Examples described herein relate to dynamically adjust a manner of identifying hot pages in a remote memory pool based on adjustment of parameters of a data structure. In some examples, the parameters of the data structure include a range of number of access counts and a number of pages associated with the range.

A processor implementing techniques to supporting fault information delivery is disclosed. In one embodiment, the processor includes a memory controller unit to access an enclave page cache (EPC) and a processor core coupled to the memory controller unit. The processor core to detect a fault associated with accessing the EPC and generate an error code associated with the fault. The error code reflects an EPC-related fault cause. The processor core is further to encode the error code into a data structure associated with the processor core. The data structure is for monitoring a hardware state related to the processor core.

A die read counter and a block read counter are maintained for a specified block of a memory device. An estimated number of read events associated with the specified block is determined based on a value of the block read counter and a value of the die read counter. Responsive to determining that the estimated number of read events satisfies a criterion, a media management operation of one or more pages associated with the specified block is performed.

Systems and methods are disclosed for virtualized caches. For example, an integrated circuit (e.g., a processor) for executing instructions includes a virtually indexed physically tagged first-level (L1) cache configured to output to an outer memory system one or more bits of a virtual index of a cache access as one or more bits of a requestor identifier. For example, the L1 cache may be configured to operate as multiple logical L1 caches with a cache way of a size less than or equal to a virtual memory page size. For example, the integrated circuit may include an L2 cache of the outer memory system that is configured to receive the requestor identifier and implement a cache coherency protocol to disambiguate an L1 synonym occurring in multiple portions of the virtually indexed physically tagged L1 cache associated with different requestor identifier values.
