Hello getting into Linux driver development.
My idea: pass an RFID card to an ESP32 to authenticate sudo instead of typing a password. The secret lives on the card, not the machine. Is this a good project to learn linux driver development? ? Thanks
Hey everyone! So my eyes are currently set in Computer Engineering for College.. I was browsing for the possible jobs I can choose that are versatile and can actually be stable even for a decade.. I currently don't want to pursue any AI or Robot related jobs.. but while I was browsing, I found out that you can be a Kernel Developer/Linux Systems dev after Comp En. I grew interested in it because: it sounds fun, and it gives a challenge for me...knowing I'll fail miserably just to get there. I'm still a complete beginner to the tech industry.. but for me to be sure if I should get that job in the future, I just wanted to ask this in this subreddit.. so yeah! You can also humble me if my thoughts sound childish or what, lol.
Having a ThinkPad P1 Gen 7 with Meteor Lake, I’m seeing crashes with both i915 and xe. I’ve reported this upstream to the kernel/DRM folks.
Kernel 6.19.14 was rock solid here. Is anyone else seeing regressions this severe?
With xe, the system can crash within ~30 minutes, which is already bad enough. But now I’m also seeing i915 blow up? WTF?

Hi folks.
I am trying to get into kernel with buildroout using my Zero 3, but can't for the life of me make it work. I would be grateful if someone more experienced could point me into right direction.
According to recommendations the host is Ubuntu 22, but no matter what I do I end up with something like this:

I have tried:
I've been adding newer kernels to my main desktop running Linux Mint 22.3 (mate). Thing have been smooth with no odd effects until recently. I've been using mainline install tool for more than a year but run into a recent problem. My current kernel (6.19.10-061910-generic) I guess is the last successful install.
I think somehow parameters used by runparts in the kernel install process are failing. That's my guess. Here is the error log dumped from mainline.

E: The package linux-image-unsigned-7.0.1-070001-generic needs to be reinstalled, but I can't find an archive for it.
I've tried the process with kernels prior to 7.0.1 this is just the most recent one attempted. Reinstalling as it suggest ends up with you going in circles and having the same error. I think an environment variable that hold a path is set to empty. That's my theory. Anyone have any suggestions to resolve this fault. Thanks in advance!
