[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! 1. https://lkml.org/lkml/2020/4/28/427 Srivatsa Vaddagiri (1): virtio: Introduce MMIO ops drivers/virtio/virtio_mmio.c | 131 ++++++++++++++++++++++++++----------------- include/linux/virtio.h | 14 +++++ 2 files changed, 94 insertions(+), 51 deletions(-) -- 2.7.4 -- QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
