[Feature Request] get a list of the drivers used

[theLOICofFRANCE]

Hi @didrocks,

It would be very interesting to know the drivers of the most used hardware, this could help to optimize the kernel. It would thus be necessary to take into account simply this: lspci -vvnn | egrep "Kernel driver|Kernel modules" | cut -d: -f2 | uniq

This would be very interesting for Linux kernel developers and people who compile custom kernels.

Thanks. Best regards,

Hey @HacKurx,

It’s indeed an interesting idea and should be easy to do as a first contribution for anyone interested. Just out of interest, are you going to use those data yourself?

[theLOICofFRANCE]

I'm going to use his data to disable drivers that are no longer in use. This has several advantages such as reducing the kernel size and reducing the attack surface (old drivers are sometimes bad maintained).

Currently, I maintain a driver list on my side to compile custom small kernels that offer maximum hardware compatibility.

And I'm not the only one who needs his data. 2 examples:

1. Base pour connaitre le matériel qui marche sous Linux
2. src_platform_clip-hardware

For example, I got the most used modules from the 2nd link, here is the result:

Thanks to this feedback, I also know which driver I shouldn't disable and also where I have to be reactive to fix bugs because a lot of equipment is concerned.

It’s indeed an interesting idea and should be easy to do as a first contribution for anyone interested.

My free time and my English are limited but if my changes are merged upstream then I'm willing to go for it.

Sure. please give it a try! Instead of egrep and uniq. Please try to use go functions to do this. I’m sure you find a lot of code in ubuntu-report helping you with that. Please think about adapating the tests, but that shouldn’t be too much to do.

[theLOICofFRANCE]

Sure. please give it a try!

I quickly started on fb581db. I need to see how to compile and test the code. I've never touched the Go programming language ^^

@singhvarun9641 Do you take us for fools?

@didrocks I joined the HardenedBSD team, therefore I lost the interest of this request. Sorry and thanks for everything.
