摘要： A method of authenticating shared peripheral component interconnect express devices of a switched fabric includes associating at least one requester identifier with a physical function of a device on the switched fabric and instantiating a virtual function of the device based on the physical function. The virtual function includes the associated at least one requester identifier. The method further includes accepting memory-mapped input/output traffic through the virtual function only from a requester having a corresponding requester identifier matching an associated requester identifier of the virtual function. The method may also include allowing a write operation of the virtual function or the physical function only to an address residing within an allowable address range associated with the device.

摘要： A method and apparatus are provided to perform live migration of a guest in a computer system using device assignment. In this method and apparatus, one or more pages of the guest are copied to a target computer system. It is determined which pages have been copied, and what incremental changes have been made to the pages that were copied. For example, the incremental changes may be indicated to a hypervisor of an initial host of the guest by a network interface controller or other device in the computer system. The incremental changes are then copied to the target computer system. Detection and copying of incremental changes may continue until a time when all dirty pages can be copied to the target computer system.

摘要： An apparatus includes an interface module, a controller, a key storage module, where the key storage module is configured to store a key, and a non-volatile storage module that is configured to store data. The non-volatile storage module has a first partition and a second partition, where the first partition is designated as a read-only storage area for the data and the second partition is designated as a write-only storage area for new data. The first partition is re-designated as the write-only storage area for other new data and the second partition is re-designated as the read-only storage area for the new data in response to the new data being written to the second partition with a signature and the controller verifying the signature using the key stored in the key storage module.

摘要： An example of a system and method implementing a live migration of a guest on a virtual machine of a host server to a target server is provided. For example, a host server may utilize a flow key to encrypt and decrypt communications with a target server. This flow key may be encrypted using a receive master key, which may result in a receive token. The receive token may be sent to the Network Interface Controller of the host server, which will then encrypt the data packet and forward the information to the target server. Multiple sender schemes may be employed on the host server, and various updates may take place on the target server as a result of the new location of the migrating guest from the host server to the target server.

摘要： Aspects of the disclosure relate to directing and tracking translation lookaside buffer (TLB) shootdowns within hardware. One or more processors, comprising one or more processor cores, may determine that a process executing on a processing core causes one or more virtual memory pages to become disassociated with one or more previously associated physical memory addresses. The processing core which is executing that process which caused the disassociation may generate a TLB shootdown request. The processing core may transmit the TLB shootdown request to the other cores. The TLB shootdown request may include identification information, a shootdown address indicating the disassociated virtual memory page or pages which need to be flushed from the respective TLBs of the other cores, and a notification address indicating where the other cores may acknowledge completion of the TLB shootdown request.

摘要： A method of accessing data in a non-volatile memory device is disclosed. The method includes serially receiving a command having an address in a virtual address space. When the address maps to the buffer in memory, the address may be matched to the address to one of a plurality of segments in buffer memory. Data may be moved from internal EEPROM/Flash memory to a segment of the plurality of segments of the buffer memory for an address range in the virtual address space that is likely to be read. A physical address may be generated within the buffer memory based on the address. Data may be fetched in the buffer memory based on the generated address and then a response for the command may be transmitted that includes the fetched data.

摘要： A method in a memory system having a security device and a serial external electrically erasable read-only memory (EEPROM) is disclosed. The method includes accepting N bits of a command prefix and matching the bits to command filtering rules. Upon matching the prefix to a command filtering rule, the method may perform a filter action associated with the matched rule. When the command prefix is for a destructive command prefix that can modify data in the EEPROM, the filter action may convert the command into a non-destructive command and inspect it for authentication. The converted command may be output to the external EEPROM without security processing in the security device and the external EEPROM may return read data without outputting. When the command prefix is for a non-destructive command prefix, the command may be allowed to pass through the external EEPROM unchanged without performing security processing in the security device.

摘要： A method includes deploying non-volatile random access memory (NVRAM) coupled to a processor or central processing unit (CPU) core of a computing device as a peripheral device via an input/output (I/O) bus, and providing a NVRAM application programming interface (API) for the CPU core to conduct NVRAM read and write operations. Providing the NVRAM API includes allocating a single memory buffer per command to hold data transferred to or from the NVRAM. The method includes configuring the processor in conjunction with the NVRAM API to set up command queues inside in the host Memory Mapped Input Output (MMIO) space.

摘要： A method for reading a first data bit from a non-volatile memory of a memory system is disclosed. The N most-significant bits are stored for each of M words in a rotated storage section. Address bits are serially received according to the clock signals. Before receiving a final address bit, a rotated word made up of the most significant bit of the M words is fetched from the rotated storage section. Address bits are serially received and rotated words are fetched until the N most-significant bits of the M words have been fetched. Then, un-rotated words are serially fetched from the non-volatile memory. Within one clock signal of the final address bit receipt, a bit is selected out of the fetched rotated words based on the received address bits. The first data bit is returned based on the selected bit and un-rotated words are returned based on the address.
