Florent Kermarrec c8fcaaea2d integration/soc: use self.irq.enabled instead of hasattr(self.cpu, "interrupt"). 2020-11-30 10:17:03 +01:00
Florent Kermarrec 146068b048 integration/soc/SoCIRQHandler: be sure IRQs can only be added when enabled.
This prevents adding peripherals that requires IRQ support to SoC not supporting
them. Enabling is done automatically when a CPU with interrupt support is added,
but this can also be added manually.

David Shah 61895bef37 rocket: Fix UB due to optimised away DFFs
As both clock and async reset for the debug DFFs were 0, and there was
no initial value on them, they were being validly optimised away by
newer Yosys versions to 1'bx which was propagating into and breaking the
core.

This fixes the problem by tying the async resets to the CPU reset
signal.

Florent Kermarrec 4a748a53b8 soc/interconnect/packet: add initial PacketFIFO.
For now just ensures that we have a full packet in the FIFO before setting source.valid.
It would be nice in the future to also be able to discard packets in the FIFO.

Florent Kermarrec 3d2574a488 tools/remote/comms: base CommXY on CSRBuilder to allow using Comms directly in python scripts.
This way, user scripts can be use RemoteClient (communicating with the Server that has
already been opened on the right interface) or directly use CommXY in the scripts.

Using RemoteClient is more generic but can be slower (due to the Etherbone encoding between
the client and server). On fixed configuration using CommXY directly can then be faster
and also avoid manual opening of the server.
