Hi,
I am exploring the CPUID instruction.
I can read the vendorID, and CPU-flags successfully.
When I try to read the CPU serial number I get zeros.
I checked the 18-th bit of the CPU-flags, and it appeared that it is not
set, which means this option is disabled.
(/proc/cpuinfo tells the same)
I read in the archives that I need pass the serialnumber as an option at
boot time. I did so, and still it was the same.
I believe this functionality exists in the CPU, as the cpuid_level is 5.
can anyone offer help?
Is "serialnumber' the correct option name? I have't found it documented
anywhere.
Hayim.
