Abstract: Disclosed are various examples of signaling host kernel crashes to a data processing unit (DPU) management operating system (OS). A host kernel crash handler is installed to a host device. A crash of a host kernel of the host device is detected. This triggers the host kernel crash handler to provide the signal to the DPU device, which executes a DPU side crash handling process based on the signal.

Abstract: Disclosed are various examples of provisioning a data processing unit (DPU) management operating system (OS). A management hypervisor installer executed on a host device launches or causes a server component to provide a management operating system (OS) installer image at a particular URI accessible over a network internal to the host device. A baseboard management controller (BMC) transfers the DPU management OS installer image to the DPU device. A volatile memory based virtual disk is created using the DPU management OS installer image. The DPU device is booted to a DPU management OS installer on the volatile memory based virtual disk. The DPU management OS installer installs a DPU management operating system to a nonvolatile memory of the DPU device on reboot of the DPU device.

Abstract: A method for booting a computer system includes: loading a first stage bootloader of a plurality of first stage bootloaders from a boot image based on a known configuration of the computer system; executing the first stage bootloader to identify a selected bootbank of a plurality of bootbanks in the boot image based on the known configuration of the computer system; executing, by the first stage bootloader, a second stage bootloader from the boot image with an instruction to boot from the selected bootbank; and executing, by the second stage bootloader, a binary file in the selected bootbank.
