Subject: [PATCH 4/4] dmidecode: add dmi sysfs support
|
|
|
3ea658 |
|
|
|
3ea658 |
For working with newly introduced dmi sysfs the dmifs library
|
|
|
3ea658 |
was used. It's needed by the systems that cannot use /dev/mem to
|
|
|
3ea658 |
access hardware addresses and as result cannot read dmi table.
|
|
|
3ea658 |
So another, more correct approach, can be used, it's to read
|
|
|
3ea658 |
information from dmi sysfs.
|
|
|
3ea658 |
|
|
|
3ea658 |
Currently we can use libdmifs library for that.
