Subject: [PATCH v2 0/2] ACPI / EC: Tune suspend/resume speed using PM operations
Date: Fri, 29 Jul 2016 18:05:38 +0800	[thread overview]
Message-ID: <cover.1469785918.git.lv.zheng@intel.com> (raw)
In-Reply-To: <bd9df7ba491b33cfbaa46f4cc6a6325f74153e36.1469093001.git.lv.zheng@intel.com>

There are 2 improvements can be done to the EC driver to make system
suspend/resume faster:
1. Automatically use busy polling mode when noirq is entered
2. Disallow event handling (SCI_EVT/_Qxx) during suspend/resume period

This patchset achieves such performance tuning on top of a recent
workaround that creates ec_query_wq.

Lv Zheng (2):
  ACPI / EC: Add PM operations to tune polling mode efficiency
  ACPI / EC: Add PM operations to block event handling
