Re: xen + debian packages + megaraid driver

[Patrick Paul]

I second that.  I noticed PCI was off by default on a build I was 
working with a couple of weeks back right after the first FUDCON.  Weird 
that kernels on x86 would ever have defaults of no-PCI.  Official 
feature request perhaps?

Not sure what's going on here, but I just checked our xen-2.0-testing
tree and all the low level drivers are available on the config menu
(including both the nexgen and legacy megaraid drivers). Maybe this is
specific to the debian patch.

Sounds like you havent enabled Priviliged Operation (Domain 0) under the
XEN options in menuconfig. Also choose "Physical device access".

Hope this helps

I've checked the kernel config options under XEN, and "Privileged Guest
(domain 0)" is checked. This makes "Physical device access" show up, but
it's not selectable (should it be?).

A "grep XEN .config" on my toplevel shows:

CONFIG_XEN=y
CONFIG_ARCH_XEN=y
# XEN
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PHYSDEV_ACCESS=y
CONFIG_XEN_BLKDEV_BACKEND=y
CONFIG_XEN_NETDEV_BACKEND=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
# CONFIG_XEN_NETDEV_FRONTEND_PIPELINED_TRANSMITTER is not set
CONFIG_XEN_WRITABLE_PAGETABLES=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XENARCH="i386"

while in the SCSI section I have:
CONFIG_SCSI=y
CONFIG_SCSI_PROC_FS=y

and everything else is "not set".

Re: xen + debian packages + megaraid driver

[michal urbanski]

For anyone who may be marginally interested in my problem, I've
broadened the scope to include all 2.6.10 kernels (not just the
Debianized ones) and the patches that come with xen-2.0.4-src.tgz

Is *anyone* running xen on a machine with a RAID device? I'm assuming
yes; how did you do it? Do you have to use an initrd? Even if so, what
magic kernel configuration did you use to get the driver built?

Thanks for any help... this situation is really puzzling.

Sigh. Many apologies to all who spent time helping me with this. For
whatever reason, under Bus Option, PCI had been turned off. An odd
default, imo, but there you go.

Thank you, everyone. Am looking forward to finally working with this
cool tech :)

xen + debian packages + megaraid driver

[michal urbanski]

Hello all,

My problem is that I'm unable to compile in support for a megaraid
device into my domain0 kernel. What follows is the detailed description
of my problem:


I'm trying to make a domain0 2.6.10 kernel for a Dell SMP box, and as
such I need to have the megaraid driver compiled in. I found some
semi-official looking debian [1]packages for xen 2.0.4, and this is the
process I followed:

1) installed fresh kernel sources for 2.6.10
2) instaled those debian packages for xen
3) ran /usr/src/kernel-patches/i386/apply/xen to patch vanilla sources
4) did "make ARCH=xen menuconfig" at source toplevel to configure kernel

now, at this stage, I was unable to select the driver I wanted from
device drivers->scsi device support->scsi lowlevel drivers. Normally,
this is where one finds the megaraid driver, but after applying the xen
patches, almost no lowlevel scsi drivers are available (nothing, except
for "Serial ATA Support" and "SCSI Debugging Host Simulator".

Now, is my problem a faulty kernel patch, or do I have to do something
else to get the megaraid driver compiled in? The kernel that I have been
able to build boots fine, except for not being to find my root dir, due
to it being on that raid device.

Here's the snippet from my /boot/grub/menu.lst just in case this is the
problem:

title           Xen 2.0
root            (hd0,0)
kernel          (hd0,0)/boot/xen.gz dom0_mem=131072 noreboot
module          (hd0,0)/boot/vmlinuz-2.6.10-xen0.3 root=/dev/sda3 ro
console=tty0

Thanks for any help that you are able to provide. Also, if this not the
appropriate place for this question, please let me know. I looked for a
xen-user list, but either a) it doesn't exist or b) is highly hidden
from riffraff such as myself :)
