Description ZhaoShengyan 2013-12-09 06:46:33 UTC 
Test Env:
------------------------------------
Platform:               HSW
Arch:                   x86
OS:                     Fedora 19
Xserver:                (server-1.14-branch)xorg-server-1.14.4.901
Xf86_video_intel:               (master)2.99.906
Kernel:                  kernel-3.12.2_20131203+-2.x86_64


Reproduced Steps:
------------------------------------
1. Booting kernel with parameter i915.i915_enable_sr=1.
2. Connect dual display with HDMI cable.
3. xinit &
4. cat /sys/kernel/debug/dri/0/i915_sr_status

The expected phenomenon should be: 
self-refresh: disabled with dual display. However, we got self-refresh enabled with dual display.




Reproduced Rate:
------------------------------------

It's not a bug. HSW+ supports LP1+ watermarks even with multiple displays.
