[RFC PATCH v2 22/29] target/ppc: remove unused interrupts from p7_deliver_interrupt |
Date: |
Tue, 27 Sep 2022 17:15:37 -0300 |
Remove the following unused interrupts from the POWER7 interrupt
processing method:
- PPC_INTERRUPT_RESET: only raised for 6xx, 7xx, 970, and POWER5p;
- Hypervisor Virtualization: introduced in Power ISA v3.0;
- Hypervisor Doorbell and Event-Based Branch: introduced in
Power ISA v2.07;
- Critical Input, Watchdog Timer, and Fixed Interval Timer: only defined
for embedded CPUs;
- Doorbell and Critical Doorbell Interrupt: processor does not implement
the "Embedded.Processor Control" category;
- Programmable Interval Timer: 40x-only;
- PPC_INTERRUPT_THERM: only raised for 970 and POWER5p;
