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: http://www.mail-archive.com/linuxtv-commits@xxxxxxxxxxx/msg13388.html regards Antti -- http://palosaari.fi/ -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
