Message-Id: <1347035226-18649-1-git-send-email-catalin.marinas@arm.com> Date: Fri, 7 Sep 2012 17:26:35 +0100 From: Catalin Marinas <catalin.marinas@....com> To: linux-arch@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, Arnd Bergmann <arnd@...db.de> Subject: [PATCH v3 00/31] AArch64 Linux kernel port This is the 3rd version of patches implementing Linux kernel support for the 64-bit ARM architecture. Most of the review comments for the previous release have been implemented. There are a few left (like generic timer dts specification) but the main goal was to freeze the user ABI. The Linux kernel patches are available on this tree: git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64.git upstream Main changes since the previous version: - ptrace interface now using regsets for TLS and hardware debug registers. - sys_personality fixes. PER_LINUX is the default for all tasks (32 or 64-bit) and there is no compat_sys_personality defined. - Kconfig clean-up (unused symbols, AARCH32_EMULATION removed in favour of COMPAT). - Clean-up of the __cpuc_* function prefixes. - CPU information table implemented in C rather than assembly. - __bad_* function calls replaced with BUILD_BUG. - Inline get_user/put_user (code cleaner, slightly bigger kernel Image). - DMA API implementation simplified, defaulting to swiotlb. It will be extended as hardware becomes available. - Arch-specific code in the generic timer patch moved to arch/arm64/. - Comment fixes and clarifications. Background to the 64-bit ARM architecture: ARM introduced AArch64 as part of the ARMv8 architecture and consists of a substantially revised exception model (with 4 exception levels: EL0 - user, EL1 - kernel, EL2 - hypervisor, EL3 - secure monitor), new A64 instruction set based on larger register file, new FP/SIMD instructions. The new ABI is LP64 and takes advantage of the larger register file. It also mandates FP. AArch64 documentation currently available (publicly, though click-through agreement required): - Instruction Set Overview: http://infocenter.arm.com/help/topic/com.arm.doc.genc010197a/index.html - ABI
