Commit <421be3ee36a4> ("drm/rockchip: Refactor IOMMU initialisation") has
refactored rockchip_drm_init_iommu() to pass a device that the domain is
allocated for. Replace iommu_domain_alloc() with
iommu_paging_domain_alloc() to retire the former.Signed-off-by: Lu Baolu <baolu...@linux.intel.com> Reviewed-by: Jason Gunthorpe <j...@nvidia.com> Link: https://lore.kernel.org/r/20240610085555.88197-19-baolu...@linux.intel.com --- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c index 44d769d9234d..11e5d10de4d7 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c @@ -103,13 +103,17 @@ static int rockchip_drm_init_iommu(struct drm_device *drm_dev) struct rockchip_drm_private *private = drm_dev->dev_private; struct iommu_domain_geometry *geometry; u64 start, end; + int ret; if (IS_ERR_OR_NULL(private->iommu_dev)) return 0; - private->domain = iommu_domain_alloc(private->iommu_dev->bus); - if (!private->domain) - return -ENOMEM; + private->domain = iommu_paging_domain_alloc(private->iommu_dev); + if (IS_ERR(private->domain)) { + ret = PTR_ERR(private->domain); + private->domain = NULL; + return ret; + } geometry = &private->domain->geometry; start = geometry->aperture_start; -- 2.34.1
