Somewhat confused. In include/asm-i386/cpufeature.h we have: --snip-- #define X86_FEATURE_XMM2 (0*32+26) /* Streaming SIMD Extensions-2 */ #define X86_FEATURE_SELFSNOOP (0*32+27) /* CPU self snoop */ #define X86_FEATURE_HT (0*32+28) /* Hyper-Threading */ #define X86_FEATURE_ACC (0*32+29) /* Automatic clock control */ <---- ****** #define X86_FEATURE_IA64 (0*32+30) /* IA-64 processor */ --end snip--
According to Intel specs, bit 29 is : " TM Thermal Monitor The processor implements the thermal monitor automatic thermal control circuitry (TMM)"
The (wrong?) FEATURE ACC is used in arch/i386/kernel/cpu/cpufreq/p4-clockmod.c arch/i386/kernel/cpu/mcheck/p4.c
