Hardware Abstraction Layer
Please note
HAL is in the process of being deprecated by upstream, replaced by udev, udisks, upower etc. For information about the progress within Debian, see HALRemoval.
HAL provides an abstract view on hardware. This abstraction layer is simply an interface that makes it possible to add support for new devices and new ways of connecting devices to the computer, without modifying every application that uses the device.
- It maintains a list of devices that currently exist, and can provide information about those upon request.
It provides an infrastructure to configure [any] device. (It was used by Xorg too).
Read HAL specifications: Introduction for more information.
In Debian
HAL (hal, hal-info) was only installed on Debian Desktop/Laptops by default. (It is not a Priority=standard package).
Sample programs:
lshal(1) -- list HAL devices.
hal-find-by-property(1) -- find device objects by property matching.
hal-find-by-capability(1) -- find device objects by capability matching.
gnome-device-manager, which is a Gnome tool to view the devices on the local machine:
