Revert "kernel/spec-fmc: only enable irq1 from fpga" · d5dcd71d

Alessandro Rubini authored Sep 24, 2012

This reverts commit 0dcf4ed3.

After this I started having irq problems (missing events) so I'm not sure
it was the right thing to do. Try reverting as a quick solution for me.

kernel/wr-nic-dio: change of behaviour with periodic pulses · 07f45788

Alessandro Rubini authored Sep 24, 2012

The period pulse on a channel was designed as a generic "mirror one channel
to another with a predefined delay".

However, on different boards self-stamping has different delays, so
if we are mirroring to ourselves, add the delay to the previous setpoint
instead of using the timestamp we got, so the 8ns difference doesn't
accumulate over time.

kernel/wr-nic-eth: wait 1us after serving to vic irq, to force the edge · 1a314643

Alessandro Rubini authored Sep 24, 2012

The Gennum manual doesn't say what is the miminum glitch for it to
detect the edge, but this appears to work. I can't be sure, though.

kernel/spec-fmc: only enable irq1 from fpga · 0dcf4ed3

Alessandro Rubini authored Sep 24, 2012

There's the risk of getting spurious interrupts if the test points are
not connected as I use them, and the same may happen to the unused irq0
pin from the fpga
