I have a couple of patches to my local media_build repo, which do these:
- a new option "--as-is" to the build script. It basically suppresses any git
pull/rebase to both media_build and the ./media subdirectory (if used in combination with
--main-git). In combination to --main-git, you are left on your own and be wholy
responsible about what is inside ./media - I use that to check Antti's work (which is on
a branch), and also since I have some interrim patches to media_build itself, I would
prefer I can tell it not to pull/merge .
- a small change to v4l/Makefile , to install under /lib/modules/$(KERNELRELEASE)/updates/... - recent fedora seems to
have a modprobe preference to load from "../updates/..." (or at least, that's the case of having installed
compat-wireless at some stage - one might want to steal some code from that?), when more than one kernel module of the
same name exists. This is so as not to trash distro-shipped modules (and also if one cleans out
".../updates/..." and runs "depmod -a", one is back to distro as shipped behavior). Also trashing
distro-shipped modules have the side-effect of making drpm not to work and whole kernel packages are downloaded in the
next "yum upgrade".
I also have a suggestion to make:
- How http://linux/linuxtv.org/downloads/drivers/linux-media-LATEST.tar.bz2
is generated, probably should be documented. Over the weekend I was playing
with one with timestamp Jul 7, and it is quite broken with firstly header files
not in the right place (linux/v4l2-common.h instead of media/v4l2-common.h),
and also the following:
media_build/v4l/../linux/include/media/v4l2-dev.h:127:2: error: unknown type
name 'v4l2_std_id'
media_build/v4l/../linux/include/media/v4l2-dev.h:128:2: error: unknown type
name 'v4l2_std_id'
media_build/v4l/../linux/include/media/v4l2-dev.h:135:32: error:
'BASE_VIDIOC_PRIVATE' undeclared here (not in a function)
I see that the Jul 16 version has both of these issues fixed... but I am not
against having a look myself if it is urgent enough for me (considered that it
was broken for 9 days).
- a few of the firmware files are newer/different than distro-shipped... I am
less bothered by it trashing distro-shipped packaged files as the
linux-firmware package is rarely upgraded. But maybe one can try pushing some
of that upstream?
The last one, something for Antti to figure out:
- I found that that part of backports/api_version.patch, which changes
LINUX_VERSION_CODE to V4L2_VERSION in drivers/media/video/v4l2-ioctl.c, is
relocated from line 930-ish in
http://linux/linuxtv.org/downloads/drivers/linux-media-LATEST.tar.bz2 to
line 590-ish in Antti's dvb_core branch. So there are commits which are in
linux-media-LATEST.tar.bz2 and not in Antti's branch or vice versa. (so that's
any reason who one wants to know how linux-media-LATEST.tar.bz2 is made).
I used Linus 3.5 development tree as a base and rebased it continuously
to latest rc. Current media_build.git seems to download some older
files. I could guess it is tar'ed from Kernel 3.4 /drivers/media/
Patch which likely breaks backports/api_version.patch is that:
