environment ? ubuntu
<
si1v3r_>
did you use chrubuntu?
<
gallit>
nop. I only tried builds from linaro.
<
si1v3r_>
No idea then. Some other folks will be around later that might know more though.
<
si1v3r_>
Oooh fancy.... cardreader works in my 3.16rc7 compile.
<
Wizzup>
gallit: um, enable kernel side, get userland side, should work?
<
Wizzup>
I'm not sure about exact versions. WarheadsSE ?

gallit: are you looking for 2d acceleration?
<
Wizzup>
(mali is 3d)
<
gallit>
i'm looking for any accel...
<
gallit>
mali drivers from arm are for t608. don't know if it will work for t628
<
Wizzup>
mali is 3d, g2d and neon is 2d
<
gallit>
i have ubuntu trusty installed on sdcard. release 14.06 from linaro.
<
Wizzup>
what device?
<
gallit>
arndale-octa board (5420 exynos)
<
WarheadsSE>
I have access to t628 compatible binaries, but I can't distribute them.
<
gallit>
can you explain why ?
<
WarheadsSE>
Suffice it to say, NDA
<
WarheadsSE>
However, I think the r4pX binaries should work
<
WarheadsSE>
AFAIK, the t6xx series are all compatible
<
mdrjr>
WarheadsSE: nope
<
gallit>
do i have to build the kernel space one ?
<
sjoerd>
WarheadsSE: those won't work on a chromebook 2
<
sjoerd>
as they're build for a T604 not for a T628
<
WarheadsSE>
Would be nice if they bothered with actually making t6xx make sense.

i'd like to try the drivers. can someone explain how to build the kernel space drivers ?
<
sjoerd>
WarheadsSE: yeah
<
sjoerd>
tbh the best bet is to grab the ones from chromeos
<
Wizzup>
gallit: those are part of the kernel? so compile the kernel source
<
Wizzup>
doesn't linaro usually ship the drivers though
<
gallit>
nop. and they dropped samsung devices support at least for that month release (14.07)

gallit: iirc i got gles working on it
<
ukki>
it wasn't very fast though
<
Wizzup>
was it sw renderer?
<
ukki>
but i've given up hope on the whole board
<
ukki>
if i remember correctly
<
ukki>
i also think there are instructions at insignal forum
<
ukki>
no thanks to insignal though
<
Wizzup>
Why did you give up?
<
gallit>
didn't understand what you did...
<
ukki>
whole soc seems abandoned
<
ukki>
no gts, usb3, hw accelerated video/display etc
<
Wizzup>
that seems usual.
<
Wizzup>
a lot of that is slowly starting to work now
<
ukki>
will there ever be working big.little? or proper display driver?
<
Wizzup>
big.little already mostly works on mainline
<
Wizzup>
and fbturbo works mostly for me
<
Wizzup>
armsoc only in emergencies
<
ukki>
does fbturbo have xv support?
<
Wizzup>
what would accelerate it?
<
Wizzup>
That is done on the ddx typically
<
Wizzup>
Maybr eith g2d it does, idk.
<
Wizzup>
But you can also scale video with gles, if you have that working.
<
Wizzup>
I need to go for a bit.
<
ukki>
thanks for the info
<
ukki>
gallit: still there?
