Sebastien Bourdeauducq 5a2a857a2f firmware: clean up SYSREF phase management 2018-06-21 16:23:41 +08:00
Sebastien Bourdeauducq 1d594d0c97 firmware: make DAC initialization failures non-fatal 
This allows using RTMs with one broken DAC for development.
 2018-06-19 19:09:38 +08:00
Robert Jördens a143e238a8 savel_fpga: get rid of unneeded config 2018-06-12 10:24:04 +02:00
whitequark d686d33093 runtime: print hex dumps around PC/EA in case of exception. 
For #1026.
 2018-06-01 21:17:59 +00:00
Sebastien Bourdeauducq 560889372f firmware: grabber support 2018-05-29 10:26:36 +08:00
Sebastien Bourdeauducq b10d3ee4b4 make RTIO clock switch optional and simplify 
Kasli no longer has an internal RTIO clock.
Switching clocks dynamically is no longer supported.
 2018-05-18 17:41:34 +08:00
whitequark 5744d97d59 firmware: adjust backtrace addresses correctly. 2018-05-17 08:13:55 +00:00
whitequark 31c6c79204 firmware: implement an edge profiler. 
It doesn't work extremely well, and the results can be somewhat
confusing, and it needs a libunwind patch, but it's the best I could
do and it seems still useful.
 2018-05-16 21:53:53 +00:00
whitequark ca93b94aea firmware: move config requests to management protocol. 
They were only in session protocol because of historical reasons.
 2018-05-16 14:32:49 +00:00
Florent Kermarrec 7fe49a78d2 firmware/runtime/session: fix compilation when no rtio core 2018-05-15 23:47:47 +02:00

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.
 2018-05-15 14:19:44 +00:00
whitequark 479cb9a857 firmware: use dedicated error types for every protocol and thread. 
Good riddance to io::Error::Unrecognized.

whitequark 514eab3d39 Update Rust to 1.26.0. 2018-05-15 12:47:51 +00:00
whitequark 26faaad2b7 firmware: remove io::Result<T, E> in favor of Result<T, impl Fail>. 
This doesn't yet use impl Fail since std_artiq::io::Error doesn't
impl it.
 2018-05-15 08:29:03 +00:00
whitequark 140ca729aa firmware: rename io::Error::{UnexpectedEof→UnexpectedEnd}. 
We don't even have files.
 2018-05-15 08:27:45 +00:00

Just replace these with references to alloc.
 2018-05-14 19:11:57 +00:00
whitequark ae50196186 firmware: rename libproto to libproto_artiq. 
libproto_artiq only has ARTIQ-specific protocols.
 2018-05-14 18:09:44 +00:00
whitequark 02b8426f60 firmware: rename libboard to libboard_misoc. 
By analogy with libbuild_misoc. Hopefully one day it actually gets
moved to misoc...
 2018-05-14 18:09:44 +00:00
whitequark 1ff42683d9 firmware: merge libamp into libboard_artiq. 
All gateware interfaces live in libboard_artiq, but libamp predates
libboard_artiq.
 2018-05-14 17:33:25 +00:00
whitequark 764386c9e3 firmware: split libdrtioaux into libproto and libboard_artiq modules.

interfaces live in libboard_artiq.
 2018-05-14 17:26:59 +00:00
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!
 2018-05-14 17:26:59 +00:00

whitequark 0d5fd1e83d runtime: fix race condition in log extraction code paths (#979). 
The core device used to panic if certain combinations of borrows
of the log buffer happened. Now they all use .try_borrow_mut().

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 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 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 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 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.
