      [PATCH] i386 CPU hotplug · f3705136
      Zwane Mwaikambo 提交于
      (The i386 CPU hotplug patch provides infrastructure for some work which Pavel
      is doing as well as for ACPI S3 (suspend-to-RAM) work which Li Shaohua
      <shaohua.li@intel.com> is doing)
      
      The following provides i386 architecture support for safely unregistering and
      registering processors during runtime, updated for the current -mm tree.  In
      order to avoid dumping cpu hotplug code into kernel/irq/* i dropped the
      cpu_online check in do_IRQ() by modifying fixup_irqs().  The difference being
      that on cpu offline, fixup_irqs() is called before we clear the cpu from
      cpu_online_map and a long delay in order to ensure that we never have any
      queued external interrupts on the APICs.  There are additional changes to s390
      and ppc64 to account for this change.
      
      1) Add CONFIG_HOTPLUG_CPU
      2) disable local APIC timer on dead cpus.
      3) Disable preempt around irq balancing to prevent CPUs going down.
      4) Print irq stats for all possible cpus.
      5) Debugging check for interrupts on offline cpus.
      6) Hacky fixup_irqs() to redirect irqs when cpus go off/online.
      7) play_dead() for offline cpus to spin inside.
      8) Handle offline cpus set in flush_tlb_others().
      9) Grab lock earlier in smp_call_function() to prevent CPUs going down.
      10) Implement __cpu_disable() and __cpu_die().
      11) Enable local interrupts in cpu_enable() after fixup_irqs()
      12) Don't fiddle with NMI on dead cpu, but leave intact on other cpus.
      13) Program IRQ affinity whilst cpu is still in cpu_online_map on offline.

      [PATCH] ppc64: Add driver for BPA interrupt controllers · cebf589c
      Arnd Bergmann 提交于
      Add support for the integrated interrupt controller on BPA
      CPUs. There is one of those for each SMT thread.
      
      The mapping of interrupt numbers to HW interrupt sources
      is described in arch/ppc64/kernel/bpa_iic.h.
      
      This version hardcodes the 'Spider' chip as the secondary
      interrupt controller. That is not really generic for the
      architecture, but at the moment it is the only secondary
      PIC that exists.
      
      A little more work will be needed on this as soon as
      we have boards with multiple external interrupt controllers.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
