      [PATCH] ARM: Generic Dynamic Tick Timer support for ARM, take 4 · 8749af68
      Russell King 提交于
      This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is
      also known as VST (Variable Scheduling Timeouts).
      
      Dynamic Tick has been in use in the OMAP tree since last October.  The
      patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ
      is defined.  This patch has the following fixed based on comments from
      RMK:
      - Time is updated before calling interrupt handlers.
      - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts
      - Moved struct dyn_tick_timer to time.h until we at some point probably
        have an arch independent dyn-tick.h
      - Cleaned up testing for DYN_TICK_ENABLED in irq.c
      
       I've cleaned up this patch to fix some remaining issues:
       - Call the timer tick handler with irqs disabled, as it would be from
         a normal interrupt
       - if we have a dyn_tick, we better implement all methods.
       - generic timer_dyn_reprogram() call, to be called before sleeping
       - added command line option - "dyntick=" to allow boot-time control
         of this feature

      [PATCH] ARM: 2752/1: disable ixp2000 PCI I/O software workaround on chips that don't need it · 321ab6a5
      Lennert Buytenhek 提交于
      Patch from Lennert Buytenhek
      
      The later ixp2000 models don't need the PCI I/O workaround that we
      currently perform.  Add a config option to disable the workaround,
      and panic on boot if a kernel without the workaround is booted on a
      buggy chip.  As only pre-production ixp2000s need the workaround,
      the default is for it not to be configured in.
