whitequark 74b7010d67 runtime: allow safely pulling logs even on TRACE log level. 
Before this commit, this resulted in a packet flood, because
sending a TRACE log message to the host caused more TRACE log
messages to be emitted.

Sebastien Bourdeauducq 44edba0c65 firmware: add placeholder code for HMC830/7043 initialization 2017-08-31 13:35:47 +08:00
whitequark 20f43d5792 firmware: fix ethmac MTU value. 
1500 is the maximum payload size, not maximum frame size.

whitequark 737c1044a4 firmware: update smoltcp. 2017-08-31 00:45:56 +00:00
whitequark f26e698f31 Revert "firmware: reduce ethmac maximum burst size by one." 
This reverts commit 2231b16e0a.

Only made a difference with TRACE log level to UART, i.e. only
because UART was the bottleneck.

whitequark 39ecbc0d68 firmware: update smoltcp. 2017-08-30 14:35:45 +00:00
whitequark 2231b16e0a firmware: reduce ethmac maximum burst size by one. 
Empirically, this much reduces packet loss. I'm not really sure why,
but it seems safe to do the change.

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 c6e8d5c901 runtime: allow setting UART log level explicitly. 
This is way more convenient than commenting out parts
of session.rs when debugging.
 2017-04-15 08:27:18 +00:00
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.

whitequark b0cdef3211 firmware: implement hotswap through artiq_coreboot tool. 2017-03-06 16:01:28 +00:00
whitequark 98454e9bda runtime: remove unnecessary dcache flush. 
Data cache is write-through, so sending data to DMA doesn't need
a flush.
 2017-03-04 09:46:55 +00:00
whitequark 924ae73000 firmware: fix DMA trace alignment and flush caches. 2017-03-04 09:40:22 +00:00
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. 
This shouldn't affect performance much, as the log crate guards
every log statement with a branch, adding just two instructions.
 2017-03-03 06:06:26 +00:00
whitequark fe77fcc45f firmware: fix a warning. 2017-03-03 05:35:28 +00:00

Sebastien Bourdeauducq 7481eaff52 moninj: use smaller network buffer 2017-02-27 11:44:29 +08:00
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.

whitequark 259319e456 firmware: use compiler_builtins crate instead of our compiler-rt. 
This cannot be done for ksupport yet because compiler_builtins

whitequark ee1b2fa3ea compiler: swap the order of ptr/len fields in lists. 
This is to make them match the Rust slices.
Once the cslice crate becomes #![no_std] we'll also use its (tidier)
conversion functions.
 2017-01-31 22:11:13 +00:00
whitequark b95db4fa4e Use four ethmac buffers instead of two. 
This should address an issue where the host sends a packet burst,
the second packet in a burst gets dropped, the rest also gets
dropped since smoltcp doesn't do reassembly, and the entire dance
is repeated on every retransmit.

Sebastien Bourdeauducq 54295b1699 firmware: use has_ad9154 instead of has_converter_spi for conditional compilation
