<vagrantc> ok, tested the same method with a debian image i built, pinebook and pinebook-pro booting off a single image!
* vagrantc dances
<vagrantc> also happens to be my first live-image i built for debian arm64

<warpme_> jernej: just wonder your opinion: i gave test run for cedrus on h616 with ffmpeg and ffmpeg tells me: "[h264 @ 0x2dd37b10] v4l2_request_try_format: pixelformat 842089294 not supported for type 1" - a bit surprising for me...

<rellla> hi all, i need your help regarding cedrus/cma.
<rellla> i want to reserve cma exclusively for cedrus and thought, this would be the way to do:
<rellla> but then i get the following error messages when probing cedrus:
<rellla> [ 33.085565] cedrus 1c0e000.video-codec: failed to get scatterlist from DMA API
<rellla> what do i miss?
<karlp> dwmac-sun8i should be giving me a stable MAC based on SID? or is that a "distributor hack" ?
<karlp> actually, that's just a distraction for me right now. what's more curious is that using spidev, one board gives me spi lines idling low (and not working), and another idling high (and working) https://imgur.com/a/gDEF7NB
<karlp> the device tree files are default, and there's no physical pullups or pulldowns anywhere. Was this just working by chance on the board that works?
<karlp> should I be adding "bias-pull-up" properties in a device tree overlay for these pins?
<jernej> warpme_; nothing surprising, format NC21 is not supported... Not sure how you got it, it's probably a typo somewhere
<karlp> https://linux-sunxi.org/SPIdev#Bugs.2FCaveats don't seem applicable, they're just related to glitches, which is intereting, but not what I'm seeing.
<jernej> karlp: MAC is generated in U-Boot and DT is patched with it's value on the fly

<jernej> karlp: no idea about SPI, but today few fixes were posted: https://lore.kernel.org/linux-sunxi/20210531044608.1006024-1-roman.beranek@prusa3d.com/T/#t
<jernej> maybe they will help
gamiee has quit [Ping timeout: 480 seconds]
<karlp> those are all PWM fixes?
<jernej> yes, all 6 patches are for same file
<jernej> why not? :)
<karlp> right, but PWM != SPI?
<jernej> ah, crap
<jernej> sorry
<jernej> not sure why I had that in mind :)
<jernej> rellla: not sure if anyone tried it, but early Cedrus driver used CMA from predefined range: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/sun8i-h3.dtsi?id=36c4bef372a114222266858b1f342f7c03fabdd7
<jernej> karlp: there is actually one SPI fix which was submitted last week, but it's basically the same thing that's on wiki
<karlp> yeah, this armbian kernel apparently has both patches anyway, and from the decriptions, they should just be glitches, not permanently low/high.
* karlp tries a 5.9 matching kernel on the failing board, just for starters.
tnovotny has quit []
<rellla> jernej: found that, too. i tried with "no-map" and without specifying the range - and omitting the memory-region in the video-codec node. that seems to do what i want.
<rellla> though i wonder, if i can exclusively reserve a region for video-codec only?
<jernej> no idea, I never tried
<jernej> why do you want to give exclusive region? I never had a need to do that

<karlp> hrm, well, 5.9 kernel is same, and applying bias-pull-up with a dtbo makes no difference either.
