Well, at least the front-end side is still documented in the SDM as being
usable to count stalled cycles.
Stalled frontend cycles does not necessarily mean frontend bound.
The real bottleneck can be still somewhere later in the PipeLine.
Out of Order CPUs are complex.

I am not sure how to call this kernel option but we need something like
that. I see drivers and the kernel spawning processes on the nohz cores.
The name kthread is not really catching the purpose.

That said, another thing that strikes me is that you have 32 CPU

16. Did you change that? Becuase if not, then some of the extreme

Add a test for parsing a non-sample event when there is more than one

The test fails because of a bug in the evlist logic. That is fixed in a

Hi,
It's a great topic! I am glad to see this conversation happening...

There is currently no way for kernel code to determine whether it

whether or not RCU is paying attention to the currently running CPU.
