gregdavill: I just merged the eptri cdc stuff. It passes the testbench now (patches pending) with a sysclk of 100 MHz. Still need to feed it a 48 MHz clock. And probably should feed it a 12 MHz clock as well, though I suppose you could just flop it.
<kgugala>
those prints with pll etc means that the device locked on signal (later it prints the delay settings)
<CarlFK>
^c the gst line, re-ran it. it did 45 frames and stopped
<CarlFK>
oh boy. did that 2 more times, now it is working again.
<CarlFK>
cpu - 4 cores, each between 10-20%
<kgugala>
I'd say it's displaying what consumes the cores
<kgugala>
data is transferred over pcie by DMA in fpga
<kgugala>
so it does not consume the CPU
<CarlFK>
the hangs or pause are concerning
<CarlFK>
cpu goes to about 0 when that happens
<CarlFK>
dmesg is full of [67712.275108] x86/PAT: v4l2src0:src:20261 map pfn RAM range req uncached-minus for [mem 0x35e00000-0x35fc1fff], got write-back
<CarlFK>
and this 2x a second: [68401.017895] litepcie ph -5 1 0 // charsync 111 [8 6 6] // WER 0 0 0 // chansync 1 // res 1280x720
<kgugala>
the latter means it does not see the video input
<CarlFK>
swapped cable from short magic to 3' normal probably to spec, same thing in dmesg

kgugala: fps has dropped to 42 - no clue why. nothing has changed as far as I know
<kgugala>
unsure what happened, I was keeping it running for 24h and haven't noticed such issues
<CarlFK>
kgugala: for output, pretty please don't have black be the default for when there is no input.
<CarlFK>
either color bars or some unique color that makes it obvious where the signal is coming from

that just landed in the Opsis, it's helpful. ans surprising because I forgot about it
<CarlFK>
and by "just landed" I mean the patch was accepted in 2019, and someone was able to build it in Jan 2020, and I'm not exactly sure where a working bitstream file is.
