  • a241ec65a   [PATCH] RCU torture-testing kernel module ... Browse Code »

    This patch is a rewrite of the one submitted on October 1st, using modules
    (http://marc.theaimsgroup.com/?l=linux-kernel&m=112819093522998&w=2).

    This rewrite adds a tristate CONFIG_RCU_TORTURE_TEST, which enables an
    intense torture test of the RCU infratructure. This is needed due to the
    continued changes to the RCU infrastructure to accommodate dynamic ticks,
    CPU hotplug, realtime, and so on. Most of the code is in a separate file
    that is compiled only if the CONFIG variable is set. Documentation on how
    to run the test and interpret the output is also included.

    This code has been tested on i386 and ppc64, and an earlier version of the
    code has received extensive testing on a number of architectures as part of
    the PREEMPT_RT patchset.

  • 0d078f6f9   [PATCH] CONFIG_IA32 ... Browse Code »

    Add CONFIG_X86_32 for i386. This allows selecting options that only apply
    to 32-bit systems.

    (X86 && !X86_64) becomes X86_32
    (X86 || X86_64) becomes X86

  • 8446f1d39   [PATCH] detect soft lockups ... Browse Code »

    This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP.

    When enabled then per-CPU watchdog threads are started, which try to run
    once per second. If they get delayed for more than 10 seconds then a
    callback from the timer interrupt detects this condition and prints out a
    warning message and a stack dump (once per lockup incident). The feature
    is otherwise non-intrusive, it doesnt try to unlock the box in any way, it
    only gets the debug info out, automatically, and on all CPUs affected by
    the lockup.

  • 37fce857b   [PATCH] uml: split CONFIG_FRAME_POINTER from DEBUG_INFO ... Browse Code »

    Until now, FRAME_POINTER was set = DEBUG_INFO for UML. Change it to be the
    default way, so that it can be enabled alone (for instance to get better
    backtraces on crashes). The call-trace dumper which uses the frame pointer is
    not yet in, I'm going to introduce it in a separate patch.

    This patch eliminates all kernel BUGs, trims about 35k off the typical
    kernel, and makes the system slightly faster.

    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!
