Copyright (C) 2021, Bin Meng <bmeng.cn@gmail.com>\n+\n+QEMU PPC E500\n+=============\n+\n+QEMU for PPC supports a special 'ppce500' machine designed for emulation and\n+virtualization purposes. This document describes how to run U-Boot under it.\n+\n+The QEMU ppce500 machine models a generic PowerPC E500 virtual machine with\n+support for the VirtIO standard networking device connected to the built-in\n+PCI host controller. Some common devices in the CCSBAR space are modeled,\n+including MPIC, 16550A UART devices, GPIO, I2C and PCI host controller with\n+MSI delivery to MPIC. It uses device-tree to pass configuration information\n+to guest software.\n+\n+Building U-Boot\n+---------------\n+Set the CROSS_COMPILE environment variable as usual, and run::\n+\n+ $ make qemu-ppce500_defconfig\n+ $ make\n+\n+Running U-Boot\n+--------------\n+The minimal QEMU command line to get U-Boot up and running is::\n+\n+ $ qemu-system-ppc -nographic -machine ppce500 -bios u-boot\n+\n+You can also run U-Boot using 'qemu-system-ppc64'::\n+\n+ $ qemu-system-ppc64 -nographic -machine ppce500 -bios u-boot\n+\n+The commands above create a target with 128 MiB memory by default. A freely\n+configurable amount of RAM can be created via the '-m' parameter. For example,\n+'-m 2G' creates 2 GiB memory for the target, and the memory node in the\n+embedded DTB created by QEMU reflects the new setting.\n+\n+Both qemu-system-ppc and qemu-system-ppc64 provide emulation for the following\n+32-bit PowerPC CPUs:\n+\n+* e500v2\n+* e500mc\n+\n+Additionally qemu-system-ppc64 provides support for the following 64-bit CPUs:\n+\n+* e5500\n+* e6500\n+\n+The CPU type can be specified via the '-cpu' command line. If not specified,\n+it creates a machine with e500v2 core. The following example shows an e6500\n+based machine creation::\n+\n+ $ qemu-system-ppc64 -nographic -machine ppce500 -cpu e6500 -bios u-boot\n+\n+When U-Boot boots, you will notice the following::\n+\n+ CPU: Unknown, Version: 0.0, (0x00000000)\n+ Core: e6500, Version: 2.0, (0x80400020)\n+\n+This is because we only specified a core name to QEMU and it does not have a\n+meaningful SVR value which represents an actual SoC that integrates such core.\n+You can specify a real world SoC device that QEMU has built-in support but all\n+these SoCs are e500v2 based MPC85xx series, hence you cannot test anything\n+built for P4080 (e500mc), P5020 (e5500) and T2080 (e6500).\n+\n+By default a VirtIO standard PCI networking device is connected as an ethernet\n+interface at PCI address 0.1.0, but we can switch that to an e1000 NIC by::\n+\n+ $ qemu-system-ppc -nographic -machine ppce500 -bios u-boot \\\n+ -nic tap,ifname=tap0,script=no,downscript=no,model=e1000\n+\n+VirtIO BLK driver is also enabled to support booting from a disk image where\n+a kernel image is stored. Append the following to QEMU::\n+\n+ -drive file=disk.img,format=raw,id=disk0 -device virtio-blk-pci,drive=disk0\n+\n+Pericom pt7c4338 RTC is supported so we can use the 'date' command::\n+\n+ => date\n+ Date: 2021-02-18 (Thursday) Time: 15:33:20\n+\n+Additionally, 'poweroff' command is supported to shut down the QEMU session::\n+\n+ => poweroff\n+ poweroff ...\n+\n+These have been tested in QEMU 5.2.0.\n", "prefixes": [ "v3", "38/38" ] }
