      x86: consolidate header guards · 77ef50a5
      Vegard Nossum 提交于
      This patch is the result of an automatic script that consolidates the
      format of all the headers in include/asm-x86/.
      
      The format:
      
      1. No leading underscore. Names with leading underscores are reserved.
      2. Pathname components are separated by two underscores. So we can
         distinguish between mm_types.h and mm/types.h.
      3. Everything except letters and numbers are turned into single
         underscores.

      x86: expand /proc/interrupts to include missing vectors, v2 · 38e760a1
      Joe Korty 提交于
      Add missing IRQs and IRQ descriptions to /proc/interrupts.
      
      /proc/interrupts is most useful when it displays every IRQ vector in use by
      the system, not just those somebody thought would be interesting.
      
      This patch inserts the following vector displays to the i386 and x86_64
      platforms, as appropriate:
      
      	rescheduling interrupts
      	TLB flush interrupts
      	function call interrupts
      	thermal event interrupts
      	threshold interrupts
      	spurious interrupts
      
      A threshold interrupt occurs when ECC memory correction is occuring at too
      high a frequency.  Thresholds are used by the ECC hardware as occasional
      ECC failures are part of normal operation, but long sequences of ECC
      failures usually indicate a memory chip that is about to fail.
      
      Thermal event interrupts occur when a temperature threshold has been
      exceeded for some CPU chip.  IIRC, a thermal interrupt is also generated
      when the temperature drops back to a normal level.
      
      A spurious interrupt is an interrupt that was raised then lowered by the
      device before it could be fully processed by the APIC.  Hence the apic sees
      the interrupt but does not know what device it came from.  For this case
      the APIC hardware will assume a vector of 0xff.
      
      Rescheduling, call, and TLB flush interrupts are sent from one CPU to
      another per the needs of the OS.  Typically, their statistics would be used
      to discover if an interrupt flood of the given type has been occuring.
      
      AK: merged v2 and v4 which had some more tweaks
      AK: replace Local interrupts with Local timer interrupts
      AK: Fixed description of interrupt types.

      x86: remove reminder of i386 irqstat per cpu conversion · 6d43be8e
      Thomas Gleixner 提交于
      The i386 irqstat per cpu conversion left an bogus export of the old
      irqstat array in the header file. Remove it.

      x86: Fix irq0 / local apic timer accounting · 3c9aea47
      Thomas Gleixner 提交于
      The clock events merge introduced a change to the nmi watchdog code to
      handle the not longer increasing local apic timer count in the
      broadcast mode. This is fine for UP, but on SMP it pampers over a
      stuck CPU which is not handling the broadcast interrupt due to the
      unconditional sum up of local apic timer count and irq0 count.
      
      To cover all cases we need to keep track on which CPU irq0 is
      handled. In theory this is CPU#0 due to the explicit disabling of irq
      balancing for irq0, but there are systems which ignore this on the
      hardware level. The per cpu irq0 accounting allows us to remove the
      irq0 to CPU0 binding as well.
      
      Add a per cpu counter for irq0 and evaluate this instead of the global
      irq0 count in the nmi watchdog code.

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      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!
