From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Secure Boot, signed kernel modules (for shitvidia), and the Shim - Why does the kernel need to support SB after the handover? Can a graphics coprocessor just run as a hotpluged module unsigned? (lemmy.world)

Asking about why the kernel needs to support secure boot on an individual system where I am not concerned about the hole punched by the nvidia kernel module. I'm concerned about the proprietary boot loader firmware that will never be maintained well. I'm not asking if it is a good idea in general or for most people.

Shit Gigabyte Aorus YE5 laptop doesn't support custom secure boot keys for PK in the bootloader. AVOID these thieves selling hardware you can't own.

Why can't an unsigned shitvidia kernel module run as a hotplugged device from user space without causing a problem with secure boot handover?

I can run Fedora with secure boot using the Microsoft 3rd party key. I just can't enable the shitvidia GPU. My primary use case is for LLM/stable diffusion, the GPU doesn't matter for graphics.

In my case here, I have a 16GBV 3080Ti paired with a 12 gen i7. The integrated graphics for the i7 are fine for all graphics operations I need. I got the GPU specifically for LLM stuff. The system memory is DDR5 and the GPU is DDR6. It is an optimus design, so it is a bit different than a desktop, but from what I've read, this is just a matter of thermal and power throttling features that are broken out for kernel controls that are not present in the desktop cards.

The bootloader issues are universal to all platforms that use UEFI. There are several documents available from the UEFI Consortium and NIST that cover the subject in detail and how to mitigate the problems.
