[Intel-gfx] What happens if forcewake is not properly set

[Jaeyong Yoo]

Hello Daniel and the other maintainers,

I'm having some weird trouble while working on my small project.

For some reason, there is a chance that forcewake is not properly set, when
I'm reading some registers.

In that case, when values from registers (e.g., ring head, xxIMRs, .) are
sometimes 0 (I'm highly suspecting that they are not actually zero).

Is this could be the side-effect of forcewake-not-set?

 

Thanks,

JY
