From mboxrd@z Thu Jan 1 00:00:00 1970 From: marc.zyngier@arm.com (Marc Zyngier) Date: Thu, 7 Jun 2012 17:09:17 +0100 Subject: [PATCH v7 00/12] Per SoC descriptor Message-ID: <1339085369-26073-1-git-send-email-marc.zyngier@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org [As per Arnd request, I've updated this patch series, in the hope that it could be useful to the single zImage work] This patch series introduces a per-soc descriptor which should, in the end, contain most of the SoC specific operations. This first patch series introduces the arm_soc_desc structure, adds per-soc SMP and CPU hotplug operations, and converts all SMP platform to this new scheme. Patches against v3.5-rc1. Tested on VExpress (Cortex A15). Also available at: git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git soc_desc-v3.5-rc1 Changelog: >>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.
