  • e9e2cdb41   [PATCH] clockevents: i386 drivers ... Browse Code »

    Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update
    the timer IRQ to call into the PIT/HPET driver's event handler and the
    lapic-timer IRQ to call into the lapic clockevent driver. The assignement of
    timer functionality is delegated to the core framework code and replaces the
    compile and runtime evalution in do_timer_interrupt_hook()

    Use the clockevents broadcast support and implement the lapic_broadcast
    function for ACPI.

    No changes to existing functionality.

    Clean up and refactor i386 sub-architecture setup.

    This change moves all the code from the
    asm-i386/mach-*/setup_arch_pre/post.h headers, into
    arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to
    setup_arch.h, and contains only things which should be in header files. It
    is purely code-motion; there should be no functional changes at all.

    Several functions in arch/i386/kernel/setup.c needed to be made non-static
    so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is
    used to hold the prototypes for these functions.

  • 9c869edac   [PATCH] Fix topology.c location ... Browse Code »

    When compiling a non-default subarch, topology.c is missing from the kernel
    build. This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition,
    on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to
    reference uninitialized data that should have been set up by the initcall
    in topology.c which calls register_cpu. This causes a kernel panic on boot
    on newer Intel processors. Moving topology.c to arch/i386/kernel fixes
    both of these problems.

    Thanks to Dan Hecht for finding and fixing this problem.

  • ce3a161e6   [PATCH] useless includes of linux/irq.h in arch/i386 ... Browse Code »

    Most of these guys are simply not needed (pulled by other stuff
    via asm-i386/hardirq.h). One that is not entirely useless is hilarious -
    arch/i386/oprofile/nmi_timer_int.c includes linux/irq.h... as a way to
    get linux/errno.h

  • 76e4f660d   [PATCH] x86_64: CPU hotplug support ... Browse Code »

    Experimental CPU hotplug patch for x86_64
    -----------------------------------------
    This supports logical CPU online and offline.
    - Test with maxcpus=1, and then kick other cpu's off to test if init code
    is all cleaned up. CONFIG_SCHED_SMT works as well.
    - idle threads are forked on demand from keventd threads for clean startup

    TBD:
    1. Not tested on a real NUMA machine (tested with numa=fake=2)
    2. Handle ACPI pieces for physical hotplug support.

  • 67664c8f7   [PATCH] i386: Dont use IPI broadcast when using cpu hotplug. ... Browse Code »

    This patch introduces a startup parameter no_broadcast. When we enable
    CONFIG_HOTPLUG_CPU, we dont want to use broadcast shortcut as it has ill
    effects on a offline cpu. If we issue broadcast, the IPI is also delivered
    to offline cpus, or partially up cpu causing stale IPI's to be handled,
    which is a problem and can cause undesirable effects.

    Introduces a new startup cmdline option no_ipi_broadcast, that can be
    switched at cmdline if necessary.

    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!
