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/ #
