摘要： Instructions and logic provide vector loads and/or stores with stride and mask functionality. Some embodiments, responsive to an instruction specifying: a set of loads, destination register, mask register, memory address, and stride length; execution units read values in the mask register, wherein fields in the mask register correspond to stride-length multiples from the memory address to data elements in memory. A first mask value indicates the element has not been loaded from memory and a second value indicates that the element does not need to be, or has already been loaded. For each having the first value, the corresponding multiple of said stride length is generated according to the data field's position in the mask register to load the data element from memory into the corresponding destination register location, and the corresponding value in the mask register is changed to the second value. These instructions can restart after faults.

摘要： A processor core including a hardware decode unit to decode vector instructions for decompressing a run length encoded (RLE) set of source data elements and an execution unit to execute the decoded instructions. The execution unit generates a first mask by comparing set of source data elements with a set of zeros and then counts the trailing zeros in the mask. A second mask is made based on the count of trailing zeros. The execution unit then copies the set of source data elements to a buffer using the second mask and then reads the number of RLE zeros from the set of source data elements. The buffer is shifted and copied to a result and the set of source data elements is shifted to the right. If more valid data elements are in the set of source data elements this is repeated until all valid data is processed.

摘要： Technologies for virtual multipath access include a computing device configured to sequester a recovery partition from a host partition while allowing the recovery partition to access one or more resources of the host partition such as host memory or data storage. A remote computing device determines whether the host partition is responsive. The recovery partition receives a request for host state data of the host partition from the remote computing device in response to a determination that the host partition is not responsive. The recovery partition retrieves the requested host state data using a host state index maintained by the host partition and transmits the requested host state data to the remote computing device. The host state index may identify the location of the requested host state data. The remote computing device may perform a recovery operation based on the received host state data. Other embodiments are described and claimed.

摘要： Systems and methods that include kernel address detection circuitry to identify a current privilege level (CPL) of a speculatively executed instruction as either a kernel-level instruction or a user-level instruction are provided. For instructions identified as kernel-level, the kernel address detection circuitry permits access to all or a portion of both kernel memory space and user memory space within the system memory. For instructions identified as user-level, the kernel address detection circuitry permits access to all or a portion of the user memory space within the system memory. If a user-level instruction attempts to access a physical memory address within the defined kernel memory space, the kernel address detection circuitry generates an exception and does not provide the user-level instruction access to the physical address in the kernel memory space. Thus, the systems and methods prevent memory accesses used in side channel attacks such as Meltdown.
