An EPOW-aware OS logs the EPOW error # log information, then schedules the system to be shut down to begin # after an OS defined delay internal (default is 10 minutes.) # # Then in section 10.3.2.2.8 there is table 146 "Platform Event Log # Format, Version 6, EPOW Section", which includes the "EPOW Event # Modifier": # # For EPOW sensor value = 3 # 0x01 = Normal system shutdown with no additional delay # 0x02 = Loss of utility power, system is running on UPS/Battery # 0x03 = Loss of system critical functions, system should be shutdown # 0x04 = Ambient temperature too high # All other values = reserved # # We have a user space tool (rtas_errd) on LPAR to monitor for # EPOW_SHUTDOWN_ON_UPS. Once it gets an event it initiates shutdown # after predefined time. It also starts monitoring for any new EPOW # events. If it receives "Power restored" event before predefined time # it will cancel the shutdown. Otherwise after predefined time it will # shutdown the system. # # Commit 79872e35469b ("powerpc/pseries: All events of # EPOW_SYSTEM_SHUTDOWN must initiate shutdown") changed our handling of # the "on UPS/Battery" case, to immediately shutdown the system. This # breaks existing setups that rely on the userspace tool to delay # shutdown and let the system run on the UPS. # # Fixes: 79872e35469b ("powerpc/pseries: All events of EPOW_SYSTEM_SHUTDOWN must initiate shutdown") # Cc: stable@vger.kernel.org # v4.0+ # Signed-off-by: Vasant Hegde <hegdevasant@linux.vnet.ibm.com> # [mpe: Massage change log and add PAPR references] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200820061844.306460-1-hegdevasant@linux.vnet.ibm.com # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 90a9b102eddf6a3f987d15f4454e26a2532c1c98 # < make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # < make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 24 ARCH=sparc64 O=/kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. kernel: arch/sparc/boot/image is ready kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/powerpc-fixes_sparc64-defconfig_sparc64 # Build took: 0:01:44.971866
