Subject: [PATCH v1 0/4]mmc: enable eMMC4.41 new feature background operations and HPI
Date: Tue, 23 Nov 2010 16:43:09 +0800 [thread overview]
Message-ID: <20101123084309.GA17754@intel.com> (raw)
Hi,
These patches were enabled eMMC4.41 standard new feature: background
operations and HPI.
Since these two features are opertional, driver only enable for those
eMMC card which supports them.
HPI can interrupt both background operations and low priority foreground
operations. In these patches, only implemented using HPI to interrupt
background operations.
patch1: enable background operations feature for supported eMMC card.
patch2: let eMMC card do background operations when user reqeust queue
is idle. In this patch, also considered when driver added runtime power
management.
patch3: enable HPI feature for supported eMMC card.
patch4: use HPI to interrupt background operations if there is user
request(foreground operations).
Thanks
Chuanxiao
