Hi Canonical,
In order to enable Ubuntu to read the PMU properly on a POWER9 system,
the following commits are required:
a2391b35f1 powerpc/perf: use is_kernel_addr macro in perf_get_misc_flags()
78a16d9fc1 powerpc/perf: Avoid FAB_*_MATCH checks for power9
8d911904f3 powerpc/perf: Add restrictions to PMC5 in power9 DD1
356d8ce3d0 powerpc/perf: Use Instruction Counter value
8a088542c8 powerpc/perf: Use PM_INST_DISP for generic instructions sample
a114aca57a powerpc/perf: Add alternative event table and function for power9
ac19670eb1 powerpc/perf: Add PM_INST_DISP event to Power9 event list
efe881afdd powerpc/perf: Factor out event_alternative function
We need to have these patches in the kernel if we want to use perf, for
example.
