STRUCT UIO_MEM(9)                 Device drivers infrastructure                 STRUCT UIO_MEM(9)



NAME
       struct_uio_mem - description of a UIO memory region

SYNOPSIS
       struct uio_mem {
         const char * name;
         phys_addr_t addr;
         resource_size_t size;
         int memtype;
         void __iomem * internal_addr;
         struct uio_map * map;
       };

MEMBERS
       name
           name of the memory region for identification

       addr
           address of the device's memory (phys_addr is used since addr can be logical, virtual,
           or physical & phys_addr_t should always be large enough to handle any of the address
           types)

       size
           size of IO

       memtype
           type of memory addr points to

       internal_addr
           ioremap-ped version of addr, for driver internal use

       map
           for use by the UIO core only.
