In # particular, it breaks offlining and then re-onlining the boot CPU, which # we treat specially (and the BIOS does too). # # The symptoms are that we can offline the CPU, but it then does not come # back online again: # # smpboot: CPU 0 is now offline # smpboot: Booting Node 0 Processor 0 APIC 0x0 # smpboot: do_boot_cpu failed(-1) to wakeup CPU#0 # # Thomas says he knows why it's broken (my personal suspicion: our magic # handling of the "cpu0_logical_apicid" thing), but for 5.3 the right fix # is to just revert it, since we've never touched the LDR bits before, and # it's not worth the risk to do anything else at this stage. # # [ Hotpluging of the boot CPU is special anyway, and should be off by # default. See the "BOOTPARAM_HOTPLUG_CPU0" config option and the # cpu0_hotplug kernel parameter. # # In general you should not do it, and it has various known limitations # (hibernate and suspend require the boot CPU, for example). # # But it should work, even if the boot CPU is special and needs careful # treatment - Linus ] # # Link: https://lore.kernel.org/lkml/156785100521.13300.14461504732265570003@skylake-alporthouse-com/ # Reported-by: Chris Wilson <chris@chris-wilson.co.uk> # Acked-by: Thomas Gleixner <tglx@linutronix.de> # Cc: Bandan Das <bsd@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-ld --version # < git log --format=%s --max-count=1 950b07c14e8c59444e2359f15fd70ed5112e11a0 # < make -s -j 32 ARCH=nds32 O=/kisskb/build/linus_nds32-allyesconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allyesconfig # make -s -j 32 ARCH=nds32 O=/kisskb/build/linus_nds32-allyesconfig_nds32le CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
