From: Lijo Lazar Date: Wed, 8 Oct 2025 07:37:13 +0000 (+0530) Subject: drm/amd/pm: Grant interface access after full init X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2b5b3f9b698f8e5d6492763947231e7d9420d8da;p=thirdparty%2Flinux.git 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.
