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

2018-11-14T11:50:34Z

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

2017-11-10T11:45:35Z

Remove redundant task name copying because: 1. task->comm is already NUL-terminated 2. virtio_gpu_context_create() trims passed dbgname anyway Signed-off-by: Michał Mirosław Link: http://patchwork.freedesktop.org/patch/msgid/588612bbc672e8b598e10f79fcbc041122e844ba.1504202471.git.mirq-linux@rere.qmqm.pl Signed-off-by: Gerd Hoffmann

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.

virtio: wrap find_vqs

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. Signed-off-by: Michael S. Tsirkin

virtio: allow drivers to request IRQ affinity when creating VQs

2017-02-27T18:54:04Z

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. Signed-off-by: Christoph Hellwig Reviewed-by: Jason Wang Signed-off-by: Michael S.
