https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216552 Bug ID: 216552 Summary: [patch] acpi_asus_als: driver for the ambient light sensor on ASUS laptops Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Keywords: patch Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: henry.hu.sh@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Keywords: patch Created attachment 179378 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=179378&action=edit patch for the driver This driver calls the ACPI methods to obtain the ambient light sensor value on recent ASUS laptops. It is inspired by the similar driver for Linux at https://github.com/victorenator/als. Only the specifications in the README file is referenced to. It provides sysctl node hw.acpi.asus_als.light which contains the current light sensor value. The unit seems to be 0.01 lux (compared to a mobile phone). This patch creates a new module under /sys/modules/acpi called acpi_asus_als. After loading the module, it attaches to ACPI device with hardware ID ACPI0008 and provides the sysctl node mentioned above. This driver is tested under 12-CURRENT on an ASUS UX51VZ laptop. -- You are receiving this mail because: You are the assignee for the bug.
