Hello, I compiled gsi for my mix2s, and found the nfc does not show up in system settings. I searched the log and found it complains a lacking nxp nfc library. Then I compared with stock system image and modified devices/phh/treble/base.mk to add these lines:

PRODUCT_PACKAGES += \
    libnqnfc-nci	\
    com.nxp.nfc.nq	\
    com.gsma.services.nfc	\
    libnqnfc_nci_jni	\
    com.android.nfc_extras

Then logcat shows:

Could you please tell me how to make selinux happy about the nfc? Or I'm doing something wrong? Thanks very much!

Well, I'd like to start from scratch. There is no reason you'd need those libs, so please provide logs without those. And I'd rather get logs on AOSP if that's possible

On the SELinux issue itself, your problem is that com.android.nfc gets seinfo default, while it should get seinfo platform. If you don't get the proper seinfo, it means your Nfc app isn't properly signed. It should be signed with ROM's platform certificate

Today I flashed your AOSP v19 image and NFC is working. Seems a LineageOS specific problem.
