In this patch, they adds starting_index value as '0xffffffffffffffff'. which is wrong as starting_index is of size 32 bits. Because of this, incase we try to run hv-gpci event we get error. In power9 machine: command#: perf stat -e hv_gpci/system_tlbie_count_and_time_tlbie_instructions_issued/ -C 0 -I 1000 event syntax error: '..bie_count_and_time_tlbie_instructions_issued/' \___ value too big for format, maximum is 4294967295 This patch fix this issue and changes starting_index value to '0xffffffff' After this patch: command#: perf stat -e hv_gpci/system_tlbie_count_and_time_tlbie_instructions_issued/ -C 0 -I 1000 1.000085786 1,024 hv_gpci/system_tlbie_count_and_time_tlbie_instructions_issued/ 2.000287818 1,024 hv_gpci/system_tlbie_count_and_time_tlbie_instructions_issued/ 2.439113909 17,408 hv_gpci/system_tlbie_count_and_time_tlbie_instructions_issued/ Fixes: 9e9f60108423 ("powerpc/perf/{hv-gpci, hv-common}: generate requests with counters annotated") Signed-off-by: Kajol Jain Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20201003074943.338618-1-kjain@linux.ibm.com Signed-off-by: Sasha Levin --- arch/powerpc/perf/hv-gpci-requests.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/powerpc/perf/hv-gpci-requests.h b/arch/powerpc/perf/hv-gpci-requests.h index e608f9db12ddc..8965b4463d433 100644 --- a/arch/powerpc/perf/hv-gpci-requests.h +++ b/arch/powerpc/perf/hv-gpci-requests.h @@ -95,7 +95,7 @@ REQUEST(__field(0, 8, partition_id) #define REQUEST_NAME system_performance_capabilities #define REQUEST_NUM 0x40 -#define REQUEST_IDX_KIND "starting_index=0xffffffffffffffff" +#define REQUEST_IDX_KIND "starting_index=0xffffffff" #include I(REQUEST_BEGIN) REQUEST(__field(0, 1, perf_collect_privileged) __field(0x1, 1, capability_mask) @@ -223,7 +223,7 @@ REQUEST(__field(0, 2, partition_id) #define REQUEST_NAME system_hypervisor_times #define REQUEST_NUM 0xF0 -#define REQUEST_IDX_KIND "starting_index=0xffffffffffffffff" +#define REQUEST_IDX_KIND "starting_index=0xffffffff" #include I(REQUEST_BEGIN) REQUEST(__count(0, 8, time_spent_to_dispatch_virtual_processors) __count(0x8, 8, time_spent_processing_virtual_processor_timers) @@ -234,7 +234,7 @@ REQUEST(__count(0, 8, time_spent_to_dispatch_virtual_processors) #define REQUEST_NAME system_tlbie_count_and_time #define REQUEST_NUM 0xF4 -#define REQUEST_IDX_KIND "starting_index=0xffffffffffffffff" +#define REQUEST_IDX_KIND "starting_index=0xffffffff" #include I(REQUEST_BEGIN) REQUEST(__count(0, 8, tlbie_instructions_issued) /*
