The iommu subsystem no longer relies on bus for operations. So iommu_domain_alloc() interface is no longer relevant. A new helper named iommu_paging_domain_alloc() was introduced in the iommu subsystem as a replacement of iommu_domain_alloc(). This helper relies on the device for IOMMU API use instead of the bus. The replacement work started from this series: https://lore.kernel.org/linux-iommu/20240610085555.88197-1-baolu.lu@linux.intel.com/ Several patches have already been merged into the mainline kernel, but we've decided to route all remaining ones through the subsystem tree. Change log: v2: - Patch 3/3: use dev->dev.parent as the input for iommu_paging_domain_alloc(), suggested by Thierry Reding. https://lore.kernel.org/linux-iommu/qyvyd2ftebjlgmzyayfvxsqa64c4wgx7keix3a6eexdspbvawy@a5ffnm5h5tgp/ v1: - https://lore.kernel.org/linux-iommu/20240812071034.9443-1-baolu.lu@linux.intel.com/ Lu Baolu (3): drm/nouveau/tegra: Use iommu_paging_domain_alloc() drm/rockchip: Use iommu_paging_domain_alloc() drm/tegra: Use iommu_paging_domain_alloc() drivers/gpu/drm/nouveau/nvkm/engine/device/tegra.c | 4 ++-- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 10 +++++++--- drivers/gpu/drm/tegra/drm.c | 5 +++-- 3 files changed, 12 insertions(+), 7 deletions(-) -- 2.34.1
