Robert Jördens 55b5b87490 fir: simplify latency compensation 
Don't try to tweak out the last bit of latency by feeding the HBF input
early. Instead feed it late so the interpolated samples are early and
the latency is an even multiple of the super-sample cycle.

whitequark 370f22541c runtime: update smoltcp. 2017-06-27 21:06:45 +00:00
whitequark f36f00a83d artiq_devtool: do not chop up the TCP stream into 1024 byte chunks. 
This makes the smoltcp behavior quite different than without
the TCP forwarding (and can mask smoltcp issues).

whitequark 282f4256e0 artiq_pcap: atomically replace pcap file.

whitequark 31b52ff1b3 coredevice: do not desync kernel TCP stream on RPCReturnValueError. 
And propagate the error upwards instead of trying to squeeze it
through the core device in futility.
 2017-06-25 04:47:32 +00:00
whitequark fdb24ef139 coredevice: truncate overlong exception messages. 
If we have a really long one (megabytes) then this may exhaust
the heap of the core device and crash it.
 2017-06-25 04:39:08 +00:00
whitequark 1fa8be3835 artiq_devtool: don't loop forever if core device dies. 2017-06-25 04:18:45 +00:00
whitequark f17a6616b2 runtime: ensure management interface buffer can hold log buffer. 
Otherwise we get weird edge cases where the network stack could try
to append to log buffer while management interface is holding
the log buffer and trying to push it out, and it's just no good.

The serialized log buffer at its maximum length is slightly longer
than 32 KiB, so we just allocate the largest possible TCP buffer
to the management interface to keep it simple.

Robert Jördens 219dfd8984 rtio: add one register level for rio and rio_phy resets 
* This should give Vivado some wiggle room during PnR.
* It needs three new clock domains which is ugly. But since
AsyncResetSynchronizer can only drive clock domains resets directly
there seems to be no other way to add one register level currently.

Robert Jördens 315338fca9 test/sawg: test HBF overshoot, fix sim patching 2017-06-12 20:35:47 +02:00
Robert Jördens 9a8a7b9102 sawg: handle clipping interpolator 
* give 1 bit headroom to interpolator to handle overshoot
* fix Config limiter widths (NFC)
* move clipper to behind the HBF to correctly shield DUC

This leaves a factor of two headroom for the sum of the following
effects:

  * HBF overshoot (~15 % of the step)
  * A1/A2 DDS sum

While this is technically not sufficient and can still lead to
overflows, it is unlikely that one would trigger those. It would require
doing large amplitude A1, large amplitude A2 and additionally doing
amplitude/phase jumps that would overshoot the HBF. No sane person would
try that, right?

closes #743

whitequark 41c4de4556 DMA: add API for a much faster replay using handles. 2017-04-18 08:20:12 +00:00
whitequark c6e8d5c901 runtime: allow setting UART log level explicitly. 
This is way more convenient than commenting out parts
of session.rs when debugging.

whitequark 0531dc45c3 DMA: erase trace before re-recording it. 
Or we could needlessly OOM replacing a large trace.

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.
