Hi, We have two pathes to build stage2 mapping for MMIO regions.
Create time's path and stage2 fault path. Patch#1 removes the creation time's mapping of MMIO regions Patch#2 tries stage2 block mapping for host device MMIO at fault path Changelog: v4: - use get_vma_page_shift() handle all cases. (Marc) - get rid of force_pte for device mapping. (Marc) v3: - Do not need to check memslot boundary in device_rough_page_shift(). (Marc) Thanks, Keqian Keqian Zhu (2): kvm/arm64: Remove the creation time's mapping of MMIO regions kvm/arm64: Try stage2 block mapping for host device MMIO arch/arm64/kvm/mmu.c | 99 ++++++++++++++++++++++++-------------------- 1 file changed, 54 insertions(+), 45 deletions(-) -- 2.19.1
