Hi, Xen is broken on all ARM configs on master branch.
On ARM, when you enable xen (CONFIG_PARAVIRT_XEN=y), this lead to a compilation problem: ******************************************************************************** [ 3509s] CC arch/arm/kernel/asm-offsets.s [ 3510s] In file included from /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/arch/arm/include/asm/io.h:31:0, [ 3510s] from /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/include/linux/scatterlist.h:10, [ 3510s] from /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/include/linux/dma-mapping.h:9, [ 3510s] from /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/arch/arm/kernel/asm-offsets.c:15: [ 3510s] /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/arch/arm/include/asm/dma-mapping.h: In function 'get_dma_ops': [ 3510s] /home/abuild/rpmbuild/BUILD/kernel-default-3.14.rc6/linux-3.14-rc6/include/xen/xen.h:29:38: error: dereferencing pointer to incomplete type [ 3510s] xen_start_info && xen_start_info->flags & SIF_INITDOMAIN) ******************************************************************************** Maybe because of this patch: http://lists.xen.org/archives/html/xen-devel/2013-07/msg01833.html Then, in "include/xen/interface/xen.h" file, "struct start_info" is not defined since XEN_HAVE_PV_GUEST_ENTRY is only defined for x86. I tried vanilla 3.14-rc6 and there is no problem. So, the problem is in openSUSE xen patches. Note that in arch/arm/{Kconfig,Makefile}, vanilla kernel uses CONFIG_XEN whereas openSUSE has CONFIG_PARAVIRT_XEN instead. I will send a patch to disable Xen on ARM for now until this problem is solved. Guillaume -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
