[Xen-devel] [PATCH]Allow different config file for xenlinux on same arch
Currently there is no generic configure file to compile xenlinux on ia64, since there''re several different system types like HP-ZX, DIG, etc. Current Makefile can''t meet this need and default one (xen0_defconfig_ia64) is only for HP-ZX type. Hence, this patch can append an additional param to configuration file name to differentiate system types when make. For example, we can use "make world XEN_SYSTYPE=dig" to compile, and if a config file named as xen0_defconfig_ia64dig exists under arch/xen/configs, it will be copied to override xen0_defconfig_ia64 before real compilation.. If no value for this option, it use default configure file for their archs. Configuration file is not attached here. If this approach is an agreed approach to solve such requirement, we will check in the config file in another mail.
