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.

 2018-08-12 20:17:37 +00:00
whitequark 38d60100ff firmware: optimize dma_record_output. 
This removes a number of bounds checks and adds a fast path for
outputting exactly one word to DMA, which is the most common
operation.
 2018-08-12 19:17:45 +00:00
whitequark 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.

Robert Jördens a44f8282dc test_performance: relax network speed to 2 MB/s 
At QUARTIQ I am getting 2.4/2.3 MB/s and with single switch at M-Labs we
apparently regularly met 2.2/2.2 MB/s. But with the current multiple
switches and one of them being a problematic switch that triggered #837
it looks like it is a tad slower.

whitequark 9dfe9c1248 DMA: improve recording performance. 
This commit moves DMA serialization code to the kernel CPU
(to cope with the existence of rtio_output_wide) and batches
the resulting sequences. This results in less data being transferred
between kernel and comms CPUs (24 octets with one pointer before,
18 octets with no pointers now, for the common case of rtio_output),
but most importantly reduces cache flushes, which now happen
once per 64k octets.

On average, it now takes about 15us to record a single RTIO event
in a DMA trace.

Fixes #712.
