sample/mdev/mbochs: remove set but not used variable 'mdev_state'

2019-07-02T17:44:15Z

Fixes gcc '-Wunused-but-set-variable' warning: samples/vfio-mdev/mbochs.c: In function mbochs_ioctl: samples/vfio-mdev/mbochs.c:1188:21: warning: variable mdev_state set but not used [-Wunused-but-set-variable] It's not used any more since commit 104c7405a64d ("vfio: add edid support to mbochs sample driver") Signed-off-by: YueHaibing Signed-off-by: Alex Williamson

samples/vfio-mdev/mbochs: expand minor range when registering chrdev region

2019-02-12T20:21:05Z

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 Signed-off-by: Alex Williamson

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

convert mbochs_region_vm_fault and mbochs_dmabuf_vm_fault to return vm_fault_t type. Signed-off-by: Souptick Joarder Signed-off-by: Alex Williamson

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/mdev/mbochs: remove mbochs_kmap_atomic_dmabuf

2018-06-26T06:27:22Z

Atomic mapping interface for dmabufs will be removed. 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
