set_cx86_inc was one of performance trick called by geode_configure I didn't find any documentation about "incrementor margin" before. But since I'm running on 300MHz GX1 the default kernel is now broken for me! > --- linux-2.6.22.orig/arch/i386/kernel/cpu/cyrix.c > +++ linux-2.6.22/arch/i386/kernel/cpu/cyrix.c > @@ -169,7 +169,7 @@ static void __cpuinit set_cx86_inc(void) > setCx86(CX86_PCR1, getCx86(CX86_PCR1) | 0x02); > /* PCR0 -- Performance Control */ > /* Incrementor Margin 10 */ > - setCx86(CX86_PCR0, getCx86(CX86_PCR0) | 0x04); > + setCx86(CX86_PCR0, getCx86(CX86_PCR0) | 0x05); /* 300MHz CPU */ > setCx86(CX86_CCR3, ccr3); /* disable MAPEN */ > } > I will try your patch But again, if those tricks are so system dependent I suggest to kernel people to let disable it in default configuration.
