Qs315490
416017bd34
The kernel version has been updated to mainline 6.16.0 and successfully compiled and tested. Due to the device's specific requirements, it enforces the use of Secure Boot. Disabling Secure Boot will reset it back to enabled after several reboots or DNX Fastboot sessions. I had to resort to using shim and a self-signed certificate. https://wiki.postmarketos.org/wiki/Xiaomi_Pad_2_(xiaomi-latte) Part-of: <https://gitlab.postmarketos.org/postmarketOS/pmaports/-/merge_requests/7286>
