[PATCH RFC] [media] Postpone the addition of MEDIA_IOC_G_TOPOLOGY
by Mauro Carvalho Chehab 28 Dec '15

28 Dec '15

There are a few discussions left with regards to this ioctl: 1) the name of the new structs will contain _v2_ on it? 2) what's the best alternative to avoid compat32 issues? Due to that, let's postpone the addition of this new ioctl to the next Kernel version, to give people more time to discuss it.

[PATCH] dvbdev: remove two dead functions if !CONFIG_MEDIA_CONTROLLER_DVB

Those functions are used only if CONFIG_MEDIA_CONTROLLER_DVB.

[PATCH] [media] usb: check media device errors

[PATCH] [media] call media_device_init() before registering the V4L2 device
by Mauro Carvalho Chehab 28 Dec '15

28 Dec '15

Currently, v4l2_device_register() doesn't use the media_device struct. So, calling media_device_init() could be called either before or after v4l2_device_register(). Yet, it is a good practice to initialize everything before calling the register functions. Also, the other drivers call media_device_init() before registering the V4L2 device. So, move the call for media_device_init() to happen earlier on exynos4-is and s3c-camif. This is just a cleanup patch.

[PATCH v8.4 00/83] Media MC patches
by Mauro Carvalho Chehab 11 Dec '15

11 Dec '15

As requested by Sakari and Hans, I'm re-sending the entire 83 patch series that were already sent to the media ML. NOTE: as agreed on IRC, after getting the ack for those patches, eventually adding newer fixups where needed, we should add this to the media-controller topic branch of our devel tree. Before merging this on the "master" branch, we'll: 1) add a patch series that Sakari is working to allow not using the entity_id for the graph traversal; 2) add a patch converting MC next gen to use a single range, as agreed on IRC; 3) add a patch increasing the maximum number of objects, in order for the graph traversal to work with DVB drivers; 4) get ALSA maintainer's acks for the ALSA changes (on this series and on Shuah's series); 5) add Shuah ALSA patches. I'll do the above work after getting the acks for the patches already sent.
