ACPICPU(4) - Device Drivers Manual # ACPICPU(4) - Device Drivers Manual NAME # acpicpu - ACPI processor power and performance state SYNOPSIS # acpicpu* at acpi? DESCRIPTION # The acpicpu driver provides support for extracting processor power and performance levels from ACPI tables. This information is used to enter deeper CPU power states when idle, and can be used to throttle processor speed to reduce power usage and extend battery life through the hw. ...
ACPIMADT(4) - Device Drivers Manual # ACPIMADT(4) - Device Drivers Manual NAME # acpimadt - ACPI APIC configuration SYNOPSIS # acpimadt* at acpi? DESCRIPTION # The acpimadt driver configures system processors and I/O APICs based on information extracted from the ACPI APIC table. SEE ALSO # acpi(4), cpu(4), intro(4), ioapic(4) HISTORY # The acpimadt driver first appeared in OpenBSD 4.1. AUTHORS # The acpimadt driver was written by Mark Kettenis <kettenis@openbsd. ...
ASTRO(4) - Device Drivers Manual (hppa) # ASTRO(4) - Device Drivers Manual (hppa) NAME # astro - Astro Memory and I/O controller SYNOPSIS # astro* at mainbus? elroy* at astro? DESCRIPTION # The astro driver provides support for the Astro memory and I/O controller used on systems with PA-8500 and later 64-bit CPUs. It functions as a bridge from the Runway bus to up to 8 I/O ropes that connect to Elroy chips. ...
CPU(4) - Device Drivers Manual (amd64) # CPU(4) - Device Drivers Manual (amd64) NAME # cpu - Central Processing Unit SYNOPSIS # cpu0 at mainbus? cpu* at mainbus? DESCRIPTION # Several processor models have additional features that extend their base functionality, such as power and frequency control or thermal monitoring. FREQUENCY CONTROL # The sysctl(2) hw.cpuspeed returns the current operating frequency of the processor, though on some processors this value may be only an approximation. ...
CPU(4) - Device Drivers Manual (hppa) # CPU(4) - Device Drivers Manual (hppa) NAME # cpu - HP PA-RISC CPU SYNOPSIS # cpu* at mainbus0 irq 31 DESCRIPTION # The following table lists the PA-RISC CPU types and their characteristics, such as TLB, maximum cache sizes (where the ‘*’ character means on-chip) and HP 9000/700 machines they were used in (see also intro(4) for the reverse list). **CPU** **PA** **Clock** **Caches** **TLB** **BAT** **Models** MHz max KB max 7000 1. ...
