Hi,
Well, I'm trying to compile a custom xen0 kernel now but having some
problems.
I downloaded the xen source then did a "make world" and ran install.sh
Then I went into the linux-2.6.11-xen0 directory and did "make ARCH=xen
menuconfig" and setup the kernel the way I needed it and then did a "make".
It chugs along like normal for awhile until it pukes on this:
drivers/xen/balloon/balloon.c: In function `balloon_process':
drivers/xen/balloon/balloon.c:218: error: `phys_to_machine_mapping'
undeclared (first use in this function)
drivers/xen/balloon/balloon.c:218: error: (Each undeclared identifier is
reported only once
drivers/xen/balloon/balloon.c:218: error: for each function it appears in.)
drivers/xen/balloon/balloon.c:218: error: `INVALID_P2M_ENTRY' undeclared
(first use in this function)
drivers/xen/balloon/balloon.c:261: warning: implicit declaration of function
`scrub_pages'
drivers/xen/balloon/balloon.c:283: warning: implicit declaration of function
`mfn_to_pfn'
make[3]: *** [drivers/xen/balloon/balloon.o] Error 1
make[2]: *** [drivers/xen/balloon] Error 2
make[1]: *** [drivers/xen] Error 2
make: *** [drivers] Error 2
Any ideas on how to get around this?
Thanks.
