formatters in log() from the kernel CPU are broken
Formatters (%) result in bogus values being printed.
Support numpy scalar types in pyon
This will be mostly useful for RPCs.
process termination in controller manager is broken
This line raises an exception:
https://github.com/m-labs/artiq/blob/master/artiq/frontend/artiq_ctlmgr.py#L69
as it ends up doing https://github.com/m-labs/artiq/blob/master/artiq/tools.py#L98 but the process is created with stdout=None

The text "sync()" appears in the artiq manual but using the web-based search for "sync()" doesn't find it.
influxdb_bridge: filtering
master...fallen:influxdb_bridge
The full change rate of the parameter db will be more than we want to archive. We could simply use a few entries to control it. A list of regexps or globs history_filter to limit the logging by parameter name (probably something like the gitignore style precedence rules and syntax) and a history_rate rate limiter.
Also, the schema (ha!) should be changed a little looking at influxdb 0.9: series name should be "lab-name.parameter" (e.g. "rfjunction2.parameter") and then using tags for the parameter name and the only column should be "value". And afaict things like arrays might break the current implementation as json will not immediately be able to serialize them.
Finally, could the influxdb_bridge be just a concurrently running experiment in its own queue or does that break?
document how to set proper permissions on lda devices
so that the controller does not have to be run as root.
RTIO loopback test fails on Pipistrello
It worked on the KC705 during the tests we did in the lab 2 weeks ago. It was broken before the Quantity removal and machine units refactoring.

Fix RPC race condition
There is some race condition that intermittently causes a complete freeze of the comms CPU when doing lots of RPC over TCP. The rpc_timing.py benchmark is good at causing the problem. Things work fine with serial.
Fix this bug properly and revert commit 37ac6c4.
remove hack to wait for process termination when Python 3.5 is out
artiq/tools.py : asyncio_process_wait_timeout(process, timeout)
Remove this when it will not be needed anymore (when yield from asyncio.wait_for(process.wait()) will not have any issue anymore).
Likely when Python 3.5 is out (September 13th)
AttributeError: 'TdcSim' object has no attribute 'close'
when terminating the tdc controller in simulation mode.
Make Qt + asyncio + UDP work on Windows
The GUI needs UDP to talk to the core device in the TTL and DDS panels. On Windows, the quamash event loop is based on ProactorEventLoop which does not support UDP.
Error(s) in KC705 pin definitions
Attempting to allocate all 16 TTLs for KC705 results in KeyError: 'LA00_CC_P'

#self.run2()develop generic pattern to compensate for delays/latencies
The reference plane for "time" is defined to be the rtio-clock side of the FIFOs, where the rtio counter lives. Latency compensation for delays happening from this plane to any other point in the downstream signal path (DDS DAC output, DDS amplifiers, TTL driver output, cable ends, shutter delays) should be done in software and be configurable in the ddb.
We need an example how to do configurable delay compensation for TTL (rising and falling edges independently), DDS, and DAC outputs. Latencies will be in the ns-µs range but the required compensation may be negative. The case of a TTL-shutter with several ms latency might be a bit tricky because of the required headroom of the rtio counter w.r.t. now but also educationally interesting in demonstating "how to alter the past".
(c.f. #36 for a DDS latency contribution)
installation of flterm
How do I install flterm? The following instructions don't work.
http://lekernel.net/blog/2009/10/debian-packages-for-milkymist-development-tools/
http://installion.co.uk/fedora/19/os/f/flterm/en/install/index.html
Python compiler: place compile-time constants into .rodata when possible
that would reduce code size for experiments needing large tables of data (e.g. randomized benchmarking).
Add context info to RTIOUnderflow exceptions
To be able to debug and solve RTIOUnderflows, we should add a few easily reachable pieces of information to the exception:
- rtio channel number
now()- the amount of the time violation.
Metadata in exceptions would be required for this. Full debugging information (AST nodes to ELF debugging symbols) is for later.

bitstreams Drivers misoc openriscmaster/gui: logging messages
One dock within the GUI will be showing logging messages from the scheduler, the workers, the experiments, the controllers, the core device. Probably, the master will act as a hub rceiving aggregating messages and then save them to files and re-emit them to the GUI. The GUI can then filter on severity, source, or other metadata within the LogRecord (like experiment name). We need to decide whether python-logging fits the requirements (metadata with LogRecords, networking, interaction with asyncio, lazy formatting) or whether we need to roll our own.
rename llvmlite-or1k package name from llvmlite to llvmlite_or1k
14:42 < rjo> ysionneau: good that you added the -or1k suffix to the llvmlite package.
14:43 < rjo> ysionneau: but: it would be really great if we could also install that under that name
(llvmlite_or1k) in the package tree
14:43 < rjo> because then you can actually install your regular native llvmlite in parallel with the
one linked against the or1k-llvm
14:45 < rjo> afaict there would just be a bunch of s/llvmlite/llvmlite_or1k/ in the artiq source.
14:45 < rjo> the native llvmlite is used by numba, which i tend to use.
14:46 < ysionneau> ah ok
14:46 < rjo> ok if i file an issue for this to keep track?
14:46 < ysionneau> yes sure
14:46 < ysionneau> but I'm not sure I understand exactly how to do that
14:46 < ysionneau> in $HOME/miniconda3/pkgs the name of the package is already -or1k
14:47 < rjo> yes. but in the install tree.
14:47 < ysionneau> ah in pkgs/llvmlite-or1k-0.2.1-py34_0/lib/python3.4/site-packages
14:47 < ysionneau> ok
14:47 < ysionneau> I guess it's a setup.py option?
14:47 < ysionneau> to change the package name
14:47 < rjo> less an option. more a field.
14:47 < rjo> exactly.
14:48 < rjo> would need to patch that.

delay(1*ms)if connection to Master is open.... does idle_kernel automatically run if the Master hangs?
If TCP connection is open to Master as when loading a new kernel, does idle_kernel automatically run if the Master hangs? No. SB is working on this. He's looking into using LWIP_TCP_KEEPALIVE.
lda driver supports using the first enumerated device, but controller does not expose this option

flash_storage issues
- the method of access to data fields is inconsistent across functions (
union seek,*(unsigned int *)addr == END_MARKER, etc.). I guess you can removeunion seek. write_at_offsetmay access buffers beyond their length due to the added alignment padding. Likely harmless, but not a clean programming practice.fs_writewill break if the data contains the FFFFFFFF pattern. Forgot to usegoto_next_record?- you can probably remove some of the casts and clutter by trying to use
int(instead ofunsigned int) everywhere. strlenmay crash if a record is corrupted. Usestrnlen. Generally make the code resistant to broken data.- variable names are inconsistent (e.g.
buflenvs.key_len) fs_writeshould return a status code indicating if the data was successfully written or not.
NB: All those bugs would have been prevented by using YAFFS.
needs compiler optimization
This experiment script was marked for bug reporting. SB, do you recall the problem? I'm applying a 1 MHz external pulse train to PMT1.

Using KC705 in Penning lab. Connected to legacy Penning hardware using FMC-LVDS adapter.
In test mode run DDS tests on AD9858. Generates all 1111's.
py2llvm: unroll loops based on necessity and not size
Loops should be unrolled in py2llvm when required by control flow (e.g. interleaving). Other unrollings should be left to LLVM.
Simultaneous FUD on QC2 DDS hardware
The QC2 (clock lab) DDS hardware has one-hot selection signals, which makes it possible to FUD several channels at the same time.
update the transport example to use artiq.wavesynth.coefficients
The transport example is currently broken:
https://github.com/m-labs/artiq/blob/master/examples/master/repository/transport.py
travis: do not build the bitstreams and do not upload for non-master or pull-reqs
Previously the bitstream was not build on pull-requests (no access to the secrets), using BUILD_SOC. With the conda builds, we still can not build bitstreams for pull-requests (yet we should still run the testsuite). We can keepl building the bitstreams for non-master builds. But more importantly we should not upload the packages to binstar if TRAVIS_BRANCH!=master.
artiq_rpctool list-methods should print class docstring
future feature: real-time monitoring of critical PHYs
future feature: Built-in monitoring of status of critical PHY's that trigger idle_kernel if violated. For example, too high duty cycle for a particular device. Or, too long between cooling pulses.
question: should we compensate for latency of FUD to DAC output of DDS (pipeline delay)?
logging formatting styles cleanup
The logging message formatting is a inconsistent. Let's do the following:
style="{"should be added to https://github.com/m-labs/artiq/blob/master/artiq/tools.py#L61- https://github.com/m-labs/artiq/blob/master/artiq/coredevice/comm_serial.py should be cleaned up to use
logger.level("format {}", *arguments)instead oflogger.level("format {}".format(*arguments)). The latter is always evaluated which the former is evaluated only on message emission. - all the other uses of logging should be switch from
%to{}formatting.
feature request: DDS bus reset
Command to reset all DDSs on DDS bus without requirement to reset FPGA.
RTIO exception parameters are broken
Stuck at 0, e.g.
artiq.coredevice.runtime_exceptions.RTIOUnderflow: at 0 ps on channel 0, violation 0 ps
DDS FIFO depth of 64 entries is too small; increase to 1024
