[Xen-users] Trying to compile IT821X driver for 2.6.18 -- but can't configure it

[Bruce McKenzie <brucem@xxxxxxxxxxxxxxxx>]

Sorry if this is too linux-kernely, but I thought I should start here.

I was formerly using Xen 3.2 / 2.6.21 (gentoo) as my dom0. 

It permitted me to configure and compile the IT821X driver that I need for my disk controller: (this output from a non-Xen 2.6.25 kernel)

---------

11:04.0 Mass storage controller: Integrated Technology Express, Inc. IT/ITE8212 Dual channel ATA RAID controller (rev 13)

Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 23

I/O ports at 2448 [size=8]

I/O ports at 243c [size=4]

I/O ports at 2440 [size=8]

I/O ports at 2438 [size=4]

I/O ports at 2410 [size=16]

[virtual] Expansion ROM at d4140000 [disabled] [size=128K]

Capabilities: [80] Power Management version 2

Kernel driver in use: ITE821x IDE

---------

I decided to upgrade to Xen 3.3 / 2.6.18 (gentoo r12).

But now the CONFIG_BLK_DEV_IT821X setting is not in .config and does not show up in menuconfig. It is hidden...except here:

---------

./drivers/ide/pci/Makefile:obj-$(CONFIG_BLK_DEV_IT821X) += it821x.o

./buildconfigs/linux-defconfig_xen_x86_32:CONFIG_BLK_DEV_IT821X=m

./buildconfigs/linux-defconfig_xen0_x86_64:# CONFIG_BLK_DEV_IT821X is not set

./buildconfigs/linux-defconfig_xen0_ia64:# CONFIG_BLK_DEV_IT821X is not set

./buildconfigs/linux-defconfig_xen_ia64:# CONFIG_BLK_DEV_IT821X is not set

./buildconfigs/linux-defconfig_xen0_x86_32:# CONFIG_BLK_DEV_IT821X is not set

./buildconfigs/linux-defconfig_xen_x86_64:CONFIG_BLK_DEV_IT821X=m

---------

So if I manually add the setting it is automatically removed. <sigh>

I can compile the driver to a .o:

---------

ring linux # make0 drivers/ide/pci/it821x.ko

  Using /usr/src/linux-2.6.18-xen-r12 as source for kernel

  GEN     /usr/src/linux-2.6.18-xen-r12/_dom0/Makefile

  CHK     include/linux/version.h

  CHK     include/linux/utsrelease.h

make[2]: `drivers/ide/pci/it821x.o' is up to date.

  MODPOST

---------

but it doesn't make a ".ko". <sigh>

I posted the .config that boots (but does not have this driver) at: http://www.doublepup.com/gentoo-xen0-2.6.18.config

- What do I do/set in my config to make this setting show up?

- How can I compile this module standalone as a loadable kernel module?

- Where should I go next?

TIA....
