+ [KNL,SMP] debug: override scheduler migration costs
+ Format: <level-1-usecs>,<level-2-usecs>,...
+ This debugging option can be used to override the
+ default scheduler migration cost matrix. The numbers
+ are indexed by 'CPU domain distance'.
+ E.g. migration_cost=1000,2000,3000 on an SMT NUMA
+ box will set up an intra-core migration cost of
+ 1 msec, an inter-core migration cost of 2 msecs,
+ and an inter-node migration cost of 3 msecs.
+
+ WARNING: using the wrong values here can break
+ scheduler performance, so it's only for scheduler
+ development purposes, not production environments.
+
+ migration_debug=
+ [KNL,SMP] migration cost auto-detect verbosity
+ Format=<0|1|2>
+ If a system's migration matrix reported at bootup
+ seems erroneous then this option can be used to
+ increase verbosity of the detection process.
+ We default to 0 (no extra messages), 1 will print
+ some more information, and 2 will be really
+ verbose (probably only useful if you also have a
+ serial console attached to the system).
+
+ migration_factor=
+ [KNL,SMP] multiply/divide migration costs by a factor
+ Format=<percent>
+ This debug option can be used to proportionally
+ increase or decrease the auto-detected migration
+ costs for all entries of the migration matrix.
+ E.g. migration_factor=150 will increase migration
+ costs by 50%. (and thus the scheduler will be less
+ eager migrating cache-hot tasks)
+ migration_factor=80 will decrease migration costs
+ by 20%. (thus the scheduler will be more eager to
+ migrate tasks)
+
+ WARNING: using the wrong values here can break
+ scheduler performance, so it's only for scheduler
+ development purposes, not production environments.

+Firmware support for CPU hotplug under Linux/x86-64
+---------------------------------------------------
+
+Linux/x86-64 supports CPU hotplug now. For various reasons Linux wants to
+know in advance boot time the maximum number of CPUs that could be plugged
+into the system. ACPI 3.0 currently has no official way to supply
+this information from the firmware to the operating system.
+
+In ACPI each CPU needs an LAPIC object in the MADT table (5.2.11.5 in the
+ACPI 3.0 specification). ACPI already has the concept of disabled LAPIC
+objects by setting the Enabled bit in the LAPIC object to zero.
+
+For CPU hotplug Linux/x86-64 expects now that any possible future hotpluggable
+CPU is already available in the MADT. If the CPU is not available yet
+it should have its LAPIC Enabled bit set to 0. Linux will use the number
+of disabled LAPICs to compute the maximum number of future CPUs.
+
+In the worst case the user can overwrite this choice using a command line
+option (additional_cpus=...), but it is recommended to supply the correct
+number (or a reasonable approximation of it, with erring towards more not less)
+in the MADT to avoid manual configuration.

- This option enables support for the MPC 834x SYS evaluation board.
-
- Be aware that PCI buses can only function when SYS board is plugged
- into the PIB (Platform IO Board) board from Freescale which provide
- 3 PCI slots. The PIBs PCI initialization is the bootloader's

Support the IOMMU. Needed to run systems with more than 3GB of memory
properly with 32-bit PCI devices that do not support DAC (Double Address
Cycle). The IOMMU can be turned off at runtime with the iommu=off parameter.
Normally the kernel will take the right choice by itself.
