From 3880d8e3c6ef2797900d5a437b705afe9baa815f Mon Sep 17 00:00:00 2001 From: Zhu Lingshan Date: Tue, 29 Oct 2024 16:46:34 +0800 Subject: [PATCH] amdkfd: find_process_by_mm always return the primary context Up until this commit, the kfd multiple contexts feature has not been fully implemented in mainline kernel yet. For backawrd compatibility, not break existing use cases, this commit changes function find_process_by_mm, let it always return the primary kfd_process.
