The power7_set_irq() and power9_set_irq() functions set this but it is
|
|
|
902636 |
never used actually. Modern Book3s compatible CPUs are only supported
|
|
|
902636 |
by the pnv and spapr machines. They have an interrupt controller, XICS
|
|
|
902636 |
for POWER7/8 and XIVE for POWER9, whose models don't require to track
|
|
|
902636 |
IRQ input states at the CPU level.
|
|
|
902636 |
|
|
|
902636 |
Drop these lines to avoid confusion.
