IgorPec has joined #linux-sunxi
<_mamalala>
meh ... "something special" to me would be something like an arm based desktop chip/mainboard, preferably with lots of cores ... those chips do exist, but only for servers so far
<KotCzarny>
so you only need cpu power? or bandwidth?
<_mamalala>
i mean, it's rather sad that there is virtually no choice in what architecture to use for a desktop computer nowdays ... after apple has dropped the ppc, there is virtually only x86 left ... pretty boring, imho
<KotCzarny>
(its not the same, because marvel dual core a8 chip leaves ANY allwinner chip in the dust when it comes to data moving/storage
<KotCzarny>
for desktop you need good mhz and probably 2d accel
<KotCzarny>
and ram, lots of ram, 2gb minimum
TheSeven has quit [Ping timeout: 256 seconds]
[7] has joined #linux-sunxi
<_mamalala>
all of which is not an issue with arm ... if just someone could be bothered to implement it for a somehwat decent desktop system
<_mamalala>
and no, i seriously do not not count things like settop-box chips (like the allwinner and similar) to be desktop-capable just because they got some hdmi and usb interface :P
<_mamalala>
otoh, it's rather funny ... the display engine of the allwinner is able to overlay 4 sources at once in hardware, with alpha channel ... something that sounds like a decent thing for desktop use (i mean, how many windows do you move at once?) but somewhat overkill for just a settop box
<_mamalala>
if the sparse specs around can be trusted, that is

Hello. I found an A10 tablet (CUBE U11GT) in my grand parents' home and created a device page for it. I'm sorry I can't test its UART because I don't have soldering tools around. Shall I submit its fex to sunxi-board now?
<_mamalala>
but really ... a nifty 64 bit arm chip with, say, 16 or 32 cores ... having decent pci-e and sata interfaces ... that would be a nice start, i think
<KotCzarny>
mamalala: but cpu processing is crappy, so using it for any modern browser is a bit of pain
<KotCzarny>
i've managed to use opipc as a desktop replacement with firefox working decently
<KotCzarny>
1gb was a bit too little for pages with multiple big images
<KotCzarny>
that's why you need 2gb minimum
<_mamalala>
KotCzarny: browser performance on these small arm boards have exactly nothing to do with the arm itself
<KotCzarny>
then what is your use case?
<_mamalala>
i mean, try to use a firefox with just a vesa compatible vga card and see how performant you will get .... but then, yea, i know, modern x86 don't allow stuff that low ...
<KotCzarny>
nah, its not the video engine slowness, single core performance matters, and 1.2ghz of allwinner is puny
<_mamalala>
the issue with that kind of stuff is not the core itself, but the external bus it can use ... so, that is why i said pci-e and sata natively implemented ... so that one can plug in a half-decent graphics card and fast storage
<_mamalala>
1.2 ghz on any chip is "puny" if you basically jail it with half-arsed, slow interfaces to the world ...
<_mamalala>
i mean, these chips _are_ made for things like settop booxes, which have a completely different use-case than desktops ... the core itself can't do much without decent peripherials
<_mamalala>
like, the H3 can do hardware video decoding of full hd streams just fine ... but it craps out at compositing just a simple window to move around ... simply because it lacks the proper interfaces for that stuff (in this case, something like a pci-e to a decent graphics card to do the compositing)
<KotCzarny>
but then again, if you want to plug some monstrosities into it, just grab i5 based laptop, as arm has a long way to go
<KotCzarny>
that's the price of energy efficiency
<KotCzarny>
remember intel atoms? they were as crappy as arm chips
<_mamalala>
arm chips are't really crappy ... simply because there are no "arm chips"
<_mamalala>
just chips that implemet some arm ip in one way or another
<KotCzarny>
s/arm chips/currently available arm implementations/
<_mamalala>
as said, you can have decent server boards with arm cores, very performant

Hello Everybody. I'm trying to get a kernel compiled for my OrangePi PC.
JohnDoe_71Rus has quit [Remote host closed the connection]
<plaes>
miasma: it only happens when you have certain debugging option enabled
<Saurabh>
miasma: Oh yeah, read all about the 4.8 issue. Would you tell me what defconfig would work for the opi pc with 4.8? I'll just turn off that particular config option which is causing all the furore about 4.8.
<miasma>
Saurabh: i use the kernel.org kernel with opi pc
<Saurabh>
I have a board with the A20 on it. A custom board. I'm using that ugly sunxi 3.4 kernel on it right now.
<Saurabh>
If I move to mainline, what do I lose? What exactly does drm graphics support mean anyway? Isn't X running on top of the framebuffer anyway on these chips?
<plaes>
Saurabh: no drm yet for A20
<Saurabh>
miasma: Send me your kernel .config, would you buddy.
<plaes>
though... it you have RGB LCD, it would be possible to get it working
<Saurabh>
I use VGA and HDMI. I understand drm does kernel modesetting. What else does it do?
<plaes>
well, not much
<plaes>
no support for VGA and HDMI
<miasma>
Saurabh: this might not have everything you need, maybe even some wrong options, but it should boot and provide a starting point http://users.utu.fi/jmjmak/tmp/config-48-opipc
ricardocrudo has quit [Remote host closed the connection]
<Saurabh>
miasma: Starting point is fine man. I'll wing it from there.
<Saurabh>
So, does kernel 4.8 give us drm on the H3?
<Saurabh>
miasma: does your opi pc HDMI display work with this kernel config?
matthias_bgg has quit [Ping timeout: 252 seconds]
<KotCzarny>
my banana pi m1 (a20) works with mainline and hdmi
<miasma>
Saurabh: i use it as a headless server
<miasma>
so, no
<KotCzarny>
but not using legacy kernel means there is no g2d support, so X is SLOW
<KotCzarny>
i have to change resolution to 640x480 or similar to be able to watch videos (i dont use cedrus, just software decoding)
<miasma>
you should blame allwinner and arm holdings
<Saurabh>
Thanks KotCzarny
<KotCzarny>
in short, uboot sets simplefb and kernel just uses that
<Saurabh>
miasma: I shall also blame myself. The kernel isn't going to write itself. Maybe I should start poking into the A20 drm code.
<Saurabh>
Thanks guys. This is what I needed to know. Gotta sign off now. Midnight here.

orangepi pc will be supported after mainline kernel 4.9 right?

is there a timeline for it
<KotCzarny>
no timeline, only patches
<KotCzarny>
and there is high chance few things wouldn't even land in 4.10
sarietta has quit []
<apritzel>
miasma: slightly biased here ;-), but this stuff is not about Mali, isn't it? So why blaming ARM holdings?
<nikre>
is there a cheap but same broadcom board like raspberry v3?
<KotCzarny>
opipc
<KotCzarny>
;)
<KotCzarny>
or pine64
<apritzel>
nikre: who wants that?
<KotCzarny>
unless you ask about broadcom blobware boards?
<nikre>
just wondering
<apritzel>
nikre: not that I know of, no
<KotCzarny>
afair rpi foundation specifically bounds broadcom to be sole maker
<apritzel>
there were only some BCM2835 board, but I am not aware of anything later not from Rpi foundation
<KotCzarny>
there were few clones though
<apritzel>
the BCM2837 is seriously broken
<apritzel>
it's just attractive because of that fruit
<nikre>
it is on mainline kernel right?
<apritzel>
kind of
<apritzel>
the official RPi Kernel is not mainline, though
<apritzel>
and I think has never been
<apritzel>
they are keeping their crap in parallel to the upstream stuff
<nikre>
are there other communities like there is for allwinner?
<KotCzarny>
surely
<miasma>
apritzel: i don't know the details that well, but my impression is that Mali drivers would play a role in drm/kms support for boards using mali blocks. e.g. h3
<KotCzarny>
there are also rockchip and marvel ones i think
<apritzel>
miasma: I am not an expert, either, but display is independent from GPU (which is Mali)
<nikre>
do those brands provide open source?
<KotCzarny>
allwinner doesnt provide much open source
<apritzel>
nikre: better than Rpi and AW, at least
<apritzel>
At least I see a lot of Marvell and RK code in the kernel
<miasma>
apritzel: yes, the signal paths probably are, but if you had free mali drivers from arm holdings, there would be more incentive for allwinner etc. to support them too
<apritzel>
even this Espressobin SoC seems to be fully supported already
gianMOD has joined #linux-sunxi
<nikre>
i get the impression that marvell is a more professional company, is that right?
<miasma>
why do they (espressobin folks) mention kernel 4.4. then? wouldn't the next lts kernel be ready before they ship
<KotCzarny>
maybe because its what they started fiddling with
<KotCzarny>
and didnt rebase since project start?
<miasma>
4.11 might be ready when the people get their 1GB espressobin
<apritzel>
I wonder why a vendor should care about a particular kernel in the first place, this is actually something the distributions take care of
<apritzel>
if you are upstream, that is ;-)
<miasma>
i bought the x86 based up board some time ago from kickstarter. they still haven't got hdmi audio support and i'm not sure about the board specific stuff either. like gpio
<miasma>
they maintain their old outdated kernels
<miasma>
it's funny how intel forgot to support their mobile platforms (cherry trail)
<miasma>
no audio, broken power saving modes, no gpio support. mkay
<miasma>
the board needs a relatively large heatsink AND a fan. otherwise it will hang in a day
<KotCzarny>
arm is the way for really low power chips
<KotCzarny>
otherwise just grab i3/i7
<KotCzarny>
(there is also mips for alternative)
<miasma>
yea, the cherry trail is pretty disappointing. it can barely run a browser. i couldn't get gpu support for video so the machine is working almost 100% when playing a youtube video in a browser
menomc is now known as mnemoc
<miasma>
the javascript is also killing it
<miasma>
gpu decoding works in kodi and other software, but not in firefox
<miasma>
or maybe it's supported but combining the video surfaces or something is done on software in firefox, which slows it down

I think I need a good talking-to about GPIO configuration in the fex file. If a device (in this case, a ctp) is configured to use two GPIOs in the fex file (ctp_wakeup and ctp_int), do I still need to list those same two GPIOs in the [gpio_para] section?

Originally I didn't have a [gpio_para] section at all, and it looked like there were no exported GPIOs at all, and ctp driver couldn't start, probably because of that. I think.
