SDB:Kernel Parameters for ACPI/APIC

Şuraya atla: kullan, ara


Situation

You want to control the operation of ACPI (Advanced Configuration and Power Interface) and/or APIC (Advanced Programmable Interrupt Controller).

For more information on ACPI, refer to the articles:

SDB:General Information concerning ACPI Support

For further information on APIC, see:

Procedure

The operation of ACPI/APIC can be controlled by way of kernel parameters. These kernel parameters can be activated before the installation by passing them to the kernel at the boot prompt. If you do this before installing, the parameters will be automatically adopted by the boot loader configuration. It is also possible to enter the parameters in the boot loader configuration in YaST2. For more information about the boot loader configuration, refer to the article SDB:Inserting Boot Options Permanently

ACPI Kernel Parameters

acpi=off This parameter disables the whole ACPI system. This may prove very useful, for example, if your computer does not support ACPI or if you think the ACPI implementation might cause some problems.
acpi=force Activates the ACPI system even if your computer BIOS is prior to 2000. This parameter overwrites acpi=off and can also be used with current hardware if the ACPI support is not activated despite apm=off.
pci=noacpi
acpi=noirq
This parameter disables the PCI IRQ routing in the new ACPI system.
pci=acpi This parameter activates the PCI IRQ routing in the new ACPI system.
acpi_irq_balance ACPI is allowed to use PIC interrupts to minimize the common use of IRQs.
acpi_irq_nobalance ACPI is not allowed to use PIC interrupts.
acpi_irq_pci=irq-number List of IRQs that can be used by PCI.
acpi_irq_isa=irq-number List of IRQs that cannot be used by PCI.
acpi=oldboot Deactivates the ACPI system almost completely; only the components required for the boot process will be used.
acpi=ht Deactivates the ACPI system almost completely; only the components required for hyper threading will be used.

APIC Kernel Parameters

apic This parameter instructs the kernel to use the APIC system.
noapic This parameter instructs the kernel not to use the APIC system.
apic=verbose
apic=debug
Modify the quantity of information delivered by the APIC system on start.
lapic
Activates the local APIC system even if it is disabled in the BIOS.
nolapic
Disables the local APIC system even if it is activated in the BIOS.
