[Xen-users] Problem compile xen+DAC960

[Torsten lehmann <tlehmann@xxxxxxxxxxxxx>]

Hello!

I have a system with Raid-Controller Mylex (DAC960).
Linux 2.6.11.8 #1 SMP is running.

Now i want to install Xen-2.0-src,
but CONFIG_BLK_DEV_DAC960 is deleted after running "make ARCH=xen ...."
(Details s. prob_config_DAC)

Questions:
- How can I fixed prob_config_DAC?
- How can I find a usable compile-instructions for different hardware?
- How can I patch linux-kernel correctly? (patch or copy) Which is the
  best one?


Regards Torsten

PS: If you want: I can sent the hole documents:

  - Problem: einige Einstellunng (DAC960) sind nach "make ARCH=xen ..."
weg.

linux-2.6.11-xen0# cp /usr/src/linux/.config .
linux-2.6.11-xen0# grep DAC .config
CONFIG_BLK_DEV_DAC960=y
linux-2.6.11-xen0# make ARCH=xen oldconfig
linux-2.6.11-xen0# grep DAC .config
linux-2.6.11-xen0#
  - Einstellung ist weg...
  -> damit kann niemals der Kernel mit DAC960 erzeugt werden
