These interfaces are obsolete. Use ddi_regs_map_setup(9F) instead of ddi_map_regs(). Use ddi_regs_map_free(9F) instead of ddi_unmap_regs().
Pointer to the device's dev_info structure.
Register set number.
Pointer to the base kernel address of the mapped region (set on return).
Offset into register space.
Length to be mapped.
Pointer to the device's dev_info structure.
Register set number.
Pointer to the base kernel address of the region to be unmapped.
Offset into register space.
Length to be unmapped.
The ddi_map_regs() function maps in the register set given by rnumber. The register number determines which register set will be mapped if more than one exists. The base kernel virtual address of the mapped register set is returned in kaddrp. offset specifies an offset into the register space to start from and len indicates the size of the area to be mapped. If len is non-zero, it overrides the length given in the register set description. See the discussion of the reg property in sbus(4) and for more information on register set descriptions. If len and offset are 0, the entire space is mapped.
The ddi_unmap_regs() function undoes mappings set up by ddi_map_regs(). This is provided for drivers preparing to detach themselves from the system, allowing them to release allocated mappings. Mappings must be released in the same way they were mapped (a call to ddi_unmap_regs() must correspond to a previous call to ddi_map_regs()). Releasing portions of previous mappings is not allowed. rnumber determines which register set will be unmapped if more than one exists. The kaddrp, offset and len specify the area to be unmapped. kaddrp is a pointer to the address returned from ddi_map_regs(); offset and len should match what ddi_map_regs() was called with.
The ddi_map_regs() function returns:
on success.
These functions can be called from user, interrupt, or kernel context.
