摘要

在本文中，我们解释了当使用基于多核处理器的虚拟化层时锁持有人抢占(LHP)问题严重的原因。然后，我们介绍了两种避免LHP问题的新技术。现有的技术和新提出的技术已经在我们的虚拟化层SPUMONE上实现，我们测量的结果表明，提出的新技术减少了在嵌入式系统的多核处理器上使用虚拟化层的语义差距。

Solving the Lock Holder Preemption Problem in a Multicore Processor-based Virtualization Layer for Embedded Systems

In this paper, we explain the reason why the Lock Holder Preemption(LHP) problem is serious when using a multi-core processor based virtualization layer. Then, we introduce two new techniques for avoiding the LHP problem. The existing techniques and new proposed techniques have been implemented on our virtualization layer called SPUMONE, and we measured the results showing that the proposed new techniques reduce the semantic gap to use a virtualization layer on a multi-core processor in embedded systems.
