This is undesirable because they can trigger # any number of watchdogs while waiting for reboot, but also we don't # know what else they might be doing -- they might be causing trouble, # trampling memory, etc. # # The opal scheduled flash update code already ran into watchdog problems # due to flashing taking a long time, and it was fixed with 2196c6f1ed # ("powerpc/powernv: Return secondary CPUs to firmware before FW update"), # which returns secondaries to opal. It's been found that regular reboots # can take over 10 seconds, which can result in the hard lockup watchdog # firing, # # reboot: Restarting system # [ 360.038896709,5] OPAL: Reboot request... # Watchdog CPU:0 Hard LOCKUP # Watchdog CPU:44 detected Hard LOCKUP other CPUS:16 # Watchdog CPU:16 Hard LOCKUP # watchdog: BUG: soft lockup - CPU#16 stuck for 3s! [swapper/16:0] # # This patch removes the special case for flash update, and calls # smp_send_stop in all cases before calling reboot/shutdown. # # smp_send_stop could return CPUs to OPAL, the main reason not to is # that the request could come from a NMI that interrupts OPAL code, # so re-entry to OPAL can cause a number of problems. Putting # secondaries into simple spin loops improves the chances of a # successful reboot. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # Reviewed-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 f2748bdfe157343eb8cf910a1d89ccf2fd20100b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+NO_TM_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # Added to kconfig CONFIG_PPC_TRANSACTIONAL_MEM=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+NO_TM_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64_defconfig+NO_TM_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: modpost: Found 2 section mismatch(es).
