Subject: [PATCH 0/8] Support 4 levels of translation tables for ARM64
Date: Mon, 14 Apr 2014 16:39:51 +0900 [thread overview]
Message-ID: <000001cf57b4$b86facd0$294f0670$@samsung.com> (raw)
Hi All,
This patchset supports 4 levels of tranlsation tables for ARM64.
Firstly, the patchset decouples page size from level of translation tables
as taking account into the comment from Catalin Marinas:
http://www.spinics.net/linux/lists/arm-kernel/msg319552.html
Then, it implements 4 levels of translation tables for both native, HYP
and stage2 sides.
This series is validated with Fast Models and kvmtool as platform and guest
launcher, respectively.
Jungseok Lee (8):
arm64: Use pr_* instead of printk
arm/arm64: KVM: Fix line length exceeding 80 characters
arm64: Decouple page size from level of translation tables
arm64: Introduce a kernel configuration option for VA_BITS
arm64: Add a description on 48-bit address space with 4KB pages
arm64: Add 4 levels of page tables definition with 4KB pages
arm64: mm: Implement 4 levels of translation tables
arm64: KVM: Implement 4 levels of translation tables for HYP and stage2
