ba4bf6e59b kasli: don't pass rtio pll feedback through bufg
UG472: "The MMCM performance increases because the
feedback clock is not subjected to noise on the core supply since it
never passes through a block powered by this supply."

cbdef0225c ttl: Add target RTIO time argument to timestamp/count functions

17a5fb2dce ttl: Remove error-prone sync() calls
These methods are problematic, as with DMA in the picture, the
timestamp member variables did not necessarily reflect the last
submitted event timestamp (see GitHub #1113).

sync() is only very rarely used in typical experimental code, so
the methods are removed without a transition period.
Core.wait_until() can be used to busy-wait for a specified RTIO
timestamp value on the core device CPU instead.

cbfbe24d7a ttl: Remove broken TTLClockGen.sync
The code currently doesn't compile because of a typo in the timestamp
field name. However, tracking event timestamps in software is
problematic anyway (e.g. with DMA, see GitHub #1113), so just remove
`sync()` altogether.

The docstrings are quite minimal still, but should already

accustomed with the code base.

RIDCounter was moved to its own module, as it isn't really
related to the other classes (used from master only).

This works around a problematic interaction between ARP cache
expiry in smoltcp (with its 3 seconds timeout before a discovery

2648b1b7a1 firmware: migrate to Rust 1.28.0.
This also updates / is a prerequisite for updating smoltcp.

Rationale for changes made:
  * compiler_builtins is now shipped in the rust prefix.
  * rustc's libpanic_unwind no longer works for us because it
    has a hard dependency on Box (and it's a horrible hack);
    fortunately, we only ever needed a personality function
    from it.
  * panic and oom handlers are now set in a completely different
    way.
  * allocators are quite different (and finally stable).
  * NLL caused internal compiler errors in runtime, so code using
    NLL was rewritten to not rely on it and it was turned off.

141fcaaa8a worker_db: Only warn on repeated archive read if dataset changed
In larger experiments, it is quite natural for the same dataset
to be read from multiple unrelated components. The only situation
where multiple reads from an archived dataset are problematic is
when the valeu actually changes between reads. Hence, this commit
restricts the warning to the latter situation.

4359a43732 compiler: Indirection status of TTuple depends on elements
For instance, TTuple(TList(TInt32())) has indirections, while
TTuple(TInt32()) does not.

This fixes memory corruption with RPCs that return tuples of lists.

729ce58f98 sayma: use GTP_CLK1 to clock DRTIO satellite transceiver
This is required to get constant skew between the DRTIO transceiver clock
(which then generates the RTIO clock) and the siphaser reference clock.

Both the Si5324 and the RTM clock tree have non-deterministic in-to-out skew
at 150MHz due to dividers.
2018-06-28 11:23:40 +08:00
a65721d649 sayma: put RTM clock tree into the siphaser loop
* Fixes one bug where siphaser was one Si5324 output and the rest of the
system was clocked by the other. With the Si5324 settings we have, skew
between the outputs is not controlled.
* Puts the coaxial cable between AMC and RTM into the siphaser loop.
