  • Publication number: 20220147455
    Abstract: A system-on-chip with runtime global push to persistence includes a data processor having a cache, an external memory interface, and a microsequencer. The external memory interface is coupled to the cache and is adapted to be coupled to an external memory. The cache provides data to the external memory interface for storage in the external memory. The microsequencer is coupled to the data processor. In response to a trigger signal, the microsequencer causes the cache to flush the data by sending the data to the external memory interface for transmission to the external memory.

  • Publication number: 20220100870
    Abstract: Systems, apparatuses, and methods for implementing a metadata tweak for channel encryption differentiation are disclosed. A memory controller retrieves a device-unique identifier (ID) from a memory device coupled to a given memory channel slot. The memory controller uses the device-unique ID to generate a tweak value used for encrypting data stored in the device. In one scenario, the device-unique ID is embedded in the address bits of the tweak process. In this way, the memory device can be migrated to a different memory channel since the data can be decrypted independently of the channel. This is possible since the device-unique ID used for the tweak operation is retrieved from the metadata stored locally on the memory device. In one implementation, the memory device is a persistent dual in-line memory module (DIMM). In some implementations, the link between memory controller and memory device is a compute express link (CXL) compliant link.

  • Patent number: 10423294
    Abstract: A method includes receiving reports of the pointing device events occurring on a remote computer at a host computer and performing computations in the host computer based upon the mouse reports. The method includes generating screen images in the host computer based upon the computations, the screen images not containing images of a cursor representing locations pointed to by a pointing device of the host computer. The generated screen images are transmitted to the remote computer. In some embodiments, the reports may be received by a remote console controller. An information handling system includes boot firmware to set a mouse to operate in absolute mode under control of the boot firmware. An information handling system separately transmits to a remote console controller of the information handling system screen images without a cursor and cursor images.

  • Publication number: 20190138730
    Abstract: An information handling system authenticates a key manifest of a memory with a hash of a key associated with the key manifest. When the key manifest is authentic, the system authenticates a boot policy manifest with the hash of first public key associated with the boot policy manifest. When the boot policy manifest is authentic, the system validates a pre-boot block of the memory based upon the hash of the pre-boot block stored in the boot policy manifest and directs a processor to execute the pre-boot code when the pre-boot block is valid. A processor executes the pre-boot code to execute a reset vector and to determine if the boot block is valid with hash of the boot block, and executes the boot code when the boot block is valid.

  • Patent number: 10216524
    Abstract: An information handling system includes a memory with a cache, and a processor to execute pre-operating system (pre-OS) code before the processor executes boot loader code. The pre-OS code sets up a Memory Type Range Register (MTRR) to define a first memory type for a memory region of the memory, sets up a page attribute table (PAT) with an entry to define a second memory type for the memory region, disables the PAT, and pass execution by the processor to the boot loader code. The first memory type specifies a first cacheability setting on the processor for data from the memory region, and the second memory type specifies a second cacheability setting on the processor for data from the memory region.

  • Patent number: 9619239
    Abstract: In accordance with embodiments of the present disclosure, a device for persistent cached image download may include a memory, an input/output interface, and a network interface. The memory may be configured to store therein an image database, the image database comprising a boot image for each of one or more information handling systems. The input/output interface may be communicatively coupled to the memory and configured to couple to a corresponding input/output port of an information handling system. The network interface may be configured to couple to an image server. In response to an information handling system coupled to the input/output interface determining that the updated version of the particular boot image exists at the image server, the memory may store the updated version in the memory as the particular boot image.

  • Publication number: 20110055838
    Abstract: A system and method for efficient dynamic scheduling of tasks. A scheduler within an operating system assigns software threads of program code to computation units. A computation unit may be a microprocessor, a processor core, or a hardware thread in a multi-threaded core. The scheduler receives measured data values from performance monitoring hardware within a processor as the one or more processors execute the software threads. The scheduler may be configured to reassign a first thread assigned to a first computation unit coupled to a first shared resource to a second computation unit coupled to a second shared resource. The scheduler may perform this dynamic reassignment in response to determining from the measured data values a first measured value corresponding to the utilization of the first shared resource exceeds a predetermined threshold and a second measured value corresponding to the utilization of the second shared resource does not exceed the predetermined threshold.

  • Publication number: 20090016355
    Abstract: A communication system, such as a computer system, with a plurality of processing nodes coupled by communication links stores a database of abstract topologies that provides a node adjacency matrix and abstract routing between nodes. A breadth-first discovery of the actual communication fabric is performed starting from an arbitrary root node to discover the actual topography. A graph isomorphism algorithm finds a match between the discovered topology and one of the stored abstract topologies. The graph isomorphism algorithm provides a mapping between the ‘abstract’ node numbers and the discovered node numbers. That mapping may be used to rework the stored routing tables into the specific format needed. The computed routing tables are loaded into the fabric starting at the leaf nodes, working back towards the root node (i.e., start loading from the highest node number and work back to the lowest numbered node).

  • Patent number: 7065688
    Abstract: In a system having a plurality of processing nodes, wherein each of the plurality of processing nodes has an assigned portion of system memory such that the assigned portion of system memory of each of the plurality of processing nodes is accessible by the plurality of processing nodes, a technique is presented that allows each of the plurality of processing nodes to perform a memory initialization and test of the processing node's assigned portion of system memory. One of the processing nodes can cause the others of the processing nodes to perform the memory initialization and test process or each processing node can automatically perform the memory initialization and test process.
