• 6e84200c0   virtio-pmem: Add virtio pmem driver ... Browse Code »

  This patch adds virtio-pmem driver for KVM guest.

  Guest reads the persistent memory range information from
  Qemu over VIRTIO and registers it on nvdimm_bus. It also
  creates a nd_region object with the persistent memory
  range information so that existing 'nvdimm/pmem' driver
  can reserve this into system memory map. This way
  'virtio-pmem' driver uses existing functionality of pmem
  driver to register persistent memory compatible for DAX
  capable filesystems.

  This also provides function to perform guest flush over
  VIRTIO from 'pmem' driver when userspace performs flush
  on DAX memory range.
