Hi there,
I'm trying to disable the printk time stamp by appending printk.time=0
in the grub, but it seems not work, dmesg always shows the timestap.
Do I miss something? thanks.

The original problem comes from a bug found on MacBookPro that,

A new flag is introduced to indicate that, we are in the process of

Sometimes it is too late for the APs to synchronize the MTRR
after all the APs have been brought up. In some cases the BIOS
might scribble the MTRR across suspend/resume, as a result we
might get insane MTRR after resumed back, thus every instruction
run on this AP would be extremel
From: Chen Yu
We record the cpu which has issued the MTRR setting command, then
in the mtrr_rendezvous_handler() we can distinguish it from the
other cpus. This is used for MTRR synchronization optimization.

There's a use case during test to only print specific round of loops
if --iterations is specified, for example, with this patch applied:
turbostat -i 5 -t 4
