Subject: [PATCH 00 of 11] (v3) arm: SMP boot
Date: Fri, 9 Mar 2012 16:47:39 +0000 [thread overview]
Message-ID: <patchbomb.1331311659@whitby.uk.xensource.com> (raw)
This patch series implements SMP boot for arch/arm, as far as getting
all CPUs up and running the idle loop.
Changes from v2:
- Fixed a bug in context switching in the percpu patch
- Added two new patches, not strictly for SMP boot, but
related, and apply after this series:
- Poison, unmap and free the __init* areas after boot.
- Use 'WFI' to take the CPu to a low power state in the idle loop.
Changes from v1:
- moved barriers out of loop in udelay()
- dropped broken GIC change in favour of explanatory comment
- made the increment of ready_cpus atomic (I couldn't move the
increment to before signalling the next CPU because the PT
switch has to happen between them)
- Made secondary CPUs come up directly on the idle vcpus' stacks,
avoiding the whole business of allocating and tracking boot stacks.
- Added a new patch to do late-boot MMU fixups on secondary CPUs.
Cheers,
Tim.
