<megi> diizzy: ^ hopefully not too late
* willmore fears diizzy is on fire.
<megi> :)
<diizzy> heh
<diizzy> No, it's crosscompiling
vagrantc has quit [Quit: leaving]
<willmore> Yay!
<diizzy> Hmmm...
<diizzy> btw, eth seems to be a bit wonky i mainline (5.7)
<willmore> On h6?
<diizzy> yeah
<diizzy> well, as close to mainline as libreelec (master) is
<willmore> Gotcha.
<willmore> I'm not sure what I run on my OpiOnePlus.
<diizzy> refuses to boot when eth is attached from cold boot, leds are acting very strange
<diizzy> but it doesn't seem to drop link
<willmore> Power supply sequencing issue?
<willmore> Forgetting to shut things off when powering down?
<diizzy> I tried two different ones 2A+ that runs other SBCs just fine
<diizzy> so I'm quite sure its not a psu issue
* willmore is hacking on surplus server power supplies (hulking 870W things). Pretty sure I have enough power...
<diizzy> I mean, it works fine if you wait until you see the slash screen
<willmore> Could be something in the init of the tranceiver chip. I forget the name for them.
<diizzy> Yeah, it seems to hang pretty much instantly
<diizzy> I should probably hook up serial at some point
<willmore> Got kernel debugging on?
<willmore> LOL, yeah, that's where I was thinking you should go.
<willmore> earlyprintk and all that joy.

<megi> if you'll see phy attaching issues (timeout) it's probably the same issue that Opi 3 has (the circuit looks identical, for sure)
<diizzy> I'm fairly sure it did work earlier like a few months ago but I might be wrong
<diizzy> megi: ...which I guess is non fixable?
luke-jr has joined #linux-sunxi
<megi> no, it's fixable, I have it fixed on Opi 3
<diizzy> hammer? :P
<megi> it's just that power supplies for the phy have to be enabled at the same time
<megi> and they are not in some cases
<diizzy> ...okay?
<megi> like every boot :)
<diizzy> dts hacking? :)
<diizzy> or possibly uboot?
<megi> you have to fix ATF
<megi> and the driver
<diizzy> so it boils down to dodgy hw *sigh*
<megi> no, dodgy sw
<megi> ATF is just wrong
<diizzy> okay
<megi> this should help fixing it
<diizzy> cool, is that 5.7 friendly?
<megi> yes
<diizzy> awesome, I'll give that a try
<megi> if you want a better description than what's in my patch... https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/4642/1
<diizzy> I think I kinda understand the issue

<diizzy> megi: Awesome, all issues are fixed now!
<diizzy> jernej: it does, it least my board (same guy as on the forums)... I bumped atf and applied cpufreq support, works great! :)
<jernej> megi: smauel: what are improvements in atf v2.3 for sunxi socs?
<jernej> diizzy: if you're able to test stability of cpufreq on each point, please sent patch upstream
<jernej> but that's hard on LE, so I suggest some more general purpose distro
<diizzy> I can give it a try, I'm not a linux-guy however
<diizzy> It's also a lot snappier which is to be expected, doesn't seem to perform much better than amlogic s905x @ 1.5Ghz at least not as far as Hi10p is concerned
<jernej> well, 10-bit videos are supported only for HEVC
<diizzy> But it runs a lot better than without cpufreq =)
<diizzy> Yeah, I honestly didn't expect 300Mhz per core to do much
<diizzy> Not sure if they share the same L2 cache size
<jernej> ?
<jernej> it should be around 800 MHz
<diizzy> I'm comparing S905X to H6
<jernej> I know that rockchip socs support HW decoding of 10-bit H264 videos, but I'm not sure if it is already supported in LE
<diizzy> In come cases indeed, I'm talking about software decoding on both platform
<diizzy> that said, it would be better to use something more scientific than video playback
<jernej> anyway, 10-bit currently doesn't bring much, because at the end, RK, AML and AW SoCs doesn't support 10-bit display output yet (is in the works)
<diizzy> Hmm... I wonder where Kodi tries to grab cpu speed
<jernej> why would you use SW decoding if HW decoding is available?
<jernej> or you're doying some kind of CPU benchmark?
<diizzy> It's not on H264 10-bit?
<diizzy> No, it was mostly an attempt to see if I needed beefier (faster) hardware
<diizzy> hw should ofc be used if available, I dont see why you wouldn't use it
<PPA> On the topic of HW decoding, is there a linux-noob-friendly introduction anywhere on what components have to be put together to get it working?
<PPA> From cursory reading, I gather that there's Cedrus as the thing that works directly with the hardware,
<PPA> there are libraries (this libvdpau/VA-API stuff) which allows user applications to interface with Cedrus,
<PPA> and finally, the programs used (e.g. Kodi, ffmpeg…) need to be able to work with those libraries?
<diizzy> Seems to hover around 63C with a very beefy heatsink
<diizzy> PPA: probably not, looks like you need patches as pretty much everything is bleeding edge
<PPA> Ah, thanks. That may be a bit too much for a beginner.
<diizzy> I guess the quickest way would be to rip out it from LibreELEC or something
<diizzy> but its probably "not worth it" if you're just going to play around
<PPA> yeah
<jernej> yeah, HW decoding is far from beginner friendly
<jernej> but there is a light of hope that things will stabilize in next or two kernel releases
<jernej> by that I mean 5.9 or 5.10
<diizzy> So ~about 1 year or so heh
<jernej> nope, half a year
<jernej> last week iirc was first serious suggestion to make H264 interface public (along with few modifications)
<jernej> so once interface becames public, it will become official UAPI, which means it will stop changing
<diizzy> one thing is for sure, cpufreq on H6 would for sure overheat/thermal throttle a lot on most H6 platforms
<PPA> Thanks for all the hard work on making these things functional, by the way
* diizzy looks the dinky H6 "media players" with abysmal heatsinks
<jernej> diizzy: I will probably make H6 configuration separate from other 64-bit AW SoCs
<diizzy> and the orientation of the IR sensor on this board kinda sucks
<jernej> it's different enough to have different optimum settings
<diizzy> what would that be, different govenor?
<jernej> for one thing, then it has iommu which will be supported by 5.8
<jernej> with iommu, CMA is not needed and kernel can use better memory management
<diizzy> I dont see any obvious improvements as far as libreelec goes but then again I'm not familiar with the inner workings
<jernej> well, thermals are important
<jernej> and one user besides you already reported high temperatures
<diizzy> I thought people already knew that H5/H6 could be quite toasty
<jernej> H6 is also first which supports 10-bit 4K@60Hz (4:2:0) output (not implemented yet)
<jernej> with proper devfreq governor, temperatures can go lower, for sure
<jernej> I think that in the past, I saw cores at 432 MHz (something like that) on H3, because HW did everything else
<diizzy> Not to rain on the parade or anything but I get the impression that Allwinner is loosing ground to rockchip and amlogic quickly :/
<diizzy> I think H3 does 600-something ootb

<jernej> I'm pretty sure AW is aware of their position and I heard for some new SoCs in the pipeline
<jernej> but we'll see if they'll stick or not
<jernej> anyway, I have to go
<diizzy> I'll try to do some testing and submit upstream
<diizzy> not sure how to handle the atf patch however
<diizzy> as it seems to be a no go upstream

<s3b0> does anyone could explain for me what could be wrong: https://www.youtube.com/watch?v=3PXFE7nogJI ?
<s3b0> i have 7" lcd for bananapi (Lamobo-R1)
<s3b0> and i can't make it work in linux
<s3b0> i was able to enable it in u-boot
<s3b0> but linux disaplays only garbage

<diizzy> megi: network leds are still wonky but at least it boots :)
<megi> good
<megi> not sure what you mean about wonky leds
<megi> for me on opi3 orange one blinks periodically, and green one on traffic
<diizzy> link led goes on and off within a few seconds
<diizzy> Well, I assume its supposed to be a link led
<megi> I wanted to shut dem off, but apparently, it's controlled by phy, and I haven't found any registers to turn them off
