fp6-no-suspend -> fp6-device-tweaks: + the three IMU-critical /etc files
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).

# Device-critical FP6 configuration that no upstream package ships yet —
|
||||
# every piece here was once a hand-applied /etc file on the dev phone that a
|
||||
# reinstall silently lost:
|
||||
# - masked sleep targets: wifi and BT share the WCN combo chip; idle-suspend
|
||||
# (and BT-off) resets the shared firmware and kills wifi for ~40 minutes
|
||||
# - inv-icm42600-spi module-load: the IMU sits on bitbanged SPI with a
|
||||
# fallback-only DT node, so udev coldplug never autoloads it
|
||||
# - accel poll udev rule: inv_icm42600 exposes scan_elements without a
|
||||
# trigger; iio-sensor-proxy must use its poll backend or auto-rotate is dead
|
||||
# - iio-sensor-proxy restart drop-in: revives it after the known boot-time
|
||||
# libssc crash on unconfigured SSC
