sample: vfio-mdev: avoid deadlock in mdev_access()

2018-07-11T19:22:41Z

mdev_access() calls mbochs_get_page() with mdev_state->ops_lock held, while mbochs_get_page() locks the mutex by itself. It leads to unavoidable deadlock. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Alex Williamson

sample/vfio-mdev: Change return type to vm_fault_t

2018-07-04T16:42:04Z

sample/mdev/mbochs: add mbochs_kunmap_dmabuf

2018-06-26T06:27:23Z

There is no default implementation for dma_buf_ops->unmap. So add a function unmapping the page, otherwise we'll leak them. Signed-off-by: Gerd Hoffmann Signed-off-by: Alex Williamson

sample: vfio bochs vbe display (host device for bochs-drm)

2018-06-08T16:24:16Z

Display device, demo-ing the vfio dmabuf display interface (VFIO_GFX_PLANE_TYPE_DMABUF). Compatible enough to qemu stdvga that bochs-drm.ko can be used as guest driver. Signed-off-by: Gerd Hoffmann Signed-off-by: Alex Williamson
