*: set timeout coalescing dynamically · 013a37f9

Federico Vaga authored Aug 16, 2018

The driver exports a sysfs attrubte to change the coalescing timeout. A new
library funciton can be used to set/get this value; and the test program allows
the configuration before an acquisition.

Keep in mind that, for FIFOs the configuration is global (users are warned on
dmesg) while for DMA it is per-channel. I though it was better to have a common
interface for both. Users are warnd in the documentation as well. In the long
run, perhaps also the FIFO can have its own register.

drv: bugfix, do not touch burst size dynamically · 8f34868a

Federico Vaga authored Aug 17, 2018

It is not an IRQ coalescing size, but the size that triggers the dump
from the FIFO to the DDR. so, it is internal stuff that does not need
to get exposed to the user

drv: bugfix ZIO names are 12bytes, make this 11 · cc39d6ac

Federico Vaga authored Aug 17, 2018

This way the name is properly terminated. Perhaps there is a bug in ZIO
that expect a \0 and it does not check any upper limit.
