agtimer(4/arm64): call CPU_BUSY_CYCLE() during spin-loop For consistency with other delay(9) implementations, agtimer(4/arm64) ought to call CPU_BUSY_CYCLE() as it spins. kettenis@ notes that we could reduce the power consumed in agtimer_delay() by enabling CNTKCTL_EL1.EVNTEN and configuring ENTKCTL_EL1.EVNTI. kettenis@ also notes that Armv8.7 adds FEAT_WFxT, which will, when the feature appears in real hardware, make it even easier to save power in agtimer_delay(). With input from drahn@ and kettenis@. Thread: https://marc.info/?l=openbsd-tech&m=169146193022516&w=2 ok kettenis@ |

Move the single_thread_check() to the start of userret(). This way threads stopped by SINGLE_SUSPEND will check for pending signals right after being released instead of returning to userland first. The same order of check is already used in sleep_signal_check(). OK mpi@ |

hardclock(9), roundrobin: make roundrobin() an independent clock interrupt - Remove the roundrobin() call from hardclock(9). - Revise roundrobin() to make it a valid clock interrupt callback. It is still periodic and it still runs at one tenth of the hardclock frequency. - Account for multiple expirations in roundrobin(): if two or more roundrobin periods have elapsed, set SPCF_SHOULDYIELD on the running thread immediately to simulate normal behavior. - Each schedstate_percpu has its own roundrobin() handle, spc_roundrobin. spc_roundrobin is started/advanced during clockintr_cpu_init(). Intervals elapsed across suspend/resume are discarded. - rrticks_init and schedstate_percpu.spc_rrticks are now useless: delete them. Tweaked by mpi@. With input from mpi@ and claudio@.
