As a consequence applications which aligned their periodic # execution so that it does not collide with the tick were not longer # guaranteed that the tick period starts from time 0. # # The fix for this regression was to realign the tick when it is # initially set up to a multiple of tick periods. That works as long as # the underlying tick device supports periodic mode, but breaks under # certain conditions when the tick device supports only one shot mode. # # Depending on the offset, the alignment delta to clock MONOTONIC can # get in a range where the minimal programming delta of the underlying # clock event device is larger than the calculated delta to the next # tick. This results in a boot hang as the tick code tries to play catch # up, but as the tick never fires jiffies are not advanced so it keeps # trying for ever. # # Solve this by moving the tick alignement into the NOHZ / HIGHRES # enablement code because at that point it is guaranteed that the # underlying clocksource is high resolution capable and not longer # depending on the tick. # # This is far before user space starts, so at the point where # applications try to align their timers, the old behaviour of the tick # happening at a multiple of nanoseconds per tick starting from clock # MONOTONIC = 0 is restored" # # * tag 'timers-urgent-2023-06-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: # tick/common: Align tick period during sched_timer setup # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 dad9774deaf1cf8e8f7483310dfb2690310193d2 # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- 64r6el_defconfig Using /kisskb/src/arch/mips/configs/generic_defconfig as base Merging /kisskb/src/arch/mips/configs/generic/64r6.config Merging /kisskb/src/arch/mips/configs/generic/el.config Merging /kisskb/src/arch/mips/configs/generic/board-boston.config Merging /kisskb/src/arch/mips/configs/generic/board-marduk.config Merging /kisskb/src/arch/mips/configs/generic/board-ranchu.config Merging /kisskb/src/arch/mips/configs/generic/board-virt.config # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r6el_defconfig_mips-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/mips-linux/bin/mips-linux- Completed OK # rm -rf /kisskb/build/linus_64r6el_defconfig_mips-gcc12 # Build took: 0:01:35.815843
