From c52ca478233c172b2d322b5241d6279a8661cbba Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Tue, 21 Jan 2020 16:44:05 -0700 Subject: dmaengine: idxd: add configuration component of driver The device is left unconfigured when the driver is loaded. Various components are configured via the driver sysfs attributes. Once configuration is done, the device can be enabled by writing the device name to the bind attribute of the device driver sysfs. Disabling can be done similarly. Also the individual work queues can also be enabled and disabled through the bind/unbind attributes. A constructed hierarchy is created through the struct device framework in order to provide appropriate configuration points and device state and status. This hierarchy is presented off the virtual DSA bus. i.e. /sys/bus/dsa/...
