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
is a lot of faster
+ off - do not initialize any AMD IOMMU found in
+ the system
amijoy.map= [HW,JOY] Amiga joystick support
Map of devices attached to JOY0DAT and JOY1DAT
as early as possible in order to facilitate early
boot debugging.
- ftrace_dump_on_oops
+ ftrace_dump_on_oops[=orig_cpu]
[FTRACE] will dump the trace buffers on oops.
+ If no parameter is passed, ftrace will dump
+ buffers of all CPUs, but if you pass orig_cpu, it will
+ dump only the buffer of the CPU that triggered the
+ oops.
ftrace_filter=[function-list]
[FTRACE] Limit the functions traced by the function
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
tp720= [HW,PS2]
+ tpm_suspend_pcr=[HW,TPM]
+ Format: integer pcr id
+ Specify that at suspend time, the tpm driver
+ should extend the specified pcr with zeros,
+ as a workaround for some chips which fail to
+ flush the last written pcr on TPM_SaveState.
+ This will guarantee that all the other pcrs
+ are saved.
+
trace_buf_size=nn[KMG]
[FTRACE] will set tracing buffer size.
default x2apic cluster mode on platforms
supporting x2apic.
+ x86_mrst_timer= [X86-32,APBT]
+ Choose timer option for x86 Moorestown MID platform.
+ Two valid options are apbt timer only and lapic timer
+ plus one apbt timer for broadcast timer.
+ x86_mrst_timer=apbt_only | lapic_and_apbt

xd= [HW,XT] Original XT pre-IDE (RLL encoded) disks.
