New supertuxkart on odroid xu4

[rondnelson]

I just got a new odroid xu4 yesterday, and i saw supertuxkart was released on android recently, so it now has an opengl es renderer. This brand new renderer works on Linux too if you pass a an argument (-DUSE_GLES2=1) when you use cmake to compile it. Someone already got this to work on the raspberry pi: https://www.raspberrypi.org/forums/view ... p?t=195612
I think, if it runs on the raspberry pi, the XU4 can do it a thousand times better.

So, i went to compile it.
I am using meveric's debian jessie minimal image, with MATE desktop via setup-odroid script. I downloaded the current source code, installed a bunch of dependencies, and it compiled almost perfectly, just a few unused variables and such.

When i went to run it, the program runs into an error without even going to the startup screen, this is the output:

Quite interesting project. I wanted to play STK with HD texture via OpenGL-ES 3.0 instead of GLSHIM on XU4 too.
But I have the same error message on Ubuntu.

I think it still has an issue with OpenGL-ES2.
According to the RPi log, it seems to be still using OGL instead of GLES2.
I hope meveric has time slot to check it.

[meveric]

I'll see what I can find out.
STK uses "Irrlicht" as a 3D engine.
Irrlicht has OpenGL ES backend for quite some time, I guess they finally updated their hacked Irrlicht engine to support OpenGL ES as well.
I'll try to get it to work, but no promises

[meveric]

I currently run into the same issues as @rondnelson.
Compiling is fine, but you can't start it.
This is probably taking way longer as compiling in debug mode doesn't work either.

Hi All

Chance \home\odroid\stk-code\lib\irrlicht\source\Irrlicht\CIrrDeviceLinux.cpp line number 908 from:

Code: Select all

visTempl.depth = CreationParams.WithAlphaChannel?32:24;

to

Code: Select all

visTempl.depth = 32;

then it will work

[AreaScout]

i suggest you to use 720p resolution for faster game play experience

Code: Select all

DISPLAY=:0.0 supertuxkart --screensize=1280x720 --fullscreen

RG

[meveric]

It's working now, but every now and then it crashes and also seems to have some graphical issues here and there.
Also there are a lot of options that we currently try out.
Different ODROIDs will require different settings, as the full feature only runs on OpenGL ES 3.0 but most ODROIDs only have OpenGL ES 2.0.

[rondnelson]

Thanks a bunch, areascout! Cant wait to try it out!
Its amazing how helpful and active this forum is!

[odroid]

I've just tried AreaScout patch on my Ubuntu 16.04 + Kernel 4.14.7.
It works well even on 1920x1080 resolution. But 720p is faster on a complex map.

BTW, does it use OpenGL ES 3.x properly? I didn't add "-DUSE_GLES2=1" in cmake command.

@odroid - you sure it's using GLES and not GL over glshim then?
you got this in your log:

Code: Select all

[odroid]

I didn't install glshim.
So GLES must be working. But I don't know why the warning message appears.

[AreaScout]

is it a standard image or is it in any way modified ? e.g SDL2 or so ?

@all

ok, this is how i came so far

Code: Select all

cd stk-code
wget -O supertuxkart.patch https://pastebin.com/raw/ZpB2CjZy
patch -p0 < supertuxkart.patch

this will get rid about the Graphics version warning

Code: Select all

if you look closely to that patch (https://pastebin.com/ZpB2CjZy) it does now the parsing of the renderer string right for Mali driver on ODROID's and in general, this is useful for graphical restrictions configured per driver version for different ODROID boards e.g GLES2 only boards like C2

after installing the game this can be configured in that file /usr/local/share/supertuxkart/data/graphical_restrictions.xml here is an example

Code: Select all

<card contains="Mali"             os="linux"    version="<3.1"    disable="HighDefinitionTextures"/>

i don't know all of this graphical restriction strings and what they are for, but this is something one can play around now to get the best performance out of that game

I'm using this Ubuntu image and updated kernel to 4.14.7.
https://wiki.odroid.com/odroid-xu4/os_i ... 4/20171212
It contains a slightly modified SDL2 to disable the mesa-softgl.
Anyway, I've already spent a couple of hours to play this nice game.

ok i use this 'ubuntu-16.04.3-4.14-mate-odroid-xu4-20171126.img', i will try the newer one now

The Game looks nice ! FPS is slow here and there, guess i have to test more on this

[meveric]

Seems I finally figured out the last issues and can also apply some optimization to the game which hopefully means it should run a little bit faster.
I got rid of the crashes in some of the tracks, which for example prevented the use of the Story Mode.
I already have fully working versions for the C2, but I'm now building them for armhf boards.
I've already have some packages, just need to add the new binaries then I can upload it to my repository

There were a couple issues that worked together here:
1. you need to pass the -marm parameter during compiling, or else you run into a memory issue which caused the crash we saw earlier.
2. if you pass the -marm parameter the build failed when it tried to compile ASM code for angelscript
3. reason for that is, cause you need the -mfpu=neon-vfpv4 flag, or else it uses gcc default which normally is: --with-fpu=vfpv3-d16 and for that misses some registers that are required to compile angelscript
4. the CMakeFile.txt for angelscript has an error in it, it compiles the ASM code without using any compiler flag, so you need to make sure that you pass -mfpu=neon-vfpv4 here or else the compiling will fail due to 3.

After that I had no issues with supertuxkart on ODROID XU4 anymore and no crashes.

I'm currently try to figure out if optimizing specifically for XU4 (and other boards) does give us some speed benefits, or if "general options" are good enough, so either one binary for each board series, X/X2/U2/U3, C0/C1/C1+, XU3/XU4
or one binary for all boards.

[meveric]

I've uploaded my packages to my repository viewtopic.php?p=209564#p209564 and added a new topic in the Games forum viewtopic.php?f=91&t=29366
Please note, that I only provide packages for Debian not Ubuntu.

[odroid]

Thank you for sharing the packages. This game is really nice.

[deve]

Hi,

The issue with 32bit visual should be fixed:
https://github.com/supertuxkart/stk-cod ... 13093b8fcd

And I suggest to try current git STK version, because Benau made a lot of optimizations in the graphical engine. For me some tracks are ~50% faster on android when advanced lighting is disabled. Advanced lighting should be faster too.

And btw. for raspbery pi we need texture size <= 256. It is in graphical restrictions:
<card vendor="Broadcom" os="linux" disable="HighDefinitionTextures256"/>

Do you need such restriction for odroid?

[meveric]

No we don't need these restrictions on ODROIDs.

Advanced lighting disabled is no issues on ODROIDs, we can have over 100 FPS (in 1080p) with advanced lightning disable, so speed in that case was never an issue.
Advanced lighting enabled requires OpenGL ES 3.0 or higher which is available on the ODROID XU3/XU4 so nothing the RPi can even use and this is very demanding, but the graphics are a lot better in that case.

I'll check if the current git actually has improved graphics performance but I don't think it will be much faster, and as I said, without advanced lighting performance was never an issue on a device like an ODROID.

[k06a]

3. reason for that is, cause you need the -mfpu=neon-vfpv4 flag, or else it uses gcc default which normally is: --with-fpu=vfpv3-d16 and for that misses some registers that are required to compile angelscript

Thanks for mentioning it. I have a similar problem right now, how did you solve it? https://stackoverflow.com/questions/517 ... -under-arm

[meveric]

well cortex-a15.cortex-a7 is not armv7-a but armv7ve although I doubt it makes much of a difference, in your case.
but this issue has nothing to do with what is described here. In the case above, there are arm registers for ASM that are not available with fpu=vfpv3-d16.
Your code has some completely different issue.
Still as other guys suggest it seems you're missing -mfpu=neon in order to use these functions.
Why don't you just add it to your other flags that you already added?
