[PATCH v2 0/7] Support 4 levels of translation tables for ARM64
Hi All, This the 2nd 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 native, HYP and stage2 sides. All ARMv8 and ARMv7 related changes are validated with FastModels+kvmtool and A15+QEMU, respectively. Changes since v1: - fixed unmatched data types as per Steve's comment - removed unnecessary #ifdef in arch/arm64/mm/* as per Steve's comment - revised create_pgd_entry to deal with PUD entry as per Steve's comment - introduced a macro for initial memblock limit as per Steve's comment - dropped "Fix line length exceeding 80 characters" patch as per Marc's comment - removed unnecessary #ifdef in arch/arm/kvm/mmu.c as per Marc's comment - added a macro for a number of objects of as per Marc's comment Jungseok Lee (7): arm64: Use pr_* instead of printk 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 Documentation/arm64/memory.txt| 59 +-- arch/arm/include/asm/kvm_mmu.h| 10 ++ arch/arm/kvm/mmu.c| 88 ++--- arch/arm64/Kconfig| 51 +- arch/arm64/include/asm/kvm_arm.h | 20 arch/arm64/include/asm/kvm_mmu.h | 10 ++ arch/arm64/include/asm/memblock.h |6 ++ arch/arm64/include/asm/memory.h |6 +- arch/arm64/include/asm/page.h |6 +- arch/arm64/include/asm/pgalloc.h | 24 - arch/arm64/include/asm/pgtable-4level-hwdef.h | 50 ++ arch/arm64/include/asm/pgtable-4level-types.h | 71 + arch/arm64/include/asm/pgtable-hwdef.h|8 +- arch/arm64/include/asm/pgtable.h | 52 -- arch/arm64/include/asm/tlb.h | 10 +- arch/arm64/kernel/head.S | 40 +--- arch/arm64/kernel/traps.c | 19 ++-- arch/arm64/mm/fault.c |1 + arch/arm64/mm/mmu.c | 16 ++- 19 files changed, 485 insertions(+), 62 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
