KnRegisterPhyMem()

This function is declared in the coresrv/io/mmio.h file.

Retcode KnRegisterPhyMem(rtl_uint64_t addr, rtl_size_t size, Handle *outRid);

This function registers a memory area with the specified size (in bytes) and beginning at the address addr.

If registration is successful, the handle assigned to the memory area will be passed to the outRid parameter, and the function will return rcOk.

The address addr must be page-aligned, and the specified size must be a multiple of the page size.

For a usage example, see KnIoMapMem().

If a memory area is no longer being used, it must be freed by using the KnIoClose() function.
