Questions about interrupt command register(ICR)

[BoJ]

Hi,

I'm a graduate student newly working on Intel CPU.

Could you please tell me that how is the interrupt command register accessed?

And is the access to this register a priviledge operation?

Hello BoJ, 

I noticed that you are using a server processor (Intel® Xeon® Gold 6330 Processor), so I will refer you to the server forums so you can get proper support.

Thanks for your comprehension.
