Subject: [kvm-unit-tests PATCH v7 03/13] arm/arm64: gic: Introduce setup_irq() helper
Date: Fri, 20 Mar 2020 10:24:18 +0100
Message-ID: <20200320092428.20880-4-eric.auger@redhat.com> (raw)
In-Reply-To: <20200320092428.20880-1-eric.auger@redhat.com>

ipi_enable() code would be reusable for other interrupts
than IPI. Let's rename it setup_irq() and pass an interrupt
handler pointer.

Signed-off-by: Eric Auger <eric.auger@redhat.com>

---

v4 -> v5:
- s/handler_t/irq_handler_t
- also add irq_handler_fn in lib/arm/asm/processor.h

v2 -> v3:
- do not export setup_irq anymore
