drm/virtio: Drop deprecated load/unload initialization

2019-01-09T08:38:49Z

Move the code around so the driver is probed the bus .probe and removed from the bus .remove callbacks. This commit is just a cleanup and shouldn't affect functionality.

drm/virtio: fix memory leak of vfpriv on error return path

2018-11-14T13:21:03Z

The allocation for vfpriv is being leaked on an error return path, fix this by kfree'ing it before returning.

drm/virtio: Use IDAs more efficiently

0-based IDAs are more efficient than any other base. Convert the 1-based IDAs to be 0-based. Signed-off-by: Matthew Wilcox Link: http://patchwork.freedesktop.org/patch/msgid/20181030165352.13065-2-willy@infradead.org Signed-off-by: Gerd Hoffmann

drm/virtio: Handle context ID allocation errors

2018-10-29T21:50:55Z

It is possible to run out of memory while allocating IDs. The current code would create a context with an invalid ID; change it to return -ENOMEM to userspace.

drm/virtio: Replace IDRs with IDAs

2018-10-29T21:50:55Z

These IDRs were only being used to allocate unique numbers, not to look up pointers, so they can use the more space-efficient IDA instead.

virtgpu: remove redundant task_comm copying

drm: Remove drm_device->virtdev

2017-05-29T18:57:25Z

This is a leftover from the drm_bus days, where we've had a bus-specific device type for every bus type in drm_device. Except for pci (which we can't remove because dri1 drivers) this is all gone. And the virt driver also doesn't really need it, dev_to_virtio works perfectly fine.
