2022-02-28iommu: Split struct iommu_opsLu Baolu1-4/+6
Move the domain specific operations out of struct iommu_ops into a new structure that only has domain specific operations. This solves the problem of needing to know if the method vector for a given operation needs to be retrieved from the device or the domain. Logically the domain ops are the ones that make sense for external subsystems and endpoint drivers to use, while device ops, with the sole exception of domain_alloc, are IOMMU API internals.

2021-04-16iommu: Streamline registration interfaceRobin Murphy1-3/+1
Rather than have separate opaque setter functions that are easy to overlook and lead to repetitive boilerplate in drivers, let's pass the relevant initialisation parameters directly to iommu_device_register().

2013-08-14iommu/fsl: Freescale PAMU driver and iommu implementation.Varun Sethi1-0/+1172
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.
