From: Peter Maydell Date: Thu, 20 Feb 2014 10:35:48 +0000 Subject: [PATCH] hw/intc/arm_gic: Fix NVIC assertion failure Commit 40d225009ef accidentally changed the behaviour of gic_acknowledge_irq() for the NVIC. The NVIC doesn't have SGIs, so this meant we hit an assertion: gic_acknowledge_irq: Assertion `s->sgi_pending[irq][cpu] != 0' failed. Return NVIC acknowledge-irq to its previous behaviour, like 11MPCore.
