Issues with Intel Arc GPU on Arch Linux (low performance, power&temp monitor, and LAPAC71H issues)

[Crimson-Hawk]

The title says it all. I own a laptop (Intel NUC LAPAC71H) with Intel Arc A730M, and I found it impossible to monitor the current GPU power. The only tool available to monitor the GPU was via the intel-gpu-tools package here (upstream here) which only offered GPU usage and clock speeds.

Steps to reproduce the issue:

1. Install Arch Linux 
2. Update with "sudo pacman -Syyuu"
3. Install KDE
4. Install Wayland
5. Install intel-gpu-tools package (sudo pacman -S intel-gpu-tools)
6. run "sudo intel_gpu_top" in terminal

Secondly, I found that the performance of the GPU is significantly lower than Windows (measured with MangoHUD and MSI afterburner, respectively), especially with Cyberpunk 2077 even when taking into account the translation overhead. The discrete GPU is selected and the game is ran with the latest version of proton and operating system.

Steps to reproduce the issue:

1. Install Arch Linux 
2. Update with "sudo pacman -Syyuu"
3. Install KDE
4. Install Wayland
5. Install steam from multilib package list
6. Install MangoHUD
7. Install Cyberpunk 2077
8. Launch Cyberpunk 2077 with the latest proton version and MangoHUD enabled

Lastly, the GPU power in the system DOES NOT reach the advertised 80-120W. Instead, it is capped at 75 watts even on performance mode set in intel NUC center software, even when the temperatures are under perfect control and under heavy load. I found this problem while in Windows and was unable to solve it.

Steps to reproduce the issue:

1. Install Windows 22H2
2. Install driver version 31.0.101.5084/31.0.101.5122 (WHQL Certified) 
3. Install the aforementioned NUC control software
4. Monitor the GPU power with Intel Arc Control

CONCLUSION: I would like the Intel Arc driver team to acknowledge the aforementioned issue and try to implement the following:

1. Add a way to monitor the power draw and temperature of Intel Arc GPUs in Arch Linux
2. Increase the TDP of the Intel Arc A730M in the laptop LAPAC71H to the advertised 80-120W (preferably through a firmware update)

Thanks to anyone who had the time to read this, or made any contributions to resolve the problem
