Dear QEMU developers, Hereby I would like to contribute the following set of patches to QEMU which add support for the Allwinner H3 System on Chip and the Orange Pi PC machine. The following features and devices are supported: * SMP (Quad Core Cortex A7) * Generic Interrupt Controller configuration * SRAM mappings * Timer device (re-used from Allwinner A10) * UART * SD/MMC storage controller * EMAC ethernet connectivity * USB 2.0 interfaces * Clock Control Unit * System Control module * Security Identifier device Functionality related to graphical output such as HDMI, GPU, Display Engine and audio are not included. Recently released mainline Linux kernels (4.19 up to latest master) and mainline U-Boot are known to work. The SD/MMC code is tested using bonnie++ and various tools such as fsck, dd and fdisk. The EMAC is verified with iperf3 using -netdev socket. To build a Linux mainline kernel that can be booted by the Orange Pi PC machine, simply configure the kernel using the sunxi_defconfig configuration: $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make mrproper $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make sunxi_defconfig To be able to use USB storage, you need to manually enable the corresponding configuration item. Start the kconfig configuration tool: $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make menuconfig Navigate to the following item, enable it and save your configuration: Device Drivers > USB support > USB Mass Storage support Build the Linux kernel with: $ ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j5 To boot the newly build linux kernel in QEMU with the Orange Pi PC machine, use: $ qemu-system-arm -M orangepi -m 512 -nic user -nographic \ -kernel /path/to/linux/arch/arm/boot/zImage \ -append 'console=ttyS0,115200' \ -dtb /path/to/linux/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dtb Note that this kernel does not have a root filesystem. You may provide it with an official Orange Pi PC image [1] either as an SD card or as USB mass storage. To boot using the Orange Pi PC Debian image on SD card, simply add the -sd argument and provide the proper root= kernel parameter: $ qemu-system-arm -M orangepi -m 512 -nic user -nographic \ -kernel /path/to/linux/arch/arm/boot/zImage \ -append 'console=ttyS0,115200 root=/dev/mmcblk0p2' \ -dtb /path/to/linux/arch/arm/boot/dts/sun8i-h3-orangepi-pc.dtb \ -sd OrangePi_pc_debian_stretch_server_linux5.3.5_v1.0.img Alternatively, you can also choose to build and boot a recent buildroot [2] using the orangepi_pc_defconfig or Armbian image [3] for Orange Pi PC. To attach an USB mass storage device to the machine, simply append to the command: -drive if=none,id=stick,file=myimage.img \ -device usb-storage,bus=usb-bus.0,drive=stick U-Boot mainline can be build and configured using the orangepi_pc_defconfig using similar commands as describe above for Linux. To start U-Boot using the Orange Pi PC machine, provide the u-boot binary to the -kernel argument: $ qemu-system-arm -M orangepi -m 512 -nic user -nographic \ -kernel /path/to/uboot/u-boot -sd disk.img Use the following U-boot commands to load and boot a Linux kernel from SD card: -> setenv bootargs console=ttyS0,115200 -> ext2load mmc 0 0x42000000 zImage -> ext2load mmc 0 0x43000000 sun8i-h2-plus-orangepi-zero.dtb -> bootz 0x42000000 - 0x43000000 Looking forward to your review comments. I will do my best to update the patches where needed. With kind regards, Niek Linnenbank [1] http://www.orangepi.org/downloadresources/ [2] https://buildroot.org/download.html [3] https://www.armbian.com/orange-pi-pc/
Works well on my side with vanilla linux-4.9.13 built with gcc-8.3.0 + busybox and sun8i-h3-orangepi-one.dtb. Tested-by: KONRAD Frederic <frederic.kon...@adacore.com>
