fpsd

- Fp-scrubber daemon

Synopsis

/usr/lib/fps/fpsd

Description

fpsd is a user-level daemon that periodically runs non-intrusive tests to validate proper functioning of FPU (Floating Point Unit) hardware in the system. A fault management action is initiated by means of fmd(1M), in case an error is detected by the test.

Exit Status

The following exit values are returned:

0

Successful completion.

non-zero

An error occurred.

Attributes

Notes

The fpsd service is managed by the service management facility, smf(5), under the service identifier:

svc:/system/fpsd:default

You can use svccfg(1M) to change the default fpsd behavior:

Property Name            Type     Description
-------------            ----     -----------
config/exclude_cpus      astring  comma delimited list of
                                   CPU IDs to be excluded
                                   from proactive testing.

Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.

Disabling the service can increase system's vulnerability to silent data corruption, if a fault were to develop in an FPU within the system.
