uvcvideo & iwl-mvm-rs & ASPM & psmouse

As I am trying to clear any possible errors from the system to reduce latency and improve overal performace I can't find a solution to fix a problem with the thermal.

Everything is functioning, although I feel that the trackpad, isnt doing it's best (in design terms) I know it can be better.

Here are some snapshots

[root@root ~]$ dmesg | grep -i fail
[    0.661368] acpi PNP0A08:00: _OSC failed (AE_SUPPORT); disabling ASPM
[    2.964641] uvcvideo: Failed to initialize entity for entity 6
[    2.964642] uvcvideo: Failed to register entities (-22).
[    3.074757] thermal thermal_zone2: failed to read out thermal zone (-61)

1. Mode information on the issuses ASPM

2. more information on the vcvideo

[    3.500730] psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0

I can't find the right firmware - if so, I would like to write it but I dont know where to start!

I've installed my first linux(redhat) in 1999 and configured as a dhcp server.
Since i am an avid user and graphic artist at heart.

I've also updated to 5.2.1-arch1-1-ARCH but I still have the same fails.

Re: uvcvideo & iwl-mvm-rs & ASPM & psmouse

Most of these are of informal nature, and should not have any effect on general system stability/performance or latency. 

Sometimes hardware devices claim to support more features than they actually do and the kernel will log an error trying to initialize them. The ASPM errors are likely limited to a single device that simply isn't ASPM capable that can happen (probably some realtek  chip because it's always them...). Thermal zone readout failures could be due to lacking a sensor, or the BIOS preventing access to the sensor data.

The touchpad message tells you that there are multiple bus implementations to query the device with, and depending on if you actually have an issue here (what does "i know it can be better" mean exactly? Do you have an actual issue?) this might be something you can play with, using the kernel parameter mentioned.

All in all, none of these are "real" errors you should be worrying about, and they are unlikely to be fixed by kernel updates (one thing you could try is updating your UEFI/BIOS and seeing whether these fix the detection issues of the kernel)

I'm  a designer, i feel maybe the sensitivity (on touch) is too high -as when I compare it to win based firmware (personal opinion).
like when you touch just a little by mistake and it changes the cursor, the screen or anything you work on. (i hope it makes sense)

Overal - I've managed to make it work 99% (as the 1% i can't get it to lock on suspend with lightdm gtk base)

But thanks for sharing your opinion on this. Someone with better experience knows.
