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).
