	Actually, total amount of available minor number for a single major is MINORMARK + 1. So expand minor range when registering chrdev region. Signed-off-by: Chengguang Xu <cgxu519@gmx.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2018-10-11	vfio: add edid support to mbochs sample driver	Gerd Hoffmann	1	-19/+117

2018-07-11	sample: vfio-mdev: avoid deadlock in mdev_access()	Alexey Khoroshilov	1	-1/+3
	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 <khoroshilov@ispras.ru> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2018-07-04	sample/vfio-mdev: Change return type to vm_fault_t	Souptick Joarder	1	-2/+2
	convert mbochs_region_vm_fault and mbochs_dmabuf_vm_fault to return vm_fault_t type. Signed-off-by: Souptick Joarder <jrdr.linux@gmail.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2018-06-26	sample/mdev/mbochs: add mbochs_kunmap_dmabuf	Gerd Hoffmann	1	-0/+7
	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 <kraxel@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2018-06-26	sample/mdev/mbochs: remove mbochs_kmap_atomic_dmabuf	Gerd Hoffmann	1	-10/+0
	Atomic mapping interface for dmabufs will be removed. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2018-06-08	sample: vfio bochs vbe display (host device for bochs-drm)	Gerd Hoffmann	1	-0/+1406
	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 <kraxel@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
