Currently lparstat reports which shows since LPAR boot are wrong for some fields. There is a need for storing the PIC(Pool Idle Count) at boot for accurate reporting. PATCH 1 Does that.
While there, it was noticed that hcall return value is long and both h_get_ppp and h_get_mpp could set the uninitialized values if the hcall fails. PATCH 2 does that. v1 -> v2: - Nathan pointed out the issues surrounding the h_pic call. Addressed those. - Added a pr_debug if h_pic fails during lparcfg_init - If h_pic fails while reading lparcfg, related files are not exported. - Added failure checks for h_get_mpp, h_get_ppp calls as well. v1: https://lore.kernel.org/all/20240405101340.149171-1-sshe...@linux.ibm.com/ Shrikanth Hegde (2): powerpc/pseries: Add pool idle time at LPAR boot powerpc/pseries: Add fail related checks for h_get_mpp and h_get_ppp arch/powerpc/include/asm/hvcall.h | 2 +- arch/powerpc/platforms/pseries/lpar.c | 6 ++-- arch/powerpc/platforms/pseries/lparcfg.c | 45 +++++++++++++++++------- 3 files changed, 37 insertions(+), 16 deletions(-) -- 2.39.3
