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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 950b07c14e8c59444e2359f15fd70ed5112e11a0 # < make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0x7C81B938 # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # yes \n \| make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 24 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:38: LSE atomics not supported by binutils arch/arm64/Makefile:38: LSE atomics not supported by binutils /kisskb/src/lib/test_rhashtable.c: In function 'test_rhltable': /kisskb/src/lib/test_rhashtable.c:446:1: warning: the frame size of 2176 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ /kisskb/src/drivers/soundwire/slave.c:16:12: warning: 'sdw_slave_add' defined but not used [-Wunused-function] static int sdw_slave_add(struct sdw_bus *bus, ^ Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 # Build took: 0:05:48.964156
