Revert "media: cx231xx: add USB ID 2040:8360 for Hauppauge WinTV-HVR-935"

2026-03-26T21:27:24Z

This reverts commit bb2a3912549d3b5cef5ed27200402fe8f6fb0694. The USB ID 2040:8360 was reported as a new revision of Hauppauge HVR-935 and requested to be added to the cx231xx driver. The issue is current generation of Hauppauge 9x5 devices including 935, 955, and 975 have moved to em2828x usb bridge. Support for the em2828x usb bridge and USB ID's for the new devices has been submitted. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: uvcvideo: Fix bug in error path of uvc_alloc_urb_buffers

2026-03-26T12:14:07Z

Recent cleanup introduced a bug in the error path of uvc_alloc_urb_buffers(). If there is not enough memory for the allocation the following error will be triggered: [ 739.196672] UBSAN: shift-out-of-bounds in mm/page_alloc.c:1403:22 [ 739.196710] shift exponent 52 is too large for 32-bit type 'int' Resulting in: [ 740.464422] BUG: unable to handle page fault for address: fffffac1c0800000 The reason for the bug is that usb_free_noncoherent is called with an invalid size (0) instead of the actual size of the urb. This patch takes care of that.

media: em28xx: Add Hauppauge em2828X based 9x5 revisions

2026-03-25T17:27:25Z

The Hauppauge HVR-935, HVR-955, and HVR-975 have moved from cx231xx bridge to em2828x bridge. The following USB device id's are new: 2040:0360 - HVR-935 ISOC transport 2040:8360 - HVR-935 Bulk transport 2040:0366 - HVR-955 ISOC transport 2040:8366 - HVR-955 Bulk transport 2040:036a - HVR-975 ISOC transport 2040:836a - HVR-975 Bulk transport The devices all now utilize si2177 tuner. Capabilities are: - Digital TV - Composite video input - S-Video input - Analog stereo input HVR-935 has DVB-C/T/T2 demod (si2168). HVR-955 has ATSC/QAM demod (lgdt3306a). HVR-975 has both ATSC/QAM and DVB-C/T/T2 demods. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil [hverkuil: a few minor checkpatch fixes]

media: em28xx: driver supports two frontends, but not i2c clients

2026-03-25T17:27:25Z

Fix em28xx driver to accommodate a device with two i2c client demods. The em28xx driver already had a multi frontend aware device struct, with two fe, just not two i2c client demods. Since Hauppauge HVR975 has transitioned from cx231xx to em2828X, this is required for full functionality of the devices. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: au0828: Fix green screen in analog

2026-03-25T17:27:25Z

When the driver was converted to VB2 the original function to fix green frame detection was removed and a default vb2 dqbuf function was used instead. This vb2 dqbuf function leads to green frames not being detected and correupting stream captures. The vidioc_dqbuf function checks the greenscreen flag, and, if set resets the stream to discard the green frame and decode a real frame. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: em28xx: Add Hauppauge USB Live2

2026-03-25T17:27:25Z

New revision of Hauppauge USB Live2 switches from cx231xx usb bridge to Empia em2828X bridge. Inputs for the USB Live2 remain the same: - Composite video - S-Video - Analog stereo audio Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil

media: em28xx: Add support for Empia em2828X bridge

2026-03-25T17:27:25Z

The empia em2828X usb bridge contains previous functionality, but also contains an embedded video decoder. The implemented capabilities include composite and s-video inputs, as well as analog TV. Analog TV is expected in CVBS format, it must be demodulated already. Media controller decoder entity is included so pipeline verification passes and graph is properly constructed. Analog TV bits based off cx231xx driver. Signed-off-by: Bradford Love Signed-off-by: Hans Verkuil [hverkuil: fix a few minor checkpatch issues]

media: uvcvideo: Add support for P010 pixel format

2026-03-25T08:40:28Z

Add support for the P010 (10-bit Y/UV 4:2:0) pixel format to the uvcvideo driver. This format is exposed by USB capture devices such as the Magewell USB Capture HDMI 4K Pro when capturing HDR10 content. P010 stores 10-bit Y and interleaved UV samples in 16-bit little-endian words, with data in the upper 10 bits and zeros in the lower 6 bits. This requires 2 bytes per sample, so bytesperline is wWidth * 2. V4L2_PIX_FMT_P010 was added to the V4L2 core in commit 5374d8fb75f3 ("media: Add P010 video format"). Based on the community DKMS patch from awawa-dev/P010_for_V4L2.
