5schatten It seems you can enable GCN 1.0 and 1.1 cards support in the amdgpu driver:
AMDGPU vs. Radeon DRM Driver Performance On Linux 4.15 - Phoronix
AMDGPU+RADV Linux Gaming On GCN 1.0/1.1, 25-Way Warhammer II GPU Benchmarks - Phoronix
If it's easy to do it would be great to test that, because it means Vulkan support for these cards and maybe fixed audio issues!
Unfortunately I can't do new tests on AMD GPU hardware until Christmas.
Worth a try!
Any chance of including parsec for s905? They have a build for raspberry pi, it should work with s905, right?
Thanks for your work!
Well I've only found a binary for RPi3 so maybe this one works too on other platforms but without the source code I can't compile it for AML based systems.
Display MoreI have installed LibreELEC-S905.arm-9.0-RR-201847-b559485-Beta16.img.gz on a Samsung EVO 32GB MicroSD and running it on a Wechip V5 S905X based device.
It boots fine and kodi works fine
I have a Genuine Sony PS4 Bluetooth Controller and that is paired fine with LE. I also have a usb keyboard plugged in
When I start Emulationstation it finds the ROMS and lists the platforms correctly. I have a snes rom, a sinclair rom and a c64 rom installed for testing.
In Emulationstation both the keyboard and PS4 Controller work fine.
When I launch any of the roms it fires up retroarch and runs the rom correctly, the music/sound is working fine.
However both the usb keyboard and ps4 controller dont work inside retroarch.
Please let me know what needs to be done to get the controller+keyboard working inside retroarch
Also please let me know where should I put the ATARI5200 BIOS files. I put them in the /storage/roms/bios folder but it still says "Atari800/OS Emulation Halted"
Thanks
You have to start the atari800/5200 and set it to 5200 in it's core options. Start again & it should work.
Can you disconnect your controller and run retroarch just with the kb connected to see if it this works? From my experience not input is recognized at all if the controller cfg file is wrong mapped. Can you state your detailed model number of the controller?
Display MoreThnx for reply.
I configured sound and set it to my sound device, same problem. Its stuck in the wii (White) starting screen where it shows you the controller.

So i guess its an retroarch issue or broken config file.
again when i start dolphin manual --> /bin/dolphin.start it works (without sound)
Again Retroarch starts libretro-dolphin while Emulationstation starts Dolphin standalone.
What is the output of aplay -L upload it.
What is the content of your asound.conf
What is the content of your advanced.conf
If the you enter the correct output device the sound works for all emulators beside some edge cases like citra & nvidia cards...
First of all thank you very much for this build many emulators work out of the box wich is great. Dolphin is not starting true retroarch. But when i start dolphin manually with "/bin/dolphin.start" and i confugure sound (Audio Backend) to "No Audio Output" it start the game (also playable), but when i set it to ALSA it crashes (return to kodi home screen) or screen stays black

I did not alter asound.conf, so i guess im using the autoconfig.
any ideas on how to analyse this problem ?
set autoconfig to false in \\your-device\Configfiles\rr-config\advanced.conf then get a list of your output devices by entering aplay -L in a terminal & finally add this device to your asound.conf
Retroarch uses lr-dolphin which has nothing to do with standalone Dolphin which you start in Emulationstation. Most of the standalone emulators rely on SDL for audio output so if the ALSA backend is not configured correct they won't work.
Well as long as it runs your stuff it's fine I guess.
Nope
bapm=1 does not work
Well okay then it's probably a dead end. This bug exists for years now and you have already the latest bios so this workaround is probably the best you can do 
Yeah, I've read about the stupid msi motherboards, anyhow radeon.dpm=0 seems to work! I don't know what it does but I'm in!
Thank You for all the help!
Don't get to excited. Does radeon.bapm=1 work? Because afaik dpm=0 will disable power management for your cpu.
Display MoreOK so with AMD open-source drivers I have:
-bad HDMI audio
-no vulkan
-no kms
-a bug message with GL with Dolphin
GREAT!
I'll try the intergrated gpu of the i5 3750 the next time I have access to this PC
To be fair kms is basically working but IMHO Retroarch has a faulty implementation since in the bug report someone stated kmscube needed a patch too & since others suffer from the same Failed to create shared context for shader compiling bug with newer RX 470 cards+amdgpu driver it's not an exclusiv bug for you 
I would recommend to create a new issue here Tickets - Emulator - Dolphin Issue tracker and hopefully some of the Dolphin devs have a look at it.
Also it might be a Mesa 18.3.0 problem because someone at the arch user repo has a this problem too:
would like to return to stable mesa but am having trouble doing so.
I tried
pacman -S vulkan-radeon lib32-vulkan-radeon lib32-mesa mesa lib32-llvm-libs llvm-libs lib32-llvm llvm clangbut Steam fails to launch with "Main.cpp (332) : Assertion Failed: Fatal Error: glXChooseVisual failed" and Dolphin Emulator will tell me "Failed to create shared context for shader compiling." a couple times before it boots.
5schatten "Vulkan" worked... but only to an error message when starting dolphin "No vulkan physical devices available"
Logfile of Dolphin when it does not start in Vulkan mode?
EDIT:
Well okay I guess the cards just does not support it. https://www.reddit.com/r/linux_gaming…280x_in/dharjei
So bascially KMS is buggy because of driver and/or Retroarch quirk and Vulkan is not available for this GPUs
But hey praise AMDs open source drivers...
Without it, I'm getting a quick black screen with a bootloop, gonna try without and see if I can get another quick dmesg off
Well with this nomodeset flag it's basically useless because it "covers" the root of the problem.
EDIT: well I guess your board is somewhat doomed

5schatten I tried to change GFXBackend = VULKAN in dolphin.ini but it doesn't change anything, I'm not sure dolphin take it into account, other problem I have is the low res UI interface for dolphin so some option are hidden/out of the scrren, every tricks you told me to fix this have failed.
Try GFXBackend = Vulkan maybe it's case sensitive

Well you've manually set nomodeset? Because this disables your GPU drivers so you should not expect to get a working system

EDIT: In fact I have a terminal screen on my TV, the first line saying:
[FAILED] Failed to start Xorg Server
Well my assumption was wrong -> I thought radeon & amdgpu cover somewhat similiar GPU and amdgpu is just a newer driver but only Vulkan Islands & newer, so the r9 285, are supported by this driver. And as stated before it's most likely a bug in either Mesa or Retroarch so no chance for me to resolve this problem.
Then again try to run Dolphin with Vulkan backend because then you'll know if Vulkan works at all.
It failed > just a black screen after the libreelec boot screen.
but ssh was still working so it was easy to remove these added files.
Well I made some further research and it turn out it's probably a mesa or RA bug (Video) KMS no longer works with mesa · Issue #7119 · libretro/RetroArch · GitHub so stick to GL for now since I can't do anything about this
5schatten hmm i see the RC1 Pi build was pulled, any particular reason?
Not really but they've been testing builds and since AMD needs further polish I've removed them.
5schatten, Thank you for your response. I've forgotten to mention I am using the S905 build and do not have the option to try the Retropie instructions.
Thank you for creating the ticket. I really hope something will work out.
Well that's exactly the same... you have to connect by ssh and follow the steps I've linked. Otherwise use the LibreELEC settings menu and try to connect these controller in the bluetooth menu. These steps are independent of your platform so for generic, RPi & S905 you have to do the same.
If after following these steps you don’t get the controller to connect, or the connection is unreliable (ex. only connected once). Make sure you are using a genuing controller. The market is flooded with high quality fakes.
atm im a bit removed from a situation from accessing my only SD reader atm (which is basicly my MacMini) is there a means to do it live on the pi (albeit via PuTTY?)
I'm not sure if this would work with board utilities while the partition is mounted. But would probably work with an usb stick and something like Linux Mint which comes with GParted or something similiar
I figured it would work out of the box seeing as LibreELEC 8.9 did. After disabling autoconfig and re-editing asound.conf, retroarch games have sound (albeit very glitchy as if sample rate was wrong or something can't keep up) and kodi still has no sound.
The autoconfiguration can only work if you've set the correct output device in Kodi before. How should any programm know out of the box which output you'll use? It can gather a summary of all devices but if you use your HDMI or IEC958 or audio jack... there's a reason why you still have to set this first.
What about a way of exiting spotify?
Thank you
Seriously?
For dolphin the error message is not blocking, the game starts fine after this with opengl. But it is not very intuitive since you need to use a mouse to click 2 times on the ok button to pass the error message.
So does Dolphin run games with Vulkan backend? Have you tried difffent shader settings?
EDIT:
So maybe it's the "radeon" driver that just won't work well I've read a bit and since LE comes with both the radeon& amdgpu drivers maybe we should give the latter a try. Could you create the xorg.conf file and check if it works if you put in this? Then xorg should use the amdgpu driver which is probably more suitable for newer AMD stuff.
Also you could try this echo "blacklist radeon" > /storage/.config/modprobe.d/radeon.conf and blacklist the radeon kernel driver to force the amdgpu one.
Just make sure you have a backup in case this prevent's xorg from loading. Because you serve as a guinea pig
