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.	2017-04-15 07:29:52 +00:00
whitequark	14ae1cc100	runtime: advance now on DMA replay. Fixes #700.	2017-04-05 18:34:36 +00:00

whitequark	5d3b00cf12	Implement recording of DMA traces on the core device.	2017-02-26 02:50:20 +00:00
whitequark	a07bd918f0	firmware: use Rust naming conventions for enum variants.	2017-02-25 22:34:11 +00:00
whitequark	2a81819eb0	firmware: restructure to avoid #[path = "..."] mod ...; Such code is fragile, introduces mess in dependencies, and inflates compile times.	2017-02-25 17:54:14 +00:00
