drivers: iommu: move to a dedicated folder Create a dedicated folder for iommu drivers, and move the base iommu implementation over there. Grouping the various iommu drivers in a single location will help finding similar problems shared by different platforms, so they could be solved once, in the iommu framework, instead of solved differently (or duplicated) in each driver.

iommu: Add event tracing feature to iommu Add tracing feature to iommu to report various iommu events. Classes iommu_group, iommu_device, and iommu_map_unmap are defined. iommu_group class events can be enabled to trigger when devices get added to and removed from an iommu group. Trace information includes iommu group id and device name. iommu:add_device_to_group iommu:remove_device_from_group iommu_device class events can be enabled to trigger when devices are attached to and detached from a domain. Trace information includes device name. iommu:attach_device_to_domain iommu:detach_device_from_domain iommu_map_unmap class events can be enabled to trigger when iommu map and unmap iommu ops. Trace information includes iova, physical address (map event only), and size. iommu:map iommu:unmap Signed-off-by: Shuah Khan <shuah.kh@samsung.com> Signed-off-by: Joerg Roedel <joro@8bytes.org>

iommu: Add sysfs support for IOMMUs IOMMUs currently have no common representation to userspace, most seem to have no representation at all aside from a few printks on bootup. There are however features of IOMMUs that are useful to know about. For instance the IOMMU might support superpages, making use of processor large/huge pages more important in a device assignment scenario. It's also useful to create cross links between devices and IOMMU hardware units, so that users might be able to load balance their devices to avoid thrashing a single hardware unit. This patch adds a device create and destroy interface as well as device linking, making it very lightweight for an IOMMU driver to add basic support. IOMMU drivers can provide additional attributes automatically by using an attribute_group. The attributes exposed are expected to be relatively device specific, the means to retrieve them certainly are, so there are currently no common attributes for the new class created here.

iommu: Implement common IOMMU ops for DMA mapping Taking inspiration from the existing arch/arm code, break out some generic functions to interface the DMA-API to the IOMMU-API. This will do the bulk of the heavy lifting for IOMMU-backed dma-mapping. Since associating an IOVA allocator with an IOMMU domain is a fairly common need, rather than introduce yet another private structure just to do this for ourselves, extend the top-level struct iommu_domain with the notion. A simple opaque cookie allows reuse by other IOMMU API users with their various different incompatible allocator types.

iommu: introduce generic page table allocation framework This patch introduces a generic framework for allocating page tables for an IOMMU. There are a number of reasons we want to do this: - It avoids duplication of complex table management code in IOMMU drivers that use the same page table format - It removes any coupling with the CPU table format (and even the architecture!) - It defines an API for IOMMU TLB maintenance Tested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Will Deacon <will.deacon@arm.com>

iommu/arm-smmu: Add initial driver support for ARM SMMUv3 devices Version three of the ARM SMMU architecture introduces significant changes and improvements over previous versions of the specification, necessitating a new driver in the Linux kernel. The main change to the programming interface is that the majority of the configuration data has been moved from MMIO registers to in-memory data structures, with communication between the CPU and the SMMU being mediated via in-memory circular queues. This patch adds an initial driver for SMMUv3 to Linux. We currently support pinned stage-1 (DMA) and stage-2 (KVM VFIO) mappings using the generic IO-pgtable code.

iommu/rockchip: rk3288 iommu driver The rk3288 has several iommus. Each iommu belongs to a single master device. There is one device (ISP) that has two slave iommus, but that case is not yet supported by this driver. At subsys init, the iommu driver registers itself as the iommu driver for the platform bus. The master devices find their slave iommus using the "iommus" field in their devicetree description. Since each slave iommu belongs to exactly one master, their is no additional data needed at probe to associate a slave with its master. An iommu device's power domain, clock and irq are all shared with its master device, and the master device must be careful to attach from the iommu only after powering and clocking it (and leave it powered and clocked before detaching). Because their is no guarantee what the status of the iommu is at probe, and since the driver does not even know if the device is powered, we delay requesting its irq until the master device attaches, at which point we have a guarantee that the device is powered and clocked and we can reset it and disable its interrupt mask. An iommu_domain describes a virtual iova address space. Each iommu_domain has a corresponding page table that lists the mappings from iova to physical address. For the rk3288 iommu, the page table has two levels: The Level 1 "directory_table" has 1024 4-byte dte entries. Each dte points to a level 2 "page_table". Each level 2 page_table has 1024 4-byte pte entries. Each pte points to a 4 KiB page of memory. An iommu_domain is created when a dma_iommu_mapping is created via arm_iommu_create_mapping. Master devices can then attach themselves to this mapping (or attach the mapping to themselves?) by calling arm_iommu_attach_device(). This in turn instructs the iommu driver to write the page table's physical address into the slave iommu's "Directory Table Entry" (DTE) register. In fact multiple master devices, each with their own slave iommu device, can all attach to the same mapping. The iommus for these devices will share the same iommu_domain and therefore point to the same page table. Thus, the iommu domain maintains a list of iommu devices which are attached. This driver relies on the iommu core to ensure that all devices have detached before destroying a domain. v6: - add .add/remove_device() callbacks. - parse platform_device device tree nodes for "iommus" property - store platform device pointer as group iommudata - Check for existence of iommu group instead of relying on a dev_get_drvdata() to return NULL for a NULL device. v7: - fixup some strings. - In rk_iommu_disable_paging() # and % were reversed.

iommu/fsl: Freescale PAMU driver and iommu implementation. Following is a brief description of the PAMU hardware: PAMU determines what action to take and whether to authorize the action on the basis of the memory address, a Logical IO Device Number (LIODN), and PAACT table (logically) indexed by LIODN and address. Hardware devices which need to access memory must provide an LIODN in addition to the memory address. Peripheral Access Authorization and Control Tables (PAACTs) are the primary data structures used by PAMU. A PAACT is a table of peripheral access authorization and control entries (PAACE).Each PAACE defines the range of I/O bus address space that is accessible by the LIOD and the associated access capabilities. There are two types of PAACTs: primary PAACT (PPAACT) and secondary PAACT (SPAACT).A given physical I/O device may be able to act as one or more independent logical I/O devices (LIODs). Each such logical I/O device is assigned an identifier called logical I/O device number (LIODN). A LIODN is allocated a contiguous portion of the I/O bus address space called the DSA window for performing DSA operations. The DSA window may optionally be divided into multiple sub-windows, each of which may be used to map to a region in system storage space. The first sub-window is referred to as the primary sub-window and the remaining are called secondary sub-windows. This patch provides the PAMU driver (fsl_pamu.c) and the corresponding IOMMU API implementation (fsl_pamu_domain.c). The PAMU hardware driver (fsl_pamu.c) has been derived from the work done by Ashish Kalra and Timur Tabi.
