- Format: <reboot_mode>[,<reboot_mode2>[,...]]
- See arch/*/kernel/reboot.c or arch/*/kernel/process.c
+ reboot= [KNL]
+ Format (x86 or x86_64):

+ [[,]s[mp]#### \
+ [[,]b[ios] | a[cpi] | k[bd] | t[riple] | e[fi] | p[ci]] \
+ [[,]f[orce]
+ Where reboot_mode is one of warm (soft) or cold (hard) or gpio,
+ reboot_type is one of bios, acpi, kbd, triple, efi, or pci,
+ reboot_force is either force or not specified,
+ reboot_cpu is s[mp]#### with #### being the processor

relax_domain_level=
[KNL, SMP] Set scheduler's default relax_domain_level.
Force threading of all interrupt handlers except those
marked explicitly IRQF_NO_THREAD.
+ tmem [KNL,XEN]
+ Enable the Transcendent memory driver if built-in.
+
+ tmem.cleancache=0|1 [KNL, XEN]
+ Default is on (1). Disable the usage of the cleancache
+ API to send anonymous pages to the hypervisor.
+
+ tmem.frontswap=0|1 [KNL, XEN]
+ Default is on (1). Disable the usage of the frontswap
+ API to send swap pages to the hypervisor. If disabled
+ the selfballooning and selfshrinking are force disabled.
+
+ tmem.selfballooning=0|1 [KNL, XEN]
+ Default is on (1). Disable the driving of swap pages
+ to the hypervisor.
+
+ tmem.selfshrinking=0|1 [KNL, XEN]
+ Default is on (1). Partial swapoff that immediately
+ transfers pages from Xen hypervisor back to the
+ kernel based on different criteria.
+
topology= [S390]
Format: {off | on}
Specify if the kernel should make use of the cpu
See also Documentation/trace/ftrace.txt "trace options"
section.
+ traceoff_on_warning
+ [FTRACE] enable this option to disable tracing when a
+ warning is hit. This turns off "tracing_on". Tracing can
+ be enabled again by echoing '1' into the "tracing_on"
+ file located in /sys/kernel/debug/tracing/
+
+ This option is useful, as it disables the trace before
+ the WARNING dump is called, which prevents the trace to
+ be filled with content caused by the warning output.
+
+ This option can also be set at run time via the sysctl
+ option: kernel/traceoff_on_warning

video= [FB] Frame buffer configuration
See Documentation/fb/modedb.txt.
+ video.brightness_switch_enabled= [0,1]
+ If set to 1, on receiving an ACPI notify event
+ generated by hotkey, video driver will adjust brightness
+ level and then send out the event to user space through
+ the allocated input device; If set to 0, video driver
+ will only send out the event without touching backlight
+ brightness level.

[VMMIO] Memory mapped virtio (platform) device.
that this also can be controlled per-workqueue for
workqueues visible under /sys/bus/workqueue/.
+ workqueue.power_efficient
+ Per-cpu workqueues are generally preferred because
+ they show better performance thanks to cache
+ locality; unfortunately, per-cpu workqueues tend to
+ be more power hungry than unbound workqueues.
+
+ Enabling this makes the per-cpu workqueues which
+ were observed to contribute significantly to power
+ consumption unbound, leading to measurably lower
+ power usage at the cost of small performance
+ overhead.
+
+ The default value of this parameter is determined by
+ the config option CONFIG_WQ_POWER_EFFICIENT_DEFAULT.
