1797587 - Make nsSystemInfo return the CPU model name

Status: RESOLVED FIXED

(Core :: XPCOM, task)

Description

[Florian Quèze [:florian]]

I would like to be able to estimate our power use in the wild using Telemetry data. We already record how much CPU time is used. To convert this CPU time to an estimated power consumption in Wh, I would need the TDP (Thermal Design Power) of the user's CPU. I don't know of any way to access this information locally, so I think the best solution would be to record the CPU model name, and then on the server side convert that to the TDP using tables provided by the CPU manufacturers.
