I have written some wiki docs for vaapi codecs/hw acceleration stuff and other cool things. @tomsom Please take a look here.

This sounds great but what are the commands for arch I cannot run grubby unless I install some of the fedora grub packages.

tomsom commented 1 year ago

Very cool, just added your articles :) Thank you very much

I'll leave this issue open, try to find a way to get the same result, I will immediately insert your findings into the wiki

Never used grubby, but wouldn't it just modify GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub?

Yes it should work that way, dunno what are the differences, I just found the solution online and inserted it in the wiki

Also, it should be rerun after kernel update

stuarthayhurst commented 1 year ago

On my laptop, I just made a file /etc/modules-load.f/amd_pstate.conf, containing amd_pstate. No changes with grubby, no changes to /etc/default/grub. For me, this has worked on every boot without fail. I'm running kernel 6.1-rc5 though as I'd have to recompile again with the patch for my Samsung SSD. Somewhere later in the 6.1 cycle, I think amd-pstate=passive is required as a boot parameter, but I can't test this until I'm on a newer kernel.

What ssd patch? I could really need it. Please conitnue that research on Pstate and let us know if something interesting happens, if it functions reliably, this method should be put into the wiki asap

stuarthayhurst commented 1 year ago

The SSD patch is from this thread, but I've attached it as a file for you: nvme.patch.txt

If you're comfortable compiling your own kernel, include that patch if you're having issues with a Samsung SSD. I'd send you a copy of my patched kernel, but I built it for Debian, and I'm fairly sure you're running Fedora from what you've said?

Anyway, I'm pretty swamped at the moment, but if I get some time, I'll play around with the current linux 6.2 release candidates and see what's required to get it running reliably. There's some upstream work around the EPP part of the pstate driver, so that might take a bit more effort until it's merged, but I'll see what's required to get that running.

I can't figure out how to patch the kernel in fedora, i got kernel-devel and patch, but dunno what command i should run

Edit: maybe I found what to do, I'm waiting build finish to confirm

Edit 2: Managed to build the kernel, no luck on enabling the patch tho...

stuarthayhurst commented 1 year ago

As in you couldn't patch it, the build failed with the patch, or the patch didn't work? This is probably better on the issue for the Samsung SSD patch anyway

It seems the pstate driver will be the default and in active mode soon, so the wiki will probably need updating

Also, I noticed the links are all like https://github.com/tomsom/yoga-linux/wiki/wiki/Installation, instead of https://github.com/tomsom/yoga-linux/wiki/Installation. Having 2 /wiki/s takes you to the edit page, so normal users get redirected and given a banner saying insufficient permissions.

Nice news about pstate, for the wiki, i guess @tomsom should fix that as there are no direct ways to PR and merge edits for wikis

tomsom commented 1 year ago

Just to check that i get it right: this basically means the grubby configuration is obsolete for kernel 6.3+?

And thanks for letting me know about the wrong links, i just updated them so they should be working now :)

stuarthayhurst commented 1 year ago

The changed default won't land until kernel 6.5 at the earliest AFAIK, so the change to the GRUB config is still required for 6.3 / 6.4.

I can also confirm the links seem to be working now, thanks
