Hi,For ARM cortex A76, A77, A78 cores (which as per TRM, support AMU) AA64PFR0[47:44] field is not set, and AMU does not get enabled for them.
Can you please provide support for these CPUs in cpufeature.c? Thanks Neeraj --QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, hosted by The Linux Foundation
