Correct kernel parameters pcie_ports=native or compat #59

Closed Rom888 closed 3 months ago

Rom888 commented 8 months ago

I made fresh install of ubuntu-23.04-6.4.8-t2-lunar and then upgraded to the latest v6.5.9-1 kernel.

After the upgrade suspend doesn't work (macOs: Ventura 13.2) and Google Chrome sometimes freezes the entire system.

I also noticed that there is no pcie_ports=compat in the kernel parameters. Could this be the cause of the problems?

$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.5.9-t2-lunar root=UUID=028e67b3-4f7b-4783-8315-a3fb634622ba ro pcie_ports=native intel_iommu=on iommu=pt quiet splash vt.handoff=7

You need to share journalctl -k. You can a post it to pastebin.

journalctl.txt

AdityaGarg8 commented 8 months ago

Can you try turning off hybrid graphics?

Rom888 commented 8 months ago

How can I do it? I use iGPU only now.

AdityaGarg8 commented 8 months ago

Remove apple-os-set

AdityaGarg8 commented 8 months ago

It should be sudo cp /boot/efi/efi/boot/bootx64_original.efi /boot/efi/efi/boot/bootx64.efi

AdityaGarg8 commented 8 months ago

And then restart

Rom888 commented 8 months ago

Ok, should I keep it: /etc/modprobe.d/apple-gmux.conf with: options apple-gmux force_igd=y ?

AdityaGarg8 commented 8 months ago

You can remove that, although it shouldn't interfere much when apple-set-os is removed

journalctl-amd.txt

AdityaGarg8 commented 8 months ago

What I meant was that if you are not using hybrid graphics, are you facing the issue you are facing rn?

Rom888 commented 8 months ago

With AMD graphics even shutdown doesn't work.

AdityaGarg8 commented 8 months ago

Are you using an external monitor/thunderbolt device?

Rom888 commented 8 months ago

Not now, but I am going to use it.

AdityaGarg8 commented 8 months ago

I'll see to this issue later.

Rom888 commented 8 months ago

I think I found the reason why Chrome freezes the system. Ubuntu uses iGPU:

$ glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Mesa Intel(R) UHD Graphics 630 (CFL GT2)

But in the 'chrome://gpu' there is the following: GL_RENDERER : ANGLE (AMD, Vulkan 1.3.238 (AMD Radeon Graphics (RADV NAVI14) (0x00007340)), radv-23.0.4)

It looks like Chrome uses amdGPU. I haven't found how to switch Chrome to iGPU. ?

But after switching AMD GPU DPM from auto to low Chrome stopped to freeze the system.

Anyway, resuming after suspend still doesn't work correctly.

AdityaGarg8 commented 8 months ago

If you right click on chrome and choose use discrete graphics card, does it use intel?

Rom888 commented 8 months ago

I don't understand how can I 'click on chrome'?

AdityaGarg8 commented 8 months ago

I said 'right click' on the chrome icon

Rom888 commented 8 months ago

Oh, yes, sorry. But there is no graphics card selection option on the Chrome icon.

There have some significant changes to igpu. Can you test using the latest kernel and follow the new igpu guide @Rom888 ? You need to remove the apple-os-set bootloader

Rom888 commented 6 months ago

Aditya, I read this new igpu guide. Could you please give an example how can I "Add apple_set_os as a kernel parameter". Now I have: cat /proc/cmdline

BOOT_IMAGE=/boot/vmlinuz-6.5.9-t2-lunar root=UUID=028e67b3-4f7b-4783-8315-a3fb634622ba ro pcie_ports=native intel_iommu=on iommu=pt quiet splash vt.handoff=7

Should it be? :

... iommu=pt quiet splash vt.handoff=7 apple_set_os

Yes. Follow the Permanently Add a Kernel Boot Parameter section of this guide https://wiki.ubuntu.com/Kernel/KernelBootParameters

Rom888 commented 6 months ago

Should I install apple_set_os as described here?: https://github.com/aa15032261/apple_set_os-loader#usage

I didn't find it in the latest igpu manual.

AdityaGarg8 commented 6 months ago

No it's no longer needed

AdityaGarg8 commented 6 months ago

Make sure you have the latest kernel (6.6.9) installed

Rom888 commented 6 months ago

I have installed ubuntu lunar, is it okay? I don't see this version of ubuntu here: https://github.com/t2linux/T2-Ubuntu/releases

AdityaGarg8 commented 6 months ago

The kernels are still maintained till Jan 25

AdityaGarg8 commented 6 months ago

You need to run update_t2_kernel

AdityaGarg8 commented 3 months ago

Issue shall be closed due to lack of activity after 24hrs. If you wanna keep it open, reply within 24hrs.

Rom888 commented 3 months ago

Aditya, thanks for support! My plan was to upgrade my current system to Ubuntu 23.10 and test it there. I am going to do it and let you know the results.

Rom888 commented 3 months ago

I finally did a fresh install of T2-Ubuntu 23.10

'apple_set_os' works fine as a kernel parameter.

Ubuntu uses iGPU.

chrome://gpu shows that it uses iGPU too: GL_RENDERER : ANGLE (Intel, Mesa ...)

I think we can close this issue, thank you!
