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 xen/arch/arm/mm.c | 12 ++++-------- xen/arch/arm/p2m.c | 30 ++++++++++++++++++++++-------- xen/include/asm-arm/p2m.h | 5 +++++ xen/include/asm-arm/page.h | 5 +++-- 4 files changed, 34 insertions(+), 18 deletions(-) -- 1.8.3.1
