From fef592f909e99fc4a4a600879b3d64b3bb130fa5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 15 Jan 2018 19:04:05 +0100 Subject: [PATCH] ppc/pnv: change initrd address MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When skiboot starts, it first clears the CPU structs for all possible CPUs on a system : for (i = 0; i <= cpu_max_pir; i++) memset(&cpu_stacks[i].cpu, 0, sizeof(struct cpu_thread)); On POWER9, cpu_max_pir is quite big, 0x7fff, and the skiboot cpu_stacks array overlaps with the memory region in which QEMU maps the initramfs file. Move it upwards in memory to keep it safe.
