Afzal Mohammed d08de0c19c [CPUFREQ] update lpj only if frequency has changed ... During scaling up of cpu frequency, loops_per_jiffy is updated upon invoking PRECHANGE notifier. If setting to new frequency fails in cpufreq driver, lpj is left at incorrect value. Hence update lpj only if cpu frequency is changed, i.e. upon invoking POSTCHANGE notifier. Penalty would be that during time period between changing cpu frequency & invocation of POSTCHANGE notifier, udelay(x) may not gurantee minimal delay of 'x' us for frequency scaling up operation. Perhaps a better solution would be to define CPUFREQ_ABORTCHANGE & handle accordingly, but then it would be more intrusive (using ABORTCHANGE may help drivers also; if any has registered notifier and expect POST for a PRECHANGE, their needs can be taken care using ABORT) Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Dave Jones <davej@redhat.com>		2012-01-06 10:10:53 -05:00
