From: Jeff McGee <jeff.mcgee@xxxxxxxxx> 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.
