Subject: [PATCH 10/14] kconfig: search for a config to base the local(mod|yes)config on
Date: Tue, 18 Aug 2009 22:56:44 -0400 [thread overview]
Message-ID: <20090819030038.750665213@goodmis.org> (raw)
In-Reply-To: 20090819025634.987354707@goodmis.org
[-- Attachment #1: 0010-kconfig-search-for-a-config-to-base-the-local-mod-ye.patch --]
[-- Type: text/plain, Size: 2524 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
Instead of using the .config in the local directory. This patch
changes streamline_config.pl to search various locations for a config.
Here's the list and order of search:
/proc/config.gz
/boot/vmlinuz-`uname -r`
vmlinux # local to the directory
/lib/modules/`uname -r`/kernel/kernel/configs.ko
kernel/configs.ko
kernel/configs.o
.config
Once it finds a file that contains a config (it checks if the binary
objects have configs first) it then uses it to create the .config
with minimum modules needed.
