--- Comment #16 from Lionel Landwerlin <lionel.g.landwerlin at linux.intel.com> ---
I didn't see a fix go into i915 (I could have missed it).
But regardless I don't think reading the register directly is a good idea.

We have some work in the pipe to enable powergating per context and that I'm
sure will lead to different result depending on when the register are read.

Should we have a kernel context emit a few MI_STORE_REGISTER_MEM and read back
the result? Or is that overkill?
