From mboxrd@z Thu Jan 1 00:00:00 1970 From: marc.zyngier@arm.com (Marc Zyngier) Date: Tue, 12 Jun 2012 13:30:43 +0100 Subject: [PATCH v8 00/13] Per sub-architecture SMP operations Message-ID: <1339504256-11266-1-git-send-email-marc.zyngier@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch series is a small departure from the earlier series, which was trying to introduce a SoC descriptor. Instead, this one focusses on SMP operations, and only this, as per Arnd's request. Each platforms exports a "struct smp_ops" that is pointed to by their mach_desc. The last patch consolidates the definition of pen_release into the SMP code, though this is arguably wrong (most platforms shouldn't need the whole pen_release thing at all). Patches against v3.5-rc2. Tested on VExpress (Cortex A15). Also available at: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git smp_ops-v3.5-rc2 Changelog: >>From v7: - Dropped soc_desc, and focussed only on smp_ops - Fixed CONFIG_HOTPLUG_CPU typo (courtesy of Shawn Guo) - Marked {realview,vexpress}_cpu_die() as __cpuinit - Added support for spear13xx - Added pen_release consolidation (based on Arnd Bergman's patch) >>From v6: - Dropped the dummy_* stuff - Support for a number of new platforms - Added the soc_hotplug_ops() macro to hide some #ifdef-ery away - More exynos[ 45] churn - Fixed section mismatches >>From v5: - Added support for highbank and imx6q - Added support for new shmobile SMP platform - Add dummy_cpu_kill, dummy_cpu_disable and cpu_lowpower >>From v4: - Added an SMP registration interface and moved all SMP structures to smp.c. The end result is much cleaner. - Cleaned up patch 2 (leftovers from a previous rework) - NVIDIA/EXYNOS4 naming cleanup. >>From v3: - Converted all SMP platforms - Added some cleanup as a last patch >>From v2: - Split the SMP ops between init and runtime operations in order to have separate lifetimes for the different structures. This is not perfect though, as it still allows an __init function to make it to a runtime structure (all smp_*_ops structures are __initdata in order to be able to discard them). Thanks to Nico for pointing this out. - Use macros to hide the #ifdef-ery in the SoC descriptor init, courtesy of Arnd. >>From v1: - Move the SMP ops out of the descriptor, which makes the structure init a bit cleaner (thanks to Arnd). - Mark all structures __initdata and keep a copy of the used ones. - Keep a global pointer for the SMP ops.
