+.Nm hpet
+.Nd High Precision Event Timer
+.Sh SYNOPSIS
+.Cd "hpet* at acpi?"
+.Cd "hpet* at amdpcib?"
+.Cd "hpet* at ichlpcib?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports High Precision Event Timers
+.Pq Tn HPETs .
+The
+.Tn HPET
+architecture defines one main 64-bit counter and several
+additional timers with variable width.
+The minimum clock frequency of the main timecounter is 10 MHz,
+but much higher rates are common.
+The additional 32 or 64 -bit parts are typically accessible via
+.Tn MMIO
+that is set by the system
+.Tn BIOS
+through
+.Tn ACPI .
+.Pp
+As a
+.Tn HPET
+can provide higher interrupt rates than a
+.Tn RTC
+or
+.Xr attimer 4 ,
+multimedia is one typical application context.
+The interrupt logic is configurable through
+.Tn I/O
+.Tn APIC ,
+but a legacy mode is provided for older systems.
