AMD Ryzen 7 PRO 3700U w/ Radeon Vega Mobile Gfx @ 2.30GHz
Linux 4.12.14-lp151.28.16-default #1 SMP Wed Sep 18 05:32:19 UTC 2019 (3e458e0) x86_64 x86_64 x86_64 GNU/Linux
The system is a Lenovo T495. I have 24Gbytes of RAM.

The test suite runs the “Heaven” benchmark. I have run it at 1920x1080. No specific benchmark data for my notebook is available, but here is some data on desktop PCs.

I am getting 1 to 2 FPS, and it doesn’t even look that fast. I am using the opensource graphic drivers and do have mesa-3d installed. Before I attempt to install the proprietary drivers, any suggestions?

Too new processor and graphics for a Linux 4.12.
Install new kernel from the Stable repo.

I think you are using graphics that bult in Ryzen 7 PRO 3700U, and not using Radeon Vega Mobile Gfx at all.
Ordinary methods - Bumblebee - works with Intel + Nvidia chips.
You have AMD + AMD.
Consult with Lenovo about Linux support.

Hi
AMD+AMD (amdgpu) works out of the box, add switcheroo control to use application for dGPU and/or use DRI_PRIME=1 from the command line.

@OP, no need to install a newer kernel (yet), add the boot kernel option amdgpu.ngg=1 via YaST -. Bootloader and see how that goes first. There are other module options to add to see if it helps.

Also can you post output from;


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
#4

Supposedly OP will need to update Mesa with X11-XOrg repository.
You will need Full repository Vendor change with this repo for a right working update.

#5

Hi
And that will help the distribution how? What we need are bug reports if it doesn’t work, else it won’t work with Leap 15.2, 15.3 or 15.4…

#6

Done. Good idea. I know about the full vendor change.

The switch didn’t help though, but might be useful when something else is fixed.

#7

To my surprise, switcheroo is actually a program. I ran it. I doesn’t ask for input. Is that where dGPU and or DRI_PRIME=1 is used?


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
07:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Device [1002:15d8] (rev d1)
        Subsystem: Lenovo Device [17aa:5125]
07:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Device [1002:15de]
        Subsystem: Lenovo Device [17aa:5125]

I added the line to the bootloader kernel options. I am not sure if that was done correctly:


resume=/dev/disk/by-uuid/611b9e33-764b-4935-b0d6-1e2da8df74eb quiet amdgpu.ngg=1

In summary, I need guidance on dGPU or that DRI_PRIME.

#8

Hi
In your case you just have the one GPU, so no need for the other stuff. So you need to raise a bug report since the 1002:15d8 is not supported in the kernel (since you have no driver present), see if they will backport (which they should do) for your new device;

openSUSE:Submitting bug reports - openSUSE

Or as indicated run the later stable kernel… which may require the later mesa etc…

Or switch to Tubleweed?

#9

Just to be clear here, was it the switcheroo I don’t need or the additional text on the bootloader?

I am going to try the kernel upgrade.

#10

Before I report a bug, I think I am onto something here. Using Yast, kernel-firmware-amd is not installed. When you try to install it, it requires dracut to upgrade to rev 49. I managed to do that with a RPM. Then trying to install kernel-firmware-amd generated the following:


cat conflicts.txt
#### YaST2 conflicts list - generated 2019-10-01 01:51:41 ####

     ] do not install kernel-firmware-amdgpu-20190909-281.1.noarch

     ] Following actions will be done:

deinstallation of broadcom-wl-6.30.223.271-lp151.11.41.x86_64

I didn’t make the changes. Since Leap 15.1 will hold multiple kernels, I assume the old 4.12 will be there in the boot menu. I altered the config to hold latest-2 and oldest.

#11

I cloned the hard drive just to be safe then did the kernel upgrade. The frames per second is now 15 rather than one.


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"

        Kernel modules: amdgpu
#12

Hi
Progress :slight_smile: So now with the later kernel if you run the command;


systool -vm amdgpu

Is the ngg parameter 1 or 0? if 0 try the boot option amdgpu.ngg=1 and see if it helps.

#13

Output with this command can be helpful:


inxi -Gxxx
#14

It was already a 1. I already had that parameter on the boot loader. Is it worth trying a 0? (I am always paranoid about not being able to boot.)

#15

#16

Hi
If it was, no need to change. I would suggest booting from a Tumbleweed Live USB and see if FPS improves (you can install on the live USB anything you need) as it will have the latest Mesa etc.

#17

Run


inxi

and look at inxi’s version.
Looks like you need to update inxi to a version 3.0+.
You can install it with a https://software.opensuse.org/package/inxi?search_term=inxi .


drivers: ati,amdgpu

IMO - you need only amdgpu, blacklist ati.


OpenGL: renderer: AMD RAVEN

Supposedly you are using GPU built in processor.
So it is worth trying a 0.

#18

Hi
There is only one GPU present in the system, it needs to be 1 for the card since it’s next generation, which it’s automatically detecting.

#19

I could boot Tumbleweed live and I guess I would download the benchmark. I will put it on the list.

BTW I only have two kernels saved even after doing the mods to the conf to save more. And both kernels are rev 5. Go figure. I have to see if that is a bug or pilot error.

#20

I’m going to put in a small SSD I have that came with the notebook and do a full installation of Tumbleweed rather than use the live version. Check back in a week.
