Image Linux 2.6 oops parisc.jpg thumb right Linuxkernel oops on PA RISC with a dead ASCII cow. An oops is a deviation from correct behavior of the Linuxkernel which produces a certain error log. The better known kernel panic condition results from many kinds of oops, but others may allow continued operation with compromised Reliability engineering reliability . The term does not stand for anything, other than that it is a simple mistake. When the kernel detects a problem, it prints an oops message and kill Unix kill s any offending process computing process .

In mathematics , the word kernel has several meanings. Kernel may mean a subset associated with a Map mathematics mapping The kernel of a mapping is the set of elements that map to the Additive identity zero element such as zero or Null vector zero vector , as in kernel linear operator kernel of a linear operator and kernel matrix kernel of a matrix . In this context, kernel is often called nullspace . More generally, the kernel algebra kernel in algebra is the set of elements that map to the neutral ..., and, in particular, maps neutral element to neutral element. The kernel is then the set of all elements that the mapping cannot distinguish from the neutral element. The Kernel category theory kernel in category theory is a generalization of this concept to morphism s rather than mappings between sets. In set theory, the Kernel set theory kernel of a function is the set of all pairs of elements ... of the kernel concept above to the case when there is no neutral element. In set theory, the equalizer mathematics difference kernel or binary equalizer is the set of all elements where the values of two functions coincide. Kernel may also mean a function of two variables, which is used to define a mapping In integral calculus , the kernel also called integral kernel or kernel function is a function ... for the right hand side f can be written as Tf above, the kernel becomes the Green s function . The heat kernel is the Green s function of the heat equation. In the case when the integral kernel depends only on the difference between its arguments, it becomes a convolution kernel , as in math T f x int X phi x x f x , dx . math In statistics , a kernel statistics kernel is a weighting function used in kernel density estimation to estimate the probability density function of a random variable . In probability theory and statistics , a stochastic kernel is the transition function of a stochastic ... as the kernel of the integral operator that advances the probability density function .

notability date February 2009 unreferenced date February 2009 Kernel preemption is a method used mainly in monolithic kernel monolithic and hybrid kernel hybrid kernel computing kernel s where all or most device drivers are run in kernel space , whereby the Scheduling computing scheduler is permitted to forcibly perform a context switch i.e. preemptively schedule on behalf of a runnable and higher priority process on a driver or other part of the kernel during its execution, rather than Computer multitasking Cooperative multitasking.2Ftime sharing co operatively wait for the driver or kernel function such as a system call to complete its execution and return control of the processor to the scheduler. There are two main benefits to this method in monolithic and hybrid kernels, and answer one of the main criticisms of monolithic kernels from microkernel advocates, which is that A device driver can enter an infinite loop or other unrecoverable state, crashing the whole system Some drivers and system calls on monolithic kernels are slow to execute, and can t return control of the processor to the scheduler or other program until they complete execution.
