Since PXA27x requires at least +MIN_OSCR_DELTA, this causes us to flag an error. + +tick_program_event() then increments the next event time by +min_delta_ns. However, by the time we get back to programming +the next event, the OSCR has incremented such that we fail again. +We repeatedly retry, but the OSCR is too fast for us - we never +catch up, so we never break out of the loop - resulting in us +never apparantly resuming. + +Fix this by doubling min_delta_ns. + +Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> + +diff --git a/arch/arm/mach-pxa/time.c b/arch/arm/mach-pxa/time.c +index ac0bbad..7b7c017 100644 +--- a/arch/arm/mach-pxa/time.c ++++ b/arch/arm/mach-pxa/time.c +@@ -169,7 +169,7 @@ static void __init pxa_timer_init(void) + ckevt_pxa_osmr0.max_delta_ns = + clockevent_delta2ns(0x7fffffff, &ckevt_pxa_osmr0); + ckevt_pxa_osmr0.min_delta_ns = +- clockevent_delta2ns(MIN_OSCR_DELTA, &ckevt_pxa_osmr0) + 1; ++ clockevent_delta2ns(MIN_OSCR_DELTA * 2, &ckevt_pxa_osmr0) + 1; + + cksrc_pxa_oscr0.mult = + clocksource_hz2mult(clock_tick_rate, cksrc_pxa_oscr0.shift); + +------------------------------------------------------------------- +List admin: http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm-kernel +FAQ: http://www.arm.linux.org.uk/mailinglists/faq.php +Etiquette: http://www.arm.linux.org.uk/mailinglists/etiquette.php + |
