Hi Christian,
Your recent patch enables uncompressed kernels, but selecting that option (CONFIG_KERNEL_UNCOMPRESSED) fails on x86_86:
commit 69f0554ec261fd686ac7fa1c598cc9eb27b83a80 Author: Christian Ruppert <christian.ruppert@abilis.com> Date: Tue Nov 12 15:11:43 2013 -0800
init/Kconfig: add option to disable kernel compression
That's how it fails:
LD init/built-in.o KSYM .tmp_kallsyms1.o KSYM .tmp_kallsyms2.o LD vmlinux SORTEX vmlinux SYSMAP System.map VOFFSET arch/x86/boot/voffset.h make[4]: *** No rule to make target `arch/x86/boot/compressed/vmlinux.bin.', needed by `arch/x86/boot/compressed/piggy.S'. Stop. make[3]: *** [arch/x86/boot/compressed/vmlinux] Error 2 make[2]: *** [bzImage] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2
arch/x86/boot/compressed/Makefile has no provision for uncompressed files. There is no definition for suffix-$(CONFIG_KERNEL_UNCOMPRESSED) so $(suffix-y) evaluates to an empty string and there is no rule to make vmlinuz.bin.$(suffix-y)
I think the patch should be either reverted or fixed as soon as possible.
Any suggestions for uncompressed suffix? I'd go with "copy". Then the "compression" could be a symlink. Alternatively, the "." could be included in other suffixes, the uncompressed suffix would be empty and the compression would be an empty statement.
