3.2.2 Processing Procedures for Service Calls from Handlers
When a service call is issued from a handler, task switching does not occur unlike in the case of a service call from a task.
However, task switching occurs when a return from a handler
7
is made.
The processing procedures for service calls from handlers are roughly classified into the following three types.
1. A service call from a handler that caused an interrupt during task execution
2. A service call from a handler that caused an interrupt during service call processing
3. A service call from a handler that caused an interrupt (multiplex interrupt) during handler exe-
cution
7
The service call can't be issued from non-kernel handler. Therefore, The handler described here does not include the non-kernel interrupt
handler.
