* [media] omap3isp: Prevent pipelines that contain a crashed entity from startingLaurent Pinchart2012-05-08
| | | | | | | | | | | | | | | | | | | | | The OMAP3 ISP preview engine will violate the L4 bus protocol if we try to write some of its internal registers after it failed to stop properly. This generates an external abort on non-linefetch fault, triggering a fatal kernel oops. We can't always prevent preview engine stop failures (they can for instance be caused by a sensor crash), but we can improve the system reliability by refusing to start streaming on a pipeline that contains the preview engine if it failed to stop. The driver will then eventually reset the ISP (when all applications will have closed their file handles related to OMAP3 ISP device nodes), making the ISP usable again.

* [media] pvrusb2: For querystd, start with list of hardware-supported standardsMike Isely2012-05-07
| | | | | | | | | | | | | | The V4L querystd implementation appears to want to narrow down the list of available standards by starting with a hardware-supported list and then attempting to detect which among those are actually available. Prior to this change in the pvrusb2 driver we started with all possible standards. With this change in place we instead narrow to just the standards that we know the hardware can actually support. For example, this removes the ATSC standards from the list if we aren't dealing with a hybrid device...

* [media] pvrusb2: Base available video standards on what hardware supportsMike Isely2012-05-07
| | | | | | | | | | | | | With the transition to ioctl2, the pvrusb2 driver's own standards enumeration is no longer used. Instead a generic algorithm internal to v4l is used (which is a great idea - since the pvrusb2 implementation itself was generic anyway). This change ensures that the v4l algorithm works with the correct set of hardware supported standards. This resolves a FIXME left behind from the videodev_ioctl2 transition.

* [media] pvrusb2: Stop statically initializing reserved struct fields to zeroMike Isely2012-05-07
| | | | | | | | | | | | | | In any statically initialized data structure, the compiler is going to zero any part which is not already explicitly initialized. While we can take that knowledge overboard and simply avoid initializing anything that needs to be zero, it's at least a good idea not to bother zeroing parts that we don't otherwise care about - like "reserved" fields which may change in the future. Avoiding initialization of those fields now also avoids possible conflict down the road. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
