<KotCzarny>
did something change in either ump or cedrus?

which kernel version?
<KotCzarny>
armbian's
<KotCzarny>
3.4.113+
<KotCzarny>
self compiled, but it looks like i have to use some special libump repo
<plaes>
ah.. no idea :(
<KotCzarny>
mosterta's or rellla's
<KotCzarny>
which is weird, because at this time checking out libump and libcedrus from 'official' repos are incompatible

MoeIcenowy: what does Xv need? shouldn't it be possible to implement it in xf86-video-modesetting?
<KotCzarny>
xv requires yup planes i think
<KotCzarny>
*yuv
<wens>
well, you should be able to ask drm/kms if it has any yuv planes
<wens>
if yes, then you could declare support for Xv, no?
<rellla>
KotCzarny: you have to explicitely compile libcedrus with USE_UMP to get ump support, so in case you compile it without, it should be compatible to standard ump. otherwise you can use mine.
<rellla>
you only need it, if you want to use to same memory with all three. ve, mali, disp btw
<KotCzarny>
rellla, i did, and it found other symbols, but this one it was missing
<KotCzarny>
i've checked now both libump and libcedrus from your repo and it compiled/ran ok
<KotCzarny>
you might want to update links on your talk page
<rellla>
so what is the issue with the original ones? they should work, too?!
<KotCzarny>
as i get access denied when using cmdlines you have there
<KotCzarny>
rellla, nope, if you check 'official' libump its missing that symbol
<rellla>
yeah. need to use the https links instead
<KotCzarny>
now this is new. hung at <6>Waiting for root device /dev/mmcblk0p2...
<KotCzarny>
and cma failed to reserve 300M
<KotCzarny>
hum
<rellla>
take 128
<KotCzarny>
is there kernel cmdline param for cma?
<rellla>
afaik no
<KotCzarny>
drat.
<KotCzarny>
i forgot to make a backup of the kernel
<rellla>
how do you build your kernel?
<KotCzarny>
on the device
<KotCzarny>
at least i have mainline one available, so i can boot and recompile
<rellla>
and base distro is armbian?
<KotCzarny>
yes
IgorPec has quit [Ping timeout: 246 seconds]
<rellla>
i remember i had issues with a kernel from scratch on armbia dist
<rellla>
initrd and such things...
<KotCzarny>
nah, i dont use initrd
<KotCzarny>
since it's a tailored kernel (and not the distro's one) i dont need such thing
<rellla>
so i now use armbian build tools on another machine and use the debs.
<KotCzarny>
hard to install debs in case something goes wrong ;)
<KotCzarny>
There is also a cma= kernel command line option. It lets one specify the size of the area at boot time without the need to recompile the kernel. This option specifies the size in bytes and accepts the usual suffixes.
<KotCzarny>
oh
<KotCzarny>
i find it beautiful that allwinner got unbrickableness right
<Char0n>
at least one thing
<KotCzarny>
but essential one
<Char0n>
true. FEL is awesome.
<KotCzarny>
char0n: and using sdcard as highest priority
<KotCzarny>
ok, 128M got reserved
<Char0n>
it do? good to know
<KotCzarny>
vendors can probably reconfigure it, but so far i havent' heard of the exception
<KotCzarny>
umkay, /dev/cedar_dev is there, yay
<KotCzarny>
aaaand takeoff, we have visual!
<KotCzarny>
even osd works
<Char0n>
gratz
<KotCzarny>
thank you sunxi devs!

is cedar configurable in any way ? some smoothing or postprocessing?
<KotCzarny>
and the best part? decoding video with only 15% cpu usage at 528mhz
<Char0n>
On which device / chipset?
<KotCzarny>
a20 (bpi m1)
<Char0n>
mh, have A23 here. the 'little brother' of A20. but got it never to work with linux.
<Char0n>
maybe i should try again
<KotCzarny>
legacy kernel required unfortunatelly, but at least cedrus is working nicely
<KotCzarny>
and a20 has a big bonus of G2D acceleration
<KotCzarny>
some videos crash in audio decoder, hrm
<KotCzarny>
but even software decoding videos (but using xv/g2d accel) works perfectly
<KotCzarny>
and a23 wiki page could use some updates: u-boot-sunxi has basic support for A23, which includes UART console (including R_UART) and MMC. Disclaimer: no one has actually booted a kernel with this yet.
<KotCzarny>
;)
<KotCzarny>
g2d is part of which block? or something independent? because it's a big win to make decend desktop experience possible
<rellla>
yes. independent.
<rellla>
newer socs use pixman in libvdpau-sunxi to blit the rgba osd.
<rellla>
cpu based, but works well, too.
<KotCzarny>
its not only osd, fbturbo gets big boost thanks to it
<KotCzarny>
i might say a20 is the best soc to use as an allwinner's desktop core
<KotCzarny>
it's a night and day difference, firefox is actually usable now (even with compilation running in bg)
<KotCzarny>
i wonder if fbturbo could use cedrus accel functions on h3+
chomwitt has joined #linux-sunxi
<jernej>
rellla: libvdpau-sunxi could use overlay planes for OSD on H3, right?
<rellla>
yes.

hrm, picture is much more darker with cedrus than with sw decode on mplayer
<dgp>
Disabling a core should reduce power consumption right? I thought that was what the BSP kernel does to reduce heat but I don't see any different in current on mainline.
<KotCzarny>
reducing voltage (and max cpu freq possible) reduces heat
<dgp>
Every time I see a comment from tkaiser about the BSP kernel he says it "kills cores" so I thought that was it turning them off
<KotCzarny>
sure
Ntemis has quit [Read error: Connection reset by peer]
<KotCzarny>
killing core MIGHT help, by reducing available cpu power
<KotCzarny>
but if your load on one core (with three available) is enough to overheat..
<KotCzarny>
then killing idle core wouldnt show you much of a difference
<dgp>
not so worried about heat. Wondering why it consumes 1w when idle with all the cores enabled and exactly 1w when idle with all but one core disabled
<KotCzarny>
measure again under load
<dgp>
maybe I don't have the resolution to measure the tiny difference :/
<KotCzarny>
yeah

is it ok to leave a battery charging with axp223 on mainline, or is that... "not recommended", especially given that my battery does not have a thermistor
