Abstract
Systems for a method for monolithic workload scheduling in a portable computing device ('PCD') having a hypervisor are disclosed. An exemplary method comprises instantiating a primary virtual machine at a first exception level, wherein the primary virtual machine comprises a monolithic scheduler configured to allocate workloads within and between one or more guest virtual machines in response to one or more interrupts, instantiating a secure virtual machine at the first exception level and instantiating one or more guest virtual machines at the first exception level as well. When an interrupt is received at a hypervisor associated with a second exception level, the interrupt is forwarded to the monolithic scheduler along with hardware usage state data and guest virtual machine usage state data. The monolithic scheduler may, in turn, generate one or more context switches which may comprise at least one intra-VM context switch and at least one inter-VM context switch.
