[Intel-gfx] [PATCH 0/3] Export GT config attributes

[jeff.mcgee at intel.com]

From: Jeff McGee <jeff.mcgee at intel.com>

The motivation for this change is that fusing can be used to create
multiple slice, subslice, and EU configuration within the same PCI
ID. CHV is the first such device to do this and thus make an ID-based
lookup table approach unreliable. The best solution is for the kernel
to determine the precise config from fuse registers and share the
required information with userspace. Moving to this approach has the
added benefit of reducing the number of static parameters that
userspace must maintain for current and future devices.

I'll be posting the libdrm and igt components next. I'm in the
process of collecting userspace support for this new interface.
I think the basic idea here is clear. With regards to which
attributes should be included, I am just starting with these 4. I can
add or remove attributes based on the feedback from userspace.
Please provide any comments. Thanks
