From: Dinh Nguyen <[email protected]> The read_sched_clock should return the ~value because the clock is a countdown implementation. read_sched_clock() should be the same as __apbt_read_clocksource().
Signed-off-by: Dinh Nguyen <[email protected]> --- v5: Split up into 2 patches v4: Simplify the fix by simply returning ~__raw_readl(sched_io_base) v3: Use APBTMR_N_CURRENT_VALUE define in read_sched_clock() v2: Maintain backwards compatibility for "dw-apb-timer-sp" and "dw-apb-timer-osc". --- drivers/clocksource/dw_apb_timer_of.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clocksource/dw_apb_timer_of.c b/drivers/clocksource/dw_apb_timer_of.c index 45ba8ae..b29d7cd 100644 --- a/drivers/clocksource/dw_apb_timer_of.c +++ b/drivers/clocksource/dw_apb_timer_of.c @@ -108,7 +108,7 @@ static void __init add_clocksource(struct device_node *source_timer) static u64 read_sched_clock(void) { - return __raw_readl(sched_io_base); + return ~__raw_readl(sched_io_base); } static const struct of_device_id sptimer_ids[] __initconst = { -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
