The UVC 1.5 standard defines 4 values for the PLF control: Off, 50Hz, 60Hz and Auto. But it does not clearly define if all the values must be implemented or not. Instead of just using the UVC version to determine what the PLF control can do, probe it. Reviewed-by:

Move the PLF mapping logic to its own mapping filter function. This commit does not introduce any new functionality to the logic, it is just a preparation patch. Reviewed-by:

Some advanced controls might not be completely implemented by vendors. If the controls are a enumeration, UVC does not gives a way to probe what is implemented and what is not. Let's create a new callback function where heuristics can be implemented to detect what is implemented and what not and update the control mapping accordingly. Reviewed-by:

The bandwidth fixup quirk doesn't know that SuperSpeed exists and has the same 8 service intervals per millisecond as High Speed, hence its calculations are wrong. Assume that all speeds from HS up use 8 intervals per millisecond. No further changes are needed, updated code has been confirmed to work with all speeds from FS to SS. Signed-off-by:

When the UVC device has a control that is readonly it doesn't set the SET_CUR flag. For example the privacy control has SET_CUR flag set in the defaults in the `uvc_ctrls` variable. Even if the device does not have it set, it's not cleared by uvc_ctrl_get_flags(). Originally written with assignment in commit 859086ae ("media: uvcvideo: Apply flags from device to actual properties"). But changed to |= in commit 0dc68cab ("media: uvcvideo: Prevent setting unavailable flags"). It would not clear the default flags. With this patch applied the correct flags are reported to user space. Tested with: ``` > v4l2-ctl --list-ctrls | grep privacy privacy 0x009a0910 (bool) : default=0 value=0 flags=read-only ``` Signed-off-by:

Struct uvc_frame and interval (u32*) are packaged together on streaming->formats on a single contiguous allocation. Right now they are allocated right after uvc_format, without taking into consideration their required alignment. This is working fine because both structures have a field with a pointer, but it will stop working when the sizeof() of any of those structs is not a multiple of the sizeof(void*). Enforce that alignment during the allocation. Signed-off-by:

The function uvc_video_clock_update() supports a single SOF overflow. Or in other words, the maximum difference between the first ant the last timestamp can be 4096 ticks or 4.096 seconds. This results in a maximum value for y2 of: 0x12FBECA00, that overflows 32bits. y2 = (u32)ktime_to_ns(ktime_sub(last->host_time, first->host_time)) + y1; Extend the size of y2 to u64 to support all its values.

In UVC 1.5 we get a single clock value per frame. With the current buffer size of 32, FPS slowers than 32 might roll-over twice. The current code cannot handle two roll-over and provide invalid timestamps. Revome all the samples from the circular buffer that are more than two rollovers old, so the algorithm always provides good timestamps. Note that we are removing values that are more than one second old, which means that there is enough distance between the two points that we use for the interpolation to provide good values.

Isolate all the changes related to the clock circular buffer to its own function, that way we can make changes easier to the buffer logic. Also simplify the lock, by removing the circular buffer clock handling from uvc_video_clock_decode(). And now that we are at it, unify the API of the clock functions. Tested-by:

With UVC 1.5 we get as little as one clock sample per frame. Which means that it takes 32 frames to move from the software timestamp to the hardware timestamp method. This results in abrupt changes in the timestamping after 32 frames (~1 second), resulting in noticeable artifacts when used for encoding. With this patch we modify the update algorithm to work with whatever amount of values are available. Tested-by:

We can think of the UVC hardware clock as a system with a coarse clock (the SOF) and a fine clock (the PTS). The coarse clock can be replaced with a clock on the same frequency, if the jitter of such clock is smaller than its sampling rate. That way we can save some of the precision of the fine clock. To probe this point we have run three experiments on the Logitech C922. On that experiment we run the camera at 33fps and we analyse the difference in msec between a frame and its predecessor. If we display the histogram of that value, a thinner histogram will mean a better meassurement.

Some SunplusIT cameras took a borderline interpretation of the UVC 1.5 standard, and fill the PTS and SCR fields with invalid data if the package does not contain data. "STC must be captured when the first video data of a video frame is put on the USB bus." Some SunplusIT devices send, e.g., buffer: 0xa7755c00 len 000012 header:0x8c stc 00000000 sof 0000 pts 00000000 buffer: 0xa7755c00 len 000012 header:0x8c stc 00000000 sof 0000 pts 00000000 buffer: 0xa7755c00 len 000668 header:0x8c stc 73779dba sof 070c pts 7376d37a While the UVC specification meant that the first two packets shouldn't have had the SCR bit set in the header. This borderline/buggy interpretation has been implemented in a variety of devices, from directly SunplusIT and from other OEMs that rebrand SunplusIT products. So quirking based on VID:PID will be problematic. All the affected modules have the following extension unit: VideoControl Interface Descriptor: guidExtensionCode {82066163-7050-ab49-b8cc-b3855e8d221d} But the vendor plans to use that GUID in the future and fix the bug, this means that we should use heuristic to figure out the broken packets.

The tail of the list lives at the position before the head. This is mathematically noted as: ``` (head-1) mod size. ``` Unfortunately C, does not have a modulus operator, but a remainder operator (%). The reminder operation has a different result than the modulus if (head -1) is a negative number and size is not a power of two. Adding size to (head-1) allows the code to run with any value of size. This does not change the current behaviour of the driver, as the size is always a power of two, but avoid tedious debugging if we ever change its size. Reviewed-by:

It was reported to me that the imx219 didn't work on one of our development kits partly because the access sequence is incorrect. The datasheet I could find [1] for this camera has the access sequence: Seq. No. Address (Hex) data 1 30EB 05 2 30EB 0C 3 300A FF 4 300B FF 5 30EB 05 6 30EB 09 but the driver swaps the first two elements. Laurent pointed out on IRC that the original code used the correct sequence for 1920x1080 but the current sequence for 3280x2464 and 1640x1232. During refactoring of the init sequence the current order was used for all formats. Switch to using the documented sequence.

The out of tree IPU6 driver comes with its own copy of the ipu-bridge code. It also comes bundled with standard v4l2 sensor drivers. Many of these have been mainlined and the rest is being mainlined but not all are upstream yet. The latest version of the out of tree code now will use the mainline kernel ipu-bridge version when build against new enough kernels. This however breaks support for (bundled) sensor drivers which do not (yet) have an entry in the mainline ipu-bridge code. Add the missing entries to the mainline ipu-bridge code to make the transition to having everything in mainline easier. The alternative HID for the OV13B10 and the OV08x40 entries both are for sensors already supported in mainline which were missing. The downside of adding these HIDs is that this will cause the IPU3 / IPU6 drivers to delay registering there /dev/video# nodes until a sensor driver has bound, which for the non mainline drivers may never happen. This is not really an issue because almost all IPU designs only have front (user) facing sensors and all the added HIDs are for the main RGB (not IR) sensor. So if the sensor driver is missing then the user can already not use the camera and adding these HIDs does not really change that. Signed-off-by:

The privacy status is maintained by privacy_ctrl, on which all of the privacy status changes will go through, so there is no point in maintaining one more element any more. Reported-by:

Prior to the ongoing command privacy is on, it would return -1 to indicate the current privacy status, and the ongoing command would be well executed by firmware as well, so this is not error. This patch changes its behavior to notify privacy on directly by V4L2 privacy control instead of reporting error. Fixes: 29006e19 ("media: pci: intel: ivsc: Add CSI submodule") Cc: stable@vger.kernel.org # for 6.6 and later Reported-by:

There're possibilities that privacy status change notification happens in the middle of the ongoing mei command which already takes the command lock, but v4l2_ctrl_s_ctrl() would also need the same lock prior to this patch, so this may results in circular locking problem. This patch adds one dedicated lock for v4l2 control handler to avoid described issue.

Replace the older style one-element array with a flexible array member. There does not seem to be any allocation for these structs in the code, so no more code changes are required.
