Described are techniques for write protecting a non-volatile memory (NVM) after the contents of the NVM have been set. In some examples, a computing device or system having an NVM also includes a Root of Trust (RoT) configured to generate a write protect command as an input to the NVM. The RoT generates the write protect command in response to detecting a write protect signal from an electronic controller. The write protect command sets one or more areas in the NVM to be read-only. Further, the write protect command can make the one or more areas read-only on a power-on basis so that write protection is maintained until the next power cycle. The electronic controller can be configured to assert the write protect signal each time the computing device or system is powered on, for instance during a reboot, thereby causing the RoT to renew the write protection.

A host server computer with an uncorrectable memory error can be repaired without a reboot operation. While initially booting a hypervisor, a special software Application Programming Interface (API) can be loaded between a BIOS System Management Mode (SMM) code and the hypervisor. Once the host server computer is booted and a number of virtual machines are executing, a memory error (e.g., uncorrectable error correction code (UECC)) can occur. In response, the hypervisor calls into the special software API identifying the defective memory rows that the BIOS needs to repair. The BIOS starts a soft Post Package Repair (PPR) process on those rows and gives back control to the hypervisor. When the repair is completed, the hypervisor loads a scrubbing virtual machine and validates that the memory is corrected. After the repair is validated, the hypervisor allows the available partition to take a new customer instance.

A microprocessor includes a macro-op (MOP) cache (MOC) having MOC entries (MEs) holding MOPs. An instruction fetch circuit fetches from the MOC the MOPS of an ME for execution, and a back-end detects that a MOP of the ME is causing a need for an abort type within a predetermined subset of abort types. A control circuit uses a location within the ME of the abort-causing MOP to determine an abort point that separates the ME into a former portion and a latter portion, flushes the MOPs of the latter portion of the ME, and allows the MOPs of the former portion of the ME to execute. After the flush of the MOPs of the latter portion of the ME, the microprocessor re-fetches and executes the MOPs of the latter portion of the ME but does not re-execute the MOPs of the former portion of the ME.

The invention relates to a trusted chain reconstruction method, which is applied to independently restarting a system on a system-on-chip (SoC). In the trusted chain reconstruction method, aiming at an SoC comprising a plurality of systems, a detection component is operated on the SoC to detect the operation condition of the systems on the SoC, and when the detection component detects that a first system on the SoC needs to be restarted, the detection component transmits restarting information to a previous-level node (namely a first component) of the first system on a trusted chain, the first component is instructed to execute restart on the first system. In this way, the first component can re-execute the trusted startup process of the first system, and it is ensured that the first system can be safely restarted. According to the scheme, the trusted starting process of the system is executed only by the previous-level node of the system, which is equivalent to rebuilding a part of the trusted chain of the SoC, and the whole trusted chain of the SoC does not need to be rebuilt, so that the restarting time of the system can be shortened, and normal operation of other systems on the SoC is not influenced.

During or after booting of the IHS, a request is detected for a diagnostic boot cycle by a requestor, such as by the operating system of the IHS. When a diagnostic boot cycle has been requested, an EC (Embedded Controller) of the IHS is booted in a diagnostic mode to perform a diagnostic test on one or more hardware components of the IHS. The results of the diagnostic test are stored to the NVRAM (Non-Volatile Random-Access Memory) that stores the boot code and that is accessible to the requestor of the diagnostic test once the IHS has been rebooted to a non-diagnostic mode.

Systems and methods for flushing an operation log journal to both ephemeral storage and persistent storage during a shutdown sequence of a virtual storage system to minimize data-loss scenarios are provided.

In this manner, when the virtual storage system is rehosted after an unplanned shutdown or reboot resulting from an unrecoverable host error (other than an unrecoverable hardware failure), the operation log journal may be recovered from persistent storage to facilitate vNVRAM replay and avoid data loss.
