Using DISPLAY INTERRUPTS
When a processor is taken offline or when an interrupt handler (ISR) is
removed, the detailed statistics pertaining to that processor or interrupt
handler are, by default, removed from memory.
To retain per-processor interrupt handler statistics for offline processors or to
retain the total interrupt contribution from a previously loaded handler, change
the SET parameter Set Auto Clear Interrupt Statistics to OFF.
Examples
To display interrupts currently in use, enter DISPLAY INTERRUPTS with no
options. The display is similar to the following sample:
Total Interrupt Count For All Processors: 940208
Interrupt 0: OS Allocated Bus Interrupt 292828
Interrupt Handler: Timer 0 Interrupt Handler
Interrupt 1: OS Allocated Bus Interrupt 375
Interrupt Handler: Keyboard Interrupt Handler 375
Interrupt 5: OS Allocated Bus Interrupt 86229
Interrupt Handler: E100B Hardware ISR 94829
Interrupt 9: OS Allocated Bus Interrupt 30691
Interrupt Handler: NPA Environment 30691
Option Use to
(no option) Display interrupts currently in use.
n ... Display one or more interrupts by number.
ALL Display all interrupts.
PROC Display per-processor interrupt information.
ALLOC Display allocated interrupts.
REAL Display interrupts that occurred while the OS
was in real mode and that were then reflected
back to protected mode to be serviced.
