Adding atomic packet example #808

Closed dpetrisko closed 1 year ago

dpetrisko commented 1 year ago

This PR adds the ability to do AMO.ADDs from host to manycore DRAM space. This can be useful for synchronization between host and device

Question: Is there a low-overhead function to detect that an NPA is a DRAM address? Would like to add the check to amoadd because I believe sending an AMOADD to a vcore tile could cause a hang.

Check in some of the config headers. Grepping for "is_dram" should turn something up.

Found it, thanks!
