This patchset adds support for 64 bit counters in the generic
sched_clock code and converts drivers over to use it. Based
on v3.11-rc1.
Changes since v3:
* Move to use seqcount to fix issues with 64-bit cyc counters
* Move to hrtimer to fix underflow/overflow errors in wraparound
calculation
* Use of 1 hour in clocks_calc_mult_shift
* Converted over drivers in drivers/clocksource
Stephen Boyd (17):
clocksource: Extract max nsec calculation into separate function
sched_clock: Use seqcount instead of rolling our own
sched_clock: Use an hrtimer instead of timer
sched_clock: Add support for >32 bit sched_clock
arch_timer: Move to generic sched_clock framework
sched_clock: Remove sched_clock_func() hook
clocksource: bcm2835: Switch to sched_clock_register()
ocksource: dbx500-prcmu: Switch to sched_clock_register()
clocksource: dw_apb_timer_of: Switch to sched_clock_register()
clocksource: mxs_timer: Switch to sched_clock_register()
clocksource: nomadik: Switch to sched_clock_register()
clocksource: samsung_pwm_timer: Switch to sched_clock_register()
clocksource: tegra: Switch to sched_clock_register()
clocksource: time-armada-370-xp: Switch to sched_clock_register()
clocksource: sirf: Switch to sched_clock_register() and use 64 bits
clocksource: vf_pit_timer: Switch to sched_clock_register()
sched_clock: Deprecate setup_sched_clock()
Ok, so if there's no major objections with this set, here's my plan:
1) I'm going to queue 1-4 in a fortglx/3.12/sched-clock64 branch, I'll
send git pull requests to both Thomas and Olof, so they can both merge
the common base for the conversion code in both drivers/clocksource and
arch/arm.
2) If I can get Catalin's ack on 5/17, I'll queue it and 6/17 for
tip/timers/core.
3) I'll also queue the rest and send to Thomas or Daniel for
tip/timers/core.
That sound ok to everyone?
thanks
