<rellla> jernej: i used the libreelec repositories to set up mali binaries and the kernel driver. all good so far.
<rellla> i wonder, how i must proceed with https://github.com/LibreELEC/libmali/tree/master/src ?
<rellla> Kwiboo ^^
airwind has quit [Quit: airwind]
<jernej> you should define mali family used
<jernej> for 400, you add -DMALI_VARIANT=400
<rellla> jernej: i manually did, what package.mk said
<rellla> so i have the r7p0 450 blobs from https://github.com/LibreELEC/libmali and the kernel module from https://github.com/LibreELEC/mali-utgard/tree/DX910-SW-99002-r7p0-00rel1 sucessfully installed and loaded.
<jernej> oh, I think libgbm is actually just soft linked to libmali
<rellla> now i want to build kmscube and that fails, because the gbm version is too old. so i found the src directory which includes the right header and a gbm.c file.
<rellla> the commit message says sth about a gbm wrapper which sounds like it is exactly what i am missing. so i wonder how i can do that manually.
<jernej> I don't think that's used
<jernej> at least at the moment
<rellla> Kwiboo might know, because he pushed that?

<montjoie> removing sata made it boot...
<Net147> montjoie: I don't have SATA enabled in my kernel
<Net147> montjoie: 4.19.78 is less than a week old...
<montjoie> now, time to understand why sata break the board
<Net147> montjoie: are you powering using DC connector?
<montjoie> yes
<Net147> not sure. I did try SATA once a few years ago. it worked fine.
<montjoie> I just started to re-enable things and wont boot (even without sata)
<Net147> do you have a bootlog where it gets stuck?
nexgen has quit [Quit: Leaving]
<Net147> perhaps add "ignore_loglevel initcall_debug" to kernel command line?
<montjoie> the fail is random...
<Net147> what distribution?
<montjoie> no distrib, it is a kernelci job (with simple buildroot on ramfs)
<montjoie> but the boot didnt reach init
<Net147> ok...
<montjoie> according to the working boot, it is USB just after the freeze
<Net147> that'sa lot of sun4i-ss errors
<montjoie> totally normal, CRYPTO_EXTRA_TEST is enabled
<Net147> okay. did you try with the ignore_loglevel and initcall_debug?
<montjoie> will try
<montjoie> pff I just remember that I disabled USB in uboot for this board...
<montjoie> related ?
<montjoie> uboot was freezed in starting USB
<Net147> I disable USB too in U-Boot
<KotCzarny> usb in uboot is nice for fixing things up, or multiboot
<KotCzarny> but there are broken usb keyboards that create problems
<montjoie> nothing is connected
<Net147> you can try adding clk_ignore_unused to kernel command line too. in case the kernel is disabling some clock that causes it to freeze...
<montjoie> all recent boots passed withotu USB, I try to reenable it

<libv> https://www.ebay.de/usr/valkir55 is selling dvds with images of apparently mostly sunxi devices
<libv> not that he is making measurable money with it
<libv> but... wtf?
<ullbeking> i just realized why OPi +2E is my favorite, and why it was love at first site.... it doesn't have SATA, and doesn't even attempt to emulate it via USB.
<ullbeking> And it's H3 so well supported

tllim has quit [Client Quit]
<ullbeking> [TheBug]: YES!!! I STILL have to try it!
<ullbeking> maybe it will initialize better than Armbian?
<[TheBug]> or... or... get this, you can Dual load Armbian or even tripple load Libreelec H3 once you installed H3Droid from H3resc ;p
<ullbeking> is H3resc the important word in that sentence?
<ullbeking> ;-)
<[TheBug]> H3resc is pretty sweet for that, as long as you have a decent sized SDcard it is our Bios that allows you to setup the system pretty much and you can dual/tripple load Armbian/Libreelec from right in H3resc
<ullbeking> wow
<ullbeking> ok, i'm setting up a fresh +2e right now
<[TheBug]> provides utilities to resize partitions, copy system to Emmc

<[TheBug]> ullbeking: my and KotCzarny's purchases of the OPi Plus 2E is what spawned the project -- thats why when I saw you talking about the Plus 2E I had to say something :) It is for sure the best H3 device I own and I own at least 11 different H3 boards..
<ullbeking> im so glad that you did say something then!!
<ullbeking> it's still the best one, and stil the one i recommend to others
<[TheBug]> yep, if someone asks its the one I tend to recommend
<[TheBug]> PC Plus is also good in a pinch if you don't mind the lower amount of emmc spaceand half the memory
<ullbeking> it was particularly welcome advice at the time because i was looking around and checking my research for recommendation for a small very quiet home server that is also a vert host, and having people bash my head for my choices was another great introduction to irc at that time.
<ullbeking> so when you and KotCzarny were nice to me i was so happy
<[TheBug]> hehe :)
<ullbeking> i think i have pc plus 2
<ullbeking> what is it about pc plus that you like?
<[TheBug]> well, it isn't that others arn't nice, its just in this niche those with a lot of experience have limited bandwidth available as they are often busy with more important tasks, so I can see how it could be seen as unwelcoming. The reality is you just have to come and ask and be as direct as you can and as people have time they will try to help. I used to feel it was a bit rough sometimes
<[TheBug]> as well in similar channels, but came to understand it isn't the people don't want to, it is just a time restriction. ;)
anarsoul|c has quit [Quit: Connection closed for inactivity]
<[TheBug]> PC Plus is just the dumbed down version of the Plus 2E in my opionion, its basically just half the memory and half the emmc. You do however lose the 4 independantly routed usb channels as I think on the PC Plus it uses a hub, however, in most of my use cases this hasn't been very impactful. For some it could be though, I imagine.
<[TheBug]> but as a general little server box or media box, its just about as productive. You obviously have some gains from higher memory on Plus 2E, like you have to worry less about issue in Android where GPU wants a bunch of memory, cutting down the system usable amount.
<[TheBug]> but in Linux, really you won't see too huge a difference I don't think
<[TheBug]> its not quite as memory hunger by any means

<ullbeking> hey [TheBug]
<ullbeking> i'm working on a poc right now so it's not even confirmed that i'll even need pci-e
<ullbeking> and i'd prefer a design that didn't need it anyway
<ullbeking> but i am designing a small board to interface with a workstation or server type of computer, and has trusted access to the interior bus, etc, of the system itself
gnufan_home has joined #linux-sunxi
<ullbeking> it needs to exercise the level of control it needs on the host system
<ullbeking> but first, as i mentioned,
<ullbeking> it would be great if i didn't have to use the pci-e because it would be much simpler and and much less prone to nuclear level security holes if it isn't done perfectly
<ullbeking> and second,
<ullbeking> it would have to be build on a 100% libre or libre-friendly sbc. we have an rpi 3b+ protoype in development, but i don't really like rpi
<hellsenberg> pcie on sunxi? I thought H6 had useless PCIe?
<ullbeking> no no
<ullbeking> hellsenberg: wait
<ullbeking> i'm not using this opi for that project
<ullbeking> this is for sth else
<hellsenberg> um, then I think I got lost

<aalm> oh, libr:E
<ullbeking> aalm: what does that mean?
<aalm> ullbejing, nvm., =nothing:]
<aalm> err, ullbeking
<aalm> so, what's the big project?
<ullbeking> i wanna shout it from the rooftops but until i, at least, have a very basic bit of code that run and flashes an LED, i am worried that such an announcement would jinx it
<ullbeking> if i had a web page descrinbing it, however, then that would be OK
<aalm> ic
<ullbeking> so I need to describe it on a web page
<sunshavi> ullbeking: opi+2e 4 flashing coreboot. is it smth different from rpi?. Most guides on the net are based on rpi
<ullbeking> sunshavi: the flashing is completely incidendant
<ullbeking> incidental*
<ullbeking> basically i am building a hardware device and writing firmware so that it is able to perform power control, etc, on a remote machine
<ullbeking> so
<ullbeking> it needs to be on a libre SBC or libre-friendly SBC at lkeast
<aalm> power control as in on/off, or via pmic controlling voltages etc. even?
<ullbeking> aalm: it's quite low level
<ullbeking> i.e.,
<ullbeking> it's not just WoL
<ullbeking> also, you see that a device that has such initimate access to your computer needs to be fully auditable
<ullbeking> OK, Armbian is install on the +2E
<ullbeking> maybe it's time for H3Droid now
<aalm> how do you audit a chinese SoC ?
<ullbeking> it may not be a chinese soc
<aalm> i see
<ullbeking> this is another reason i don't like having to explain it on the spot
<ullbeking> i foget details
<ullbeking> and people get confused
