From 698b48532539484b012fb7c4176b959d32a17d00 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Stefan=20S=C3=B8rensen?= Date: Thu, 6 Mar 2014 16:27:15 +0100 Subject: [PATCH] ARM: OMAP2+: INTC: Acknowledge stuck active interrupts MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When an interrupt has become active on the INTC it will stay active until it is acked, even if masked or de-asserted. The INTC_PENDING_IRQn registers are however updated and since these are used by omap_intc_handle_irq to determine which interrupt to handle, it will never see the active interrupt. This will result in a storm of useless interrupts that is only stopped when another higher priority interrupt is asserted. Fix by sending the INTC an acknowledge if we find no interrupts to handle.
