Use the new __nullable CFI # stub tags instead. # # - On Sapphire Rapids multi-socket systems, a BPF scheduler, by # hammering on the same queue across sockets, could live-lock the # system to the point where the system couldn't make reasonable forward # progress. # # This could lead to soft-lockup triggered resets or stalling out # bypass mode switch and thus BPF scheduler ejection for tens of # minutes if not hours. After trying a number of mitigations, the # following set worked reliably: # # - Injecting artificial cpu_relax() loops in two places while # sched_ext is trying to turn on the bypass mode. # # - Triggering scheduler ejection when soft-lockup detection is # imminent (a quarter of threshold left). # # While not the prettiest, the impact both in terms of code complexity # and overhead is minimal. # # - A common complaint on the API is the overuse of the word "dispatch" # and the confusion around "consume". This is due to how the dispatch # queues became more generic over time. Rename the affected kfuncs for # clarity. Thanks to BPF's compatibility features, this change can be # made in a way that's both forward and backward compatible. The # compatibility code will be dropped in a few releases. # # - Other misc changes # # * tag 'sched_ext-for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: (21 commits) # sched_ext: Replace scx_next_task_picked() with switch_class() in comment # sched_ext: Rename scx_bpf_dispatch[_vtime]_from_dsq() -> scx_bpf_dsq_move[_vtime]() # sched_ext: Rename scx_bpf_consume() to scx_bpf_dsq_move_to_local() # sched_ext: Rename scx_bpf_dispatch[_vtime]() to scx_bpf_dsq_insert[_vtime]() # sched_ext: scx_bpf_dispatch_from_dsq_set_*() are allowed from unlocked context # sched_ext: add a missing rcu_read_lock/unlock pair at scx_select_cpu_dfl() # sched_ext: Clarify sched_ext_ops table for userland scheduler # sched_ext: Enable the ops breather and eject BPF scheduler on softlockup # sched_ext: Avoid live-locking bypass mode switching # sched_ext: Fix incorrect use of bitwise AND # sched_ext: Do not enable LLC/NUMA optimizations when domains overlap # sched_ext: Introduce NUMA awareness to the default idle selection policy # sched_ext: Replace set_arg_maybe_null() with __nullable CFI stub tags # sched_ext: Rename CFI stubs to names that are recognized by BPF # sched_ext: Introduce LLC awareness to the default idle selection policy # sched_ext: Clarify ops.select_cpu() for single-CPU tasks # sched_ext: improve WAKE_SYNC behavior for default idle CPU selection # sched_ext: Use btf_ids to resolve task_struct # sched/ext: Use tg_cgroup() to elieminate duplicate code # sched/ext: Fix unmatch trailing comment of CONFIG_EXT_GROUP_SCHED # ... # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux-ld --version # < git log --format=%s --max-count=1 8f7c8b88bda4988f44e595a760438febf51c92c8 # make -s -j 160 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux- axs103_smp_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # < make -s -j 160 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux- help # make -s -j 160 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux- olddefconfig # make -s -j 160 ARCH=arc O=/kisskb/build/linus_axs103_smp_defconfig_arc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/arc-linux/bin/arc-linux- /kisskb/src/arch/arc/boot/dts/axc003_idu.dtsi:92.16-97.5: Warning (interrupt_provider): /cpu_card/pct: '#interrupt-cells' found, but node is not an interrupt provider /kisskb/src/arch/arc/boot/dts/axc003_idu.dtsi:109.18-111.5: Warning (interrupt_provider): /axs10x_mb/ethernet@18000: '#interrupt-cells' found, but node is not an interrupt provider also defined at /kisskb/src/arch/arc/boot/dts/axs10x_mb.dtsi:73.24-88.5 arch/arc/boot/dts/axs103_idu.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' /kisskb/src/drivers/base/regmap/regcache-maple.c: In function 'regcache_maple_drop': /kisskb/src/drivers/base/regmap/regcache-maple.c:115:23: warning: 'upper_index' is used uninitialized [-Wuninitialized] 115 \| unsigned long upper_index, upper_last; \| ^~~~~~~~~~~ /kisskb/src/drivers/base/regmap/regcache-maple.c:115:36: warning: 'upper_last' is used uninitialized [-Wuninitialized] 115 \| unsigned long upper_index, upper_last; \| ^~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_axs103_smp_defconfig_arc-gcc13 # Build took: 0:02:14.041840
