Subject: [PATCH] intel: Export GT config attributes
Date: Thu, 18 Dec 2014 12:12:32 -0600	[thread overview]
Message-ID: <1418926353-10871-1-git-send-email-jeff.mcgee@intel.com> (raw)

From: Jeff McGee <jeff.mcgee@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.

The associated kernel patch has been posted to intel-gfx list (no
archive link yet). I'm trying to collect feedback from userspace
which I hope will be interested in adopting some form of this
interface. I am starting with these 4 attributes, but we can add or
remove them according to the userspace needs. Please provide any
comments. Thanks
