[Cialug] Raspberry Pi 3

[jim kraai]

this probably isn't a surprise or really helpful, but just in case ...

about power consumption.  all micros have a sleep/halt mode, amiright?

huh, Pi has no explicit HLT/sleep mode

WFI, Wait for Interrupt, puts the cpu into standby mode with core down and
caches up

looks like no support for either under linux
