sysctl questions

["FUKAUMI Naoki" <fun%naobsd.org@localhost>]

Hi,

% sysctl machdep
machdep.console_device = ttyE0
machdep.biosbasemem = 0
machdep.biosextmem = 0
machdep.nkpde = 48
sysctl: machdep.diskinfo: sysctl() failed with Bad address

Is this a bug?

machdep.fpu_present = 1
machdep.osfxsr = 0
machdep.sse = 0
machdep.sse2 = 0

Can I use SSE/SSE2 cpu features on NetBSD/xen?

machdep.domain0.diskcookie.wd0 = 768
machdep.domain0.diskcookie.cd0 = 5632

What is this?

Thank you.
