Subject: [PATCH v3 0/5] Enabling the asynchronous threads for other phases
Date: Mon, 17 Feb 2014 14:19:09 +0800 [thread overview]
Message-ID: <1392617954-5292-1-git-send-email-chuansheng.liu@intel.com> (raw)
In-Reply-To: <y>
Hello,
This patch series are for enabling the asynchronous threads for the phases
resume_noirq, resume_early, suspend_noirq and suspend_late.
Just like commit 5af84b82701a and 97df8c12995, with async threads it will
reduce the system suspending and resuming time significantly.
With these patches, in my test platform, it saved 80% time in resume_noirq
phase.
Best Regards,
---
V2:
-- Based on Rafael's minor changes related to coding style, white space etc;
-- Rafael pointed out the v1 series break the device parent-children
suspending/resuming order when enabling asyncing, here using the
dev completion to sync parent-children order;
V3:
-- In patch v2 5/5, there is one missing "dpm_wait_for_children";
