From 4a9c6e2cdf2b4128f5204b9cf14e3a788a8511df Mon Sep 17 00:00:00 2001 From: Tal Cohen Date: Tue, 18 Oct 2022 17:35:06 +0300 Subject: [PATCH] habanalabs: no consecutive err when user context is enabled Consecutive error protects a device reset loop from being triggered due to h/w issues and enters the device into an unavailable state. When user may cause the error, an unavailable state will prevent the user from running its workloads. The commit prevents entering consecutive state when a user context is enabled.
