| |
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
