SMT_ID or APIC_ID caching

2005-09-02 Thread Wilkerson, Bryan P
On a P4 with HT, I'm trying to get the logical processor ID (SMT_ID) for the currently executing thread in kernel mode. The SMT_ID is part of the APIC_ID which is in EBX[24:16] after calling cpuid with EAX=1. Is the SMT_ID or APIC_ID per_cpu cached by the kernel anywhere? Thanks, -bryan - To u

[PATCH 2/3] dyntick - Fix lost tick calculation in timer pm.c
