It +is also possible to create a 32-bit variant with the same peripherals except +that the RISC-V cores are replaced by the 32-bit ones (E31 and U34), to help +testing of 32-bit guest software. + +Hardware configuration information +---------------------------------- + +The ``sifive_u`` machine automatically generates a device tree blob ("dtb") +which it passes to the guest. This provides information about the addresses, +interrupt lines and other configuration of the various devices in the system. +Guest software should discover the devices that are present in the generated +DTB instead of using a DTB for the real hardware, as some of the devices are +not modeled by QEMU and trying to access these devices may cause unexpected +behavior. + +Boot options +------------ + +The ``sifive_u`` machine can start using the standard -kernel functionality +for loading a Linux kernel, a VxWorks kernel, a modified U-Boot bootloader +(S-mode) or ELF executable with the default OpenSBI firmware image as the +-bios. It also supports booting the unmodified U-Boot bootloader using the +standard -bios functionality. + +Machine-specific options +------------------------ + +The following machine-specific options are supported: + +- serial=nnn + + The board serial number. When not given, the default serial number 1 is used. + + SiFive reserves the first 1 KiB of the 16 KiB OTP memory for internal use. + The current usage is only used to store the serial number of the board at + offset 0xfc. U-Boot reads the serial number from the OTP memory, and uses + it to generate a unique MAC address to be programmed to the on-chip GEM + Ethernet controller. When multiple QEMU ``sifive_u`` machines are created + and connected to the same subnet, they all have the same MAC address hence + it creates an unusable network. In such scenario, user should give different + values to serial= when creating different ``sifive_u`` machines. + +- start-in-flash + + When given, QEMU's ROM codes jump to QSPI memory-mapped flash directly. + Otherwise QEMU will jump to DRAM or L2LIM depending on the msel= value. + When not given, it defaults to direct DRAM booting. + +- msel=[6|11] + + Mode Select (MSEL[3:0]) pins value, used to control where to boot from. + + The FU540 SoC supports booting from several sources, which are controlled + using the Mode Select pins on the chip. Typically, the boot process runs + through several stages before it begins execution of user-provided programs. + These stages typically include the following: + + 1. Zeroth Stage Boot Loader (ZSBL), which is contained in an on-chip mask + ROM and provided by QEMU. Note QEMU implemented ROM codes are not the + same as what is programmed in the hardware. The QEMU one is a simplified + version, but it provides the same functionality as the hardware. + 2. First Stage Boot Loader (FSBL), which brings up PLLs and DDR memory. + This is U-Boot SPL. + 3. Second Stage Boot Loader (SSBL), which further initializes additional + peripherals as needed. This is U-Boot proper combined with an OpenSBI + fw_dynamic firmware image. + + msel=6 means FSBL and SSBL are both on the QSPI flash. msel=11 means FSBL + and SSBL are both on the SD card. + +Running Linux kernel +-------------------- + +Linux mainline v5.10 release is tested at the time of writing.

Hence the number of cores and size of memory have to match +the real hardware, ie: 5 cores (-smp 5) and 8 GiB memory (-m 8G). + +Above use case is to run upstream U-Boot for the SiFive HiFive Unleashed +board on QEMU ``sifive_u`` machine out of the box. This allows users to +develop and test the recommended RISC-V boot flow with a real world use +case: ZSBL (in QEMU) loads U-Boot SPL from SD card or SPI flash to L2LIM, +then U-Boot SPL loads the combined payload image of OpenSBI fw_dynamic +firmware and U-Boot proper. However sometimes we want to have a quick test +of booting U-Boot on QEMU without the needs of preparing the SPI flash or +SD card images, an alternate way can be used, which is to create a U-Boot +S-mode image by modifying the configuration of U-Boot: + +.. code-block:: bash + + $ make menuconfig + +then manually select the following configuration in U-Boot: + + Device Tree Control > Provider of DTB for DT Control > Prior Stage bootloader DTB + +This lets U-Boot to use the QEMU generated device tree blob.

Use the +``qemu-system-riscv64`` executable to simulate a 64-bit RISC-V machine, +``qemu-system-riscv32`` executable to simulate a 32-bit RISC-V machine. + +QEMU has generally good support for RISC-V guests. It has support for +several different machines. The reason we support so many is that +RISC-V hardware is much more widely varying than x86 hardware. RISC-V +CPUs are generally built into "system-on-chip" (SoC) designs created by +many different companies with different devices, and these SoCs are +then built into machines which can vary still further even if they use +the same SoC. + +For most boards the CPU type is fixed (matching what the hardware has), +so typically you don't need to specify the CPU type by hand, except for +special cases like the ``virt`` board. + +Choosing a board model +---------------------- + +For QEMU's RISC-V system emulation, you must specify which board +model you want to use with the ``-M`` or ``--machine`` option; +there is no default. + +Because RISC-V systems differ so much and in fundamental ways, typically +operating system or firmware images intended to run on one machine +will not run at all on any other.

(Once the kernel has booted, most user space software +cares much less about the detail of the hardware.) + +If you already have a system image or a kernel that works on hardware +and you want to boot with QEMU, check whether QEMU lists that machine +in its ``-machine help`` output. If it is listed, then you can probably +use that board model. If it is not listed, then unfortunately your image +will almost certainly not boot on QEMU. (You might be able to +extract the file system and use that with a different kernel which +boots on a system that QEMU does emulate.) + +If you don't care about reproducing the idiosyncrasies of a particular +bit of hardware, such as small amount of RAM, no PCI or other hard +disk, etc., and just want to run Linux, the best option is to use the +``virt`` board.
