        Oh. So, how should I read it now then? Probably something in sysfs, but "grep MHz /proc/cpuinfo" was pretty simple to me.

            My USB Broadcom bluetooth dongle is still broken since early 4.12 release candidates, I was hoping the Broadcom/usb updates I saw in the kernel today/yesterday might have fixed it.

              it will probably now state the retail mhz instread of current mhz. as how it should be.

                Yes, but I tried to ask how can I read the current frequency now that /proc/cpuinfo doesn't tell it anymore.

                  depends on your distro as there are several tools to do that.. just google it?

                    Code:
                    cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
                    Not very easy to remember and requires root user. I can always alias this, but it would still require sudo. lscpu command seems to be able to see this without elevating privileges, so there should be a way to do it without root.
