One of the field was not initialized correctly, and it leads to the inability to turn off the privacy LED. Proposed fix merged as upstream commit https://github.com/intel/vision- drivers/commit/fc4981411e140674b016a3d7dc062434848f5311. [ Test Plan ] While different platforms may have different versions of CVS firmware, it's only known reproducible on a few still in-development OEM platforms. To verify: 0. verify CVS firmware version: ``` $ cd /sys/bus/i2c/devices/i2c-INTC* $ echo version | sudo tee cmd $ cat coredump ... CVS Firmware Ver: 132.39.66.9 (0x84.0x27.0x42.0x9) ... ``` 1. install linux-oem-6.11 >= 6.11.0-1019, 2. install intel-vision-dkms from -proposed pocket, 3. reboot to the same linux-oem-6.11 kernel, and browse to https://webcamtests.com to activate camera use. The privacy LED should be turned on while using, and off while camera stopped or browser terminated. 4. also covered platforms of previous generations with older CVS fw version: * Bolan14-DVT2-C3-202410-35910, cvs fw 132.24.50.50 (0x84, 0x18, 0x32, 0x32). * TRBL-DVT2-C1-202407-34214, cvs fw 1.19.0.0 (0x1, 0x13, 0x0, 0x0). * TRK4-DVT2-C4-202411-35941, cvs fw 132.24.50.50 (0x84, 0x18, 0x32, 0x32). [ Where problems could occur ] No. This is a field in the command data of a SET_HOST_IDENTIFIER command that is always sent in the vision-drivers >= 0~git202412180414.6b1462d8. When a order CVS fw receives such command, it replies a command error and does nothing. For a latter CVS fw, this field affects the privacy LED governing and should be fixed. [ Other Info ] The target kernel is linux-oem-6.11, and we're currently compiling visions-drivers/plucky into it. Nominate for Plucky and Questing. For Oracular, still under discussion. ========== original bug report ========== [Expects] 1. Launch camera apps like https://webcamtests.com in Firefox/Chrome 2. The privacy LED should be turned on [Actual] Privacy LED off all the time. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 1775 F.... pipewire ubuntu 1781 F.... wireplumber /dev/snd/seq: ubuntu 1775 F.... pipewire CasperMD5CheckMismatches: ./casper/initrd ./casper/vmlinuz ./casper/minimal.standard.live.hotfix.manifest ./casper/minimal.standard.live.hotfix.size ./casper/minimal.standard.live.size ./casper/minimal.manifest ./casper/minimal.standard.manifest ./casper/minimal.standard.size ./casper/minimal.hotfix.size ./casper/minimal.standard.live.hotfix.squashfs ./casper/minimal.standard.hotfix.squashfs ./casper/minimal.standard.hotfix.size ./casper/minimal.hotfix.squashfs ./casper/minimal.standard.live.manifest ./casper/minimal.size ./boot/grub/grub.cfg CasperMD5CheckResult: fail DistributionChannelDescriptor: # This is the distribution channel descriptor for Ubuntu 24.04 for Dell # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-noble-oem-24.04b-next-20250410-214 DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2025-04-10 (3 days ago) InstallationMedia: Ubuntu OEM 24.04.1 LTS "Noble Numbat" - Release amd64 (20250407) IwConfig: lo no wireless extensions. wlp0s20f3 no wireless extensions.
