Hi Peter,
This mini-series adds perf support for ARCv2 based cores, which brings in
overflow interupts and SMP. Additionally now raw events are supported as well.
Please review !
Compared to v2 this series has:
[1] Removed patch with raw-events support.
It needs some rework and let's then
This generalization prepares for support of overflow interrupts.
Hardware event counters on ARC work that way:
Each counter counts from programmed start value (set in
ARC_REG_PCT_COUNT) to a limit value (set in ARC_REG_PCT_INT_CNT) and
once limit value is reached this timer generates an interrupt.

Hi Peter and Ingo and everybody,
Here's an update of my extended error reporting patchset, addressing
review comments and adding a few more error messages to PT and BTS
drivers.
Changes since v1:
* addressed Peter's comments,
* added perf_err() annotation to intel_pt and intel_bts drivers;
If kernel debugging is enabled, include additional information to extended
syscall error reports: file name and line number, to make error hunting even
easier.
And in really desperate times, this allows for such things (a variation on
Hugh Dickins' trick [1]):
#undef EINVAL

It has been pointed several times out that perf syscall error reporting
leaves a lot to be desired [1].

to annotate their error codes with arbitrary strings, which will then
be copied to userspace (if they asked for it) along w

Hi Daniel,
