Enumeration Type Documentation

◆ anonymous enum

anonymous enum

A list of all possible logical devices which may be supported by at least one of the Super I/O chips.

These values are used as index into the logical_device_table[i].devs array(s).

If you change this enum, you must also adapt the logical_device_table[] array and MAX_LOGICAL_DEVICES!

TODO.

This table should contain all possible entries for any of the supported Super I/O chips, even if some of them don't have the respective logical devices. That will be handled correctly by our code.

The LD_FOO entries are device markers which tell you the type of the logical device (e.g. whether it's a floppy disk controller or a serial port etc.).

Before using pnp_dev_info[] in pnp_enable_devices() these markers have to be replaced with the real logical device IDs of the respective Super I/O chip. This is done in enable_dev().

TODO: FDC, PP, SP1, SP2, and KBC should work, the rest probably not (yet).
