From 9806eb5c79579e200f88660e043706eb490547e6 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Fri, 6 Aug 2021 10:38:37 -0700 Subject: dmaengine: idxd: set descriptor allocation size to threshold for swq Since submission is sent to limited portal, the actual wq size for shared wq is set by the threshold rather than the wq size. When the wq type is shared, set the allocated descriptors to the threshold.
