%description
Experimental SENEMOS Linux 6.17 kernel channel for Xiaomi Pad 5, built from
source inside COPR. Version v1.4.1.1 combines the reviewed Nabu v1.4.0.9
hardware line with the SM8150 Iris stateful V4L2 driver and opt-in persistent
suspend diagnostics. It gates NVT double-tap reports during the pre-freezer
suspend transition to avoid an immediate pm_wakeup_pending() rollback and the
associated ADSP recovery failure. It remains an alpha release until physical
boot, decode, suspend, audio, Wi-Fi, display and rollback tests pass on the tablet.
