config VHOST_NET tristate "Host kernel accelerator for virtio net" depends on NET && EVENTFD && (TUN || !TUN) && (MACVTAP || !MACVTAP) select VHOST ---help--- This kernel module can be loaded in host kernel to accelerate guest networking with virtio_net. Not to be confused with virtio_net module itself which needs to be loaded in guest kernel. To compile this driver as a module, choose M here: the module will be called vhost_net. config VHOST_SCSI tristate "VHOST_SCSI TCM fabric driver" depends on TARGET_CORE && EVENTFD && m select VHOST default n ---help--- Say M here to enable the vhost_scsi TCM fabric module for use with virtio-scsi guests config VHOST_VSOCK tristate "vhost virtio-vsock driver" depends on VSOCKETS && EVENTFD select VIRTIO_VSOCKETS_COMMON select VHOST default n ---help--- This kernel module can be loaded in the host kernel to provide AF_VSOCK sockets for communicating with guests. The guests must have the virtio_transport.ko driver loaded to use the virtio-vsock device. To compile this driver as a module, choose M here: the module will be called vhost_vsock. config VHOST tristate ---help--- This option is selected by any driver which needs to access the core of vhost. config VHOST_CROSS_ENDIAN_LEGACY bool "Cross-endian support for vhost" default n ---help--- This option allows vhost to support guests with a different byte ordering from host while using legacy virtio. Userspace programs can control the feature using the VHOST_SET_VRING_ENDIAN and VHOST_GET_VRING_ENDIAN ioctls. This is only useful on a few platforms (ppc64 and arm64). Since it adds some overhead, it is disabled by default. If unsure, say "N". treecommitdiff

HID: cp2112: fix sleep-while-atomic
A recent commit fixing DMA-buffers on stack added a shared transfer buffer protected by a spinlock. This is broken as the USB HID request callbacks can sleep. Fix this up by replacing the spinlock with a mutex.
