ioaddr | Specifies the effective address returned by the iomem_att kernel service. |
The iomem_det kernel service releases memory-mapped I/O addressability. A call to the iomem_det kernel service must be made for every iomem_att call, with the address that iomem_att returned.
The iomem_det kernel service can be called from either the process or interrupt environment.
The iomem_det kernel service returns no return values.
The iomem_det kernel service is part of the Base Operating System (BOS) Runtime.
The iomem_att kernel service.
