Subject: [PATCH 0/2] vdpa: map shadow vrings with MAP_SHARED
Date: Fri, 2 Jun 2023 10:53:19 +0200 [thread overview]
Message-ID: <20230602085321.1814165-1-eperezma@redhat.com> (raw)
The vdpa devices that use va addresses neeeds these maps shared. Otherwise,
vhost_vdpa checks will refuse to accept the maps.
Discovered this issue while testing SVQ with vdpa sim, now defaulting to
use_va=on.
Eugenio Pérez (2):
vdpa: reorder vhost_vdpa_net_cvq_cmd_page_len function
vdpa: map shadow vrings with MAP_SHARED
