Hi,
I recently acquired one of these motherboards and suitable CPU + memory for it.
The on-board 3com MAC and Broadcom/Altima PHY are not being detected by the
xl(4) driver in -current (cvsup done yesterday evening).
In the Award BIOS there is only one setting for the 3com device, a supposed
on/off switch with only values Disabled and Auto; I have used Auto.
Output with stock drivers:
pcib2: <ACPI PCI-PCI bridge> at device 12.0 on pci0
pci2: <ACPI PCI bus> on pcib2
pci2: <network, ethernet> at device 1.0 (no driver attached)
pciconf -lv output:
none9@pci2:1:0: class=0x020000 card=0x80ab1043 chip=0x920110b7 rev=0x40 hdr=0x00
vendor = '3COM Corp, Networking Division'
class = network
subclass = ethernet
Output after adding the chip in question to if_xlreg.h and if_xl.c probe table:
pcib2: <ACPI PCI-PCI bridge> at device 12.0 on pci0
pci2: <ACPI PCI bus> on pcib2
xl1: <3Com 3c905C-TX on nVidia nForce2 chipset> port 0xb000-0xb07f mem 0xd3000000-0xd300007f irq 11 at device 1.0 on pci2
xl1: Ethernet address: 00:26:54:07:e5:95
xl1: no PHY found!
device_probe_and_attach: xl1 attach returned 6
So far, so good. The on-board PHY is a Broadcom/Altime AC101L, which is
not listed in miidevs. I added it there and to acphy_probe() just
to see if it would work. I also added a printf() to acphy_probe() to
output the mii_id1 and mii_id2 values before checking for the supported
models so that I could see if the probe was even getting that far.
Probe doesn't get that far since the printf() is never executed;
I believe probe halts in mii_phy_probe() since acphy_probe() would be
called by bus_generic_attach() if a PHY was found on the miibus and
that in turn would show up in the kernel boot messages because of the
printf() I added.
FWIW, the diff for the files mentioned is attached, in case someone wants
to continue from here.
Specifications for the Altima PHY are available at:
http://www.altimacom.com/products/ac101L.html
I could not find any specifications on nVidia site for the integration
of the 3com MAC into the nForce2 chipset; neither could I find any documents
on Asus site about the power control for the Broadcom/Altima MAC in case
it is somehow powered off by default.
Regards,
MSH
