acpi= [HW,ACPI,X86]
Advanced Configuration and Power Interface
- Format: { force | off | ht | strict | noirq | rsdt }
+ Format: { force | off | strict | noirq | rsdt }
force -- enable ACPI if default was off
off -- disable ACPI if default was on
noirq -- do not use ACPI for IRQ routing
- ht -- run only enough ACPI to enable Hyper Threading
strict -- Be less tolerant of platforms that are not
strictly ACPI specification compliant.
rsdt -- prefer RSDT over (default) XSDT
acpi_display_output=video
See above.
- acpi_early_pdc_eval [HW,ACPI] Evaluate processor _PDC methods
- early. Needed on some platforms to properly
- initialize the EC.
-
acpi_irq_balance [HW,ACPI]
ACPI will balance active IRQs
default in APIC mode
amd_iommu= [HW,X86-84]
Pass parameters to the AMD IOMMU driver in the system.
Possible values are:
- isolate - enable device isolation (each device, as far
- as possible, will get its own protection
- domain) [default]
- share - put every device behind one IOMMU into the
- same protection domain
fullflush - enable flushing of IO/TLB entries when
they are unmapped. Otherwise they are
flushed before they will be reused, which
Default value is 0.
Value can be changed at runtime via /selinux/enforce.
+ erst_disable [ACPI]
+ Disable Error Record Serialization Table (ERST)
+ support.
+
ether= [HW,NET] Ethernet cards parameters
This option is obsoleted by the "netdev=" option, which
has equivalent usage. See its documentation for details.
hd= [EIDE] (E)IDE hard drive subsystem geometry
Format: <cyl>,<head>,<sect>
+ hest_disable [ACPI]
+ Disable Hardware Error Source Table (HEST) support;
+ corresponding firmware-first mode error processing
+ logic will be disabled.
+
highmem=nn[KMG] [KNL,BOOT] forces the highmem zone to have an exact
size of <nn>. This works even on boxes that have no
highmem otherwise. This also works to reduce highmem
libata.force= [LIBATA] Force configurations. The format is comma
separated list of "[ID:]VAL" where ID is
- PORT[:DEVICE]. PORT and DEVICE are decimal numbers
+ PORT[.DEVICE]. PORT and DEVICE are decimal numbers
matching port, link or device. Basically, it matches
the ATA ID string printed on console by libata. If
the whole ID part is omitted, the last PORT and DEVICE
