The testcase uses "instructions" event to generate the samples and fetch Monitor Mode Control Register A (MMCRA) when overflow. Branch History Rolling Buffer(bhrb) disable bit is part of MMCRA which need to be verified by perf interface. Incase sample is not of branch type, bhrb disable bit is explicitly set to 1. Testcase checks if the bhrb disable bit is set of MMCRA register via perf interface for ISA v3.1 platform Signed-off-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20220610134113.62991-15-atrajeev@linux.vnet.ibm.com
