Phoronix: Linux 6.5 Ready To Ship With Initial USB4 v2, More WiFi 7, AMD P-State EPP Default & More

Barring any last minute problems from coming up, the Linux 6.5 kernel is expected to be released as stable tomorrow, 27 August. Here's a reminder about all of the great changes and new features with this next kernel version, which is especially heavy on exciting additions for Intel and AMD Linux users...

I hope changing the refresh rate on eDP panels finally works now. So far it required injecting a custom EDID into the kernel because the driver would lock to the preferred refresh rate and leave it at that.

Got more details on how to do this? E.g. Github issue link?

I wonder if the fan control in the final version 6.5 will work for RDNA3 cards, or is it a corectrl/LACT issue?

AMD dev said it needed new kernel interface, as it's entirely firmware controlled since RDNA3. My worst case guess is it might take years.

isn't that only for the reference cards?

Manual fan control is no longer available on RDNA3 GPUs. You can only adjust the fan curve. That does not fit into the existing hwmon manual fan control interface so a new interface would need be developed to expose it to users. The programming information is exposed in the driver, it's just not yet hooked up to an interface for user control.

Mostly just trying to understand whether it's something we can fit into the existing hwmon infrastructure or if we need to come up with a new interface, be it an addition to hwmon or an AMD specific interface in amdgpu.

luckily the fan curve on my powercolor hellhound 7900 xt isn't awful and with the oversized cooler it runs extremely cool i don't need to mess with it.

USB4 v2? I hope it has backwards compatibility so I don't have to replace my mouse and keyboard.
