New GPU: AMD M370X (Macbook Pro 15" mid-2015, running Linux)

[Carrot]

Hi

I tried searching the GPUs.txt for the GPU of my mid-2015 MBP 15" with the AMD M370X GPU, didn't find any with the full string. I found one with part of the first string, but the second isn't there at all.

GPU: AMD ATI Radeon HD 8870M / R9 M270X/M370X according to neofetch

Anyway, here's my output:

If neccessary, I'll upload a copy of my log.txt too. Afaict, there's no upload-doc feature on the board, so I'll have to put in in a pastebin or some other means.

GPU folding is not supported using the macOS, but the device ID for the GPU is listed, the first AMD item in the output:

0x1002:0x6821:1:5:[Radeon HD 8800M Series]

The description field was probably entered years ago when the first GPUs with this chip were released by AMD. For later ones AMD just used the same ID and the list was never updated. But it would not matter for the client, it uses the description only for display, and uses the ID for setting things up.

Booted up into Linux or Windows your MBP should be able to use this GPU, but a quick lookup did not show whether it supports use of Double Precision calculations.

Aha, I see

As to actually using the GPU, I'm currently running Linux on it (Kubuntu 19.10), with Kisak PPA for latest Mesa and 5.5.3 kernel, but the web interface for FAH only show it using the CPU. Is there some option/parameter that have to be set by me to enable it to run on GPU?

[Joe_H]

Under Linux you need the AMD proprietary drivers, OpenCL support from them, and possibly the OpenCL dev kit installed. 19.10 has had some other issues reported, I don't remember all of the details. But mostly connected with the client using older libraries for the code. So there might be some dependencies to take care of.

If the installer did not "see" the GPU at install time it sets an option that you will need to change. In FAHControl use Configure and click on the Expert tab. If the option gpu is there and set to false, remove it and set the option gpu and set that to true. Save the changes and restart the FAHClient process or reboot.

The next time FAHClient starts it should detect the GPU and allow adding folding slot for it.

This card does support OpenCL 1.2 and Double Precision floating point math.

Any special reason for requiring proprietary (AMDGPU-PRO) drivers on Linux? There seems at least to be some dependenciy issues with installing the FAHControl package.

I'm having issues getting FAHControl to run. It installs, in some fashion, appearing in my app menu, but "running" the entry doesn't seem to do anything.

Code: Select all

§ sudo dpkg -i --force-depends fahcontrol_7.5.1-1_all.deb

Must I manually install python-gnome2, python-dh and python-support?

Ran

Code: Select all

§ sudo dpkg -i --force-all ~/Downloads/fahcontrol_7.5.1-1_all.deb

with the same result.

[Joe_H]

I remember a post from someone where they changed a line at the beginning of FAHControl to point to python instead of python2 and that getting it to work with the current installed version. I don't recall if there were other issues connected with that, but perhaps this will give you something to look for.

As for the proprietary drivers, the experience has been that the GPU folding core has not worked with the open source drivers. I have not seen any info that situation has changed.

I was able to get my GPU working (or at least show up in F@H webview) on my mid-2015 Macbook Pro 15" doing the following:

Code: Select all

sudo nano /etc/fahclient/config.xml

Line 6: Changed from

Code: Select all

<gpu v='false'/>

to

Code: Select all

<gpu v='true'/>

Line 18: Added

<slot id='1' type='GPU'/>

Code: Select all

FAHControl can be installed with this .deb, which has stripped out the faulty dependencies.
