PMU fast interrupt mode on Ultrascale+

I understand the Microblaze Architecture supports a fast interrupt mode.

On the Ultrascale+ there is a IRQ_MODE register in the PMU_GLOBAL module to enable fast interrupt mode for dedicated interrupt sources.

However, the Technical Reference Manual says, a PMU interrupt is always served by the PMU ROM code first.

Is it possible to use fast interrupts for the PMU?

And if so how do you pass the address of the interrupt vector to the interrupt controller?

 

Regards

Manfred
