https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207086 --- Comment #9 from commit-hook@freebsd.org --- A commit references this bug: Author: avg Date: Tue May 26 05:54:00 UTC 2020 New revision: 361495 URL: https://svnweb.freebsd.org/changeset/base/361495 Log: MFC r360657: acpi_video: support systems without non-essential methods Only _BCL and _BCM methods seem to be essential to the driver's operation. If _BQC is missing then we can assume that the current brightness is whatever we set by the last _BCM invocation. If _DCS or _DGS is missing then we can make assumptions as well. The change is based on a patch suggested by Anthony Jenkins <Scoobi_doo@yahoo.com> in PR 207086.
