Now that many more architectures build vhost, a couple of these (um, and arm with deprecated oabi) have reported build failures with randconfig, however fixes for that need a bit more discussion/testing and will be merged separately. Not a regression - these previously simply didn't have vhost at all. Also, there's some DMA API code in the vdpa simulator is hacky - if no solution surfaces

First it asks for vDPA driver for virtio devices (VIRTIO_VDPA) support. If you say 'n', it then asks *again* for VDPA drivers (VDPA_MENU). And then when you say 'n' to *that* it asks you for Vhost driver for vDPA-based backend (VHOST_VDPA). This kind of crazy needs to stop. Doing kernel configuration is not supposed to be like some truly horrendously boring Colossal Cave Adventure game where you have to search for a way o...

Hi all: This is an update version of vDPA support in kernel. vDPA device is a device that uses a datapath which complies with the virtio specifications with vendor specific control path. vDPA devices can be both physically located on the hardware or emulated by software. vDPA hardware devices are usually implemented through PCIE with the following types: - PF (Physical Function) - A single

Hi all: This is an updated version of kernel support for vDPA device. Various changes were made based on the feedback since last verion. One major change is to drop the sysfs API and leave the management interface for future development, and introudce the incremental DMA bus operations. Please see changelog for more information. The work on vhost, IFCVF (intel VF driver for vDPA) and qemu is
