- [KNL] verbose self-tests

+ [KNL] verbose locking self-tests
+ Format: <int>
Print debugging info while doing the locking API
self-tests.
- We default to 0 (no extra messages), setting it to
- 1 will print _a lot_ more information - normally
- only useful to kernel developers.

For example, to override I2C bus2:
omap_mux=i2c2_scl.i2c2_scl=0x100,i2c2_sda.i2c2_sda=0x100
- oprofile.timer= [HW]
- Use timer interrupt instead of performance counters
-
- oprofile.cpu_type= Force an oprofile cpu type
- This might be useful if you have an older oprofile
- userland or if you want common events.
- Format: { arch_perfmon }
- arch_perfmon: [X86] Force use of architectural
- perfmon on Intel CPUs instead of the
- CPU specific event set.
- timer: [X86] Force use of architectural NMI
- timer mode (see also oprofile.timer
- for generic hr timer mode)

oops=panic Always panic on oopses. Default is to just kill the

rcutree.rcu_fanout_exact= [KNL]
Disable autobalancing of the rcu_node combining

Set wakeup interval for idle CPUs that have
RCU callbacks (RCU_FAST_NO_HZ=y).
- rcutree.rcu_idle_lazy_gp_delay= [KNL]
- Set wakeup interval for idle CPUs that have

+ rcutorture.nocbs_toggle= [KNL]
+ Set the delay in milliseconds between successive

rcutorture.nreaders= [KNL]
Set number of RCU readers. The value -1 selects
N-1, where N is the number of CPUs. A value

+ But note that CONFIG_PREEMPT_RT=y kernels enables

rcupdate.rcu_task_ipi_delay= [KNL]
Set time in jiffies during which RCU tasks will
avoid sending IPIs, starting with the beginning
refscale.verbose= [KNL]
Enable additional printk() statements.
