Sebastien Bourdeauducq a93fdb8c9d drtio: disable all destinations in gateware at startup
Otherwise, kernels fail to get a RTIODestinationUnreachable exception when attempting
to reach a DRTIO destination that has never been up.

Sebastien Bourdeauducq cc58318500 siphaser: autocalibrate skew using RX synchronizer
* removes the hardcoded, (poorly) manually determined skew value
* does not need si5324_clkout_fabric anymore (broken on Sayma RTM due to wrong IO voltage)

David Nadlinger e608d6ffd3 coredevice, firmware: Add rtio_input_timestamped_data
Integration tests to follow as part of an RTIO counter phy that
makes use of this.

David Nadlinger 8e30c4574b firmware: Treat timestamps consistently as signed [nfc]
This matches other functions and the ARTIQ Python side, but
isn't actually an ABI change.

David Nadlinger d4c393b2a8 firmware/ksupport: Update `cfg(not(has_rtio))` stub signatures
This fixes up 8caea0e6d3,
but it is unclear whether anyone even uses a `not(has_rtio)`
configuration at this point.

whitequark 248c1cf7dc firmware: fix another TOCTTOU race in sync/async RPC code. 2018-11-13 00:58:20 +08:00
whitequark 68aad3e482 firmware: fix TOCTTOU race in sync/async RPC code.
Before this commit, the main loop in session code was laid like:

  1. process_kern_queued_rpc
  2. process_host_message
  3. process_kern_message

If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.

Fix this by reordering 1 and 2.

David Nadlinger b482f5feae firmware: Use larger ARP cache
This works around a problematic interaction between ARP cache
expiry in smoltcp (with its 3 seconds timeout before a discovery
request is sent) and our TCP keepalive settings, where the timeout
is reached before the keepalive had a chance to be sent.

GitHub: Closes #1150.
