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 6a49c114c8 runtime: update smoltcp. 2017-06-28 00:27:22 +00:00
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).
 2017-06-26 08:39:16 +00:00
whitequark 282f4256e0 artiq_pcap: atomically replace pcap file. 
Otherwise this segfaults Wireshark (?!).

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.
