06:00 <zenmetsu> Wizzup, I'm rebuilding gentoo on my arm chromebook and it's been quite a while, much appears to have changed. Are you still running gentoo on yours?

06:29 <Wizzup> Yes

06:29 <Wizzup> What appears to have changed / what can I help with

06:37 <zenmetsu> well, trying to figure out why i have no /dev/mali0 for instance

06:37 <zenmetsu> is that kernel source, or is there a driver that i have to grab from somewhere

06:38 <zenmetsu> pretty hard to find up to date documentation on the build, everyone seems to be running pre-canned *buntu variants :(

06:44 <Wizzup> I never used mali

06:44 <Wizzup> It is indeed in the kernel, and it may be in some close-to-mainstream kernels like the one liquidacid has, which I think tracks the odroid one, but I am not sure

06:45 <Wizzup> but aside from the kernel interface you also need the binary userspace blob

06:45 <Wizzup> and you don't get opengl, only opengles

06:45 <zenmetsu> yeah, the userspace blob i can figure out. just trying to get the kernel part nailed down. I kinda want hw acceleration

06:47 <zenmetsu> i'll poke around some more i suppose. i haven't had luck finding a kernel tree that had the driver included. i'll look at the liquidacid kernel and see if it helps out. thanks :)

06:51 <Wizzup> https://github.com/tobiasjakobi/linux-odroid-public

06:51 <Wizzup> I don't know where he syncs to/from, what his intensions are. Maybe wait for someone who does use mali

06:57 <zenmetsu> i'm cloning that repo now. it looks like it will work.

07:16 <zenmetsu> bah, looks like i'll have to wait for someone that knows about the mali setup. That kernel only has the 3xx and 4xx mali devices, not the 6xx that's in this chromebook

07:25 <steev> zenmetsu: that kernel is for the odroid devices; if you want mali, you'll need to use the cros kernel

07:25 <steev> ftr though, the config he uses is here https://raw.githubusercontent.com/tobiasjakobi/odroid-environment/master/sourcecode/system/vanilla-4.6-debug.conf

07:26 <zenmetsu> well, this is the chromebook 2 (xe503c32) which uses the same mali T628 as the odroid XU3/XU4

07:28 <steev> yeah that's for the U3 though, iirc

07:28 <steev> or at least, that's what he uses it on

07:30 <steev> it's definitely exynos4 related (his kernel config doesn't enable exynos5)

07:33 <zenmetsu> it seems as if I'm doing something fundamentally stupid :/ trying to figure out how the odroid boards using this GPU are getting HW support

07:55 <krzk> zenmetsu, which odroid? Different exynos SoCs had different Mali so completely different drivers are used

07:55 <krzk> and for working Mali acceleration you need both kernel drivers (open) and user-space DDK (binary only)

07:59 <zenmetsu> I have a mali T628 in my chromebook. this appears to be what's in the odroid XU3 and XU4

09:36 <krzk> zenmetsu, yes. But on chromebook you probably have ChromeOs... so they should provide you package with mali DDK

09:38 <Wizzup> It seems like he wants to use a recent kernel though - I presume the mali ddk will be usable on that as well, if the interface stays the ame

09:42 <zenmetsu> i didn't have any luck with the chromeos kernel... and all of the other kernels seem to have something wrong with them. it's almost laughable, i cannot imagine that it would be this difficult

09:42 <Wizzup> I have almost everything worked well with 4.5, except for 2d/3d accel and audio speed issues

09:43 <zenmetsu> yeah, 2d is fine, but lack of 3d accel is a dealbreaker for me

09:45 <Wizzup> I don't use a lot of 3d, and mali is 'only' opengles, so useless for most purposes.

09:46 <zenmetsu> i'm aware...

09:47 <zenmetsu> looks like i'll have to use my ancient kernel and userland binaries from the last time i did this install :/ kinda pathetic that the situation has gone from bad to worse in the past year

09:56 <amitk> zenmetsu: I have never seen a happy story with userland gpu binaries and updated kernels ever.

09:57 <amitk> I think the chromebook's upstream story is fantastic, they can't be faulted for awfully maintained mali drivers

09:57 <zenmetsu> yeah... unfortunately i had to re-visit running linux natively after chromeos axed xorg

09:59 <zenmetsu> i had been running gentoo in a chroot from chromeos and that was pretty nice, but now i can't run most graphical apps :(

10:16 <amitk> zenmetsu: just curious, what do you use the opengles acceleration with?

10:27 <zenmetsu> amitk: i do 3d modeling and have an app for my 3d printer control which is opengles capable

10:35 <amitk> zenmetsu: aah, so custom app. I haven't found too many uses for opengles in the generic desktop stack other than playing specially created graphics demos :)

11:12 <Wizzup> amitk: well, I think that maybe GLAMOR can use opengles

11:13 <Wizzup> and some window managers have support for it

11:13 <Wizzup> and maybe with the opengles->opengl emu-layer it may be somewhat useful

11:39 <sjoerd`> amitk: runing gnomne-shell on arm is a good usage of GL ES ;)

11:39 <sjoerd`> (or weston tbh)

11:45 <amitk> sjoerd`: didn't know gnome-sheel spoke opengles

11:46 <sjoerd`> it does

11:46 <sjoerd`> cogl can do both big GL and GL ES

11:46 <sjoerd`> gnome-shell is usuable in both ways otherwise you don't ~ever use it in arm :)

16:47 <zenmetsu> sjoerd', i'm still using a 3.17 kernel from one of your repos... only one i've managed to get acceleration to work with on my chromebook

16:48 <zenmetsu> only problem with that kernel is the builtin wifi driver is absent, but that's what they make usb dongles for :)

18:50 <steev> since when sjoerd` ?

18:50 <steev> gnome-shell has a full opengl check that fails horribly on arm, unless they've *finally* fixed that, and i highly doubt they did

19:43 <sjoerd`> steev: easy to disable; I've had customer projects using gnome-hsell on arm for quite a while and we've got another one using mutter as the bases of the composotir on ARM

19:45 <steev> odd, i haven't had gnome-shell work since ~3.4

19:45 <steev> i used to use the hack of symlinking bin/true to the gnome-accelerated-check-helper or whatever

19:46 <Wizzup> Ha

19:46 <steev> Wizzup: srs

19:47 <steev> https://www.youtube.com/watch?v=mETMtzMK_c8

19:47 <steev> oh 3.10

22:49 <LiquidAcid> Wizzup, hi, any luck with the g2d yet?
