Re: FreeBSD WOL sis on


Hey David,

Have an Intel ITX size board (D201GLY2) with a SiS 900

using ethtool in Linux.

Am not a BSD user, but am attracted to the FreeNAS
project which has recently integrated your WOL patch
(hopefully a recent version).

The sis driver supports at least two different types
of cards.

What does dmesg print for your card? I have only one type of
NIC the sis driver supports and have only implemented support
for this one:

sis0: <NatSemi DP8381[56] 10/100BaseTX> port 0xac00-0xacff mem
0xdb001000-0xdb00
sis0: Silicon Revision: DP83816A

From userspace it
appears ready to set the NIC to wake (i.e. ifconfig
returns "will wake on: magic"), but the system ignores
magic packets and does not wake from FreeBSD.

If the card type isn't a DP83815 or DP83816, this is a bug.
The driver should not let you configure cards for WOL
it has no support for.

Have verified that there is no reconfiguration of the
adapter as part of the FreeNAS shutdown scripts. I see
that your patch integrates changes to this driver, so
maybe you might have seen the issue on other
platforms? Any ideas where to look as a next step--
would appear to be something in if_sis that is not
working on this board?

There are many things that can go wrong with WOL.

Here's a quick checklist (the first three are probably
not causing your problem because you've verified that
WOL works with Linux):

Is the WOL cable plugged in properly (if needed)?

Are BIOS WOL settings OK?

Is ACPI enabled (in BIOS and OS)?

Have you used "shutdown -p" to shut down the box?
Using "shutdown -h" or "halt" and then turning the
power off might not work (at least I've never tried this...)

Does the card enter D3 sleep mode properly after the box
shuts down, i.e. does a NIC LED stay on after shutdown?

Do "wake" packets (e.g. magic packets) actually reach the box?
To find out, I do:
while true; do wol -h 10.42.42.255 <mac addr>; sleep 1; done
and then if the box doesn't wake up I look at the NIC LEDS to
check for periodic blinking of the tx/rx LED.
Adjust the broadcast IP address to your network of course.

Hope this helps,
