Subject: [PATCH v2 00/20] ARM: Add support for the Large Physical Address Extensions
Date: Fri, 12 Nov 2010 18:00:20 +0000 [thread overview]
Message-ID: <1289584840-18097-1-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:
- Upgraded to latest mainline kernel (2.6.37-rc1) solving several conflicts.
- Enable CONFIG_ARCH_DMA_ADDR_T_64BIT for future compatibility with the unified
dma_addr_t patch.
- PHYS_ADDR_FMT printk format changed to be ANSI C compliant.
- Alignment fault now uses SIGBUS instead of SIGILL.
- arch/arm/kernel/head.S modified to use SECTION_SHIFT and reduce the amount of
#ifdef's.
- setup_mm_for_reboot() modified for LPAE.
- identity_mapping_add/del() modified for LPAE.
- Removed FIRST_USER_PGD_NR definition as the place where it was used have been
modified.
Any comments are welcome. Thanks.
