1GB pages disabled and Failed to apply MSR mod on Ubuntu 23.10 about xmrig HOT 14 OPEN

There's no reason to. The kernel handles everything it needs to in that case. Your issue is because of the way the OEM of your motherboard implemented secure boot, not because Linux is missing functionality.

A quick google search indicates that turning OFF virtualization settings in the BIOS may help resolve your problem. Have you done this?

Thank you for your reply. But it does work in Windows with virtualization enabled.
Nevertheless, I'll give it a try

@geekwilliams I've tried it, but I'm still getting the same output

Updated original post with randomx bosst script output

are you running as sudo(root)?

So did you actually try to disable secure boot? #2534
As for 1GB pages, you don't need them for GhostRider.

This seems to have worked, thank you.
However, I would really like to know whether this is really the only available solution? Isn't it possible to sign the wrmsr in the same way NVIDIA or AMD sign their drivers? And import the key into Secure Boot MOK in the same way?
I would prefer to keep the Secure Boot on due to security concerns (obviously)

On the other hand, 1GB pages are still disabled. Am I correct to assume that they are enabled only for RandomX?

I don't have the answer you're looking for, but I'm curious if you installed Ubuntu with secure boot enabled? Are you dual booting this machine or did you use an install disk to boot and test?

I've installed Ubuntu on a machine with existing Windows installation, but on a separate physical disk, with a Secure Boot on.
So, from the beginning, I've had Secure Boot on and that's how I was able to correctly install the drivers.
I also have a Dual Boot, obviously, as I have an existing Windows installation, where it does work with Secure Boot on.

Weird fact is that it works in Windows, but not in Ubuntu, both with virtualization and secure boot enabled

Got it. The Ubuntu release 23.10 is a short term one, but seems to have all the same stuff as a regular LTS in terms of signing. To answer your previous question, and according to issue #1891, some system/os combos just require secure boot to be off to do CPU tweaks.

There's no way around it in your case. Windows uses the signed WinRing driver, but Linux uses built-kernel functionality to directly write to cpu registers. This is a lower level issue than xmrig, and to get any resolution you'd need to talk to your equipment manufacturer.

Okay, thanks for the reply. That's quite interesting.
So, I imagine, there is no possibility to introduce something similar to WinRing driver to Linux systems?
