Sebastien Bourdeauducq 4941fb3300 sayma: 2.4GHz DAC clocking (4X interpolation) 
* gets another clock divider out of the way
* gets one cycle within range of the HMC7043 analog delay alone
* SYSREF/RTIO alignment removed, to be replaced with DDMTD-based scheme

David Nadlinger 3e84ec2bf1 coredevice.ad9910: Fix phase tracking ref_time passing 
This is difficult to test without hardware mocks or some
form of phase readback, but the symptom was that e.g.
`self.dds.set(…, ref_time=now_mu() - 1)` would fail
periodically, that is, whenever bit 32 of the timestamp
would be set (which would be turned into the sign bit).

This is a fairly sinister issue, and is probably a compiler
bug of some sort (either accepts-invalid or wrong type inference).

Robert Jördens 19748fe495 ad9910: fix RTIO fine timestamp nudging 
Previously the TSC was truncated to an even coarse RTIO periods before doing
the setting SPI xfer. Afterwards the the IO update pulse would introduce
at least one but less than two RTIO cycles. Ultimately the RTIO TSC was
truncated again to even. If the SPI xfer takes an odd number of RTIO
periods, then a subsequent xfer would collide.

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.

Robert Jördens 14b6b63916 ad9910: rewire io_delay tuning 
This now reliably locates the SYNC_CLK-IO_UPDATE edge by doing two
scans at different delays between start and stop IO_UPDATE.
It also works well when one delay is very close to the edge.
And it correctly identifies which (start or stop) pulse hit or crossed
the SYNC_CLK edge.
