/SPL/ [abbrev, from Set Priority Level] The way traditional Unix kernels
|
|
|
|
|
implement mutual exclusion by running code at high interrupt levels. Used in
|
|
|
|
|
jargon to describe the act of tuning in or tuning out ordinary
|
|
|
|
|
communication. Classically, spl levels run from 1 to 7; Fred's at spl 6
|
|
|
|
|
today would mean that he is very hard to interrupt. Wait till I finish this;
|
|
|
|
|
I'll spl down then. See also interrupts locked out.
