Release RVVM v0.6 · LekKit/RVVM

This release includes

Prebuilt rvvm-cli & librvvm v0.6 for Linux, Windows, MacOS x86_64
More builds will be added later or should build from source
Prebuilt riscv64 U-Boot 2024.1 fw_payload.bin EFI firmware; With NVMe & EFIFB support patches, has framebuffer console
Prebuilt riscv64 Arch RISC-V image with networking, nano, sshd. Credentials are root:riscv. Built with archriscv-scriptlet, with mkinitcpio config for faster boot, no firmware
Prebuilt riscv64 Debian image, see dqib. Notice they don't have framebuffer & I2C-HID enabled in the kernel. Credentials: root:riscv
Prebuilt riscv64 OpenSBI 1.4 fw_jump.bin for use as an SBI bootrom with a custom kernel payload. Generic upstream OpenSBI works too.
Prebuilt riscv64 static Linux 6.8.1 kernel Image linux_6.8 for tinkering
See LekKit/patches-misc for firmware/kernel configs, patches and more

To boot a generic distro/EFI image, use rvvm fw_payload.bin -m 2G -i archriscv.img. Be aware some images may be slow to boot, and usually need more than default 256M of RAM.
Arch RISC-V image is included with full support. Debian lacks framebuffer/i2c-hid drivers in their kernel, but is otherwise functional over uart/ssh.
Generic Ubuntu 23.10 image works, but is overall bloated: https://cdimage.ubuntu.com/releases/23.10/release/ubuntu-23.10-preinstalled-server-riscv64.img.xz. Press Enter over the UART (your terminal) at GRUB screen. Credentials: ubuntu:ubuntu. Xorg lags heavily because of a bug in an older version, disable HW accel in xorg config.
FreeBSD 13.3 works: https://download.freebsd.org/snapshots/VM-IMAGES/13.3-STABLE/riscv64/Latest/FreeBSD-13.3-STABLE-riscv-riscv64.raw.xz. Credentials: root:root, use # kldload if_re to load networking driver.
To boot a rootfs inside an image with a static kernel payload, use rvvm fw_jump.bin -k linux_6.8 -i rootfs.img. This is useful for distros without an official bootable image, like Buildroot, and is usually faster. If your image doesn't directly contain a root filesystem, you can pass -append root=/dev/nvme0n1p1 or the likes to the RVVM, and this cmdline will reach the guest kernel

Networking is now stable and enabled by default
Allow port forwarding to the guest with -portfwd 127.0.0.1:8080=80
Support relative mouse movement, grabbing the host mouse
Support international keyboard layouts (I.e. keys specific to Japanese, Korean, German etc keyboards)
Optional SDL2 GUI backend
Support Big-endian hosts (MIPS64, PowerPC64) properly
SiFive GPIO support
MTD physmap firmware chip
Dallas DS1742 Real-time clock
Support (multiple) PTY or UNIX sockets as UART character device with -serial [file], silent UART with -serial null;
Support explicitly choosing NVMe or ATA with -ata [img] or -nvme [img]
Support using host block devices (/dev/sda, /dev/mmcblk) as RVVM drives
Faster threaded IO implementation
Faster UART console (Especially on Windows, Serenity)
Optimized Win32 display rendering
Slightly better RVJIT x86 register allocation
RVJIT significantly optimizes memory accesses with userland CPU emulation (To the point of near-native perf of user emulation)
Rework CMake build system to build shared librvvm properly
Colorful logger
Libretro port
[WIP] Began work on a Linux userspace binary emulator. Many riscv64 glibc binaries work, but threading and JIT caches are flaky.

Character device API
GPIO API
Provide a separate mapping property for direct MMIO regions
Omit PC increment for traps in Userland API
Support non-canonical framebuffer stride
Return rvvm_mmio_handle_t upon attaching most de-attachable MMIO devices
Implement RVVM_OPT_MEM_BASE, RVVM_OPT_MEM_SIZE to query RAM configuration of the machine.
Implement RVVM_OPT_HART_COUNT to query amount of cores
Java JNI bindings
