Abstract
Examples described herein relate to a device including circuitry to permit or deny the device to write-to or read-from kernel space memory of a virtualized execution environment by use of multiple process identifiers. In some examples, the device is communicatively coupled with the virtualized execution environment in a manner consistent with one or more of: Single Root IO Virtualization (SR-IOV), Scalable I/O Virtualization (SIOV), or PCI express (PCIe). In some examples, to control write or read operations to kernel space memory of a virtualized execution environment by the device by use of multiple process identifiers, the circuitry is to perform an address translation based on a first process identifier and second process identifier associated with the virtualized execution environment.
