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-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 07a361072378fb3ae116db86244372dbd68f9ea3 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc5200_defconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S: Assembler messages: /kisskb/src/arch/powerpc/platforms/52xx/lite5200_sleep.S:184: Warning: invalid register expression INFO: Uncompressed kernel (size 0x864b18) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x864b18) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x864b18) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) INFO: Uncompressed kernel (size 0x85453c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Image Name: Linux-5.12.0-rc3-g07a361072378 Created: Sun Mar 28 02:57:34 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3824508 Bytes = 3734.87 KiB = 3.65 MiB Load Address: 00900000 Entry Point: 00900284 Image Name: Linux-5.12.0-rc3-g07a361072378 Created: Sun Mar 28 02:57:34 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3796439 Bytes = 3707.46 KiB = 3.62 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.12.0-rc3-g07a361072378 Created: Sun Mar 28 02:57:34 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3825221 Bytes = 3735.57 KiB = 3.65 MiB Load Address: 00900000 Entry Point: 00900284 Image Name: Linux-5.12.0-rc3-g07a361072378 Created: Sun Mar 28 02:57:34 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 3825203 Bytes = 3735.55 KiB = 3.65 MiB Load Address: 00900000 Entry Point: 00900284 Completed OK # rm -rf /kisskb/build/powerpc-next_mpc5200_defconfig_powerpc-gcc5 # Build took: 0:01:22.294927
