acpihed — ACPI Hardware Error Device

SYNOPSIS

acpihed* at acpi?

DESCRIPTION

Certain hardware error sources that can be queried by apei(4) notify an ACPI node with PNP ID ‘PNP0C33’ when an error occurs. The acpihed driver listens for these notifications and passes them on to apei(4) so it can report the error.
