[PATCH v2 0/2] Base enablement of IOMMU debugfs support
These patches create a top-level function to create a debugfs directory for the IOMMU, under which drivers may create and populate-specific directories for their device internals. Patch 1: general IOMMU enablement Patch 2: basic AMD enablement to demonstrate linkage with patch 1 Introduce a new Kconfig parameter IOMMU_DEBUG to globally allow or disallow debugfs code to be built. Changes since v1: - Remove debug cruft - Remove cruft produced by design change - Change the lock to a mutex - Coding style fixes - Add a comment to document the framework --- Gary R Hook (2): iommu - Enable debugfs exposure of the IOMMU iommu/amd: Add basic debugfs infrastructure for AMD IOMMU drivers/iommu/Kconfig | 11 +++ drivers/iommu/Makefile|2 + drivers/iommu/amd_iommu_debugfs.c | 45 + drivers/iommu/amd_iommu_init.c|7 +++- drivers/iommu/amd_iommu_proto.h |8 - drivers/iommu/amd_iommu_types.h |3 ++ drivers/iommu/iommu-debugfs.c | 58 + include/linux/iommu.h |4 +++ 8 files changed, 135 insertions(+), 3 deletions(-) create mode 100644 drivers/iommu/amd_iommu_debugfs.c create mode 100644 drivers/iommu/iommu-debugfs.c -- Signature
