The old debug field is renamed to dev_debug to ensure that existing drivers (including out-of-tree drivers) that try to use the old name will no longer compile. A comment has also been added that makes it explicit that drivers shouldn't use this field. Additional bits have been added to the debug flag to be more fine-grained when debugging, especially when dealing with streaming ioctls and read, write and poll. You want to enable those explicitly to prevent flooding the log when streaming unless you actually want to do that. Signed-off-by:

The debug field in struct video_device is for internal use only and drivers should mix that with their own debug module options. It is handled by the V4L2 core and users can set it using /sys/class/video4linux/<devX>/debug. It has been deprecated for some time now, so it is time to remove it completely from the drivers.

[media] solo6x10: just pass frame motion flag from hardware, drop additional handling as complicated and unstable Dropping code (introduced in 316d9e84) which intends to make raising of motion events more "smooth"(?). It made motion event never appear in my installation. That code is complicated, so I couldn't figure out quickly how to fix it, so dropping it seems better to me. Another justification is that anyway application would implement "motion signal stabilization" if required, it is not necessarily kernel driver's job. Signed-off-by:

The video output functionality never worked for this driver. Now remove the creation of the output video nodes as well to prevent users from thinking that video output is available, when it isn't. To correctly implement this the video output should use vb2 as well, and that requires rewriting the output DMA setup. But without hardware to test I am not able to do that. Signed-off-by:

The btcx-risc module is no longer used by other drivers except for bttv. So move it from common to bt8xx and make it part of the bttv driver instead of as a separate module. This module should never have been a common module since most of the code has always been bttv specific. Signed-off-by:

Remove this comment block, it's unused. This removes the btcx_riscmem reference as well, since that will no longer be available to other drivers except bttv. Signed-off-by:

Regardless of a number of inputs, we should always enable virtual RPF when BRU is used. This allows the case when there's only one input to BRU, and a size of the input is smaller than a size of an output of BRU. Signed-off-by:

The Magewell XI100DUSB-HDMI[1] video capture device reports the pixel format "e436eb7d-524f-11ce-9f53-0020af0ba770". This is its GUID for BGR 8:8:8. The UVC 1.5 spec[2] only defines GUIDs for YUY2, NV12, M420 and I420. This seems to be an extension documented in the Microsoft Windows Media Format SDK[3] - or at least the Media Format SDK was the only hit that Google gave when searching for the GUID. This Media Format SDK defines this GUID as corresponding to `MEDIASUBTYPE_RGB24`. Note though, the XI100DUSB outputs BGR e.g. byte-reversed. I don't know if its the capture device in error or Microsoft mean BGR when they say RGB.

If an entity can't be started when starting a pipeline we need to clean up by stopping all entities that have been successfully started. Otherwise the hardware and software states won't match, potentially leading to crashes (for instance due to the CSI2 receiver receiving interrupts with a NULL pipeline pointer). Signed-off-by:

Compute the pipeline frame number from the frame number sent by the sensor instead of incrementing the frame number in software. This improves dropped frames detection. Signed-off-by:
-
Laurent Pinchart authored
Frame number propagation tries to increase the robustness of the frame number counter by using sources less likely to be missed than the end of frame interrupts, such as hardware frame counters or start of frame interrupts. Increasing the frame number in the IPIPE ISIF and resizer end of frame interrupt handlers is pointless as it doesn't bring any improvement. Don't do it. Signed-off-by:

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger: "kernel: Provide READ_ONCE and ASSIGN_ONCE As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com ACCESS_ONCE might fail with specific compilers for non-scalar accesses. Here is a set of patches to tackle that problem. The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure is larger than the machine word size memcpy is used and a warning is emitted. The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar types. This does not yet contain a patch that forces ACCESS_ONCE to work only on scalar types. This is targetted for the next merge window as Linux next already contains new offenders regarding ACCESS_ONCE vs. non-scalar types" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/borntraeger/linux: s390/kvm: REPLACE barrier fixup with READ_ONCE arm/spinlock: Replace ACCESS_ONCE with READ_ONCE arm64/spinlock: Replace ACCESS_ONCE READ_ONCE mips/gup: Replace ACCESS_ONCE with READ_ONCE x86/gup: Replace ACCESS_ONCE with READ_ONCE x86/spinlock: Replace ACCESS_ONCE with READ_ONCE mm: replace ACCESS_ONCE with READ_ONCE or barriers kernel: Provide READ_ONCE and ASSIGN_ONCE
