[Xen-devel] [PATCH 0/3] ARM: Support read-only mapping in the grant table

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi,

This small patch series implements read-only mapping for the grant table.

The read-only mapping is used by block-front when persistent grants is not used.
It's the case when a freebsd domU is booting on Xen on ARM.

The first two patches extend the p2m interface to support read-only mapping.
The third patch add support to read-only mapping in the grant table.

Cheers,

Julien Grall (3):
  xen/arm: p2m: extend create_p2m_entries to support read-only mapping
  xen/arm: p2m: add guest_physmap_add_page_rw
  xen/arm: grant-table: Support read-only mapping
