Our FreeBSD Expertise

We excel in FreeBSD kernel development, userspace applications, and virtualization projects. With expertise in ZFS, ARM/RISC-V porting, and bhyve, we deliver optimized solutions across various industries. 

FreeBSD Complex Projects

Support and maintain the FreeBSD distribution for the functional safety projects, which include

Porting system for the dedicated baseboard.

Adapting the distributions to fulfil the requirements.

Creating documentation for the safety assessment.

Creating the SDK for building applications on Linux systems.

Root cause analysis for the issues reported from the field.

bhyve Virtualization Contributions

  1. ZFS event framework

    • We create a framework for generating events in the XML format and sending them via devctl(4) to the userspace. Implemented reporting of various ZFS events related to pool, dev, dataset, and snapshot management.

  2. NextBSD

    • FreeBSD kernel support for Mach IPC. Support for zero-copy passing of memory segments, file descriptors, and a functional launch port.

  3. FreeBSD/arm+riscv ports

    • Our team successfully ported FreeBSD to a variety of ARM and RISC-V platforms, including:
      • Texas Instruments DaVinci (ARM9)
      • NXP LPC32x0 (ARM9)
      • Marvell MV78100 (ARM9)
      • Microchip PolarFire SoC (RISC-V 64)

  4. INTRNG

      • The interrupt routing framework for ARM (now used on other platforms as well) allows the use of multiple, nested interrupt controllers (for example, GPIO chips with interrupt capability).

  1. py-libzfs

    • We develop comprehensive Cython bindings for libzfs and libzfs-core, enabling full ZFS management functionality in Python. This solution is ideal for automated storage management, provisioning, and monitoring.

  2. devd-xml

    • We refactor FreeBSD’s devctl(4) event format, transitioning from key-value pair strings to XML. This allows for richer metadata in event messages, making it easier to handle complex ZVOL names and improving system integration.

  3. Cython Libraries

    • We develop several high-performance Cython bindings for FreeBSD APIs, empowering developers to leverage FreeBSD’s functionality in Python:
      • py-bsd: Provides bindings for ACLs, BPF, GEOM, sysctl, and more.
      • py-netif: Simplifies network interface and routing configuration.
      • py-cam: Offers access to CAM functions for storage device management.
      • py-pf: A powerful interface for managing FreeBSD’s packet filter (PF).

  1. Virtio-9p Development

    • We implement Virtio-9p (VirtFS) for bhyve, enabling efficient filesystem sharing between the host OS and guest virtual machines. This technology is critical for use cases requiring real-time file access across environments.

  2. LibVNC Integration

    • Our team integrates LibVNC into bhyve, replacing the original RFB server to deliver better performance and a superior user experience, particularly for FreeNAS users.

  3. Virtio-SCSI and Intel E1000 Driver

    • We contribute to the development of virtio-scsi, facilitating the sharing of SCSI LUNs with virtual machines, and helped integrate the emulated Intel E1000 network card, improving network performance in bhyve environments.
