The SoftIron Overdrive 3000 is an ARMv8 based server with an 8-core AMD Opteron A1100 processor. The Overdrive 3000 has two 10Gbase-T ethernet ports, two PCI Express ports, and eight SATA ports. FreeBSD has been updated to be able to boot on this hardware.

Support for the SATA device was added to the ahci(4) driver. Unlike on x86 this is a Memory Mapped (mmio) device, and no on the PCI bus. To support this a new ahci mmio driver attachment has been added.

The generic PCIe driver has been updated to improve interrupt handling. This included supporting the interrupt-map devicetree property, and supporting MSI and MSI-X interrupts on arm64.

Support for MSI and MSI-X interrupts has been added to the ARM Generic Interrupt Controller v2 (gicv2) driver. This allows devices to use these interrupts. This has been tested with a collection of PCIe NIC hardware.
