From 20dca37a20f90762df13efd0e0ec97002b6a89f2 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 17 Jun 2015 15:50:13 -0700 Subject: [PATCH] i965/gen9: Don't use encrypted MOCS On gen9+ MOCS is an index into a table. It is 7 bits, and AFAICT, bit 0 is for doing encrypted reads. I don't recall how I decided to do this for BXT. I don't know this patch was ever needed, since it seems nothing is broken today on SKL. Furthermore, this patch may no longer be needed because of the ongoing changes with MOCS setup. It is what is being used/tested, so it's included in the series. The chosen values are the old values left shifted. That was also an arbitrary choice. v2: Use shift in MOCS to make it clear what we're doing.
