It was detected by test_sw_isr_irq_parent_table_idx in arch.interrupt: ASSERTION FAIL [table_idx < (186 - 0)] @ WEST_TOPDIR/zephyr/arch/common/multilevel_irq.c:91 table_idx(186) < IRQ_TABLE_SIZE(186) NUM_IRQS was previously set to the same value as MAX_IRQ_PER_AGGREGATOR and it didn't take into account the number of 1st level interrupts specified by 2ND_LVL_ISR_TBL_OFFSET. In the generated __sw_isr_table, Level 2 interrupts start at the offset specified by 2ND_LVL_ISR_TBL_OFFSET. For PolarFire SoC, upper interrupt sources for PLIC correspond to Bus Error Unit and Fabric Interface. They are currently not used by platforms in Zephyr, so the previous value of NUM_IRQS hasn't caused issues for regular applications. As it doesn't look like an explicit memory optimization, increase NUM_IRQS to allow kernel interrupt tests to pass. Note: 2ND_LVL_ISR_TBL_OFFSET=13 and NUM_IRQS=199 don't include additional 48 Local Interrupts supported by cores. In total, there are 64 bits in Machine Interrupt Pending Register (mip) which can be used to configure 1st level interrupts. As a further extension to the platform, values could be extended to 2ND_LVL_ISR_TBL_OFFSET=64 and NUM_IRQS=250. This commit increases NUM_IRQS by a minimal value required to pass kernel interrupt tests.

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways. The Zephyr kernel supports multiple architectures, including ARM (Cortex-A, Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, SPARC, MIPS, and a large number of `supported boards`_. .. below included in doc/introduction/introduction.rst Getting Started *************** Welcome to Zephyr!
