%description
Experimental SENEMOS Linux 6.17 kernel channel for Xiaomi Pad 5, built from
source inside COPR. Version v1.4.1.0 combines the reviewed Nabu v1.4.0.9
hardware line with the SM8150 Iris stateful V4L2 driver and opt-in persistent
suspend diagnostics. The Nabu-only CS35L41 power-down quirk accepts a missing
PDN_DONE indication only after confirming that the amplifier is disabled and
no protection fault is active. It remains an alpha release until physical boot,
decode, suspend, audio, Wi-Fi, display and rollback tests pass on the tablet.
