Sebastien Bourdeauducq 8399f8893d add kernel access to non-realtime SPI buses (#740) 2017-06-18 12:45:07 +08:00
whitequark b913d1d6f2 runtime: make a copy of startup/idle kernel firmware before loading.
Fixes #716.
2017-04-21 16:46:40 +00:00
whitequark 0e68eaa879 runtime: print a heap dump on out-of-memory condition. 2017-04-21 14:48:10 +00:00
Sebastien Bourdeauducq fe05aede78 firmware: DmaPlayback → DMARetrieve 2017-04-19 11:11:42 +08:00
whitequark c6e8d5c901 runtime: allow setting UART log level explicitly.
This is way more convenient than commenting out parts
of session.rs when debugging.

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

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 14ae1cc100 runtime: advance now on DMA replay.
Fixes #700.
2017-04-05 18:34:36 +00:00
whitequark d04d7ed120 runtime: show a more informative message for interrupted sessions.
Fixes #690.
2017-03-29 03:36:49 +00:00
whitequark 948ed6fb0a Extract core device management interface from session interface (#691). 2017-03-29 03:36:21 +00:00
whitequark c586035caa runtime: add an option to reboot after a panic. 2017-03-14 09:02:28 +00:00
whitequark 795a3e24d8 artiq_coreboot: block until hotswap image is actually received. 2017-03-07 11:36:28 +00:00
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.

whitequark fd8b11532f compiler, firmware: use Pascal strings everywhere.
This removes a large amount of very ugly code, and also simplifies
the compiler and runtime.

whitequark 739da9f1b3 runtime: print trace level log messages to UART during startup.
There's no way to retrieve them otherwise if the startup kernel
hangs.
