Subject: [PATCH v4 00/19] ARM: Add support for the Large Physical Address Extensions
Date: Mon, 24 Jan 2011 17:55:42 +0000 [thread overview]
Message-ID: <1295891761-18366-1-git-send-email-catalin.marinas@arm.com> (raw)
Hi,
This set of patches adds support for the Large Physical Extensions on
the ARM architecture (available with the Cortex-A15 processor). LPAE
comes with a 3-level page table format (compared to 2-level for the
classic one), allowing up to 40-bit physical address space.
The ARM LPAE documentation is available from (free registration needed):
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406b_virtualization_extns/index.html
The full set of patches (kernel fixes, LPAE and support for an emulated
Versatile Express with Cortex-A15 tile) is available on this branch:
git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-2.6-cm.git arm-lpae
Changelog:
- Rebased on 2.6.38-rc1. This kernel includes Russell's refactoring of
the page table maintenance.
- PTE_PFN_MASK renamed to PHYS_MASK and some of the functions using this
macro have been unified between classic and LPAE page table format.
- Fixes for modules/pkmap page table entries - the corresponding PMD is
preallocated in pgd_alloc() and cleaned-up in pgd_free().
- Identity mapping support following mainline changes.
Catalin Marinas (14):
ARM: Make the argument to virt_to_phys() "const volatile"
ARM: LPAE: Fix early_pte_alloc() assumption about the Linux PTE
ARM: LPAE: Use PMD_(SHIFT|SIZE|MASK) instead of PGDIR_*
ARM: LPAE: Factor out 2-level page table definitions into separate
files
ARM: LPAE: Add (pte|pmd|pgd|pgprot)val_t type definitions as u32
ARM: LPAE: Use a mask for physical addresses in page table entries
ARM: LPAE: Introduce the 3-level page table format definitions
ARM: LPAE: Page table maintenance for the 3-level format
ARM: LPAE: MMU setup for the 3-level page table format
ARM: LPAE: Add fault handling support
ARM: LPAE: Add context switching support
ARM: LPAE: Add identity mapping support for the 3-level page table
format
ARM: LPAE: Add SMP support for the 3-level page table format
ARM: LPAE: Add the Kconfig entries
Will Deacon (5):
ARM: LPAE: use long long format when printing physical addresses and
ptes
ARM: LPAE: use phys_addr_t instead of unsigned long for physical
addresses
ARM: LPAE: Use generic dma_addr_t type definition
ARM: LPAE: mark memory banks with start > ULONG_MAX as highmem
ARM: LPAE: add support for ATAG_MEM64
