Abstract: System and computer-implemented method enables a hardware watchdog timer in a data processing unit (DPU) and detects that a host server that is connected to the DPU is unresponsive when the hardware watchdog timer expires without receiving a timer reset request from a host watchdog service timer thread running in the host server.

Abstract: Systems and methods are described for secure management of a data processing unit (“DPU”). In an example, a baseboard management controller (“BMC”) can provision a DPU. Provisioning can include configuring a local storage device for DPU storage and locking access to the DPU storage with an encrypted access key. To boot the DPU, the BMC can initiate DPU firmware on the DPU. The DPU firmware can retrieve the access key from the BMC and unlock the DPU storage with the access key. The DPU firmware can be configured to then delete the access key. Once the DPU storage is unlocked, the DPU firmware can load an operating system of the DPU. The BMC can be the only entity that retains the access key. To perform a secure wipe, instructions can be provided to the BMC to delete the access key, which renders the DPU storage and all data therein inaccessible.

Abstract: System and method for analyzing operating systems uses information regarding access bits set in page table entries to identify code segments of an operating system that were not executed. These code segments are identified by first identifying untouched memory pages using the information regarding the access bits in the page table entries, and then identifying functions of the operating system using physical memory addresses for the untouched memory pages. The identified functions represent the code segments of the operating system that were not executed.

Abstract: System and computer-implemented method allocates log buffers at a host server, receives log data from a data processing unit (DPU) that is connected to the host server and stores the log data in the log buffers at the host server, and transmits the log data stored in the log buffers back to the DPU to be stored in storage of the DPU such that the host server is used to temporarily store the log data.
