* usrp1: tweaks + implemented other features to mimic async and inline messagesJosh Blum2011-07-021-0/+5
| | | | | | | Moved the underflow/overflow polling into a thread and out of the fast-path. Added an inline and async message queue into soft time control. Error and status messages are actually generated now and enqueued. Passes the async message test...

* e100: implemented spi, i2c, messages w/ peek/pokeJosh Blum2011-06-175-146/+273
| | | | | | | | spi and i2c are done w/ polling, but this is ok, the transactions always complete by the first check a gpio is used to wake up poll() and check for messages. messages are read using poke32, unpacked, and enqueued.
