perf coresight: Remove set_drv_config() API

2019-02-06T13:00:39+00:00

Now that the event's config2 attribute is used to communicate sink
selection to the kernel, remove the old set_drv_config() implementation
since it is no longer needed.

perf arm cs-etm: Use event attributes to send sink information to kernel

2019-02-06T13:00:39+00:00

The communication of sink information for a trace session doesn't work
when more than on CPU is involved in the scenario due to the static
nature of sysfs.  As such communicate the sink information to each event
by using the perf_event::attr:config2 attribute.  The information sent
to the kernel is an hash of the sink's name, which is unique in a
system.

perf map: Move structs and prototypes for map groups to a separate header

2019-02-06T13:00:38+00:00

And since machine.h only needs what is in there, make it stop including
map.h and instead include this newly introduced map_groups.h instead.

perf arm pmu: Add missing linux/string.h header

2019-02-06T13:00:38+00:00

It uses strstarts(), that is defined in linux/string.h but that was
being including by sheer luck, indirectly, fix it.

perf tests: Add a test for the ARM 32-bit [vectors] page

2019-01-08T16:28:13+00:00

perf on ARM requires CONFIG_KUSER_HELPERS to be turned on to allow some
independance with respect to the ARM CPU being used. Add a test which
tries to locate the [vectors] page, created when CONFIG_KUSER_HELPERS is
turned on to help asses the system's health.
