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"; --- [PATCH v3 1/5] PM / sleep: Two flags for async suspend_noirq and [PATCH v3 2/5] PM / sleep: Asynchronous threads for resume_noirq [PATCH v3 3/5] PM / sleep: Asynchronous threads for resume_early [PATCH v3 4/5] PM / sleep: Asynchronous threads for suspend_noirq [PATCH v3 5/5] PM / sleep: Asynchronous threads for suspend_late drivers/base/power/main.c | 275 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++---------------------------- include/linux/pm.h | 2 ++ 2 files changed, 227 insertions(+), 50 deletions(-)
