<Tenkawa> greetings all
<Wizzup> hi
<Tenkawa> time for some more kernel fighting this morning
<Wizzup> what device do you have again?
<Tenkawa> chromebook 1 xe303c12
<Wizzup> snow
<Wizzup> I have mainline + some patches working on my snow at least
<Tenkawa> I've got 3.8.11 kernel's in 500 different varieties signed and working
<Tenkawa> yep snow
<Wizzup> Ah, chromeos
<Tenkawa> I'd be happy with a newer chromeos tree kernel
<Tenkawa> 3.8 is just ancient
<Tenkawa> and my 3.18 mainline attempts have been miserable failures
<Tenkawa> it boots however I get no video output
<Wizzup> if you ping me in ~6 hours I can see if I can send you my kernel / steps
<Wizzup> For snow
<Tenkawa> thanks. I'll definitely try to d that
<Tenkawa> Wizzup: if there is a way to self sign and "not" use nv-uboot I'd prefer that
James_T has joined #linux-exynos
<Tenkawa> I've been signing all of my kernels and using standard boot procs
<Wizzup> well, you can do that if you prefer
<Wizzup> kernel stuff is similar
<Wizzup> I use nv-uboot though, for the record
<Tenkawa> yeah most people do..
<Tenkawa> I just figure if the signing is working why not use it
<Tenkawa> my goal today is to trim what I dont need out of my config
<Tenkawa> "slowly"
<Wizzup> I always start with the simplest ways: get to a point where it works, then complicate it
<Wizzup> and signing is a complication
<Wizzup> ;)
<Tenkawa> oh... for me its all scripted to where the signing validates it all went ok
<Tenkawa> I just really dont like being stuck on such an old tree
<Tenkawa> especially with this being my main development box
<Tenkawa> I use it for all of my other arm devel work
<Tenkawa> heheh
<Tenkawa> mind you most of my work is on rpi's
<Tenkawa> and beaglebone;s
<Tenkawa> I still think that arm has so much potential that we havent even hit yet

<Tenkawa> lets see if the 3.14 branch works
<Tenkawa> heheh
<javier__> Tenkawa: the chromeos-3.14 branch on Snow?
<Tenkawa> javier__: yeah
<javier__> Tenkawa: that won't work
<Tenkawa> was afk
<Tenkawa> oh why not?
<Tenkawa> darn
<Tenkawa> is there one specific thing that breaks it?
<javier__> Tenkawa: none of the platform support from 3.8 is in the other branches
<javier__> Tenkawa: so what you will have is the mainline support that was in 3.14 which is almost nothing
<Tenkawa> well darn
<javier__> Tenkawa: if your goal is to use a newer kernel then linux-next + some posted patches is your only option
<Tenkawa> I just need to say forget their src completely and get mainline 3.18 working however I really don't want to use nv-uboot
Nemykal has joined #linux-exynos
<Tenkawa> oh?
<Tenkawa> missed that branch completely
<Tenkawa> let me go do some investigating
<javier__> Tenkawa: you don't need nv-uboot, although is more convenient imho
<Tenkawa> oh..
<Tenkawa> I thought I read I "had" to use it because of the fb if I wanted to use mainline
<javier__> Tenkawa: no, you need to use it if you want to use simplefb so the kernel uses the framebuffer setup by the bootloader
<javier__> Tenkawa: but linux-next already have the patches that adds proper kms/drm support for Snow
<Tenkawa> ok
<Tenkawa> I'm looking in linux-next now
<Tenkawa> which tag should I use
<Tenkawa> they appear to almost/match up with the non-next one
<Tenkawa> at least from just browsing
<Tenkawa> chromiumos/third_party/kernel-next says dead on the chromium git descrips
<javier__> Tenkawa: I meant git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
<Tenkawa> AHHHH
<javier__> display and wifi support for Snow are not in 3.19 but are in linux-next
<Tenkawa> oh thats better
<Tenkawa> nice
<Tenkawa> thank you
<javier__> w /9
<javier__> np
<Tenkawa> now time for clone and reconfig again
<Tenkawa> haahaaahaa
<Tenkawa> javier__: is there a good defconfig or do I have to get in there and piece it together?
<Tenkawa> if theres a defconfig I'll start there and tweak as I go
<Tenkawa> my checkout is almost done
<Tenkawa> er clonw rather
<Tenkawa> er clone
* Tenkawa notes this brings back memory of his first kernel builds back in 1994
<Tenkawa> heheheheh
<Tenkawa> oh an devicetree..
<Tenkawa> which dts should I use?
<Tenkawa> nm found it
<Wizzup> find arch/arm/boot/ | grep snow ;-)
<Tenkawa> Wizzup: some of the trees had multiple snow versions
<Tenkawa> this one did not fortunately
<javier__> Tenkawa: exynos_defconfig should be a starting point but it does not have HDMI and the needed options for wifi enabled
<Tenkawa> s/versions/revisions rather
<Wizzup> Tenkawa: the chromeos ones had yeah
<Tenkawa> javier__: thats ok .. I'll add those in a piece at a time
<Tenkawa> I just want to get a baseline working then tune
<Tenkawa> i have some usb wireless cards to use if needed too
<Tenkawa> its compiling.. .now I wait
javier_ has joined #linux-exynos
<Tenkawa> this old cb1 still is pretty speed for compiling..

<Tenkawa> it boots...
<Tenkawa> blinks and no output though
<Tenkawa> the video output to the console has been my problem
<Tenkawa> am I possibly passing it the wrong console=?

<Tenkawa> javier_: hey did you see my last msgs about the testing/
<Tenkawa> er ?
<Tenkawa> brb though... testing one more thing
Tenkawa has quit [Quit: leaving]
Tenkawa has joined #linux-exynos
<Tenkawa> yeah.. just cannot get it to output to the internal display... seems to be fine otherwise
<Tenkawa> doesnt appear to be able to find any video hardware
<Tenkawa> brb.. going to cleanup some logs and get some data

<si1v3r> Linux-next booted on my peachpit with no tweakage at all.
<Tenkawa> can you post me your /proc/cmdline?
<Tenkawa> are you using simplefb nv-uboot?
<Tenkawa> I'm trying to avoid nv-ubooot
<Tenkawa> well darn...
<Tenkawa> si1v3r: any theories?
<si1v3r> Uh, I'm pretty sure simplefb is not required or desired anymore
<si1v3r> Since this latest kernel is supposed to have exynos drm code merged in
<Tenkawa> hmmm
<Tenkawa> ok trying a diff tweak
<Tenkawa> si1v3r: oh..... i just noticed you said peachpit
<Tenkawa> i'm on snow
<si1v3r> Snow should work even better
<Tenkawa> I wonder if the devicetree needs a tweaj
<Tenkawa> it definitely seems to know its there
<Tenkawa> it just doesnt seem to direct the output properly
<si1v3r> I've been using nvuboot so I can do tweaks easier.
<Tenkawa> let me plug up my hdmi port and see if thats where it might be ahoving it
<Tenkawa> er shoving
