Mali-450 support by lima

Banana Pi Router design
205

Could you test 5.9-hdmi if lima works with tuxracer or glxgears? If yes i can post patch to mainline (if it is ok for you)

206

Glxgears Works!

extreme tux racer - works!

supertuxkart - works!

openarena - out of memory

Iā€™m totally fine :slight_smile: , maybe we shoul check regulators name, but i think itā€™s fine :slight_smile:

UPD. I fonund some instability on DE resolution change - on both 5.4 and 5.9

it makes a lot of output on 5.4 - so iā€™ve rebooted it. and 5.9 shows:

[  770.437126] lima 13040000.gpu: mmu command 3 timeout
[  770.949376] [drm:lima_sched_timedout_job [lima]] *ERROR* lima job timeout
[  770.956335] lima 13040000.gpu: fail to save task state from Xorg pid 2345: error task list is full
[  770.965373] lima 13040000.gpu: gp task error int_state=0 status=a
[  790.923764] broken atomic modeset userspace detected, disabling atomic

on 5.9

Likely gp task error is a DRM/mesa issue both of which are already in mainline. So it should be ok to send patch to mainline (i donā€™t have any other mali-powered board to check itā€™s behavior )

With lima unloaded ewerything is ok.

P.S. only for DE - fullscreen games seems fine.

Thanks for testing. I guess oom is not a lima/drm issue. I got oom_reapers also while using git (bare repo in lxc) at the moments git wants to repack. I solved it with a 4g swap-file on ssdā€¦maybe it helps you here too

swapfile=/var/swap.img
if [[ ! -e $swapfile ]];then
  dd if=/dev/zero of=$swapfile bs=1M count=4096
fi
chmod 0600 $swapfile
mkswap $swapfile
swapon $swapfile
208

No ssd on test board (yet, awaiting for a case) :wink: But iā€™ve created a swap partition on SD, just need to activate it.

arena with swap:

started - there are some atrifacts

testing:

ā€¦

andā€¦

:slight_smile:

OOM killer with swap, anyway - not a lima problem :wink:

renamed the regulator to look more than the others and moved mali-node to have alphabetical order:

https://patchwork.kernel.org/patch/11746419/

btw. how big is your swap (partition)?

211

:+1:

4Gb, but it seems not to be used at all :slight_smile:

212

Have you mounted it as swap (maybe swapon is also needed)? You can also try my file approach

213

Sure :slight_smile: it shows 4GB of available swap

No difference.

Anyway itā€™s out fo topic :slight_smile:

P.S. You can also test it apt-get insall openarena :wink:

Dts is now also merged including lima regulator

https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/log/?h=v5.9-next/dts32

Only the tdms-patch is now open (ck asked someone from mtk about it).

@dwmw2 for your Patch (i owned because i moved many additional nodes) i got message from Steven Rottwell:

Fixes tag

Fixes: 1f6ed224594 (ā€œarm: dts: mt7623: add Mali-450 device nodeā€)

has these problem(s):

  • SHA1 should be at least 12 digits long Can be fixed by setting core.abbrev to 12 (or more) or (for git v2.11 or later) just making sure it is not set (or set to ā€œautoā€).

It was only 11 chars but fixed by matthias to 1f6ed2245946 just as note for further Patches :slight_smile:
