evsel__config() would only set PERF_RECORD_SAMPLE if it set attr->freq
from perf record options. When it is set by libpfm events, it would not
get set. This changes evsel__config to see if attr->freq is set outside of
whether or not it changes attr->freq itself.

For DP MST outputs, the i2c device currently only supports transfers
that can be implemented using remote i2c reads. Such transfers must
consist of zero or more write transactions followed by one read
transaction. DDC/CI commands require standalone write transactions and
hence aren't supported.

Just moving the powerpc_topology description above.
This will help in using functions in this file and avoid declarations.

Lookup the coregroup id from the associativity array.
If unable to detect the coregroup id, fallback on the core id.
This way, ensure sched_domain degenerates and an extra sched domain is
not created.
Ideally this function should have been implemented in
arch/powerpc/kernel/smp.c. However if its
A new sched_domain_topology_level was added just for Power9. However the
same can be achieved by merging powerpc_topology with power9_topology
and makes the code more simpler especially when adding a new sched
domain.

Currently "CACHE" domain happens to be the 2nd sched domain as per
powerpc_topology. This domain will collapse if cpumask of l2-cache is
same as SMT domain. However we could generalize this domain such that it
could mean either be a "CACHE" domain or a "BIGCORE" domain.
While setting up the "CACHE
Add percpu coregroup maps and masks to create coregroup domain.
If a coregroup doesn't exist, the coregroup domain will be degenerated
in favour of SMT/CACHE domain.

Current code assumes that cpumask of cpus sharing a l2-cache mask will
always be a superset of cpu_sibling_mask.
Lets stop that assumption. cpu_l2_cache_mask is a superset of
cpu_sibling_mask if and only if shared_caches is set.
