What: /sys/devices/.../removable
Date: May 2021
Contact: Rajat Jain <[email protected]>
Description:
Information about whether a given device can be removed from the
platform by the user. This is determined by its subsystem in a
bus / platform-specific way. This attribute is only present for
devices that can support determining such information:
=========== ===================================================
"removable" device can be removed from the platform by the user
"fixed" device is fixed to the platform / cannot be removed
by the user.
"unknown" The information is unavailable / cannot be deduced.
=========== ===================================================
Currently this is only supported by USB (which infers the
information from a combination of hub descriptor bits and
platform-specific data such as ACPI) and PCI (which gets this
from ACPI / device tree).
