I am getting the following error when trying to validate a reflowable epub that I exported from InDesign: ERROR(RSC-012): epub/OEBPS/toc.xhtml(63,94): Fragment identifier is not defined. Nothing I try is getting rid of the error. I've tried rebuilding the TOC in multiple way...
整个查找页表的过程一共要遍历三层,如果这三次查找有任意一次没有命中,即对应PTE不存在,这种异常的情况称为缺页错误Page-Fault。因为是一个异常,所以进程会陷入内核,由内核来处理缺页错误,然后一般地,内核为该进程调入所需的页面,更新并设置好页表的相关PTE,并且重新执行原用户指令。(但在xv6里,对于缺页错误的异常...
