IRQ number to use for testing purposes. This should be an
available/unused IRQ on the target platform.
Platform-specific defaults:
- QEMU Cortex-M3: 42 (available test IRQ)
- GIC platforms: 14 (available test SGI - Software Generated Interrupt)
- DA1469X series: 22 (available test IRQ)
- STM32C0X series: 18 (available test IRQ)
- Other platforms: 0 (magic config value to select the last IRQ: NUM_IRQS - 1)
config TEST_IRQ_PRIO
int "Test IRQ priority"
default 160 if GIC
default 1
help
Platform-specific defaults:
- GIC platforms: IRQ_DEFAULT_PRIORITY (system default)
- Other platforms: 1 (high priority for testing)
