This is an experimental build system for media drivers. All files on this tree are covered by GPLv2, as stated at COPYING file.

Usage:

Just call the build utility: $ ./build

Then, install the drivers as root, with:

make install

In order to test, unload old drivers with:

make rmmod

Then modprobe the driver you want to test. For example, to load driver 'foo':

modprobe foo

If you're developing a new driver or patch, it is better to use: $ ./build --main-git

Then, install the drivers as root, with:

make install

In order to test, unload old drivers with:

make rmmod

Then modprobe the driver you want to test. For example:

modprobe bttv

In this case, in order to modify something, you should edit the file at the media/ subdir.

For example, a typical procedure to develop a new patch would be:

~/media_build $ cd media
~/media $ gedit drivers/media/video/foo.c
~/media $ make -C ../v4l
~/media $ make -C .. rmmod
~/media $ modprobe foo
(some procedure to test the "foo" driver)
~/media $ git diff >/tmp/my_changes.patch
(email /tmp/my_changes.patch inlined to linux-media@vger.kernel.org)
