<nasuga> eben: I understand how you feel. Technology has distracted us of what really matters in life (IMO).
nighty has joined #linux-rockchip
<Eben> nasuga: that's right on the money, all I want is something that works, instead I'm stuck with technology
<Eben> ironically, I'm trying to make a piece of technology work....

<nasuga> eben: let me know how 4.8.1 fares for you, I'm currently trying to figure out why my backlight turns off before kernel displays any text
<Eben> nasuga: it's still building, will keep you posted as I go along
<Eben> having said that after the kernel boots I've got to rebuild the entire system, it's quite the mess.... so it might take a while before I've got a real idea of what's working and what is not....
<nasuga> Using the arch install is a good start for figuring out testing kernels, small image and easy install.
<Eben> I've got another sd card with that base arch installed on it
<Eben> I'll flash the new kernel to that once I have this sd card booting
<Eben> if that works I'll flash it to my arch install sd card that's got everything installed on it
<Eben> except my partitioning schemes are different, will have to tweak a little...
<Eben> I'll figure it out...
<nasuga> It's difficult to debug, nothing is being written to dmesg but when booted with debug flag I got this: https://paste.debian.net/hidden/001ba41f
<nasuga> My problem is the kernel boots but screen goes dark with no backlight. No text is visible if I shine a light
<stdint> nashpa, from your log, I didn't see the mali gpu start and screen
nasuga has left #linux-rockchip ["Leaving"]
nasuga has joined #linux-rockchip
<nasuga> stdint, Hmm, I'm almost certain I built mali related modules. I'm rebuilding the kernel, I'll pay more attention to the config
<stdint> did you enable the mali entry in dts?
<stdint> if you use the kernel 4.8, it won't have mali gpu support I think
<nasuga> it asked me during build with oldconfig question, I wrote "y"

paulk-collins has quit [Read error: Connection reset by peer]
<stdint> it can't be, the mainline kernel certainly doesn't have mali support
<stdint> you may mistake it with mali video output
<stdint> it is not gpu
paulk-collins has joined #linux-rockchip
cnxsoft has joined #linux-rockchip
<nasuga> If Mali support isn't in mainline kernel, how can I achieve textmode atleast?
<nasuga> Will I have to resort to old ChromeOS kernel 3.14?
<nasuga> I was under the impression of that 2D rendering was available and 3D with a blob
<Eben> ok vbutil_kernel give me an error, Missing required bootloader file
<nasuga> eben, use --bootloader config.txt
<Eben> what's the contents of config.txt?
<nasuga> replace config.txt with whatever file that contains your boot parameters. In the ccase of --bootloader, it doesn't need to contain anything but must be satisfied as an argument
<Eben> ah so use --bootloader instead of --config
<Eben> gotcha
<nasuga> use both but point both to the same file
<Eben> sweet done
<Eben> that kernel just beeps at me
<nasuga> If it beeps, partitioning is wrong
<nasuga> atleast it was in my case
<nasuga> I have the most success following the Arch installation guide to partition correctly
<Eben> mmm ok I'll give that a whirl....
<nasuga> You need to two partition, one for kernel and one for data.
<nasuga> Checkout section " create a root USB or SD for dual booting"
<Eben> I've got 3
<Eben> u-boot kernel linux data
<Eben> I suspect that I should redo it all....
<nasuga> You only need two
<nasuga> one chromeos kernel partition type and the other linux data
<Eben> ok I'm going to go home and try flashing that kernel to an arch install....
<nasuga> Good luck :)
<Eben> I'll be back online in about 30 mins or so....

<Eben> nasuga: flashed it to the arch sd card and now I just get a black screen when I try to boot
<nasuga> Same issue as me, I found I had a lot of modules not enabled in config. I'm rebuilding right now, I'll let you know how it turns out.
<nasuga> eben: in ncurses config menu, press / and search rockchip
<nasuga> check how many rockchip modules you have selected
<Eben> 2 modules 1 built in
<nasuga> I was missing many, including drm support
<nasuga> If my kernel boots, I'll share config
<Eben> oh wait I didn't scroll down...
<Eben> sweet
<Eben> actually most of mine are enabled
dr1337 has quit [Quit: Page closed]
<Eben> nasuga: any luck on getting that kernel to boot?
<nasuga> Still compiling, I forgot to uncheck some unneeded modules that were also failing to compile
<nasuga> Should be done soon
<Eben> cool
<Eben> I ended up rebuilding gentoo on teh arch parition
<Eben> partition...
<Eben> now I've got gentoo booting with the arch kernel...
<Eben> sub-optimal, once you figure out the kernel I can build a new kernel
<nasuga> I know very little of the linux kernel, I'm surprised you're not having better success ...
<Eben> ah, well I'll give it another crack once I have a fully functioning gentoo system, I've got some more ideas....
<Eben> I just needed to make some progress, 3 days with no progress sucks
<nasuga> I know the feeling. Perhaps the solution will come in a dream :P
<Eben> its happened in the past....
<Eben> solved some gnarly crypto problems like that in the past...
<Eben> reverse engineering job to circumvent a 3rd party vendors crypto....
<nasuga> eben: I'll have to get back to you later, it's late and i40e module is preventing compilation
<Eben> no worries
