For irq_domain_associate() to work the virq descriptor has to be pre-allocated in advance. Otherwise the following happens: WARNING: CPU: 0 PID: 0 at .../kernel/irq/irqdomain.c:527 irq_domain_associate+0x298/0x2e8 error: virq128 is not allocated Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.19.78-... #1 ...
