[PATCH v6 00/15] Per SoC descriptor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

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.

The last three patches consolidate some of the most commonly duplicated
hotplug code and move it to a common location.

Patches against v3.3-rc2. Tested on VExpress (A5 and A15), RealView EB-11MP,
OMAP4 (Panda) and Tegra2 (Harmony).

Changelog:

>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 (left overse 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.
