Hermes driver v2 #17

Closed iomartin closed 3 years ago

iomartin commented 3 years ago

PR for v1: #15

v2 includes the following changes:

We now extend and rename the xdma driver instead of creating a separate hermes driver
We remove several parts of the XDMA driver that aren't used by Hermes, including most of the /dev/xdma* devices
Commands are implemented as ioctls instead of write/read
Command responses are now being generated as well
For security, we disable the XDMA channel devices, but allow them to be enabled back through a module parameter
