Prebuilt RVVM EFI firmware (OpenSBI 1.4, U-Boot 2024.7)

Recommended firmware for RVVM riscv64 (Works under QEMU as well)

HOWTO:

• Use fw_payload.bin as a board EFI firmware to boot the next stage from the storage drive, this is recommended for existing OS images like Ubuntu, Fedora, FreeBSD, Haiku, and for images built with archriscv-scriptlet.
• Be aware that some images like Ubuntu may require more than default 256M of RAM, otherwise they'll crash. Pass -m 2G or the likes to the VM to be sure.

Example usage: rvvm fw_payload.bin -m 2G -i haiku-nightly.image

Also:

• Use fw_jump.bin as an SBI bootrom for a custom kernel payload (SBI->Linux, etc) - see https://github.com/LekKit/patches-misc/releases/tag/rvvm-linux-6.8

The fw_payload.bin EFI firmware is a combination of fw_jump.bin M-mode bootrom, and u-boot.bin S-mode firmware

• Upstream OpenSBI 1.4: https://github.com/riscv-software-src/opensbi
• U-Boot 2024.7 with NVMe and EFIFB support enabled

Prebuilt RVVM Linux kernel payload (Linux 6.8)

Tiny static kernel that works regardless of the distro and doesn't need a bootloader.
Use this to manually run distributions without using U-Boot, like Buildroot, Arch Linux RISC-V, Debian, etc

HOWTO:

• Use fw_jump.bin as a firmware, see https://github.com/LekKit/patches-misc/releases/tag/rvvm-uboot-2023.4
• Use linux_6.8 as a kernel payload, i.e. add -k linux_6.8 to RVVM args
• Put your rootfs onto the storage drive, add -append "root=/dev/[root dev]" to RVVM args if your rootfs is not on /dev/nvme0n1

Sources:

• Mainline Linux: https://kernel.org/
• Patches i2c-hid-hang-fix, linux-shrink and config config-tiny-6.8 from this repo

Prebuilt RVVM Linux kernel payload (Linux 6.7)

Tiny static kernel that works regardless of the distro and doesn't need a bootloader.
Use this to manually run distributions without using U-Boot, like Buildroot, Arch Linux RISC-V, Debian, etc

HOWTO:

• Use fw_jump.bin as a firmware, see https://github.com/LekKit/patches-misc/releases/tag/rvvm-uboot-2023.4
• Use linux_6.7 as a kernel payload, i.e. add -k linux_6.7 to RVVM args
• Put your rootfs onto the storage drive, add -append "root=/dev/[root dev]" to RVVM args if your rootfs is not on /dev/nvme0n1

Prebuilt RVVM firmware (OpenSBI 1.2, U-Boot 2023.4)

This is a recommended firmware combination for RVVM riscv64 (Works under QEMU as well)

HOWTO:

• Use fw_jump.bin as a firmware, also usable for a custom kernel payload (SBI->Linux, etc)
• Use u-boot.bin as a kernel payload to boot the next stage from the storage drive (SBI->U-Boot->EFI->...), this is recommended for existing OS images like Ubuntu, Fedora, FreeBSD, Haiku

The fw_payload.bin combines OpenSBI and U-Boot into a single firmware so you can do rvvm fw_payload.bin -i haiku-nightly.img without extra typing. It may be also flashed onto emulated FW chip in future.

• Upstream OpenSBI 1.2: https://github.com/riscv-software-src/opensbi
• U-Boot 2023.4 with NVMe and EFIFB support enabled: https://github.com/u-boot/u-boot/tree/v2023.04

Prebuilt RVVM Linux kernel payload (Linux 6.2)

Tiny static kernel that works regardless of the distro and doesn't need a bootloader.
Use this to manually run distributions without an official U-Boot/EFI image, like Buildroot, Arch Linux RISC-V, Debian, etc

HOWTO:

• Use fw_jump.bin as a firmware, see https://github.com/LekKit/patches-misc/releases/tag/rvvm-uboot-2023.4
• Use linux_6.2 as a kernel payload, i.e. add -k linux_6.2 to RVVM args
• Put your rootfs onto the storage drive, add -append "root=/dev/[root dev]" to RVVM args if your rootfs is not on /dev/nvme0n1
