[media] dvbdev: Add RF connector if needed

2016-01-11T14:19:25Z

Several pure digital TV devices have a frontend with the tuner integrated on it. Add the RF connector when dvb_create_media_graph() is called on such devices. Tested with siano and dvb_usb_mxl111sf drivers. Signed-off-by: Mauro Carvalho Chehab

[media] usb: check media device errors

2016-01-11T14:19:15Z

There are now two new warnings: drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_media_device_register': drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:433:2: warning: ignoring return value of '__media_device_register', declared with attribute warn_unused_result [-Wunused-result] media_device_register(adap->dvb_adap.mdev); ^ drivers/media/usb/dvb-usb/dvb-usb-dvb.c: In function 'dvb_usb_media_device_register': drivers/media/usb/dvb-usb/dvb-usb-dvb.c:128:2: warning: ignoring return value of '__media_device_register', declared with attribute warn_unused_result [-Wunused-result] media_device_register(adap->dvb_adap.mdev); ^ Those are because the drivers are not properly checking if the media device init and register were succeeded. Fix it. Signed-off-by: Mauro Carvalho Chehab

[media] media-device: split media initialization and registration

2016-01-11T14:19:15Z

The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().

[media] dvb core: must check dvb_create_media_graph()

2016-01-11T14:18:59Z

If media controller is enabled and mdev is filled, it should ensure that the media graph will be properly initialized. Enforce that. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] use https://linuxtv.org for LinuxTV URLs

2015-12-04T12:38:59Z

While https was always supported on linuxtv.org, only in Dec 3 2015 the website is using valid certificates. As we're planning to drop pure http support on some future, change all references at the media subsystem to point to the https URL instead. Signed-off-by: Mauro Carvalho Chehab

[media] Technisat SkyStar USB HD,(DVB-S/S2) too much URBs for arm devices

2015-08-11T17:43:23Z

Using 8 URBs results in a consecutive buffer allocation of too much memory for some arm devices. As we use isochronuous transfers the number of URBs can be reduced without risking data-loss. Signed-off-by: Christian Loepke Signed-off-by: Mauro Carvalho Chehab

[media] pctv452e: Replace memset with eth_zero_addr

2015-08-11T15:57:01Z

Use eth_zero_addr to assign the zero address to the given address array instead of memset when second argument is address of zero. Note that the 6 in the third argument of memset appears to represent an ethernet address size (ETH_ALEN). The Coccinelle semantic patch that makes this change is as follows: // @eth_zero_addr@ expression e; @@ -memset(e,0x00,6); +eth_zero_addr(e); // Signed-off-by: Vaishali Thakkar Signed-off-by: Mauro Carvalho Chehab

[media] dvb: Get rid of typedev usage for enums

2015-06-09T20:47:35Z

The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

[media] dib0700: avoid the risk of forgetting to add the adapter's size

2015-05-14T22:31:34Z

For every frontend entry, we need to add the adapter's size. There are already two patches fixing it. So, it doesn't seem trivial to keep it there at the right place. Also, currently, the indentation is wrong on all places. So, it seems that keeping it right is not too trivial. Better to use a macro that would do it for us, at least while this is not converted to dvb-usb-v2. Compile-tested only. Signed-off-by: Mauro Carvalho Chehab

[media] media: Fix regression in some more dib0700 based devices

2015-05-13T21:18:39Z

Fix an oops during device initialization by correctly setting size_of_priv instead of leaving it 0. The regression was introduced by 8abe4a0a3f6d4217b16a ("[media] dib7000: export just one symbol") and only fixed for one type of dib0700 based devices in 9e334c75642b6e5bfb95 ("[media] Fix regression in some dib0700 based devices").
