The genkex command extracts the list of kernel extensions currently loaded onto the system and displays the address, size, and path name for each kernel extension in the list.
For kernel extensions loaded onto the system, the kernel maintains a linked list consisting of data structures called loader entries. A loader entry contains the name of the extension, its starting address, and its size. This information is gathered and reported by the genkex command.
To generate the list of loaded kernel extensions, enter:
genkex
The genkld command, genld command.
