X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=1b6776a5e7db5eec1a0e3b900b47096cb20e5aa3;hp=1b6776a5e7db5eec1a0e3b900b47096cb20e5aa3;p=carl9170fw.git kconfig: Add yes2modconfig and mod2yesconfig targets. Since kernel configs provided by syzbot are close to "make allyesconfig", it takes long time to rebuild. This is especially waste of time when we need to rebuild for many times (e.g. doing manual printk() inspection, bisect operations). We can save time if we can exclude modules which are irrelevant to each problem. But "make localmodconfig" cannot exclude modules which are built into vmlinux because /sbin/lsmod output is used as the source of modules. Therefore, this patch adds "make yes2modconfig" which converts from =y to =m if possible. After confirming that the interested problem is still reproducible, we can try "make localmodconfig" (and/or manually tune based on "Modules linked in:" line) in order to exclude modules which are irrelevant to the interested problem. While we are at it, this patch also adds "make mod2yesconfig" which converts from =m to =y in case someone wants to convert from =m to =y after "make localmodconfig".
