Hello Ville,
I tested your patch: "commit 2d3d111a8f34606469e589d3491c9a64f62310b8",
With this commit + V47 BIOS+ BSW B1 CPU+ FAB2 board,
I can continually execute S3 command more than 5 cycles, feedback
i915_pm_resume_early message.-----------attach dmesg log:
ww39.2_patch_s3_dmesg.log
While double-check with kernel: tag drm-intel-nightly 2014-11-21, I only can do
S3 2 or 3 times, then IP address unavailable, S3 command fail to execute with
"resource temporary unavailable" message.
attach two dmesg log: WW39.2_v47_s3_3rd_Resume_dmesg1.log,
WW39.2_v47_s3_2nd_Resume_dmesg2.log</pre>
