Re: [PATCH v7 0/2] xen/riscv: introduce identity mapping



Hi,

The patch series introduces things necessary to implement identity mapping:
   1. Make identity mapping for the entire Xen.
   2. Enable MMU.
   3. Jump to the virtual address world
   4. Remove identity mapping.

Also current patch series introduces the calculation of physical offset before
MMU is enabled as access to physical offset will be calculated wrong after
MMU will be enabled because access to phys_off variable is PC-relative and
in the case when linker address != load address, it will cause MMU fault.

The reason for this patch series can be found here:
https://lore.kernel.org/xen-devel/4e336121-fc0c-b007-bf7b-430352563d55@xxxxxxxxxx/

During the last community call it was pointed out that this is missing a formal ack. Now that we have no RISC-V maintainers, this would fall to the REST.

@Jan, you reviewed the previous version of the series. Would you be able to provide a formal ack?

Cheers,
