The FP6 is 4x Cortex-A520 + 4x Cortex-A720 and this image boots nothing else, so pass the compiler KCFLAGS="-march=armv8.6-a+fp16fml+aes+sha3+sm4 -mtune=cortex-a720". The stock arm64 build gives the compiler no arch flag at all (so one image can boot any Armv8 board). The string is what `gcc -march=native` derives on the phone, re-based on armv8.6-a so clang can express the same set (clang has no flagm2/rcpc2/ frintts tokens; it reaches them through the architecture level). 8.6 is the highest level whose mandatory set the phone exposes: 8.7 would assume WFxT and 9.x SVE2, and neither is in its hwcaps or ID registers. clang emits identical code for this and for -mcpu=cortex-a720+nosve+nomemtag; the difference is only which system features (SPE, ETE, TRBE, FPAC) it knows about, none of which generate code. Verified on eef717f978f1 with the aport config: builds with zero warnings, same module set as r100 (417), compat vDSO untouched, boots the dev phone with a clean dmesg and a GREEN selftest. Record: fp6 journal/base/captures/2026-09-05-mcpu-a720-verification.md.

# fp6-img fork of Alpine community/libqmi: snapshot bumped to upstream main

# just past the !470 merge (LOC Register Events client-identification TLVs,
|
|
# half of working GNSS on the FP6) - which also provides the qmi-glib 1.39.1
|
|
# our modemmanager patches require. Drop when Alpine's snapshot catches up.
