Currently 'make help' message has such hint:

But this is misleading, when I specify "prefix=/usr/local", it has got no
respect at all. Instead, what takes effect is the "DESTDIR"

When large directory feathure is enable, We have one case which could cause
overflow in dir_buckets() as following:
special case: level + dir_level >= 32 and level < MAX_DIR_HASH_DEPTH / 2.
Here we define MAX_DIR_BUCKETS to limit the return value when the condition
could trigger potential

perf stat -rX prints the stddev for multiple measurements.
Just looking at the stddev for judging the quality of the data
is a bit dangerous The simplest sanity check is to just look
at a simple plot. This patchs add a sparkline to the end
of the measurements to make it simple

This adds (in req-gen/) a framework for defining gpci counter requests.
It uses macro magic similar to ftrace.
Also convert the existing hv-gpci request structures and enum values to
use the new framework (and adjust old users of the structs and enum
values to cope with changes in naming).
In
Add the remaining gpci requests that contain counters suitable for use
by perf. Omit those that don't contain any counters (but note their
ommision).

Retrieves and parses the 24x7 catalog on POWER systems that supply it

Catalog is (at the moment) only parsed on boot. It needs re-parsing
when a some hypervisor events occur. At that point
Rather manually specifying the size of the integer to be converted, key

google is wrong.
It's standard e.g. on MacOS and imho simpler and nicer than
the usual ifdef. But I removed it.

Event parameters are a basic way for partial events to be specified in
sysfs with per-event names given to the fields that need to be filled in
when using a particular event.
It is intended for supporting cases where the single 'cpu' parameter is
insufficient. For example, POWER 8 has events for
This causes `perf list pmu` to show parameters for parameterized events
like follows:
pmu/event_name,param1=?,param2=?/ [Kernel PMU event]
An example:

(struct perf_pmu_events_attr) is defined in include/linux/perf_event.h,
but the only "show" for it is in x86 and contains x86 specific stuff.
Make a generic one for those of us who are just using the event_str.
