From 6941f74070ec0e639bb045107b969b7798947fae Mon Sep 17 00:00:00 2001 From: Greg V Date: Tue, 16 Mar 2021 01:06:01 +0300 Subject: [PATCH] quirks: implement DMI support on FreeBSD FreeBSD does not use Linux modaliases, so we have to generate these strings. Unfortunately for us, the data in kenv has the chassis type pre-parsed into a nice string, so we have to match these strings back into numbers. Only relevant types are included to avoid bloating the code.
