Bug description:
[SRU Justification]
[ Impact ]
With CVS firmware >= version 132.39.66.9(0x84.0x27.0x42.0x9),
SET_HOST_IDENTIFIER was added. 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, won't fix per offline discussion with @anthonywong.
========== 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.
