Sometimes uninstalling FAH, and do
might do the trick.
FAH best configures itself if everything is working the way it should (OpenCL, GPU drivers), before installing FAH.
If your OS can't handle the wildcard, you'll have to do purge on all of them:
Code: Select all
sudo apt purge fahclient
sudo apt purge fahcontrol
sudo apt purge fahviewer
Or do:
and same for viewer, and control.
Then for safety, you can also try one (or all) of the following commands:
Code: Select all
sudo apt-get update –-fix-missing
sudo dpkg --configure -a
Try if your GPUs work the way they should (if Furmark makes sense, instead of slideshows) and if games look like they get the framerates you'd expect them to have on that type of GPU; then try reinstalling fahcontrol and fahclient, and re-set up everything in FAH.
Remember to enable GPUs in advanced settings: "GPU = true"
Restart the client, by typing
if this doesn't work, use systemd:
Code: Select all
sudo systemctl start fahclient.service

That tutorial is written for Arch based distros, your Ubuntu distro is a Debian base.
If you want to move over to Arch/Manjaro, by all means use that guide. But from looking at your log/experience so far I think you're having the exact same permission issue I was having with my RX 480 in Ubuntu.
So stop the service:
Code: Select all
$ sudo systemctl stop FAHClient.service
Modify the service to change the user back to fahclient:
/etc/systemd/system/FAHClient.service
Then add the `fahclient` to the video users group:
Code: Select all
$ sudo usermod -a -G video fahclient
$ sudo usermod -g video fahclient
Reload the systemd daemon, then restart the FAHClient.service:
Code: Select all
$ sudo systemctl daemon-reload
$ sudo systemctl start FAHClient.service
That fixed it for me, and I was in the exact same position as you with the exact same error messages in the log. Oh and I set opencl-index manually to 0 in the F@H config.

Got my rx 5700 working and it was a pain. The three key elements for me:
1. Install the OpenCL driver from the amdgpu-pro package on AMDs website. I needed to hack os-release file to make it look like ubuntu.
2. Manually edit the service to run as "root" not fahclient. In my case it was not in systemd but rather in /etc/init.d (KDE Neon based on ubuntu 18.04)
3. Configure the GPU slot manually, to use OpenCL ID as "0", not -1.
Now getting 900k PPD. This thing is beast compared to my previous 1070

The RX5700 should be faster than an RTX 2060.
The 2060 gets 1.04M PPD. The RX 5700 should get about the same, ~1.05M PPD.
I'm thinking you're running via emulation or virtualization?
Or perhaps it's CPU, or PCIE limited?
Also, did you optimize all virtualization options in bios?

No it's a native Linux install. No VM. Some units do get 1 million. CPU is a Ryzen 2700x. I can always try to turn off the CPU clients and see if I get more.
I usually run the CPU client 24/7. I run the GPu client at night when the temp drops below 20C.

I would certainly try to at least have 1 core available per 1 or 2 GPUs.
Otherwise, the GPU will need to share bandwidth with a CPU WU on a thread. This is not recommended.

I've set it to medium, which only uses 14 threads (out of 16) for the CPU clients. That's on physical core for GPU.
I also have the option of using two Open CL implementations:
Code: Select all
r_raider@HK-47:~$ clinfo

Platform Vendor Mesa
Platform Version OpenCL 1.1 Mesa 20.1.0 - kisak-mesa PPA

Right now my OpenCL index is set to 0. Maybe the other opencl library is faster?

Kernel 5.7 installed and now get 1.2m PPD on some projects. Not bad

I can report that a Radeon HD 7700 series (VERDE) card won't work on Ubuntu. Even when the permissions issue is taken care of, so FAHClient finds the card as a unit in OpenCL, all work units fail. This is with both the prorietary AMD driver (20.20-1098277, 19.20-812932), and the open ROCM and MESA versions of OpenCL. Installing packages individually and sed-patched with a new path doesn't work either - that just makes the whole FAHClient crash.

I had the same problems with getting my RX5700XT running under Ubuntu 20.04 - maybe one of the steps in the last post will help: viewtopic.php?f=108&t=35572#p337749
Good luck!

The HD 7700 series cards are based on the GCN 1st generation Verde chips. OpenCL support for those was dropped by AMD for Linux several years ago, you would have to load older versions of the drivers and may be capped at Ubuntu 16.04 or earlier. The older drivers and OpenCL support may or may not be compatible with current GPU folding cores. Their versions are somewhere prior to 18.20.
As far as I know, no one has been able to use the Mesa drivers for F@h. People would have to back port the ROCm drivers to early generation GCN chips, as I understand it AMD is not doing so.
Which version of the AMD proprietary drivers might support the 7700 series on Linux I can't say. I went down that rabbit hole looking for support for some other early gen GCN and Terascale cards and stopped looking after mention of kernel mods being needed, last version of driver with OpenCL support giving incorrect calculations and needing to go to an even older version, and so on. Basically this is one area where it probably is better to stick to Windows, AMD continued full support for these older gen cards a bit longer there. For Linux the cards are just accelerated frame buffers, not usable for GPU number crunching requiring OpenCL.
Edit: This might not apply to the HD 7790, that used a different GCN gen 2 chip. But the rest of the HD 7800 and 7900 cards were based on GCN gen 1 chips, so also are problematic on Linux for F@h.

Maybe these GPUs which don't have any working drivers should be blacklisted by the client or the server so they don't cause churning of work units. Will the client/slot eventually give up or get banned by the assignment servers when it has a 100% bad work unit rate?

Blacklisting on the client/server level would be limited because currently it is based on the GPU only, not the OS or driver. On the client level more than a set number of failures in a row on a slot should disable the slot, but that only lasts until the next restart of the client. Not foolproof, but enough to usually get the attention of the person running F@h on their system.
In the case of these HD 7700 cards, they should work on Windows but may require using a driver that provides support for OpenCL. I think in this case that might be one of the last Catalyst versions, or possibly an early Crimson driver install.

I had both a HD 7770 and an RX 580 in a Windows 10 PC, where they both were folding and producing valid results, but it seems that the 7770 was bottlenecking the RX 580; at least anecdotally the total PPD on the Windows PC seems higher without the 7770 than with it. Perhaps due to thermals, PCIe or RAM speed. The Linux box has better airflow, faster RAM and PCIe slots, so that's why I tried to run it in Linux.

Yes, I looked closer at the AMD Linux driver release notes, and although version 18.20 of the AMD Radeon pro drivers explicity supports the Radeon HD 7700 series cards,
the release notes also lists about its components: "OpenCL™1.2 (not supported for 1st generation GCN products)", as you say.
For the giggles, I installed Ubuntu 16.04 and 14.04 in a libvirt KVM and tried the last Ubuntu drivers that don't include the note about non-support for 1st gen GCN.
The good news is that on 16.04 the driver installs and PCI passthrough with IOMMU from the GPU to the virtual machine works. The bad news is that in the case of 16.04 I got the same type of error: OpenCL installs and appears to work, including clinfo, but FAH makes bad work units. And in the case of 14.04, installation failed on compiling/including the DKMS module, and no amount of kernel source packages seeemd to cure this - perhaps I just haven't tried the correct minor version of the kernel yet.
To confirm the qemu/libvirt host was set up correctly, I installed Windows 10 as a guest OS, and it appears to run the GPU fine in FAH, and it even seems to run the GPU faster than it did natively in the old Windows PC. CPU overhead is negligble in the host OS - except when Windows Update starts running.
I might test with an different version of the Linux kernel in Ubuntu and Centos in libvirt again, as the memory overhead of running a full Windows installation just to feed work to an old GPU is rather ridiculous.
