[edit] Statistical data
statistical data seems to be missing? -- paniq
- Do you mean typical context switch latency, or something else? Patrik Hägglund 17:37, 21 June 2006 (UTC)
[edit] ELF?
I removed:
- The ELF Interface is one such architecture. A distinct advantage to Human users of unix-like systems is an override cabability inherent in the interfaces: Stdin, Stdout and Stderr, which are nearly always accesable to both root users and normal users.
What does ELF have to do with context switching? The discussion of stdin / stdout / stderr that follows doesn't make any sense, either. Neilc 01:10, 24 July 2005 (UTC)
[edit] Interrupt handling
"Clearly, there is a necessity to switch contexts when issuing interrupts: so that the interrupt handler can be executed, the state of the currently running process must be suspended."
This needs an explanation. The article gives the impression that all interrupts results in a context swith. This is not consistent with my understanding of interrupts. Rather it should depend on the type of the interrupt and the interrupt handling framework (the OS). Do you say that a context switch occurs when you use a DOS interrupt call? If that is the case, what's the difference between such a call and a normal function call?

[edit] Operator context switching?
What about the concept of user context switching? As in "the PSP is crap because it forces the programmer to context switch too often"? Does this usage deserve a mention? Sam Wilson 00:48, 24 July 2006 (UTC)
[edit] Task Gate
Is a task gate the same thing as a Barrier_(computer_science)? Mateja 01:11, 13 November 2006 (UTC)
[edit] Max switchframes and contexts
Is there a limit to number of switchframes and contexts maintained by a CPU? Are there examples for Xeon, Opteron, Itanium, Pentium?
[edit] Expansion on types of context switches
What are the differences between register, task, thread and process context switches? what are the relative time penalty? when are they used?
[edit] Section "Within psychology"
I removed the stub-section "Within psychology" containing the text
- Task switching a method used to assess executive control of cognition
Is there anything on Wikipedia about context switching in terms of psychology? If there is, I can't find it; if the concept is actually used in psychology, there should be a link to a relevant page. -Shai-kun 04:27, 5 June 2007 (UTC)
