This can be observed in a # pseries QEMU guest that has hotplugged CPUs. If the user offlines all # other CPUs of the guest, and a hotplugged CPU is now the last online # CPU, trying to reclaim it will fail. # # The current error message in this situation returns rc with -EBUSY and a # generic explanation, e.g.: # # pseries-hotplug-cpu: Failed to offline CPU PowerPC,POWER9, rc: -16 # # EBUSY can be caused by other conditions, such as cpu_hotplug_disable # being true. Throwing a more specific error message for this case, # instead of just "Failed to offline CPU", makes it clearer that the error # is in fact a known error situation instead of other generic/unknown # cause. # # This patch adds a 'last online' check in dlpar_cpu_offline() to catch # the 'last online CPU' offline error, eturning a more informative error # message: # # pseries-hotplug-cpu: Unable to remove last online CPU PowerPC,POWER9 # # Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210323205056.52768-2-danielhb413@gmail.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 07a361072378fb3ae116db86244372dbd68f9ea3 # < make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- defconfig # < make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c: In function 'is1_entry_set': /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: missing braces around initializer [-Wmissing-braces] struct ocelot_vcap_u16 etype = {0}; ^ /kisskb/src/drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: (near initialization for 'etype.value') [-Wmissing-braces] WARNING: modpost: Symbol info of vmlinux is missing.
