This allows us to utilize the more efficient architected timer on certain ARM SoCs for normal operation instead of permanentely using the slow to access SoC specific clockevent device. - Print the name of the broadcast/wakeup device in /proc/timer_list - Make the clocksource watchdog more robust against delays between reading the current active clocksource and the watchdog clocksource. Such delays can be caused by NMIs, SMIs and vCPU preemption. Handle this by reading the watchdog clocksource twice, i.e. before and after reading the current active clocksource. In case that the two watchdog reads shows an excessive time delta, the read sequence is repeated up to 3 times. - Improve the debug output and add a test module for the watchdog mechanism. - Reimplementation of the venerable time64_to_tm() function with a faster and significantly smaller version. Straight from the source, i.e. the author of the related research paper contributed this! Driver changes: - No new drivers, not even new device tree bindings! - Fixes, improvements and cleanups and all over the place" * tag 'timers-core-2021-06-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) time/kunit: Add missing MODULE_LICENSE() time: Improve performance of time64_to_tm() clockevents: Use list_move() instead of list_del()/list_add() clocksource: Print deviation in nanoseconds when a clocksource becomes unstable clocksource: Provide kernel module to test clocksource watchdog clocksource: Reduce clocksource-skew threshold clocksource: Limit number of CPUs checked for clock synchronization clocksource: Check per-CPU clock synchronization when marked unstable clocksource: Retry clock read if long delays detected clockevents: Add missing parameter documentation clocksource/drivers/timer-ti-dm: Drop unnecessary restore clocksource/arm_arch_timer: Improve Allwinner A64 timer workaround clocksource/drivers/arm_global_timer: Remove duplicated argument in arm_global_timer clocksource/drivers/arm_global_timer: Make symbol 'gt_clk_rate_change_nb' static arm: zynq: don't disable CONFIG_ARM_GLOBAL_TIMER due to CONFIG_CPU_FREQ anymore clocksource/drivers/arm_global_timer: Implement rate compensation whenever source clock changes clocksource/drivers/ingenic: Rename unreasonable array names clocksource/drivers/timer-ti-dm: Save and restore timer TIOCP_CFG clocksource/drivers/mediatek: Ack and disable interrupts on suspend clocksource/drivers/samsung_pwm: Constify source IO memory ... |
