drivers.

2013-02-13T06:30:32Z

Add helper macro for drivers that don't do anything special in module init/exit. Signed-off-by: Sjur Brændeland Signed-off-by: Rusty Russell

virtio: make config_ops const

2013-02-11T05:02:17Z

It is just a table of function pointers, make it const for cleanliness and security reasons. Signed-off-by: Stephen Hemminger Signed-off-by: Rusty Russell

virtio: add drv_to_virtio to make code clearly

2012-12-18T04:50:43Z

Add drv_to_virtio wrapper to get virtio_driver from device_driver. Cc: Rusty Russell Cc: "Michael S. Tsirkin" Signed-off-by: Wanlong Gao Signed-off-by: Rusty Russell

virtio: use dev_to_virtio wrapper in virtio

2012-12-18T04:50:42Z

Use dev_to_virtio wrapper in virtio to make code clearly. Cc: Rusty Russell Cc: "Michael S. Tsirkin" Signed-off-by: Wanlong Gao Signed-off-by: Rusty Russell

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

2012-12-18T04:50:31Z

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. Acked-by: Michael S. Tsirkin Signed-off-by: Rusty Russell

virtio-ring: move queue_index to vring_virtqueue

2012-09-28T05:35:15Z

Instead of storing the queue index in transport-specific virtio structs, this patch moves them to vring_virtqueue and introduces an helper to get the value. This lets drivers simplify their management and tracing of virtqueues. Signed-off-by: Jason Wang Signed-off-by: Paolo Bonzini Signed-off-by: Rusty Russell

[SCSI] virtio-scsi: Add vdrv->scan for post VIRTIO_CONFIG_S_DRIVER_OK LUN scanning

2012-07-20T07:59:03Z

This patch changes virtio-scsi to use a new virtio_driver->scan() callback so that scsi_scan_host() can be properly invoked once virtio_dev_probe() has set add_status(dev, VIRTIO_CONFIG_S_DRIVER_OK) to signal active virtio-ring operation, instead of from within virtscsi_probe(). This fixes a bug where SCSI LUN scanning for both virtio-scsi-raw and virtio-scsi/tcm_vhost setups was happening before VIRTIO_CONFIG_S_DRIVER_OK had been set, causing VIRTIO_SCSI_S_BAD_TARGET to occur. This fixes a bug with virtio-scsi/tcm_vhost where LUN scan was not detecting LUNs. Tested with virtio-scsi-raw + virtio-scsi/tcm_vhost w/ IBLOCK on 3.5-rc2 code.

virtio: drop thaw PM operation

2012-03-31T02:39:50Z

The thaw operation was used by the balloon driver, but after the last commit there's no reason to have separate thaw and restore callbacks. Signed-off-by: Amit Shah

virtio: pci: add PM notification handlers for restore, freeze, thaw, poweroff

2012-01-12T05:14:44Z

Handle thaw, restore and freeze notifications from the PM core. Expose these to individual virtio drivers that can quiesce and resume vq operations. For drivers not implementing the thaw() method, use the restore method instead. These functions also save device-specific data so that the device can be put in pre-suspend state after resume, and disable and enable the PCI device in the freeze and resume functions, respectively.

virtio: support unlocked queue kick

2012-01-12T05:14:43Z

Based on patch by Christoph for virtio_blk speedup: Split virtqueue_kick to be able to do the actual notification outside the lock protecting the virtqueue. This patch was originally done by Stefan Hajnoczi, but I can't find the original one anymore and had to recreated it from memory. Pointers to the original or corrections for the commit message are welcome. Stefan's patch was here: https://github.com/stefanha/linux/commit/a6d06644e3a58e57a774e77d7dc34c4a5a2e7496 http://www.spinics.net/lists/linux-virtualization/msg14616.html Third time's the charm!
