Hi All, In remoteproc/remoteproc_virtio.c, accessing to resource table is not using io helpers, but resource table are normally mapped using ioremap or ioremap_wc. Should we switch to use ioread_x iowrite_x? In drivers/remoteproc/remoteproc_core.c, there are places to kmemdup resource table, should we use io helper? I asking because SCMI use io helper for shmem. For AMP, I think io helper should be used even we not meet issue now. Thanks, Peng.
