Full-system audit on the flashed phone found the IMU dead: the journal's documented reinstall-loss trio (inv-icm42600-spi modules-load - fallback-only SPI node never coldplugs; the accel poll udev rule for auto-rotate; the iio-sensor-proxy libssc-crash restart drop-in). All device-critical, none personal - now packaged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# FP6 / inv_icm42600: force iio-sensor-proxy onto its POLL accel backend.
|
|
#
|
|
# inv_icm42600 registers no IIO trigger (software kfifo buffer pushed from the
|
|
# INT1 handler), but it does expose scan_elements/, so 80-iio-sensor-proxy.rules
|
|
# tags the accel with BOTH "iio-poll-accel" and "iio-buffer-accel".
|
|
# iio-sensor-proxy 3.9 tries iio-buffer-accel first, fails the trigger lookup
|
|
# ("Could not find trigger name associated with ...") and does NOT fall back to
|
|
# polling -- it registers the device anyway, so HasAccelerometer is true while
|
|
# sensor_device stays NULL. Every ClaimAccelerometer then hits
|
|
# "driver_set_polling: assertion sensor_device failed", AccelerometerOrientation
|
|
# is stuck at "undefined" and Plasma auto-rotate is dead.
|
|
#
|
|
# Glob the name: the DTS carries an icm42630/icm42631 compatible pair, so the
|
|
# IIO name follows whichever the fallback binds (see journal/imu/status.md).
