19:52 <phariseo> hello everybody

19:53 <phariseo> is 3.16rc-6 working on XE303C12...? I compiled it, and when I tried to boot, some stuff appeared on screen (two penguins, quickly scrolling text) and then bam, screen goes off

19:53 <phariseo> even when I don't specify root filesystem, so it isn't rootfs/backlight setting issue

20:27 <Wizzup> hi phariseo

20:28 <Wizzup> I have it working, yes

20:28 <Wizzup> or, well

20:28 <Wizzup> that is on a diff machine, but steps may be similar

20:29 <Wizzup> http://linux-exynos.org/wiki/User:Wizzup/XE503C32/Mainline_Kernel

20:46 <sjoerd> that's quite a different machine

20:53 <Wizzup> yes, I also have an XE303C12 next to me that booted mainline some time ago

20:53 <Wizzup> on 3.14 or so

20:53 <Wizzup> but that was with simplefb still

21:04 <phariseo> hmm

21:05 <phariseo> so maybe I should try 3.14, hmm

21:05 <phariseo> thanks for a link

21:05 <phariseo> I'll compile 3.14 and check out if it boots

21:09 <Wizzup> phariseo: I think generally 3.16 is a much better idea.

21:09 <Wizzup> Can you give more info about what is going wrong?

21:09 <Wizzup> Perhaps use printk delay?

21:09 <phariseo> of course I can :-)

21:09 <phariseo> hmm, is it some kind of bootarg...?

21:09 <Wizzup> CONFIG_BOOT_PRINTK_DELAY

21:09 <phariseo> aha, OK

21:10 <phariseo> I'll compile with it in a moment

21:10 <phariseo> what does it do...? slows down output?

21:10 <Wizzup> yes, you can add a delay *per* printk I believe

21:10 <Wizzup> for easy note/photo taking

21:10 <phariseo> nice! didn't know about that one!

21:10 <Wizzup> but what if it cannot find the rootfs regardless?

21:10 <Wizzup> That may explain failure

21:10 <phariseo> hmm, perhaps it cans!

21:11 <phariseo> BUT, even if I give it rootfs

21:11 <Wizzup> (as in, you stated that you also made it "unable to find the rootfs"

21:11 <phariseo> same happens

21:11 <Wizzup> Try passing rootfstype=ext4 rootwait=30 root=/dev/bla ?

21:11 <phariseo> hmm, but should screen totally turn off because of lack od rootfs?

21:11 <Wizzup> if it panics, then that is possible

21:11 <phariseo> hm, that may explain it, hmm

21:12 <phariseo> so now I'm going to add this printk delay feature, and also rootwait

21:12 <Wizzup> maybe start with rootwait

21:12 <Wizzup> (and rootfstype - that is needed for rootwait)

21:13 <Wizzup> [ 0.000000] Kernel command line: console=tty1 debug earlyprintk rw rootdelay=10 rootwait rootfstype=ext4 root=/dev/mmcblk1p3

21:13 <Wizzup> this is mine

21:13 <phariseo> aha, OK, will flash uboot in a moment

21:13 <phariseo> chromebook is my main computer now, actually :D

21:14 <phariseo> so I made images of uboot and boot partition in chromeos, to quickly recover it

21:14 <phariseo> if kernel doesn't boot

21:15 <phariseo> AGAIN, haha :_)

21:15 <phariseo> * :-)

21:16 <Wizzup> I just type in something in u-boot

21:16 <Wizzup> ext2load mmc 0:2 ${loadaddr} /vmlinux.uimg (or vmlinux-mainline.uimg)

21:17 <phariseo> hmm, ok, will come back there in half and hour and report what my research gave :D

21:18 <Wizzup> I may be asleep by then, but, good luck

21:18 <Wizzup> I am planning on waking up again tomorrow ;-)

21:23 <phariseo> haha, ok :D

21:24 <phariseo> have a good night too, see you tomorrow :D
