From 96f75f9594466f92b10873cc3a49267cfe15ee49 Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Wed, 14 May 2025 17:00:46 -0400 Subject: drm/amdkfd: allow compute partition mode switch with cgroup exclusions The KFD currently bars a compute partition mode switch while a KFD process exists. Since cgroup excluded devices remain excluded for the lifetime of a KFD process and user space is able to mode switch single devices, allow users to mode switch a device with any running process that has been cgroup excluded from this device.
