The AutumnOS Project

AutumnOS is an Linux-based operating system project developed for RV64 (RISC-V) architectures.

Interesting Features

• Dual Audio Subsystem: An audio subsystem which supports OSS and ALSA
• ChatTunnel: A SHM based IPC communication mechanism.
• AutixSurf: Layer manager for window manager. (ON WORK)
• Tabloader: A kernel driver which loads HAL and API tables globally. (ON WORK)
• Coder: A kernel driver which generates a status code for trigger an event on userspace / like IPC communicating but in kernel-space. (ON WORK)
• Symbol loader: An installer for API and HAL libraries before SysUI process.
• Autumn Virtual Machine: A memfd based virtual machine for handling heavy processes.
• Whike: AutumnOS's own C standard like library (includes math and

Tested Hardwares

• Allwinner D1 - MangoPi MQ-Pro (Pink Variation/ v1.4): RSOD driver and session working successfully.
• QEMU: Worked perfectly.

Working drivers on QEMU VM test:

• DRM
• Dual Audio Subsystem (I tested only OSS)
• Ethernet (No exception but not sure)
