interrupt.12This happens for an interrupt at First Clock, while a reset can happen any time in the instruction cycle. A trap goes to theINT1microcode routine described earlier, while an NMI interrupt goes toINT2microcode routine. The microcode for theINTRinterrupt will be discussed in the ...

During the interrupt acknowledge cycle, the G80 automatically disables its interrupt mechanism. Thus, at some point in the interrupt service routine, the programmer must include an Enable Interrupt instruction, ei, to re-enable the interrupt facility. This is often done just before the reti instruc...
In the interrupt acknowledge cycle, the processor asserts the INTA (interrupt acknowledge) line to the PIC, expecting an interrupt vector number. 5. The PIC drives the interrupt vector number associated with device A to the system bus. 6. The PIC then deasserts the INT line (so that a new...
If the driver you're testing acquires and releases the interrupt at each open and close cycle, you may find /proc/stat more useful than /proc/interrupts. Another difference between the two files is that interrupts is not architecture dependent, whereas stat is: the number of fields depends ...

Assuming X CPU cycles is spent to scan one double word under lock mode and assuming N is the number of VPs in a VM, the total CPU cycle spent scanning all PIRR for N VPs is 4*X*N (i.e., four double words per PIRR). System 100 of FIG. 1A eliminates the four-double reads for...
