Cover letter [PATCH v9 00/13] Per sub-architecture SMP operations
As I promised at the ARM mini summit, I've updated Marc's series for smp operations according to my complaints. Unfortunately, I could not find version 7 of the patches when I started this, so I based my work on version 6 and had to redo the same changes.
The patches are also available on
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git testing/smp_ops
Arnd
Changelog:
Quoted 1 line
From v8:
- removed the string concatenating macros
- consolidated structures into a single smp_operations
- removed trivial instances of platform_cpu_kill and platform_cpu_disable, now handled by the default case
- split shmobile_cpu_kill into three separate functions, per soc
Quoted 1 line
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)
Quoted 1 line
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
Quoted 1 line
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
Quoted 1 line
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.
Quoted 1 line
From v3:
- Converted all SMP platforms
- Added some cleanup as a last patch
Quoted 1 line
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.
Quoted 1 line
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.
