+ acpi_no_auto_serialize [HW,ACPI]
+ Disable auto-serialization of AML methods
+ AML control methods that contain the opcodes to create
+ named objects will be marked as "Serialized" by the
+ auto-serialization feature.
+ This feature is enabled by default.
+ This option allows to turn off the feature.
+
acpi_no_auto_ssdt [HW,ACPI] Disable automatic loading of SSDT
+ acpica_no_return_repair [HW, ACPI]
+ Disable AML predefined validation mechanism
+ This mechanism can repair the evaluation result to make
+ the return objects more ACPI specification compliant.
+ This option is useful for developers to identify the
+ root cause of an AML interpreter issue when the issue
+ has something to do with the repair mechanism.
+
acpi_os_name= [HW,ACPI] Tell ACPI BIOS the name of the OS
Format: To spoof as Windows 98: ="Microsoft Windows"
acpi_sci= [HW,ACPI] ACPI System Control Interrupt trigger mode
Format: { level | edge | high | low }
- acpi_serialize [HW,ACPI] force serialization of AML methods
-
acpi_skip_timer_override [HW,ACPI]
Recognize and ignore IRQ0/pin2 Interrupt Override.
For broken nForce2 BIOS resulting in XT-PIC timer.
Enable debug messages at boot time. See
Documentation/dynamic-debug-howto.txt for details.
+ early_ioremap_debug [KNL]
+ Enable debug messages in early_ioremap support. This
+ is useful for tracking down temporary early mappings
+ which are not unmapped.
+
earlycon= [KNL] Output early console device and options.

parameter will force ia64_sal_cache_flush to call
ia64_pal_cache_flush instead of SAL_CACHE_FLUSH.
+ forcepae [X86-32]
+ Forcefully enable Physical Address Extension (PAE).
+ Many Pentium M systems disable PAE but may have a
+ functionally usable PAE implementation.
+ Warning: use of this parameter will taint the kernel
+ and may cause unknown problems.
+
ftrace=[tracer]
[FTRACE] will set and start the specified tracer
as early as possible in order to facilitate early
IOAPICs that may be present in the system.
nokaslr [X86]
- Disable kernel base offset ASLR (Address Space
- Layout Randomization) if built into the kernel.
+ Disable kernel and module base offset ASLR (Address
+ Space Layout Randomization) if built into the kernel.
noautogroup Disable scheduler automatic task group creation.
pcmv= [HW,PCMCIA] BadgePAD 4
+ pd_ignore_unused
+ [PM]
+ Keep all power-domains already enabled by bootloader on,
+ even if no driver has claimed them. This is useful
+ for debug and development, but should not be
+ needed on a platform with proper driver support.

vdso= [X86,SH]
- vdso=2: enable compat VDSO (default with COMPAT_VDSO)
- vdso=1: enable VDSO (default)
+ On X86_32, this is an alias for vdso32=. Otherwise:
+
+ vdso=1: enable VDSO (the default)
vdso=0: disable VDSO mapping
- vdso32= [X86]
- vdso32=2: enable compat VDSO (default with COMPAT_VDSO)
- vdso32=1: enable 32-bit VDSO (default)
- vdso32=0: disable 32-bit VDSO mapping
+ vdso32= [X86] Control the 32-bit vDSO
+ vdso32=1: enable 32-bit VDSO
+ vdso32=0 or vdso32=2: disable 32-bit VDSO
+
+ See the help text for CONFIG_COMPAT_VDSO for more
+ details. If CONFIG_COMPAT_VDSO is set, the default is
+ vdso32=0; otherwise, the default is vdso32=1.
+
+ For compatibility with older kernels, vdso32=2 is an
+ alias for vdso32=0.
+
+ Try vdso32=0 if you encounter an error that says:
