In the last episode (Jan 10), Palle Girgensohn said:How can I programatically find out the CPU frequency?
I'm trying to port a program from Linux, and it uses /proc/cpuinfo.
$ cat /compat/linux/proc/cpuinfo cpu MHz : 349.20
Pretty neat, but it does not exist in FreeBSD, and sysctl does not give out this information. Grepping the dmesg.boot seems somewhat odd for a C program:
$ dmesg | grep -i hz Timecounter "i8254" frequency 1193182 Hz CPU: Pentium II/Pentium II Xeon/Celeron (349.20-MHz 686-class CPU)
I think someone suggested that more CPU information be exported via sysctl nodes at some point, but no-one has found it important enough to code. Note that on laptops and many ACPI motherboards, you can tweak the CPU speed on the fly, so you can't just store the bootup value. Other architectures may also allow multiple CPUs at different speeds.
As for your issue, I'd say just comment the code out. Do you really need to know the CPU speed? Another option is to shell out and run cpuid or x86info, but those are x86-only, of course.
