Rodriguez" List-Id: iommu@lists.linux-foundation.org We need to ensure amd iommu v2 initializes before driver uses such as drivers/gpu/drm/amd/amdkfd/kfd_module.c, to do this make its init routine a subsys_initcall() which ensures its load init is called first than modules when built-in. Signed-off-by: Luis R. Rodriguez --- Can someone test if this patch enables both CONFIG_AMD_IOMMU_V2 and CONFIG_HSA_AMD to be =y (built-in) without any conflicts ? drivers/iommu/amd_iommu_v2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iommu/amd_iommu_v2.c b/drivers/iommu/amd_iommu_v2.c index 56999d2fac07..60df645b9927 100644 --- a/drivers/iommu/amd_iommu_v2.c +++ b/drivers/iommu/amd_iommu_v2.c @@ -1004,5 +1004,5 @@ static void __exit amd_iommu_v2_exit(void) destroy_workqueue(iommu_wq); } -module_init(amd_iommu_v2_init); +subsys_initcall(amd_iommu_v2_init); module_exit(amd_iommu_v2_exit); -- 2.7.2
