From 03a1c08d003bd9354f522d45a6e3dcd529f409c2 Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Fri, 31 Aug 2018 16:54:12 -0400 Subject: [PATCH] drm/amdgpu: Clean up KFD init and fini Only initialize KFD once by moving amdgpu_amdkfd_init from amdgpu_pci_probe to amdgpu_init. This fixes kernel oopses and hangs when booting multi-GPU systems. Also removed some vestiges of KFD being its own module.
