From: Oleksandr Tyshchenko <oleksandr_tyshche...@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 discussions at [2]. Patch series [3] is based on recent "staging" branch (fa6dc0879ffd3dffffaea2837953c7a8761a9ba0 page_alloc: assert IRQs are enabled in heap alloc/free) and tested on Renesas Salvator-X board + H3 ES3.0 SoC (Arm64) with virtio-mmio based virtio-disk backend [4] running in Dom0 (or 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.
