kconfig: add xenconfig defconfig helper

2015-06-16T10:04:29Z

This lets you build a kernel which can support xen dom0 or xen guests on i386, x86-64 and arm64 by just using: make xenconfig You can start from an allnoconfig and then switch to xenconfig. This also splits out the options which are available currently to be built with x86 and 'make ARCH=arm64' under a shared config. Technically xen supports a dom0 kernel and also a guest kernel configuration but upon review with the xen team since we don't have many dom0 options its best to just combine these two into one. A few generic notes: we enable both of these: CONFIG_INET=y CONFIG_BINFMT_ELF=y although technically not required given you likely will end up with a pretty useless system otherwise. A few architectural differences worth noting: $ make allnoconfig; make xenconfig > /dev/null ; \ grep XEN .config > 64-bit-config $ make ARCH=i386 allnoconfig; make ARCH=i386 xenconfig > /dev/null; \ grep XEN .config > 32-bit-config $ make ARCH=arm64 allnoconfig; make ARCH=arm64 xenconfig > /dev/null; \ grep XEN .config > arm64-config Since the options are already split up with a generic config and architecture specific configs you anything on the x86 configs are known to only work right now on x86. For instance arm64 doesn't support MEMORY_HOTPLUG yet as such although we try to enabe it generically arm64 doesn't have it yet, so we leave the xen specific kconfig option XEN_BALLOON_MEMORY_HOTPLUG on x86's config file to set expecations correctly. Then on x86 we have differences between i386 and x86-64. The difference between 64-bit-config and 32-bit-config is you don't get XEN_MCE_LOG as this is only supported on 64-bit. You also do not get on i386 XEN_BALLOON_MEMORY_HOTPLUG, there does not seem to be any technical reasons to not allow this but I gave up after a few attempts.

kbuild: add generic mergeconfig target, %.config

2015-03-24T15:48:44Z

"scripts/kconfig/merge_config.sh && make oldconfig" works well enough for merging local config fragments, but Kbuild currently has the entry points only for "kvmconfig" and "tinyconfig". This commit provides the generic target for mergeconfig, so we can manage our own config fragments easily: put "foo.config" in arch/$(SRCARCH)/configs/ or kernel/configs/, and then run "make foo.config". Now "make kvmconfig" is just a shorthand of "make kvm_guest.config". Likewise, "make tinyconfig" is equivalent to "make allnoconfig tiny.config".

kbuild: mergeconfig: remove redundant $(objtree)

2015-03-24T15:48:44Z

Kbuild always runs in $(objtree). Actually, $(objtree) is always set to "." by the top-level Makefile. We can omit "-O $(objtree)" and "$(objtree)/". Signed-off-by: Masahiro Yamada Reviewed-by: Josh Triplett Reviewed-by: Darren Hart Signed-off-by: Michal Marek
