01:32 <tparys> evening all

06:27 <[TheBug]> wooohoo givin that rk3399 a run for it's money: https://prnt.sc/119fcxw

06:36 <buZz> load just 5

06:36 <buZz> pff, try harder :P

06:40 <kprasadvnsi[m]> How is the mediatek mt8183 compared to rk3399?

07:05 <b3n10> hey guys, i'm trying to compile kernel to include `gpio_sunxi` module, but on my first try, it is still not enabled saying `Module gpio-sunxi not found`.

07:05 <b3n10> how can i add gpio-sunxi when compiling armbian kernel?

08:19 <kprasadvnsi[m]> I am having a strange problem.

08:22 <kprasadvnsi[m]> I have a TV box with Android and I wanna access the u-boot command prompt but they set the delay to zero so it never give me chance to interrupt the boot process.

08:22 <b3n10> okay i found out i need to compile kernel with `CONFIG_GPIO_SUNXI=y`, where do i put this line?

08:22 <kprasadvnsi[m]> Anybody know other way to solve this problem

08:24 <kprasadvnsi[m]> <b3n10 "okay i found out i need to compi"> Start the build script with KERNEL_CONFIGURE=yes

08:26 <b3n10> i see, will do that now, thanks

09:55 <b3n10> okay, i can't find it in kernel configuration dialog. i see GPIO drivers, but my new config doesn't include `CONFIG_GPIO_SUNXI` option

10:09 <kprasadvnsi[m]> Press the / key and search the config you want

10:33 <b3n10> yep, searched it and can see GPIO drivers and they are already enabled (has a *). so i exit and it starts compiling

10:35 <Xogium> for what its woeth if it has * it means *built-in* not built as a module you can insert with modprobe

10:35 <Xogium> *worth

10:36 <Xogium> aka, its already in and loaded

10:37 <b3n10> i've installed them now on my image but doing `modprobe gpio-sunxi` still says "Module gpio-sunxi not found ..."

10:37 <Xogium> look what I said above

10:38 <b3n10> "aka, its already in and loaded" so no need to do a modprobe?

10:38 <Xogium> exactly

10:38 <Xogium> its not a module

10:38 <Xogium> you built this right into the kernel itself

10:39 <Xogium> if you had pressed m instead of y to enable it, it would have show <m>

10:39 <Xogium> which would mean a module

10:40 <b3n10> hmmm, my purpose is to use power button and to test if it's responding to acpi events, i use 'acpi_listen' command .. but no result when pressing power key .. after doing research, it looks like gpio sunix needs to be enable, that's why i'm compiling the kernel with that module

10:41 <Xogium> was it enabled before though or did you have to go and enable it yourself ?

10:41 <Xogium> aka, did you have to make that * show up ?

10:41 <b3n10> no, * is already there

10:41 <Xogium> so then your rebuild is probably useless

10:42 <Xogium> if it was already in the config

10:42 <Xogium> I'd check the config of a running system with the official armbian kernel

10:42 <b3n10> lsmod ?

10:43 <Xogium> for example use zgrep to check for GPIO_SUNXI in /proc/config.gz

10:43 <Xogium> or possibly the config is in /boot

10:43 <Xogium> no its built-in, remember. Its not a kernel module

10:45 <Xogium> also are you sure its acpi signal ? Afaik, acpi is not used on arm

10:45 <Xogium> or if it is, I've never seen boards using it just yet

10:45 <b3n10> cat /proc/config.gz | gunzip | grep -i "gpio_sunxi" --> returns nothing, this is on my other image which i downloaded from website

10:46 <Xogium> I'd use zgrep

10:46 <Xogium> like

10:47 <b3n10> here is what i was following --> http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=2460

10:47 <Xogium> zgrep GPIO_SUNXI /proc/config.gz

10:47 <Xogium> that allows to use grep on a gzip compressed file directly

10:48 <Xogium> just to make absolutely sure

10:48 <Xogium> but if you don't have this at all in your kernel config it is strange. You should have at the very least a line like: # CONFIG_GPIO_SUNXI is not set

10:49 <Xogium> at best CONFIG_GPIO_SUNXI=y OR =m

10:49 <b3n10> yep, same no result .. i also use `zcat /proc/config.gz | less` then search for the word

10:49 <Xogium> and are you sure that its really the config option ?

10:50 <Xogium> that is, if you press the ? in the kernel config when you are on the sunxi gpio driver or whatever option, is it really GPIO_SUNXI ?

10:51 <b3n10> well i didn't see exact sunxi gpio .. but there is gpio driver support option .. i tried searching for "gpio_sunxi" but nothing

10:52 <Xogium> that sounds like something that is specific to the vendor kernel

10:52 <Xogium> armbian probably uses mainline kernel, so you don't have it

10:52 <b3n10> i also tried searching "gpio" and just scroll to see which of them includes "sunxi" but nothing

10:52 <Xogium> or at least not under that name

10:53 <b3n10> my purpose is just to really use power button to call the shutdown command, instead of pulling the plug just to turn off my board

10:53 <Xogium> you might need to use the vendor kernel if you want that button

10:54 <b3n10> huh? so armbian image is not vendor?

10:54 <Xogium> well

10:54 <Xogium> what does uname -a command says ?

10:54 <b3n10> the one from here - https://www.armbian.com/orange-pi-lite/

10:56 <Xogium> hah

10:56 <Xogium> Armbian Buster

10:56 <Xogium> mainline based kernel 5.10.y

10:57 <Xogium> that answers this

10:57 <b3n10> uname -a --> Linux orangepilite 5.10.21-sunxi #21.02.3 SMP Mon Mar 8 00:23:04 UTC 2021 armv71 armv71 armv71 GNU/Linux

10:57 <b3n10> oh i'm using Focal

10:57 <Xogium> so, nop. Definitely not vendor

10:57 <Xogium> its also mainline, look on the page you sent me

10:58 <b3n10> "mainline based kernel 5.10.y"

10:58 <Xogium> which defintely explains why you don't have this gpio_sunxi

11:00 <Xogium> https://linux-sunxi.org/GPIO

11:00 <Xogium> looks like I was right, there are some ways to acces gpio in mainline but that's definitely not at all like you do in that old 3.4 vendor kernel

11:04 <b3n10> do i need to find a new image or just the kernel that has gpio_sunxi?

11:05 <Xogium> well I'd stick to mainline

11:05 <Xogium> 3.4 kernel is very, very, very old by now

11:06 <Xogium> I'd use the 2nd way of using gpio in mainline

11:06 <b3n10> on the page u sent, on "What do you need:" section, it says "Kernel with CONFIG_GPIO_SUNXI=y .." so that's what i'm missing

11:06 <Xogium> since sysfs is deprecated

11:06 <Xogium> no that's on a 3.4 kernel

11:06 <Xogium> they show examples but only for 3.4 kernel

11:07 <b3n10> ah i see

11:08 <b3n10> sorry, what u mean by "I'd use the 2nd way of using gpio in mainline"

11:08 <Xogium> sysfs way is deprecated,, look up the 2nd one

11:08 <Xogium> accessing the gpio pins through character devices with mainline kernel

11:12 <b3n10> will take a look

11:13 <Xogium> as for how to port this whole shutdown idea… I don't know how, sorry :S

11:13 <Xogium> I've never used gpio on orange pi boards

11:14 <Xogium> but maybe peeps here have ideas for that

11:15 <b3n10> don't have enough time for this today, but i appreciate your time explaining this things for me

11:19 <Xogium> no problem :)

11:19 <Xogium> wish I could have been more helpful but heh

11:24 <b3n10> yes, you helped me a lot here .. i was going on circles on this kernel compilation until u point me to the right page

11:24 <b3n10> bye now, cheers

19:18 <tparys> hi all
