Michael Birtwell 671453938b Require explicitly closing TcpStreams
Instead of automatically closing and draining the TcpStream in the Drop
implementation instead expect the user to call TcpStream::close.
Add close called to all users of TcpStream.
Document the requirement to call close on TcpListener::accept, this seems
to be the only way to get a new TcpStream at the moment.

pca006132 4132c450a5 firmware: runtime changes for exception
Ported from:
M-Labs/artiq-zynq#162

This includes new API for exception handling, some refactoring to avoid
code duplication for exception structures, and modified protocols to
send nested exceptions and avoid string allocation.

whitequark 0edae64afb firmware: fix TOCTTOU race in sync/async RPC code.
Before this commit, the main loop in session code was laid like:

  1. process_kern_queued_rpc
  2. process_host_message
  3. process_kern_message

If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.

Fix this by reordering 1 and 2.

whitequark 9347f6e00c firmware: use a dedicated error type in the scheduler.
After this commit, error handling does not normally allocate
(session::Error::{Load,Unexpected} still allocate, but those two
are very rare).

Good riddance to libstd_artiq.

whitequark 6a10d54432 firmware: migrate rpc_proto to new libio.
This closes an old and horrible issue in that some code in ksupport
may implicitly try to allocate and we'll never know until it crashes
at runtime inside liballoc_stub.

This also removes liballoc_stub.
This also removes ReadExt and WriteExt from libproto.
Hooray!

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