Subject: 2.5.51 cpufeatures.h
Date: Sat, 14 Dec 2002 12:55:55 +0100 [thread overview]
Message-ID: <4.3.2.7.2.20021214124403.00ae5f00@pop.t-online.de> (raw)
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
