ALS function lost after suspend/resume
Status in OEM Priority Project:
Status in iio-sensor-proxy package in Ubuntu:
Status in iio-sensor-proxy source package in Focal:
* Some Dell machine support ALS (ambient light sensor) will lost function after suspend/resume
It originally only report iio-buffer-als by udev rule, but the buffer no longer update after
suspend/resume, the issue can be eliminated by polling in_illuminance_raw node.
* Boot a machine with ALS support, and check it by
$ cat /sys/bus/iio/devices/iio:device*/name => see if it contains name als
* do suspend/stress by
$ sudo -s
# for i in `seq 20`; do sleep 5; rtcwake -m mem -s 10; done
* run monitor-sensor and cover your hand on the light sensor
* if the als function lost, there should be no update of the ambient light sensor anymore
[Where problems could occur]
* The change add in_illuminance_raw check and add iio-poll-als to
IIO_SENSOR_PROXY_TYPE for sensor using raw value.
* It will keep original IIO_SENSOR_PROXY_TYPE and multiple
IIO_SENSOR_PROXY_TYPE support, so risk is low for other hardware.
* Checking on working hardware and run $ monitor-sensor
it should keep popping Light changed event no matter what operations,
close lid, suspend/resume, reboot...etc.
* The change is from upstream which has been in groovy and hirsute.
