powerpc/perf: Avoid FAB_*_MATCH checks for power9
Since power9 does not support FAB_*_MATCH bits in MMCR1, avoid these checks for power9. For this, patch factor out code in isa207_get_constraint() to retain these checks only for power8. Patch also updates the comment in power9-pmu raw event encode layout to remove FAB_*_MATCH. Finally for power9, patch adds additional check for threshold events when adding the thresh mask and value in isa207_get_constraint(). fixes: 7ffd948fae4c ('powerpc/perf: factor out power8 pmu functions') fixes: 18201b204286 ('powerpc/perf: power9 raw event format encoding') Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
