[Intel-gfx] [PATCH] drm/i915: Flush the PTEs after updating them before suspend

2014-09-25 Thread Chris Wilson
As we use WC updates of the PTE, we are responsible for notifying the hardware when to flush its TLBs. Do so after we zap all the PTEs before suspend (and the BIOS tries to read our GTT). Fixes a regression from commit 828c79087cec61eaf4c76bb32c222fbe35ac3930 Author: Ben Widawsky Date: Wed Oct

As we use WC updates of the PTE, we are responsible for notifying the hardware when to flush its TLBs. Do so after we zap all the PTEs before suspend (and the BIOS tries to read our GTT). Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=82340 Tested-by: ming@intel.com Signed-off-by: Chri
