Subject: [PATCH v2] genirq: Add the entropy pool function to the PPI interrupt handler
Date: Tue, 16 Jun 2026 16:17:30 +0800	[thread overview]
Message-ID: <20260616081730.4035-1-enlin.mu@linux.dev> (raw)

Accelerate the entropy pool initialization process.
The function handle_irq_event_percpu adds entropy pool
initialization, but this logic is missing in the PPI interrupt handler.
I think this was simply an accidental omission.
