From c6f797d519aa1c4dd2736b3ffc1f7722f2d3c3c3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 8 Apr 2022 15:15:43 +0100 Subject: [PATCH] hw/intc/arm_gicv3_redist: Implement gicv3_redist_mov_vlpi() Implement the gicv3_redist_mov_vlpi() function (previously left as a stub). This function handles the work of a VMOVI command: it marks the vLPI not-pending on the source and pending on the destination.
