Subject: [PATCH V5 0/2] Virtio support for toolstack on Arm (Was "IOREQ feature (+ virtio-mmio) on Arm")
Date: Fri, 21 May 2021 16:16:43 +0300	[thread overview]
Message-ID: <1621603005-5799-1-git-send-email-olekstysh@gmail.com> (raw)

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

Hello all.

The purpose of this patch series is to add missing virtio-mmio bits to Xen toolstack on Arm.
The Virtio support for toolstack [1] was postponed as the main target was to upstream IOREQ/DM
support on Arm in the first place. Now, we already have IOREQ support in, so we can resume Virtio
enabling work. You can find previous discussion at [2].

Patch series [3] was reworked and rebased on recent "staging branch"
(972ba1d x86/shadow: streamline shadow_get_page_from_l1e()) and tested on
Renesas Salvator-X board + H3 ES3.0 SoC (Arm64) with "updated" virtio-mmio disk backend [4]
running in Driver domain and unmodified Linux Guest running on existing
virtio-blk driver (frontend). No issues were observed. Guest domain 'reboot/destroy'
use-cases work properly.

Any feedback/help would be highly appreciated.
