From 2215e297b9af4a42fefd1c014f7a3048995cea97 Mon Sep 17 00:00:00 2001 From: Doug Brown Date: Fri, 13 Sep 2024 15:31:47 +0100 Subject: [PATCH] hw/net/can/xlnx-versal-canfd: Fix interrupt level The interrupt level should be 0 or 1. The existing code was using the interrupt flags to determine the level. In the only machine currently supported (xlnx-versal-virt), the GICv3 was masking off all bits except bit 0 when applying it, resulting in the IRQ never being delivered.
