hi all, I want to enable the mali gpu on the a13 with the mainline kernel for X11 and generally for 3d rendering
<marble_visions>
from what I understand i need the mali driver, and the ump userspace library
<marble_visions>
everyone talks about libump being closed source => the mali driver is not accepted in mainline
<marble_visions>
but I'm seeing the ump sourcecode on arm's site -- why's that?

and it's not even remotely as friendly as other gpu blobs
victhor has joined #linux-sunxi
<marble_visions>
i'll make it bark and sit.. somehow. i just need to get the bigger picture of the gpu stack and how it integrates with the rest of the system
<marble_visions>
great, ump userspace sources download from arm is broken
<Ke>
I think you'll need libmali, ump or dma-buf and mali-drm
<Ke>
dma-buf is afaik preferred solution for newer kernels
afaerber has joined #linux-sunxi
<marble_visions>
MoeIcenowy: Ke: thanks for info!
<marble_visions>
alright, i'll see what i can come up with
<MoeIcenowy>
marble_visions: you can refer to the kernel source code of C.H.I.P for more info.
<MoeIcenowy>
C.H.I.P. also released a r6p0 dma-buf libMali blob suitable to be used with sun4i-drm driver in mainline.
<marble_visions>

ssvb, about cma working ok even with ramdisk?
<KotCzarny>
yeah
<ssvb>
it can't be working ok with 300MB CMA at 0x4d400000
<KotCzarny>
ssvb, shouldnt it fail then?
<ssvb>
have you tested hardware accelerated video decoding via libvdpau-sunxi?
<KotCzarny>
i will check with the droid in the evening, because i have only basic rescue linux atm
<KotCzarny>
it was opipc if it makes any difference
<ssvb>
any memory buffers for the VE have to be allocated in the first 256 MiB of DRAM
<ssvb>
at least on A10/A13/A20
<KotCzarny>
but i think i had ramdisk loading at 47800000 with the droid and video decoding worked ok there
<ssvb>
jemk: what is the current status of the 256 MiB limit? I see that https://linux-sunxi.org/VE_Register_guide mentions "HI bits", has this problem been resolved now?
<ssvb>
KotCzarny: it would be great if we can double check and confirm it
<xal1us>
finally back from FOSDEM... does anyone know who got the new version of the 14" Pinebook from Tl?
<KotCzarny>
for sure i'm using droid in such config, but it's legacy kernel and android
<KotCzarny>
i can boot and check how cma is reserved though
<ssvb>
KotCzarny: it's also interesting how the VE buffers are allocated there, are they really coming from CMA?
<KotCzarny>
ssvb, want my droid installer? only 160megs
<KotCzarny>
it's also mainline uboot based, so can happily coexist with another os
<ssvb>
if jemk has time, he can probably explain what's the current 256 MiB limit story on different Allwinner SoCs
<ssvb>
maybe H3 is not affected, or maybe it was discovered later how to fix this problem on older SoCs too, I just don't want to speculate
<KotCzarny>
ok, will dmesg suffice or want me to play some vids and copy logcat too?
<Ke>
it's really starting to look like the year of linux on ARM
<KotCzarny>
we will see how much political promises will convert into useful code
<MoeIcenowy>
let us try to persuade Allwinner that make chips more open is better ;-)
<MoeIcenowy>
KotCzarny: from my belief, 0
<KotCzarny>
;)
<MoeIcenowy>
P.S. how to submit a device with no brand name and very generic PCB ID?
<MoeIcenowy>
It's a "H8vr" device
<KotCzarny>
allwinner is going money's way still, i wonder how big % of their chip sales go into sbc
<KotCzarny>
MoeIcenowy: no markings on pcb?
<MoeIcenowy>
there is
<MoeIcenowy>
"V8C_H8_V1_1"
<MoeIcenowy>
"QL 1646"
<Ke>
well phoronix practically promised we will have open powervr drivers even
<Ke>
we will have good drivers, we will have the best drivers
<KotCzarny>
MoeIcenowy: similar page as in q8 case?
<MoeIcenowy>
call it V8C H8 v1.1 ?

Has anybody ever had issues with microSD cards specifically on H3 boards that periodically will fail writes with WP_VIOLATION status?

or maybe there should be 'unknown' brand to mark devices which require more data

<TheLinuxBug>
you need someone else to test it for you?
<fALSO>
if anyone wants to compare
<fALSO>
i also had a friend test on a ODROID
<TheLinuxBug>
if you want to give link to image ill happily load it and test it
<fALSO>
the orange cpu is faster than the ODROID
<fALSO>
but the ram in the ODOID is MUUUUUUUUCH faster
<KotCzarny>
59C is conservative, they can happily churn at 70
<fALSO>
without the cooler it got to 68
<fALSO>
with the cooler it never passes 59
<fALSO>
its a tiny cooler that i bought for a RPI, but never used it
<fALSO>
the two smaller ones didnt use
<fALSO>
the memory chips dont get very hot
<KotCzarny>
they are not intels, you can go to 70 in the table
<fALSO>
now im having a little problem in gentoo
<fALSO>
cant build binutils :-P
<fALSO>
the memory ends
<fALSO>
and gcc gets killed
<KotCzarny>
use zswap
<fALSO>
already added 1GB of swap but its not enought
<fALSO>
gotta get a 32gb card
<fALSO>
to use like 4gb or swap or something like that
<fALSO>
gotta leave, back in a few hours
<KotCzarny>
give it a 1gig and it will have insta 1gb+3gb (when using gcc)
<fALSO>
i just found how this channel, going to stick around :-D
<fALSO>
found out
<fALSO>
kotczarny, nice going to try it when i get back :-D
<KotCzarny>
opipc2 has 2gb physical ram right?
<KotCzarny>
i was able to compile android on 2.5gb machine (at peak it was going up to 6gb) and without zswap it was ~50 minutes because of swap churn, with zswap it went down to 5 minutes

KotCzarny, 1GB for PC2
<KotCzarny>
ahm, then probably 512mb for zswap could be more realistic (still, it will virtually convert into ~2gb of ram)
<xal1us>
I made a Gentoo test image for Pine64 and that works fine so far with MAKEOPTS="-j3"
