[PATCH 00/51] rtc: stop using rtc deprecated functions

by Benjamin Gaignard

rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they rely on 32bits variables and that will make rtc break in y2038/2016. The goal of this series of patches is ti stop using those two functions and use instead to safer 64bits ones. It also remove change .set_mmss to set_mmss64 callback for the same reasons. Those 51 patches almost clean all the drivers except the few that I haven't been able to compile because of cross-toolchains issues (au1xxx, mpc5121, ps3, puv3, sun4v, tx4939, starfire, ls1x ...) Obviously I don't have all those hardwares in my hands so I have only check that the patches compile without warnings but it up to each maintainer to valid them on real hardware.

[PATCH] cpufreq: Find transition latency dynamically

by Viresh Kumar

The transition_latency_ns represents the maximum time it can take for the hardware to switch from/to any frequency for a CPU. The transition_latency_ns is used currently for two purposes: o To check if the hardware latency is over the maximum allowed for a governor (only for ondemand and conservative (why not schedutil?)) and to decide if the governor can be used or not. o To calculate the sampling_rate or rate_limit for the governors by multiplying transition_latency_ns with a constant. The platform drivers can also set this value to CPUFREQ_ETERNAL if they don't know this number and in that case we disallow use of ondemand and conservative governors as the latency would be higher than the maximum allowed for the governors. In many cases this number is forged by the driver authors to get the default sampling rate to a desired value. Anyway, the actual latency values can differ from what is received from the hardware designers. Over that, what is provided by the drivers is most likely the time it takes to change frequency of the hardware, which doesn't account the software overhead involved. In order to have guarantees about this number, this patch tries to calculate the latency dynamically at cpufreq driver registration time by first switching to min frequency, then to the max and finally back to the initial frequency. And the maximum of all three is used as the target_latency. Specifically the time it takes to go from min to max frequency (when the software runs the slowest) should be good enough, and even if there is a delta involved then it shouldn't be a lot. For now this patch limits this feature only for platforms which have set the transition latency to CPUFREQ_ETERNAL. Maybe we can convert everyone to use it in future, but lets see. This is tested over ARM64 Hikey platform which currently sets "clock-latency" as 500 us from DT, while with this patch the actualy value increased to 800 us.
