Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

vhost: allow vhost-scsi driver to be built-in

2018-08-21T22:01:32+00:00

It's useful to allow vhost-scsi to be built-in when testing vhost in L1 + L2 VMs and booting L1 VM with QEMU '-kernel' option. Signed-off-by: Greg Edwards Signed-off-by: Michael S. Tsirkin

tap: tap as an independent module

2017-02-12T01:59:41+00:00

This patch makes tap a separate module for other types of virtual interfaces, for example, ipvlan to use. Signed-off-by: Sainath Grandhi Signed-off-by: David S. Miller

vhost: split out vringh Kconfig

2016-08-02T13:54:28+00:00

vringh is pulled in by caif and mic, but the other vhost config does not need to be there. In particular, it makes no sense to have vhost net/scsi/sock under caif/mic. Create a separate Kconfig file and put vringh bits there. Signed-off-by: Michael S. Tsirkin

VSOCK: Add Makefile and Kconfig

2016-08-01T23:57:30+00:00

Enable virtio-vsock and vhost-vsock. Signed-off-by: Asias He Signed-off-by: Stefan Hajnoczi Signed-off-by: Michael S. Tsirkin

vhost: drop vringh dependency

2016-08-01T23:57:28+00:00

vringh isn't used by vhost net or scsi - it's used by CAIF only at the moment. Drop the dependency. Signed-off-by: Michael S. Tsirkin

vhost: cross-endian support for legacy devices

2015-06-01T13:48:55+00:00

This patch brings cross-endian support to vhost when used to implement legacy virtio devices. Since it is a relatively rare situation, the feature availability is controlled by a kernel config option (not set by default). The vq->is_le boolean field is added to cache the endianness to be used for ring accesses. It defaults to native endian, as expected by legacy virtio devices. When the ring gets active, we force little endian if the device is modern. When the ring is deactivated, we revert to the native endian default. If cross-endian was compiled in, a vq->user_be boolean field is added so that userspace may request a specific endianness. This field is used to override the default when activating the ring of a legacy device. It has no effect on modern devices. Signed-off-by: Greg Kurz Signed-off-by: Michael S.

vhost: Make vhost a separate module

2013-07-07T14:33:44+00:00

Currently, vhost-net and vhost-scsi are sharing the vhost core code. However, vhost-scsi shares the code by including the vhost.c file directly. Making vhost a separate module makes it is easier to share code with other vhost devices. Signed-off-by: Asias He Signed-off-by: Michael S. Tsirkin

Merge tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2013-05-02T21:14:04+00:00

Pull virtio & lguest updates from Rusty Russell: "Lots of virtio work which wasn't quite ready for last merge window. Plus I dived into lguest again, reworking the pagetable code so we can move the switcher page: our fixmaps sometimes take more than 2MB now..." Ugh. Annoying conflicts with the tcm_vhost -> vhost_scsi rename. Hopefully correctly resolved. * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (57 commits) caif_virtio: Remove bouncing email addresses lguest: improve code readability in lg_cpu_start. virtio-net: fill only rx queues which are being used lguest: map Switcher below fixmap. lguest: cache last cpu we ran on. lguest: map Switcher text whenever we allocate a new pagetable. lguest: don't share Switcher PTE pages between guests. lguest: expost switcher_pages array (as lg_switcher_pages). lguest: extract shadow PTE walking / allocating. lguest: make check_gpte et. al return bool. lguest: assume Switcher text is a single page. lguest: rename switcher_page to switcher_pages. lguest: remove RESERVE_MEM constant. lguest: check vaddr not pgd for Switcher protection. lguest: prepare to make SWITCHER_ADDR a variable. virtio: console: replace EMFILE with EBUSY for already-open port virtio-scsi: reset virtqueue affinity when doing cpu hotplug virtio-scsi: introduce multiqueue support virtio-scsi: push vq lock/unlock into virtscsi_vq_done virtio-scsi: pass struct virtio_scsi to virtqueue completion function ...

vhost_scsi: module rename
