Lightbulb Debian 8/ Deepin 15.8 on Acer Nitro 5, (Ryzen 5 2500U and RX 560X)


I have Deepin 15.8 (based on Debian 8) chugging on my laptop, dual booted with Windows 10.
Due to the wobbly driver support from AMD, I faced some hurdles trying to get it to run. I have been able to solve some of them while others currently have no solution, and require a kernel update.
This thread is meant to serve as a quick reference to anyone using Ryzen mobile who wishes to use Linux on their system.

Solved Problems

1. CPU soft lockup
The system cannot boot, and experiences CPU soft lockups and consequently very high CPU usage.
Solution: Disable ACPI, and limit processor state.
Edit GRUB, set GRUB_CMDLINE_LINUX_DEFAULT as:
Code:
GRUB_CMDLINE_LINUX_DEFAULT = nosplash pci=noacpi rcu_nocbs = 0-7 processor max_cstate = 1
2. Touchpad not working
Solution: This is fairly straightforward. We simply add some GRUB parameters telling it to use default touchpad drivers.
Add the following to GRUB_CMDLINE_LINUX_DEFAULT:
Code:
i8042.reset i8042.nomux i8042.nopnp i8042.noloop
3. Debian repos inaccessible via apt(OS specific issue)
While Deepin 15.8 is based on Debian, apt is restricted only to Deepin’s repository. While this repo has most of the common applications, it is bereft of several other popular Debian apps.
Solution: edit sources.list (/etc/apt), comment out the Deepin repository, and add The repositories listed here, replacing “stretch” with “Jessie”

4. Time Issues with Windows (general issue)
The issue here is that Windows sets the BIOS time as the local time, while Debian sets it as UTC.
Solution: Set hardware time as local time in Linux.
NOTE: This needs to be updated whenever the System time is updated, else it doesn’t auto update the time.

Unsolved Problems

1. Battery Life
Booting itself required ACPI to be disabled. I’m not sure if this is the only reason, but I get much lower battery life on Linux compared to Windows (2hrs vs 5 hrs on average).
This can be resolved only when the CPU gets support for ACPI which is dependent on driver of AMD.

2. Switchable graphics:
Xrandr should be able to switch between the integrated and dedicated GPUs. However, because of the way drivers are packaged, only a single driver is given for the APU and GPU which I suspect results in Xrandr only detecting the integrated GPU.
Again, this ought to be fixed in a driver update for amdgpu that we’ll receive soon (hopefully).

3. Radeontop misreporting usage(?):
A consequence of the above problem, Radeontop incorrectly shows the Vega 8 to be at 100% utilization, as it is not compatible with Raven Ridge.
The RX 560X on the other hand, is shown as an “unidentified Polaris 11” card with 0% utilization. I’m not sure if this is accurate or another misrepresentation which happens to be correct.

4. Suspend/ Sleep
This too, depends on ACPI. Disabling ACPI prevents the OS from suspending and the laptop needs to be force shut down in such cases.

Unknown

1. RoCM Compatibility:
RoCM should be compatible with the Polaris 11 RX 560X present in the laptop. However, I haven't had the time to download it and test. Would appreciate if anyone helped out by trying it and testing with CUDA like codes, such as Neural Network training algos in tf-GPU for RoCM, and let me know.

Set the windows RealTimeIsUniversal instead you will never have to mess with the time again.

Awesome !
Will I have to manually change my time zone when I travel ?
Or will Windows detect my location and automatically change it ?

This isnt the best fix for this. The best fix is finding the hardware that isn't being enumerated and adding it to the grub commandline (ie, on my Inspiron 7375, I have 'amd_iommu=on ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2')

Could you please help me do this ?
How do I "debug" the bootup so I can find what's not getting enumerated ?

Let me see if I can find the article that explained exactly how to find exactly which hardware wasn't being properly passed to the kernel and causing it. I was lucky in that I found a thread that someone else did the legwork for my 7375 and posted the hardware that was missing so I didn't have to look myself, and thus far it seems the bios on my Lenovo w/ pro 2500u is passing all the hardware correctly as of the latest bios patch.

UPDATE: I replaced the Deepin installation with Manjaro 18.0.2 (Deepin) and almost all problems have been solved.

Kernel version is 4.19

Due to this rocm opencl is not working
Code:
$/opt/rocm/opencl/bin/x86_64/clinfo

Can someone help me with this?
I ve updated kernel to 4.20.11-042011-generic

I raised an issue on the RoCM github repo and was told that they are still working towards multi GPU support for the ROCK driver.

The only way around this is to disable the Vega iGPU. Unfortunately, Acer hasn't provided any such utility in the BIOS, and when I asked their support, I was told that they had no clue when it would be added.

What is the output of running clinfo directly(you may need to install clinfo first via apt):
Code:
$clinfo
Also, can you specify the output of running
Code:
$xrandr --listproviders

Thank you for your reply. Here is the output of the commands
Code:
$clinfo
ERROR: clGetPlatformIDs(-1001)

$xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x55 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:Unknown AMD Radeon GPU @ pci:0000:04:00.0
It appears to be an issue with kernel not able to initialize the GPU at boot. I have posted the dmesg report in previous reply. I have also tried installing the proprietory amdgpu drivers for RX 560 since drivers for RX 560X are not yet available. But clinfo is still the same. So is the dmesg report

Something is probably wrong with your opencl installation. I suggest installing it via
Code:
$sudo apt install clinfo
Then try to run clinfo and tell me if anything changes.

$xrandr --listproviders
Providers: number : 1 Provider 0: id: 0x55 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 2 associated providers: 0 name:Unknown AMD Radeon GPU @ pci:0000:04:00.0
It looks like only the Vega is getting recognized by Xrandr, as only PCI 4 is listed.

If you're on kernel 4.20, you ought to be seeing 2 providers being listed.

What is the output of running
Code:
$uname -r
To verify your GPUs, please install Radeontop.
Code:
$sudo apt install radeontop
Run and provide the output of:
Code:
$sudo radeontop -b 0
Code:
$sudo radeontop -b 4
Alternatively, give the output of
Code:
lspci -k

Thank you for the reply. After doing
Code:
$sudo apt install clinfo
and trying clinfo now getting
Code:
Number of platforms                               0
Code:
$uname -r

4.20.11-042011-generic
Like you said even I was expecting proper gpu support with 4.20. Maybe I ve done something wrong.

Code:
$sudo radeontop -b 0

Failed to open DRM node, no VRAM support.

If i can get opencl to work either through ROCM or amdgpu then I can install tensorflow or PlaidML and start some deep learning.

The output of lspci and Radeon indicates both the GPUs are connected properly.

Try running the below to update your drivers and check Xrandr again.
Code:
$sudo apt install amdgpu
