Hi,
This series introduces AUX data sampling for perf events, which in

ETM means execution flow history leading up to a perf event's

In case of Intel PT, this can be used as an alternative to LBR, with

The time spent under interrupt can be significant but it is not reflected
in the utilization of CPU when deciding to choose an OPP. Now that we have
access to this metric, schedutil can take it into account when selecting
the OPP for a CPU.

We can't call function trace hook before setup percpu offset.
When entering secondary_start_kernel(), percpu offset has not
been initialized. So this lead hotplug malfunction.

Marc, is the patch supposed to show up on
https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/log/
or am I looking at the wrong tree?
Thanks,

On newer Intel platforms, ASPM support in r8169 is the last missing
puzzle to let Package C-State achieves PC8. Without ASPM support, the
deepest Package C-State can hit is PC3.
PC8 can save additional ~3W in comparison with PC3 on my testing
platform.
The original patch is from Realtek.
