Hello, One tought or two between wake-up and leaving for work :-) trunk/build_dir/toolchain-i386_gcc-linaro_uClibc-0.9.32/linux-2.6.37 is kernel builddir. So, if it works from here, there's no reason it finaly doesn't. One tought: in "make menuconfig", you will setup the Openwrt's package/features list. If you have one package marked "M", that means it'll be build as separate package (*.opkg). If marked with "y", it'll be integrated within FS image. For you kernel module xen-pcifront, you have to make sure that: - it's marked in trunk/.config - it's marked in kernel config file You can check after compliation: ls -l build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/ total 12 drwxr-xr-x 2 jbfavre jbfavre 4096 Mar 4 01:09 CONTROL drwxr-xr-x 3 jbfavre jbfavre 4096 Mar 4 01:09 etc drwxr-xr-x 3 jbfavre jbfavre 4096 Mar 4 01:09 lib jbfavre@xps-103:~/openwrt/trunk$ ls -l build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/lib/module= s/2.6.37/platform-pci.ko -rw-r--r-- 1 jbfavre jbfavre 4936 Mar 4 01:09 build_dir/linux-x86_xen_domu/packages/ipkg-x86/kmod-xen-pcidev/lib/module= s/2.6.37/platform-pci.ko So, not sure you patch is mandatory, is it ?
