Abstract

Systems, apparatuses and methods may provide for technology that sets a write protection flag in a guest command buffer associated with a virtual machine and injects a semaphore command into a shadow command buffer in response to a fault. The fault is to correspond to a write of a graphics command to the guest command buffer by code executing in graphics hardware. In one example, the technology also conducts a security scan of the graphics command in response to a context switch in the graphics hardware, wherein the context switch is to be associated with the semaphore command.
