Installation of the PM/Ethernet without kernel patch driver (PM/Ethernet-nkp)

Limitation

• This is a preliminary release version
• currently supports the e1000 and tg3 drivers.

Installation

1. PM kernel drivers are on /opt/score/score-src/kernel/linux2.6.11/drivers/score-pm. Copy whole of the score-pm directory to a kernel directory (ex /usr/src/linux2.6.xx/drivers)that you install.

2. Add the following line to the bottom of /usr/src/linux2.6.xx/drivers/Kconfig

   source "drivers/score-pm/Kconfig"

3. Add the following line to the bottom of /usr/src/linux2.6.xx/drivers/Makefile

   obj-$(CONFIG_SCORE_PM) += score-pm/

4. Select the following kernel module for the PM/Ethernet-nkp on kernel configuration (ex: make menuconfig),

   < M > SCore PM/Ethernet-nkp drivers (w/o Kernel Patch)
   (4) Max units of PM/Ethernet
   Ethernet Drivers for SCore PM/Ethernet-nkp --->
   

5. Select Ethernet Drivers on the following tab

   Ethernet Drivers for SCore PM/Ethernet-nkp --->
   " < M > E1000 driver for PM/Ethernet-nkp"
   " < M > E100 driver for PM/Ethernet-nkp"
   " < M > tg3 driver for PM/Ethernet-nkp"
   

6. Compile and install the kernel and device driver modules.

   # make bzImage
   # make modules
   # make modules_install
   # make install
   

7. After reboot using the installation kernel. Change the original Ethernet device driver to Ethernet device driver of PM/Ethernet-nkp to modify /etc/modprobe.conf.

   Ex
   "alias eth0 e1000" to "alias eth0 e1000_scorepm1"
   "alias eth0 tg3" to "alias eth0 e1000_scorepm1"
   

8. After reboot the nodes, do an existing PM/Ethernet setup such as executinog /etc/init.d/pm_ethernet start
