From 2b5b3f9b698f8e5d6492763947231e7d9420d8da Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Wed, 8 Oct 2025 13:07:13 +0530 Subject: [PATCH] drm/amd/pm: Grant interface access after full init Allow access to user interfaces like sysfs/hwmon only after full initialization of the device. When device is part of XGMI hive and a reset is required during initialization, the inteface files will be created as part of minimal device initialization. Full initialization of the device will be done only after all devices in XGMI hive are probed and a reset is done together on all.
