Abstract

Performing directed switches between user mode schedulable (UMS) threads and primary threads enable proper execution of the UMS threads. A primary thread user portion is switched to a UMS thread user portion so that the UMS thread user portion is executed in user mode via the primary thread user portion. The primary thread is then transferred into kernel mode via an implicit switch. A kernel portion of the UMS thread is then executed in kernel mode using the context information of a primary thread kernel portion.
