Arm-only because the 32 bit userspace vs 64-bit kernel
issues are worse on x86 because of some extra 4 vs 8 byte
alignment (when included in structs) ABI issues.
Wear is unlikely to ever run on comparatively high
power usage x86 cpus, so this should be fine.
Manually tested by adding:
if (isWear()) ALOGI("Wear!");
and additionally logging 'bool watch' within isWear()
on 'cf_gwear_x86-trunk_staging-userdebug'.
Resulting output:
I NetBpfLoad: NetBpfLoad v0.46 (/apex/com.android.tethering/bin/netbpfload) api:35/36 kver:601004b (32-on-x86-64) uid:0 rc:01
I NetBpfLoad: isWear(ro.cw_build.wear_sdk.version=6[6] ro.build.characteristics='nosdcard,watch'[1]): true
I NetBpfLoad: Wear!
