From 7af1e0aceeb321cbc90fcf6fa0bec8870290377f Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Fri, 8 Sep 2023 13:10:45 -0700 Subject: dmaengine: idxd: add wq driver name support for accel-config user tool With the possibility of multiple wq drivers that can be bound to the wq, the user config tool accel-config needs a way to know which wq driver to bind to the wq. Introduce per wq driver_name sysfs attribute where the user can indicate the driver to be bound to the wq. This allows accel-config to just bind to the driver using wq->driver_name.
