hyrcanushello03:48
c0rneliushey03:49
hyrcanusgreetings c0rnelius03:50
c0rneliusditto03:50
hyrcanuswhy aren't there linux arm SBCs with cortex cpus newer than A73?04:12
gnarfacenot a lot of commercial demand for these things yet04:13
gnarfacenot running linux, anyway04:13
hyrcanusanyone here gotten devuan-arm running on the google pixel-c tablet?04:16
hyrcanuswith keyboard, FOSS drivers, strong GPU, almost a nice subnotebook possible04:16
c0rneliusI would think not as its some what proprietary and Android kernels tend to be way behind the curb and in them selves super vendor driven.04:20
gnarfaceyou should check out the pinebook pro04:21
gnarfaceprobably not faster than a google pixel-c but probably better supported04:21
gnarfaceyea the problem with trying to repurpose android devices is that their kernel is freaking ancient now04:22
c0rneliusWell with the Pinebook ur either looking at an allwinner or rockchip SoC.04:22
gnarfacethe rockchip ones are the faster ones04:22
gnarfacethey only put those in the pro04:22
c0rneliusYeah it uses an RK339904:22
gnarfacethe older pinebooks are A64 but also discontinued04:22
c0rneliusA64 also sucks. No offense :)04:23
c0rneliusIts a juiced up H5, which is also now discontinued.04:23
gnarfaceit's an objectively crappy chip by modern standards but that also makes it completely immune to all the hardware-instruction-level vulnerabilities of newer cpus...04:23
hyrcanushttps://github.com/pixelc-linux04:24
c0rneliusI meant more in practical terms. I have an a64 board. Its pretty bad.04:24
c0rneliusThe H5s actually seemt o run better.04:24
hyrcanusthe speculative execution vulnerabilities are terrible04:25
hyrcanusbut so are websites, which require supercomputers to display some text and graphics04:25
c0rneliusI mean next week this will be some how outdated as we are dealing in the world of Arm, but for pure horse power I would probs go with a S922X Amlogic SoC.04:27
c0rneliusRuns cooler than RK3399s for starters and the BIG little is switched up, making it an over all faster SoC.04:28
c0rneliusPLus its clocks higher04:29
gnarfacedo we have a devuan image for that yet?04:31
c0rneliusOfficially no. But I can make them.04:36
c0rneliusI added support for Devuan here, but I haven't run tests on everything - https://github.com/pyavitz/debian-image-builder04:37
c0rneliusBeen busy trying to work out the defconfigs for 5.14.y and above. I think Tenkawa has made some Devuan imgs and tells me they work? I can't be completely sure though.04:39
c0rneliusI think the only init I haven't made for it was fan control, but tobetter who does the kernel source for hardkernel and the odroidn2+ provides an overlay for it. So in theory I really shouldn't have too. But I haven't tested that yet.04:47
c0rneliusRun like a beast though. So I don't see why if we didn't make a small effort we couldn't provide imgs.04:54
c0rneliusCPU Temp:  35°C 37°C04:54
c0rneliusCores:     1908000 1908000 2208000 2208000 2208000 220800004:54
c0rneliusGovernor:  performance04:54
c0rneliusUptime:    22:53:22 up 13:33, 0 users, load average: 0.00, 0.00, 0.0004:54
c0rneliusAnd thats me using it slightly under clocked on 5.14.704:54
steevc0rnelius: thanks for the growpart recommendation the other day, that is indeed working for me05:12
c0rneliussteev: You are very welcome.05:19
hyrcanusc0rnelius: khadas vim3 here.  it's pretty good.  i could use 6GB with browser running though.05:37
hyrcanusthe web is horrible, horrible05:38
hyrcanusand the open-source panfrost drivers work quite well for those amlogics now05:39
hyrcanusopengl + opengl-es on cheap arm boards.  it's really nice.05:39
hyrcanusunfortunately the gpus on the amlogics are mali G52 mp4.  Very weak for pixel shaders.  Nvidia's jetson nano crushes it05:40
hyrcanusmediatek's new silicon is also crippled in the shader dept..  the claim to target notebooks but deliver phone -level power envelope05:41
hyrcanusso if you're running any gl/gles stuff, that Pixel-C still is best, by far05:42
hyrcanusand you get open-source drivers, no blobs05:42
hyrcanusif you can piece it all together, that is05:43
hyrcanusonly a few people have done it05:43
c0rneliusI don't have a lot of faith in running any of these boards as main driver / desktop. I use them all mostly headless, if not I use it as niche devices using Core/LibreELEC if I want good vid playback.05:43
hyrcanusi'm fine with 1080p tbh05:44
hyrcanusbut yes graphics has been horrible in arm world.  it's very nice nvidia recently delivered open-source drivers, and that panfrost has working drivers05:45
hyrcanusso there is progress05:45
c0rneliusFor me its more of a... Sure it could be done? By why bother? You can go a buy a used thinkpad off ebay and do better for ur self with less effort.05:45
hyrcanusthinkpad doesn't fit in pocket :)05:46
c0rneliusEither does my N2+05:46
c0rneliusor my NanoPC-T405:46
c0rneliusor any of my tablets05:46
hyrcanusmy khadas fits in coat pocket, so i take that with me05:46
c0rneliusDon't have a khadas so I won't try to speak for them. But the form factor doesn't seem all that diff than other boards for the most part.05:48
hyrcanusnothing against thinkpads :) i have many05:48
c0rneliusBut yeah, I don't know.05:48
hyrcanusi feel better without Evil Inside™05:49
c0rneliusI think people expect to much from these SBCs, but I believe I'm apart of the "Not trying hard enough crowd to make this do what the world wants it too" group. I could be wrong?05:50
hyrcanusit's all I use since three years05:51
c0rneliusHey I use them everywhere. Just for certain things.05:51
c0rneliusI don't expect them to solve all my problems. But I don't expect this one to do that and another to do this and blah blah.05:51
c0rneliusIts niche05:52
c0rneliusI have two setup as kodi boxes, another two embedded in speaker cabs for bluetooth and audio playback from services. Another one runs weechat, whilst another runs a webserver. Its just about focus for me I suppose. But I never expect one to accomplish all these goals.05:53
c0rneliusThe more powerful ones I use for kernel compilation and img building for all the others. Basically development.05:55
c0rneliusThen we have all the stupid Pi's which are fun. I have one as a clock on my desk and 6 running as cams. Another as security display in kiosk mode so I can watch stupid happen live. SO yeah there is endless amounts of things we can do... Retropies are also fun L(05:58
c0rnelius:)05:58
hyrcanusever get neural nets running on them?06:00
c0rneliusCan't say I have, no.06:00
hyrcanusi haven't either.  python wheels and broken python*06:01
c0rneliusPython is kind of busted in Bullseye right  now.06:01
c0rneliusStill works in Focal alright. But its... Focal. But yeah.06:02
c0rneliusI had an old python setup for making them into Bluetooth Audio Receivers, then Bullseye happened and its completely broke. I decided to look into Focal and yeap, still works there.06:04
hyrcanuswhat do you use for amplifier?06:10
hyrcanusi use a direct digital amplifier06:15
hyrcanuswith electro-planar speakers, it is very revealing06:15
steevi like my c630 :(06:23
steevdefinitely won't fit in the pocket, and won't win a ton of speed awards, but storagewise, it does run circles around anything using usb/emmc/sdcard06:24
c0rneliushyrcanus: https://github.com/pyavitz/musicbox07:34
c0rneliusBut as suggested this should work on just about any SoC - https://github.com/pyavitz/musicbox/commit/fd5120e01072e2456f80789e0399a979da4302e5#comments07:35
hyrcanusnice project07:35
c0rneliusYou may need a ground loop though depending on the board an amp module.07:35
hyrcanusatm i just run a usb line to my amp07:36
c0rneliusI have another self powered lil amp module but I recall the model off the top of my head? I just know that one doesn't require a ground loop.07:39
c0rneliusI can't*07:40
hyrcanusi thought ground loop was when you got the annoying sound from improper grounding07:40
c0rneliusWell that and it prevents annoying clicking which most boards tend to have from the analog port.07:41
hyrcanushm07:42
c0rneliusPi's and allwinner boards especially in my testing07:42
c0rneliusThats not to say I'm 100% correct on that. Its just something I've noticed on some boards.07:43
hyrcanusyes often when the fix/workaround is found, it's a waste to delve further into root causes07:44
c0rneliusExactly.07:45
c0rneliusPlus they don't cost much.07:46
c0rneliusAnd those PAM8403s modules cost even less.07:46
c0rneliusNice thing about 8403 is you can power it from the 3V pin on the board and ground it as well. Its pretty sweet.07:50
c0rneliusLoud too.07:50
c0rneliusJust solder on the header pins and ur ready to rock.07:51
hyrcanusthing about my digital amp is it's not got the oomph, so i want to biamp with an adcom driving the woofers07:52
