crash_kexec_post_notifiers
- Run kdump after running panic-notifiers and dumping
- kmsg. This only for the users who doubt kdump always
- succeeds in any situation.
- Note that this also increases risks of kdump failure,
- because some panic notifiers can make the crashed
- kernel more unstable.
+ Only jump to kdump kernel after running the panic
+ notifiers and dumping kmsg. This option increases
+ the risks of a kdump failure, since some panic
+ notifiers can make the crashed kernel more unstable.
+ In configurations where kdump may not be reliable,
+ running the panic notifiers could allow collecting
+ more data on dmesg, like stack traces from other CPUS
+ or extra data dumped by panic_print. Note that some
+ configurations enable this option unconditionally,
+ like Hyper-V, PowerPC (fadump) and AMD SEV-SNP.
crashkernel=size[KMG][@offset[KMG]]
[KNL,EARLY] Using kexec, Linux can switch to a 'crash kernel'
failslab=

fail_make_request=[KNL]
General fault injection mechanism.

nomio [S390] Do not use MIO instructions.
norid [S390] ignore the RID field and force use of
one PCI domain per PCI function
+ notph [PCIE] If the PCIE_TPH kernel config parameter
+ is enabled, this kernel boot option can be used
+ to disable PCIe TLP Processing Hints support
+ system-wide.
pcie_aspm= [PCIE] Forcibly enable or ignore PCIe Active State Power
Management.
Set time (jiffies) between CPU-hotplug operations,
or zero to disable CPU-hotplug testing.
- rcutorture.read_exit= [KNL]
- Set the number of read-then-exit kthreads used
- to test the interaction of RCU updaters and
- task-exit processing.
-
rcutorture.read_exit_burst= [KNL]
The number of times in a given read-then-exit
episode that a set of read-then-exit kthreads
The delay, in seconds, between successive
read-then-exit testing episodes.
+ rcutorture.reader_flavor= [KNL]
+ A bit mask indicating which readers to use.
+ If there is more than one bit set, the readers
+ are entered from low-order bit up, and are
+ exited in the opposite order. For SRCU, the
+ 0x1 bit is normal readers, 0x2 NMI-safe readers,
+ and 0x4 light-weight readers.
+
rcutorture.shuffle_interval= [KNL]
Set task-shuffle interval (s). Shuffling tasks
allows some CPUs to go into dyntick-idle mode
non-zero "wait" parameter. See weight_single
and weight_many.
+ sdw_mclk_divider=[SDW]
+ Specify the MCLK divider for Intel SoundWire buses in
+ case the BIOS does not provide the clock rate properly.
+
skew_tick= [KNL,EARLY] Offset the periodic timer tick per cpu to mitigate
xtime_lock contention on larger systems, and/or RCU lock
contention on all systems with CONFIG_MAXSMP set.
For more information see Documentation/mm/slub.rst.
(slub_nomerge legacy name also accepted for now)
+ slab_strict_numa [MM]
+ Support memory policies on a per object level
+ in the slab allocator. The default is for memory
+ policies to be applied at the folio level when
+ a new folio is needed or a partial folio is
+ retrieved from the lists. Increases overhead
+ in the slab fastpaths but gains more accurate
+ NUMA kernel object placement which helps with slow
+ interconnects in NUMA systems.

- Format: <size>,<size>[KMG]:<state>;<size>-<size>[KMG]:<state>
+ Format: <size>[KMG],<size>[KMG]:<state>;<size>[KMG]-<size>[KMG]:<state>
state is one of "always", "madvise", "never" or "inherit".
Control the default behavior of the system with respect
to anonymous transparent hugepages.
Force threading of all interrupt handlers except those
marked explicitly IRQF_NO_THREAD.
+ thp_shmem= [KNL]
+ Format: <size>[KMG],<size>[KMG]:<policy>;<size>[KMG]-<size>[KMG]:<policy>
+ Control the default policy of each hugepage size for the
+ internal shmem mount. <policy> is one of policies available
+ for the shmem mount ("always", "inherit", "never", "within_size",
+ and "advise").

Specify if the kernel should make use of the cpu
torture.verbose_sleep_duration= [KNL]
Duration of each verbose-printk() sleep in jiffies.
+ tpm.disable_pcr_integrity= [HW,TPM]
+ Do not protect PCR registers from unintended physical
+ access, or interposers in the bus by the means of
+ having an integrity protected session wrapped around
+ TPM2_PCR_Extend command. Consider this in a situation
+ where TPM is heavily utilized by IMA, thus protection
+ causing a major performance hit, and the space where
+ machines are deployed is by other means guarded.
+
tpm_suspend_pcr=[HW,TPM]
Format: integer pcr id
Specify that at suspend time, the tpm driver
reserve_mem=12M:4096:trace trace_instance=boot_map^traceoff^traceprintk@trace,sched,irq
+ Note, saving the trace buffer across reboots does require that the system
+ is set up to not wipe memory. For instance, CONFIG_RESET_ATTACK_MITIGATION
+ can force a memory reset on boot which will clear any trace that was stored.
+ This is just one of many ways that can clear memory. Make sure your system
+ keeps the content of memory across reboots before relying on this option.
+

+ transparent_hugepage_shmem= [KNL]
+ Format: [always|within_size|advise|never|deny|force]
