Re: [LARTC] HZ to be 1000 - 2.5.25 may have this

Hmm, CLOCKS_PER_SEC doesn't look right, particularly if you look at include/asm-ia64/ia32.h:IA32_CLOCKS_PER_SEC. It's only used for some obscure parameter-passing mechanism in ELF, so the damage should be quite limited. (I.e. I've never noticed anything going wrong when changing HZ, and I didn't realize the CLOCKS_PER_SEC dependency until now.) - Werner -- _ / Werner Almesberger, Buenos Aires, Argentina [EMAIL PROTECTED] / /_http://icapeople.epfl.ch/almesber/_/ ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Try to download this url: http://www.ibiblio.org/gentoo/distfiles/linux-gentoo-2.4.19-crypto-r7.pa tch.bz2 This is gentoo Linux patch to 2.4.18, which adds Low Latency Scheduling, Preemptible Kernel, rmap, Ingo Molnar o(1) scheduler and by default it has HZ equal to 1000. Also there is XFS, Grsec and lots of other usefull staff. Patch is about 6.4Mbyte. Luck.

HZ is set to CONFIG_JIFFIES which defaults to 1000. Best regards, Adam Fineberg [EMAIL PROTECTED]
