Incase lpar migrate from one system to another, system parameter details like chips per sockets or number of sockets might change. So, it needs to be re-initialized otherwise, these values corresponds to previous system values. This patch adds a call to 'read_sys_info_pseries()' from 'post-mobility_fixup()' to re-init the physsockets and physchips values Signed-off-by: Kajol Jain --- arch/powerpc/platforms/pseries/mobility.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/arch/powerpc/platforms/pseries/mobility.c b/arch/powerpc/platforms/pseries/mobility.c index b571285f6c14..10d982997736 100644 --- a/arch/powerpc/platforms/pseries/mobility.c +++ b/arch/powerpc/platforms/pseries/mobility.c @@ -371,6 +371,9 @@ void post_mobility_fixup(void) /* Possibly switch to a new RFI flush type */ pseries_setup_rfi_flush(); + /* Reinitialise system information for hv-24x7 */ + read_24x7_sys_info(); + return; } -- 2.18.2
