T1 and e1000g

Enabling e1000g
==============

The Ontario motherboard has Intel Ophir chip that can be used with ipge or e1000g network drivers.
Typically the factory default driver is ipge. If you want to exercise the e1000g driverinstead of
the ipge, please follow the following steps.

How to switch to e1000g driver from factory default ipge driver:
========================================================
1) Edit /etc/rc2.d/S99bench. Plumb e1000g and comment out the plumbing of ipge.
using the command ifconfig e1000g plumb

2) In a separate window on the same machine, run, prtconf -pv and see what
compatible vendor ids are shown for the network interface
You will see entries such as :
>>
compatible: 'pciex8086,105e.108e.105e.6' + 'pciex8086,105e.108e.105e' +
'pciex8086,105e.6' + 'pciex8086,105e' + 'pciexclass,020000' +
'pciexclass,0200'
<<

Check the driver aliases file for ipge entries. You will see values such as :
ipge "pciex8086,105e"
ipge "pciex8086,105f"
ipge "pci8086,105e"
ipge "pci8086,105f"

Check if any of these vendor ids match with vendor-product ids already listed
for e1000g driver. Backup /etc/driver_aliases file to /etc/driver_aliases.ipge Replace all ipge to e1000g in /etc/driver_aliases

3)
Backup original /etc/path_to_inst file to path_to_inst.ipge.
Now, change all the ipge entries in path_to_inst file to e1000g.
Note: the port numbers change too.

port 1 e1000g --> port 0 ipge
port 3 e1000g --> port 1 ipge
port 0 e1000g --> port 2 ipge
port 2 e1000g --> port 3 ipge

Check out the diff below and edit your path_to_inst accordingly.

testmachine> diff path_to_inst path_to_inst.ipge

< "/pci@780/pci@0/pci@1/network@0" 1 "e1000g"
< "/pci@780/pci@0/pci@1/network@0,1" 3 "e1000g"

> "/pci@780/pci@0/pci@1/network@0" 0 "ipge"

> "/pci@780/pci@0/pci@1/network@0,1" 1 "ipge"

< "/pci@7c0/pci@0/pci@1/network@0" 0 "e1000g"
< "/pci@7c0/pci@0/pci@1/network@0,1" 2 "e1000g"

> "/pci@7c0/pci@0/pci@1/network@0" 2 "ipge"

> "/pci@7c0/pci@0/pci@1/network@0,1" 3 "ipge"

4) Copy /etc/hostname.ipge2 to /etc/hostname.ipge2.bak
Rename /etc/hostname.ipge2 to hostname.e1000g0

5) Reboot the machine

6) When the machine comes up now, run ifconfig -a. You should be able to see
e1000g0
7) Check the inet and netmask for e1000g0 and correct it if necessary

8) Plumb other ports and set inet and netmasks for them also using:
#ifconfig e1000g0 inet netmask up
9) Setup default gateway (Get default gateway using netstat -nr)
#route add default

10) Check cables and make sure leds are green
You should now be able to ping through e1000g on all the interfaces


How to use a new e1000g driver on factory installed Ontario:
=============================================================

Obtain the latest e1000g driver files: e1000g and e1000g.conf
(You may want to contact the e1000g driver team)


1) Copy driver and conf file.
copy e1000g binary to /kernel/drv/sparcv9/
copy e1000g.conf file to /kernel/drv/

2) Backup /etc/driver_aliases to /etc/driver_aliases.ipge

3) Modify /etc/driver_alias

4) Replace all the ipge to e1000g.

5) Backup /etc/path_to_inst to /etc/path_to_inst.ipge

6) Modify /etc/path_to_inst by replacing ipge with e1000g.
Note, the port numbers will change too.
Port for ipge1 becomes e1000g3 and ipge2 becomes e1000g0.

7) Modify /etc/name_to_major. Add a line at end "e1000g 267".
(Go to the last line and select the number that is consecutively higher).

8) Run: touch /reconfigure

9) cp /etc/hostname.ipge2 /etc/hostname.e1000g0
10) Edit /etc/rc2.d/S99bench to plumb e1000g and comment out ipge.
11) Reboot machine.

12) When the machine comes up now, run ifconfig -a. You should be able to see
e1000g entry

13) Check the inet and netmask for e1000g0 and correct it if necessary

14) Plumb other ports and set inet and netmasks for them also using:
#ifconfig e1000g0 inet netmask up

15) Setup default gateway (Get default gateway using netstat -nr)
#route add default

16) Check cables and make sure leds are green
You should now be able to ping through e1000g on all the interfaces
