No effect on config_tiny_RCU kernels.
Y always_sync (issue a synchronize_cache even if the device claims no cache) Example: user_debug KNL, ARM Format: int See arch/arm/bug help text.Nodomains PCI Disable support for multiple PCI root domains (aka PCI segments, in acpi-speak).Ima_policy IMA The builtin measurement policy to load during IMA setup.Evm' to be updated regardless of current integrity status.Disable the driving of swap pages to the hypervisor.Shuffling tasks allows some CPUs to go into dyntick-idle mode during the locktorture test.Tuner bulk_removeoff PPC This parameter disables the use of the pSeries firmware feature for flushing multiple hpte entries at a time.Enabling slub_debug can create guard zones around objects freeable checkbook register software and may poison objects when not in use.Format: sppps2eppecpecpepp pause_on_oops Halt all CPUs after the first oops has been printed for the specified number of seconds.Nobats PPC Do not use BATs for mapping kernel lowmem on "Classic" PPC cores.Sti parisc, HW Format: num Set the STI (builtin display/keyboard on the HP-parisc machines) console (graphic card) which should be used as the initial boot-console.
Memtest fills the memory with this pattern, validates memory contents and reserves bad memory regions that are detected.Nobios X86-32 disallow use of PCI bios, only direct hardware access methods are allowed.Set this to zero to disable callback-flood testing.Information is printed at kern_debug so loglevel8 may also need to be specified.Up to 8 (IP_VS_APP_MAX_ports) ports may be specified.This is supported for legacy.Nr_cpus SMP Maximum number of processors kenwood dishwasher kdw12st3a user manual that an SMP kernel could support.Cdns, addr,options Start an early, polled-mode console on a Cadence (xuartps) serial port at the specified address.Smh Use ARM semihosting calls for early console.This tests RCU's ability to transition abruptly to and from idle.To turn off having tracepoints sent to printk, echo 0 Note, echoing 1 into this file without the tracepoint_printk kernel cmdline option has no effect.Note that such command can only affect the.
