Abstract: A processor includes a decode unit to decode an instruction that is to indicate a page of a protected container memory, and a storage location outside of the protected container memory. An execution unit, in response to the instruction, is to ensure that there are no writable references to the page of the protected container memory while it has a write protected state. The execution unit is to encrypt a copy of the page of the protected container memory. The execution unit is to store the encrypted copy of the page to the storage location outside of the protected container memory, after it has been ensured that there are no writable references. The execution unit is to leave the page of the protected container memory in the write protected state, which is also valid and readable, after the encrypted copy has been stored to the storage location.

Abstract: An integrated circuit includes protected container access control logic to perform a set of access control checks and to determine whether to allow a device protected container module (DPCM) and an input and/or output (I/O) device to communicate securely through one of direct memory access (DMA) and memory-mapped input/output (MMIO). The DPCM and the I/O device are allowed to communicate securely if it is determined that at least the DPCM and the I/O device are mapped to one another, an access address associated with the communication resolves into a protected container memory, and a page of the protected container memory into which the access address resolves allows for the aforementioned one of DMA and MMIO. In some cases, a Security Attributes of Initiator (SAI) or security identifier may be used to obtain a DPCM identifier or attest that access is from a DPCM mapped to the I/O device.

Abstract: The invention relates to means for the autogenous grinding, separation and drying of various solid materials in a continuous process and can be used in many branches of industry. The technical result consists in creating a high-speed, powerful and at the same time energy-efficient, simple and reliable device and method for breaking up an initial stock and simultaneously drying particles of the ground stock. The technical result is achieved by feeding an initial stock into a grinding working area, grinding the initial stock and drying particles of the ground initial stock and discharging the ground and to a certain extent the dried particles of the initial stock outwards, with the initial stock being fed in and the dried particles of the ground stock being discharged by rotation of working flywheels.

Abstract: Instructions and logic provide advanced paging capabilities for secure enclave page caches. Embodiments include multiple hardware threads or processing cores, a cache to store secure data for a shared page address allocated to a secure enclave accessible by the hardware threads. A decode stage decodes a first instruction specifying said shared page address as an operand, and execution units mark an entry corresponding to an enclave page cache mapping for the shared page address to block creation of a new translation for either of said first or second hardware threads to access the shared page. A second instruction is decoded for execution, the second instruction specifying said secure enclave as an operand, and execution units record hardware threads currently accessing secure data in the enclave page cache corresponding to the secure enclave, and decrement the recorded number of hardware threads when any of the hardware threads exits the secure enclave.

Abstract: A secure enclave circuit stores an enclave page cache map to track contents of a secure enclave in system memory that stores secure data containing a page having a virtual address. An execution unit is to, in response to a request to evict the page from the secure enclave: block creation of translations of the virtual address; record one or more hardware threads currently accessing the secure data in the secure enclave; send an inter-processor interrupt to one or more cores associated with the one or more hardware threads, to cause the one or more hardware threads to exit the secure enclave and to flush translation lookaside buffers of the one or more cores; and in response to detection of a page fault associated with the virtual address for the page in the secure enclave, unblock the creation of translations of the virtual address.

Abstract: Instructions and logic support suspending and resuming migration of enclaves in a secure enclave page cache (EPC). An EPC stores a secure domain control structure (SDCS) in storage accessible by an enclave for a management process, and by a domain of enclaves. A second processor checks if a corresponding version array (VA) page is bound to the SDCS, and if so: increments a version counter in the SDCS for the page, performs an authenticated encryption of the page from the EPC using the version counter in the SDCS, and writes the encrypted page to external memory. A second processor checks if a corresponding VA page is bound to a second SDCS of the second processor, and if so: performs an authenticated decryption of the page using a version counter in the second SDCS, and loads the decrypted page to the EPC in the second processor if authentication passes.
