FIASCO_INIT void Cpu::identify (   )  [static]
 

Identify the CPU features.

Attention: This function may be called more than once. The reason is that enabling a Local APIC that was previously disabled by the BIOS may change the processor features. Therefore, this function has to be called again after the Local APIC was enabled.
