/*

|
* GIC priorities from the view of the PMR/RPR.
|
|
*
|
|
* These values are chosen to be valid in either the absolute priority space or
|
|
* the NS view of the priority space. The value programmed into the distributor
|
|
* and ITS will be chosen at boot time such that these values appear in the
|
|
* PMR/RPR.
|
|
*
|
|
* GICV3_PRIO_UNMASKED is the PMR view of the priority to use to permit both
|
|
* IRQs and pseudo-NMIs.
|
|
*
|
|
* GICV3_PRIO_IRQ is the PMR view of the priority of regular interrupts. This
|
|
* can be written to the PMR to mask regular IRQs.
|
|
*
|
|
* GICV3_PRIO_NMI is the PMR view of the priority of pseudo-NMIs. This can be
|
|
* written to the PMR to mask pseudo-NMIs.
|
|
*
|
|
* On arm64 some code sections either automatically switch back to PSR.I or
|
|
* explicitly require to not use priority masking. If bit GICV3_PRIO_PSR_I_SET
|
|
* is included in the priority mask, it indicates that PSR.I should be set and
|
|
* interrupt disabling temporarily does not rely on IRQ priorities.
