| * [media] uvcvideo: add support for VIDIOC_QUERY_EXT_CTRLHans Verkuil2015-04-101-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the new VIDIOC_QUERY_EXT_CTRL ioctl. Since uvc doesn't use the control framework, support for this ioctl isn't automatic. This is makes v4l2-compliance happy as well.

| * [media] uvcvideo: fix cropcap v4l2-compliance failureHans Verkuil2015-04-101-12/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v4l2-compliance tool expects that if VIDIOC_CROPCAP is defined, then VIDIOC_G_SELECTION for TGT_CROP_BOUNDS/DEFAULT is also defined (or COMPOSE in the case of an output device). In fact, all that a driver has to do to implement cropcap is to support those two targets since the v4l2 core will implement cropcap and fill in the pixelaspect to 1/1 by default. Implementing cropcap is only needed if the pixelaspect isn't square. So implement g_selection instead of cropcap in uvc to fix the v4l2-compliance failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | videobuf2 has long been subject to AB-BA style deadlocks due to the queue lock and mmap_sem being taken in different orders for the mmap and get_unmapped_area operations. The problem has been fixed by making those two operations callable without taking the queue lock, using an mmap_lock internal to videobuf2. The uvcvideo driver still calls the mmap and get_unmapped_area operations with the queue lock held, resulting in a potential deadlock. As the operations can now be called without locking the queue, fix it.

| * [media] fixp-arith: replace sin/cos table by a better precision oneMauro Carvalho Chehab2015-03-021-8/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cos table used at fixp-arith.h has only 8 bits of precision. That causes problems if it is reused on other drivers. As some media drivers require a higher precision sin/cos implementation, replace the current implementation by one that will provide 32 bits precision. The values generated by the new implementation matches the 32 bit precision of glibc's sin for an angle measured in integer degrees. It also provides support for fractional angles via linear interpolation. On experimental calculus, when used a table with a 0.001 degree angle, the maximum error for sin is 0.000038, which is likely good enough for practical purposes. There are some logic there that seems to be specific to the usage inside ff-memless.c. Move those logic to there, as they're not needed elsewhere.

| * [media] cx231xx: drop condition with no effectNicholas Mc Guire2015-03-021-10/+3Star
| | | | | | | | | | | | | | | | | | | | The if and the else code are identical - so the condition has no effect on the effective code. This patch removes the condition and the duplicated code.

| * [media] use a function for DVB media controller registerMauro Carvalho Chehab2015-03-023-5/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is really a simple function, but using it avoids to have if's inside the drivers. Also, the kABI becomes a little more clearer. This shouldn't generate any overhead, and the type check will happen when compiling with MC DVB enabled. So, let's do it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| * [media] dvbdev: use adapter arg for dvb_create_media_graph()Mauro Carvalho Chehab2015-03-023-5/+4Star
| | | | | | | | | | | | | | | | | | | | Instead of using media_dev argument for dvb_create_media_graph(), use the adapter. That allows to create a stub for this function, if compiled without DVB support, avoiding to add extra if's at the drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | | | | | | | | | | | | | | Instead of assuming just one adapter, change the code to store one media controller per adapter. This works fine for dvb-usb, as, on all drivers here, it is not possible to write a media graph that would mix resources between the two different adapters.

| * [media] siano: register media controller earlierMauro Carvalho Chehab2015-02-261-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | We need to initialize the media controller earlier, as the core will call the smsdvb hotplug during register time. Ok, this is an async operation, so, when the module is not loaded, the media controller works. However, if the module is already loaded, nothing will be registered at the media controller, as it will load too late. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
