From 1ad5bdc28bafa66db0f041cc6cdd278a80426aae Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 11 Dec 2024 09:56:01 -0600 Subject: [PATCH 1257/5403] drm/amd: Require CONFIG_HOTPLUG_PCI_PCIE for BOCO If the kernel hasn't been compiled with PCIe hotplug support this can lead to problems with dGPUs that use BOCO because they effectively drop off the bus. To prevent issues, disable BOCO support when compiled without PCIe hotplug.
