npx(4) MATH_EMULATE and ArinfoTek Teak3011: AMD GEODE SBC LX-800 (fwd)
I suppose this is the more appropriate list. I've found reference to the
Crypto Accelerator at:
http://www.amd.com/files/connectivitysolutions/geode/geode_lx/Patches_Linux2.6.11_Common_02.03.0100.patch
However, because Linux uses character devices and doesnt really provide
the platform independent API of crypto(9), it's hard to tell if this is
just an OEM of some other crypto accelerator IC (Intel/Via Possibly)
I looked over all of the ones supported in NetBSD and OpenBSD -- hifn(4),
ises(4), lofn(4), noct(4), nofn(4), safe(4), ubsec(4) and it doesn't seem
to mention Via/Intel OEM, so this may be new territory.

Subject: npx(4) MATH_EMULATE and ArinfoTek Teak3011: AMD GEODE SBC LX-800
FYI the dmesg(8) output from an excellent little AMD appliance I've been
testing (below).
There are only two issues:
*) The AMD crypto accelerator isn't attaching (Advanced Micro Devices
product 0x2082 (entertainment crypto) at pci0 dev 1
function 2 not configured ...)
*) What's the story with AMD GEODE processors and Numeric Processing
Extension coprocessor ? They're generally speaking "i586" chips,
but this one appears to be mapping an npx(4) device at the ISA bus,
but then fails to attach to it. Perhaps it's just a dummy device?
That brings MATH_EMULATE into question -- I presume this is software
emulation of npx(4) when no npx(4) is present?
I have to run a kernel with MATH_EMULATE enabled otherwise processes
like mount_mfs(8) crash, but I dont want to leave it enabled if it's
not a "fallback" option.
That brings up interesting questions:
- If MATH_EMULATE is present in a kernel with npx(4) enabled and probed
on a booted system, which takes precidence?
- Should this AMD GEODE be probing it's hardware npx(4) properly?
Should I contact the hardware vendor? Can I modify the npx(4) source
code to continue gracefully even if the error reporting sanity check
fails? npx.c at npxprobe1() ?
