Subject: [RFC/PATCH 0/1] virtio_mmio: hypervisor specific interfaces for MMIO
Date: Thu, 30 Apr 2020 15:32:55 +0530	[thread overview]
Message-ID: <1588240976-10213-1-git-send-email-vatsa@codeaurora.org> (raw)

The Type-1 hypervisor we are dealing with does not allow for MMIO transport. 
[1] summarizes some of the problems we have in making virtio work on such
hypervisors. This patch proposes a solution for transport problem viz how we can
do config space IO on such a hypervisor. Hypervisor specific methods
introduced allows for seamless IO of config space.

This patch is meant to seek comments. If its considered to be in right
direction, will work on making it more complete and send the next version!
