whitequark 370f22541c runtime: update smoltcp. 2017-06-27 21:06:45 +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.

whitequark 0531dc45c3 DMA: erase trace before re-recording it.

 2017-04-15 07:48:02 +00:00
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.

whitequark 4f94709e9f firmware: move packet dumps to the DEBUG log level. 2017-03-03 06:11:35 +00:00
whitequark e8c093deb3 Allow changing runtime log level without recompilation.

every log statement with a branch, adding just two instructions.

whitequark 88bf7d2233 firmware: specialize protocol read/write functions. 
Before this commit, proto::io::{read,write}_* functions were taking
a &mut {Read,Write}. This means a lot of virtual dispatch.
After this commit, all these functions are specialized for
the specific IO trait.

This could be achieved with just changing the signature from
  fn read_x(reader: &mut Read)
to
  fn read_x<R: Read>(reader: &mut R)
but the functions were also grouped into ReadExt and WriteExt
traits as a refactoring.

Initially, it was expected that the generic traits from
the byteorder crate could be used, but they require endianness
to be specified on every call and thus aren't very ergonomic.
They also lack the equivalent to our read_string and read_bytes.

Thus, it seems fine to just define a slightly different extension
trait.

This also optimized the test_rpc_timing test: 1.7ms→1.2ms.
