[Xen-users] problems about compiling the unmodified drivers in xen-3.4.0

[不知道 <vmkernelli@xxxxxxxxxxxx>]

Hi, all:
     I want to check the function of the balloon driver in HVM guest. But I met a lot of problems when I compiling the balloon driver. I have read the related questions in the mailing-list, but still can not solve this problem.

    According to the README file in xen-3.4.0/unmodified_drivers, I did the following work.

    step 1: ./mkbuildtree (It's ok)
    step 2: make -C xen-3.4.0/linux-2.6.18-xen.hg M=$PWD modules
  
    After a lot of redefined warning messages, I get the error message
"In file included from include/asm/mach-xen/asm/pgtable.h:259,

                 from include/linux/mm.h:39,
                 from xen-3.4.0/unmodified_drivers/linux-2.6/balloon/balloon.c:40:
include/asm/mach-xen/asm/pgtable-3level.h:178: error: expected ‘)’ before numeric constant"

How can I solve this problem? thanks!

BTW: I want to the balloon driver can work in HVM guest with higher kernel version.
for example: the HVM guest's kernel is 2.6.29. when I use the mkbuildtree script, the file path in this script doesn't exist in 2.6.29 kernel. For example, the 2.6.18-xen.hg kernel has the "drivers/xen/core" directory  but the 2.6.29 kernel hasn't, It has only "drivers/xen" directory. So How can I compile a balloon driver for higher kernel HVM guest?

any suggestion are welcome. thanks again!
