Abstract
The goals of this study are: (i) to compare Linux kernel (2.4.22) behavior under a broad range of errors on two target processors - the Intel Pentium 4 (P4) running RedHat Linux 9.0 and the Motorola PowerPC (G4) running YellowDog Linux 3.0 - and (ii) to understand how architectural characteristics of the target processors impact the error sensitivity of the operating system. Extensive error injection experiments involving over 115,000 faults/errors are conducted targeting the kernel code, data, stack, and CPU system registers. Analysis of the obtained data indicates significant differences between the two platforms in how errors manifest and how they are detected in the hardware and the operating system. In addition to quantifying the observed differences and similarities, the paper provides several examples to support the insights gained from this research.
本研究的目标是:(i)比较两个目标处理器(运行RedHat Linux 9.0的英特尔Pentium 4 (P4)和运行YellowDog Linux 3.0的摩托罗拉PowerPC (G4))在广泛错误下的Linux内核(2.4.22)行为;(ii)了解目标处理器的架构特征如何影响操作系统的错误敏感性。针对内核代码、数据、堆栈和CPU系统寄存器进行了广泛的错误注入实验，涉及超过115,000个错误/错误。对获得的数据的分析表明，在硬件和操作系统中错误的显示方式和检测方式方面，这两个平台之间存在显著差异。除了量化观察到的差异和相似性之外，本文还提供了几个例子来支持从本研究中获得的见解。
