| Title: Test to verify the behavior of CONFIG_ZERO_LATENCY_IRQS at runtime (ARM Only) |
| |
| Description: |
| |
| This test verifies the behavior of CONFIG_ZERO_LATENCY_IRQS at runtime. |
| In particular, it tests that IRQs configured with the IRQ_ZERO_LATENCY |
| flag are assigned the highest priority in the system (and, therefore, |
| cannot be masked-out by irq_lock()). |
| Only for ARMv7-M and ARMv8-M Mainline targets. |

| Building and Running Project: |
| |
| This project outputs to the console. It can be built and executed on QEMU as |
| follows: |
| |
| ninja/make run |
| |
| --------------------------------------------------------------------------- |
| |
| Troubleshooting: |
| |
| Problems caused by out-dated project information can be addressed by |
| issuing one of the following commands then rebuilding the project: |
| |
| ninja/make clean # discard results of previous builds |
| # but keep existing configuration info |
| or |
| ninja/make pristine # discard results of previous builds |
| # and restore pre-defined configuration info |
| |
