From 2c8fe1f14240d75f2002e16b2b69c5c2d27ed41c Mon Sep 17 00:00:00 2001 From: Oliver Collyer Date: Fri, 26 Dec 2025 06:57:18 +0000 Subject: media: uvcvideo: Add support for P010 pixel format 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.
