Fixed by splitting the queue used for FIFO # scheduling per NUMA node. This required several preparation patches. # # - Hotplug tests on powerpc could reliably trigger deadlock while # enabling a BPF scheduler. # # This was caused by cpu_hotplug_lock nesting inside scx_fork_rwsem and # then CPU hotplug path trying to fork a new thread while holding # cpu_hotplug_lock. # # Fixed by restructuring locking in enable and disable paths so that # the two locks are not coupled. This required several preparation # patches which also fixed a couple other issues in the enable path. # # - A build fix for !CONFIG_SMP # # - Userspace tooling sync and updates # # * tag 'sched_ext-for-6.12-rc1-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext: # sched_ext: Remove redundant p->nr_cpus_allowed checker # sched_ext: Decouple locks in scx_ops_enable() # sched_ext: Decouple locks in scx_ops_disable_workfn() # sched_ext: Add scx_cgroup_enabled to gate cgroup operations and fix scx_tg_online() # sched_ext: Enable scx_ops_init_task() separately # sched_ext: Fix SCX_TASK_INIT -> SCX_TASK_READY transitions in scx_ops_enable() # sched_ext: Initialize in bypass mode # sched_ext: Remove SCX_OPS_PREPPING # sched_ext: Relocate check_hotplug_seq() call in scx_ops_enable() # sched_ext: Use shorter slice while bypassing # sched_ext: Split the global DSQ per NUMA node # sched_ext: Relocate find_user_dsq() # sched_ext: Allow only user DSQs for scx_bpf_consume(), scx_bpf_dsq_nr_queued() and bpf_iter_scx_dsq_new() # scx_flatcg: Use a user DSQ for fallback instead of SCX_DSQ_GLOBAL # tools/sched_ext: Receive misc updates from SCX repo # sched_ext: Add __COMPAT helpers for features added during v6.12 devel cycle # sched_ext: Build fix for !CONFIG_SMP # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e32cde8d2bd7d251a8f9b434143977ddf13dcec6 # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64le_defconfig Using /kisskb/src/arch/powerpc/configs/ppc64_defconfig as base Merging /kisskb/src/arch/powerpc/configs/le.config # # merged configuration written to .config (needs make) # # < make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/linus_ppc64le_defconfig_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/linus_ppc64le_defconfig_powerpc-gcc13 # Build took: 0:02:22.305853
