From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx> 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.
