The testcase uses event code 0x500fa ("instructions") to check the CC56RUN bit setting in Monitor Mode Control Register 0(MMCR0). In ISA v3.1 platform, this bit is expected to be set in MMCR0 when using Performance Monitor Counter 5 and 6 (PMC5 and PMC6). Verify this is done correctly by perf interface. CC56RUN bit makes PMC5 and PMC6 count regardless of the run latch state. This bit is set in power10 since PMC5 and PMC6 is used in power10 for counting instructions and cycles. Hence added a check to skip this test in other platforms Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> [mpe: Add error checking, drop GET_MMCR_FIELD, add to .gitignore] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20220127072012.662451-11-kjain@linux.ibm.com |
