Xen devel - Mar 2005 - Disappearing Kernel Options

I am trying to compile my own kernel to work with Xen and am having a
problem where menu options are disappearing on me. I have tried both
with a vanilla 2.6.10 kernel and with the 2.6.10-gentoo-r7 kernel. In
both kernels I cannot select my IDE chipset, as the options are not
presented to me - in the vanilla kernel I cannot even select ATA/EIDE at
all, as the menu has gone.

I have tried patching the sources by copying the contents of the
2.6.10-sparse directory and by using make mkpatches; patch -p1 and get
the same results both times.

I am using the files from xen-2.0-testing which I pulled with BK less
than 1 hour ago (approx 03:30 GMT)

Any help is appreciated!

Cheers

After a bit of playing around I have fixed this problem. I hadn''t
copied
the xen0_defconfig from arch/xen/configs/ to arch/xen/defconfig. Now
that I have I get those options back.

There is a bug, however. As long as the .config file has the PCI options
selected then the Bus Options option shows up under X86 Processor
Configuration, (not on the main menu as for usual kernel configures),
but if it is not, or the arch/xen/defconfig file is not in place then it
does not show at all.

FWIW, PCI support _is_ enabled by arch/xen/defconfig, so the cards show
up at that time.

Now all I need is to have access to the MTRR option (CONFIG_MTRR) that
is usually under Processor type and features ... :)
