From 135ade0c6afccbe874bdda811201733e5b57c9bc Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Wed, 26 May 2021 11:14:21 +0300 Subject: [PATCH] habanalabs: prefer ASYNC device probing There is no dependency when probing multiple devices so indicate to the kernel that it can probe our devices in ASYNC fashion. This shortens insmod of the driver from ~2 minutes to 20 seconds on a system with 8 devices.
