From 63573eb7ba3d1bdc1db25fe79314609a4189a306 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Thu, 4 Jul 2013 11:02:07 -0700 Subject: [PATCH] drm/i915: debugfs entries for [e]LLC To make users life a little easier figuring out what they have on their system. Ideally, I'd really like to report LLC size, but it turned out to be a bit of a pain. Maybe I'll revisit it in the future.
