Note to self: do not buy any #HP #Omen any time soon for #Linux use:

"[…] I *DO* have to warn you that fan control for both the GPU and the CPU is done solely and passively by the embedded controller, and not the #kernel -- and that is problematic.

On my laptop (8BAD), it is pretty clear that the provided/passive fan curve table is broken. The fans run slower than what they should be, which results in potential overheating UNLESS […]"

I disliked EliteBook lineup already enough that have not used HP since 2011 ;-)

@kernellogger but isn't this what you usually want? Base functionality offered by the device's firmware, and higher speeds available as soon as a driver takes over – as far as feasible with things as slow as thermal mass, a userland one?

@funkylab

Leaving Linux aside for a moment:

Do you want to live in a world where even under the Windows you can only utilize the full potential of your hardware if you install some vendor tool that sooner or later is likely to stop working after a windows update or version upgrade? Or sooner or later likely will have a known security vulnerability the vendor does not fix because the laptop is out of support?

I do not.

@kernellogger I have some stories. One of their product leads called me a wizard to my face once. I don't see this as a compliment.

@kernellogger not sure I understand the problem here; so we have a device that "half-works" on a stock Linux (just as on a stock Windows). So, all that's missing here is an upstreamed driver into thermald? Just like most thinkpads have one that was manually written by someone, some time after it hit the market?

@funkylab

Yes, there were some Thinkpads that had a similar problem (some X Carbons five or ten years ago IIRC? but there might have been more). But overall these things are the exception, not the norm *as far as I know*. At least when it comes to such drastic penalties when not running some vendor tool/driver.

@vathpela

🥴

Makes me wonder how you called them in your head, as apparently they did stupid things beforehand when designing some machines that lead to this.

@kernellogger in that case it was actually because I was able to re-spin installation isos (on usb sticks) in realtime to implement relatively minor bug workarounds (on an in person test day), which apparently takes a different vendor days.

@kernellogger the real story here is that people just do not understand ADHD.

@vathpela @kernellogger Oh I don't know, I'd take 'Wizard' as a complement normally!

@penguin42 @kernellogger it was weirdly dismissive.

@kernellogger oh, but the bug in question was if we did a read() too big on a CD the watchdog fired before the buffer filled.

@kernellogger I forgot about the CD burner aspect.
