2.11. The PC Card Daemon
The
pcscd daemon is used to manage connections to PC and SC smart card readers. Although pcscd is usually a low priority task, it can often use more CPU than any other daemon. This additional background noise can lead to higher pre-emption costs to real-time tasks and other undesirable impacts on determinism.
Procedure 2.10. Disabling the pcscd Daemon
- Check the status of the
pcscddaemon.~]# systemctl status pcscd pcscd.service - PC/SC Smart Card Daemon Loaded: loaded (/usr/lib/systemd/system/pcscd.service; static) Active: active (running) … - If the
pcscddaemon is running, stop it.~]# systemctl stop pcscd - Ensure that
pcscddoes not restart on boot.~]# systemctl disable pcscd
