linux-toradex.git/kernel/configs, branch v3.19-rc6 Linux kernel for Apalis and Colibri modules x86: Add "make tinyconfig" to configure the tiniest possible kernel 2014-08-08T23:30:24+00:00 Josh Triplett josh@joshtriplett.org 2014-08-08T23:25:47+00:00 0da1d4a0b9516adb2acc4841e9f6da6618f47f4e Since commit 5d2acfc7b974bbd3858b4dd3f2cdc6362dd8843a ("kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1, "make allnoconfig" disables every possible config option. However, a few configuration options (CC_OPTIMIZE_FOR_SIZE, OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few choices exist (compression, highmem, allocator) for which a non-default option produces a smaller kernel. Add a "tinyconfig" option, which starts from allnoconfig and then sets these options to configure the tiniest possible kernel. This provides a better baseline for embedded systems or efforts to reduce kernel size. Signed-off-by: Josh Triplett <josh@joshtriplett.org>
