Subject: [PATCH v4 0/2] kvm/arm64: Try stage2 block mapping for host device MMIO
Date: Thu, 15 Apr 2021 22:03:26 +0800 [thread overview]
Message-ID: <20210415140328.24200-1-zhukeqian1@huawei.com> (raw)
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
