The hierarchical timer pull model # # When timer wheel timers are armed they are placed into the timer # wheel of a CPU which is likely to be busy at the time of expiry. # This is done to avoid wakeups on potentially idle CPUs. # # This is wrong in several aspects: # # 1) The heuristics to select the target CPU are wrong by # definition as the chance to get the prediction right is # close to zero. # # 2) Due to #1 it is possible that timers are accumulated on # a single target CPU # # 3) The required computation in the enqueue path is just overhead # for dubious value especially under the consideration that the # vast majority of timer wheel timers are either canceled or # rearmed before they expire. # # The timer pull model avoids the above by removing the target # computation on enqueue and queueing timers always on the CPU on # which they get armed. # # This is achieved by having separate wheels for CPU pinned timers # and global timers which do not care about where they expire. # # As long as a CPU is busy it handles both the pinned and the global # timers which are queued on the CPU local timer wheels. # # When a CPU goes idle it evaluates its own timer wheels: # # - If the first expiring timer is a pinned timer, then the global # timers can be ignored as the CPU will wake up before they # expire. # # - If the first expiring timer is a global timer, then the expiry # time is propagated into the timer pull hierarchy and the CPU # makes sure to wake up for the first pinned timer. # # The timer pull hierarchy organizes CPUs in groups of eight at the # lowest level and at the next levels groups of eight groups up to # the point where no further aggregation of groups is required, i.e. # the number of levels is log8(NR_CPUS). The magic number of eight # has been established by experimention, but can be adjusted if # needed. # # In each group one busy CPU acts as the migrator. It's only one CPU # to avoid lock contention on remote timer wheels. # # The migrator CPU checks in its own timer wheel handling whether # there are other CPUs in the group which have gone idle and have # global timers to expire. If there are global timers to expire, the # migrator locks the remote CPU timer wheel and handles the expiry. # # Depending on the group level in the hierarchy this handling can # require to walk the hierarchy downwards to the CPU level. # # Special care is taken when the last CPU goes idle. At this point # the CPU is the systemwide migrator at the top of the hierarchy and # it therefore cannot delegate to the hierarchy. It needs to arm its # own timer device to expire either at the first expiring timer in # the hierarchy or at the first CPU local timer, which ever expires # first. # # This completely removes the overhead from the enqueue path, which # is e.g. for networking a true hotpath and trades it for a slightly # more complex idle path. # # This has been in development for a couple of years and the final # series has been extensively tested by various teams from silicon # vendors and ran through extensive CI. # # There have been slight performance improvements observed on network # centric workloads and an Intel team confirmed that this allows them # to power down a die completely on a mult-die socket for the first # time in a mostly idle scenario. # # There is only one outstanding ~1.5% regression on a specific # overloaded netperf test which is currently investigated, but the # rest is either positive or neutral performance wise and positive on # the power management side. # # - Fixes for the timekeeping interpolation code for cross-timestamps: # # cross-timestamps are used for PTP to get snapshots from hardware # timers and interpolated them back to clock MONOTONIC. The changes # address a few corner cases in the interpolation code which got the # math and logic wrong. # # - Simplifcation of the clocksource watchdog retry logic to # automatically adjust to handle larger systems correctly instead of # having more incomprehensible command line parameters. # # - Treewide consolidation of the VDSO data structures. # # - The usual small improvements and cleanups all over the place" # # * tag 'timers-core-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (62 commits) # timer/migration: Fix quick check reporting late expiry # tick/sched: Fix
