Maybe the fact that all the GPIO registers and the timestamp counter are on the VC4 side of the SoC. The Linux kernel just reads those when it gets interrupted by the VC4, the ARM subsystem doesn't have any connections of its own to the outside. On another tangent back to NTP, I'm wondering if it wouldn't make sense to offload the timestamp filtering at least to the VC4. Most NTP boxes would run headless anyway, so there'd be 16 processors sitting idle for that sort of thing. >> There seems to be nothing up yet for the BCM2837 (Pi3), but it's >> basically just replacing the A7 cluster in the BCM2836 with an A8 >> cluster. > > Yeah, I'm wondering why the dealy in Linux kernel for 64 bit A8? It wouldn't buy anyone anything of immediate use except having a complete additional distro to build and maintain and more memory pressure to deal with. I suspect that eventually a 64bit port will be added anyway to tick a checkbox somewhere.
