Xen users - Aug 2005 - Compiling legacy LSI megaraid drivers (Linux 2.6.11) with xen 2.0.7?

Hi all,

	I''ve been using Xen for a while and I am trying to install it onto a 
Dell Poweredge 2950.  The 2850 uses a PERC4/Di raid on motherboard, 
which requires the LSI Legacy SCSI Raid driver to be compiled into the 
2.6.11-xen0 kernel.  I''ve been recompiling the kernel by:

1. Go into the linux-2.6.11-xen0 directory.  Select the driver using 
"make ARCH=xen menuconfig" and then finding the appropriate menu
option
(CONFIG_MEGARAID_LEGACY=y)

2.  cd ..

3.  make kernels

At some point....I get the following warnings during compilation:

CC      drivers/scsi/megaraid.o
drivers/scsi/megaraid.c: In function `issue_scb'':
drivers/scsi/megaraid.c:1132: warning: passing arg 2 of `writel'' makes 
pointer from integer without a cast

pointer from integer without a cast
drivers/scsi/megaraid.c:1370: warning: passing arg 1 of `readl'' makes 
pointer from integer without a cast



4.  go into dist/install/boot and copy the kernel to /boot

during boot of the new kernel, I never see the LSI megaraid driver 
load.  I assume that the above errors are symptoms of 
something...anyone have any ideas?  Has anyone had any problems similar 
to this?  I know I can get the RAID driver to cleanly compile and work 
under a non xen kernels....


Thanks in advance,

Navid Khalili

We are running 2850s and linux-2.6.11-xen0 using these kernel config 
options.
Why don''t you try them?

CONFIG_MEGARAID_NEWGEN
CONFIG_MEGARAID_MM
CONFIG_MEGARAID_MAILBOX

Thank you, thank you, thank you!

Oddly enough, menuconfig did not show those last two config options.  I 
have tried earlier using the nextgen but to no avail.  With those last 
two options, it worked!

Thanks,
Navid
