  • 2f0778afa   ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime ... Browse Code »
    86

    sched_clock() is yet another blocker on the road to the single
    image. This patch implements an idea by Russell King:

    http://www.spinics.net/lists/linux-omap/msg49561.html

    Instead of asking the platform to implement both sched_clock()
    itself and the rollover callback, simply register a read()
    function, and let the ARM code care about sched_clock() itself,
    the conversion to ns and the rollover. sched_clock() uses
    this read() function as an indirection to the platform code.
    If the platform doesn't provide a read(), the code falls back
    to the jiffy counter (just like the default sched_clock).

    This allow some simplifications and possibly some footprint gain
    when multiple platforms are compiled in. Among the drawbacks,
    the removal of the *_fixed_sched_clock optimization which could
    negatively impact some platforms (sa1100, tegra, versatile
    and omap).

    Tested on 11MPCore, OMAP4 and Tegra.

    Move the xtime write mode seqlock into timer_tick(), so it only
    surrounds the call to do_timer().

    This avoids a deadlock in update_process_times() ...
    hrtimer_get_softirq_time() which tries to get a read mode seqlock
    on xtime, thereby preventing booting.

  • fcae8e098   [ARM] sa1100: remove boot time RTC initialisation ... Browse Code »

    The RTC library code contains everything necessary to set the
    system time from the RTC; for similar reasons as the previous
    commit, it's far better to let the RTC library code sort this
    out rather than implement something which might not be
    appropriate for everyone.

    Don't reset OSCR to zero as this prevents us from having a contiguous
    time source. The value returned by sched_clock() is reset to zero in the
    middle of the boot process otherwise, making CONFIG_PRINTK_TIME rather
    messed up.

    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!
