BUILDING.md: the SnapAdreno and SnapI2CHID PROFILE builds, how to
compare one with a deployed kext, and tools/build-auxkc-desktop.sh.
RUNNING.md: --gpu-coherent and --resident-mib in the GPU flag group,
what b12v20 and b12v23 add to the listed desktop configuration, what
--gpu-coherent requires (--gpu-va-wide, --root-cache-wide, the
desktop-profile kext and a q1n1 with `a16gpu adopt --coherent`) and
that --gpu-coherent-force is a debug build.
