Description: RO. Card default power limit (default TDP setting).

platforms.

Date and kernel version will need updating throughout I think.
But why I am here actually is to ask if there are plans to make
intel_gpu_top support this? It would be nice to have since it reports power
for integrated.
There were no plans but now Riana has an IGT patch series which exposes a
unified inteface for rapl/hwmon (igfx/dgfx):
https://patchwork.freedesktop.org/series/108185/
So perhaps we can either have intel_gpu_top use this IGT lib or if it
doesn't, copy some functions to intel_gpu_top.
Looks promising and would be nice yeah.
On the practicalities, first thing which comes to mind that probably it
would need to be a separate library like igt_perf and igt_device_scan,
since so far we have avoided linking intel_gpu_top with the whole lib_igt.
