That's wrong; # powerpc's paravirt spinlock code uses H_PROD, and CPUs entering # do_join() can be woken prematurely from H_JOIN with a status of # H_SUCCESS as a result. This causes all CPUs to exit the sequence # early, preventing suspend from occurring at all. # # Add a 'done' boolean flag to the pseries_suspend_info struct, and have # the waking thread set it before waking the other threads. Threads # which receive H_SUCCESS from H_JOIN retry if the 'done' flag is still # unset. # # Fixes: 9327dc0aeef3 ("powerpc/pseries/mobility: use stop_machine for join/suspend") # Signed-off-by: Nathan Lynch <nathanl@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210315080045.460331-3-nathanl@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 274cb1ca2e7ce02cab56f5f4c61a74aeb566f931 # < make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # < make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 48 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 # Build took: 0:04:56.825822
