最近,我开始在"kern.log“和syslog中打印以下元素。
Jan 29 10:28:19 server kernel: [82515.307047] Page fault failed for pfn[0] = 0x0

nMaj -- Major Page Fault Count
The number of major page faults that have occurred for a task. A
page fault occurs when a process attempts to read from or write
to a virtual page that is not currently present in its address
space. **A major p
我有一个接受模型作为输入的函数
selectFault(fault: Fault) {
this.faultsService.setSelectedFault(fault)
this.router.navigate(['fault-detail']);
}
我已经为它生成了一个测试,但它报告了faultstub
error TS2693: 'Fault' only refers to a type, but is being used as a value here.
它抱怨的行是
{ provide: Fault, useVal
这样我就可以用
driver.get('https://www.w3.org/')
但是我想要测试的是,如果我给出一个错误链接,我应该得到类似
This page does not exist.
但是当我试图捕捉到这个,我无法得到结果
这是失败的,不能报告故障链接
link = "https://www.w3.org/fault_link"
if driver.find_elements_by_xpath("//*[contains(text(), 'This page does not exist')]"):
logg
在文件中,有一些关于页面错误代码的信息:
Page fault error code bits:
bit 0 == 0: no page found 1: protection fault
bit 1 == 0: read access 1: write access
bit 2 == 0: kernel-mode access 1: user-mode access
bit 3 == 1: use of reserved bit detected

我正在编写一个程序,要求浮点寄存器(xymm0-15)在页面错误后不被覆盖。我编写了下面的示例代码,生成一个页面错误,然后捕获它:
#include <signal.h>
#include <iostream>
using namespace std;
void handle(int, siginfo_t*, void* vcontext);
// Page fault handler. When this is called the fp registers are all zeroed
void handle(int, siginfo_t*, void* v
如果是这样,你能提供代码吗?我可以做几乎所有其他的事情,从创建新页面,修改页面属性等。但我似乎不能添加附件。我已经阅读了官方的,但它们显示的所有代码片段似乎对我都不起作用。这是我在这方面的尝试:
# The following command sort of worked:
# ~/bin/wikitool.pl -action attach_file -url $MYURL
# IT attached something but the file was empty
sub attach_file {
my $confluence = XMLRPC::Lite->proxy($
我想我可能在我的代码中遇到了goto的一个很好的使用。从我开始用C语言编程时,我就开始意识到goto就像召唤魔鬼一样,应该不惜一切代价避免使用goto。这是代码
/*
Attempts to get the physical address from a virtual one by
1. Consulting the TLB
2. Consulting the PageTable
3. If both fail, request data be read into memory
Returns the address of the request
我正在尝试实现LRU算法,但是我真的不太确定如何将FIFO更改为LRU,以及如何在
//The declared parameters are as follows:
pt_entry pte[MAX_PAGE]; /* page table */
int mem_size; /* physical memory size in page frames */
list free_list_head; /* free list */

我有一个应用程序运行良好,在一个普通系统上有4GB RAM,但是当我将系统RAM设置为12 GB时,系统崩溃,我需要重新启动应用程序。
是否必须手动设置内存更改的内核参数?

我正在构建一个Flex应用程序,但在检测变量是否已初始化时遇到了问题。观察这个简化的代码示例:

private function constructMenu(e:ResultEvent):void {
if (this.pageObject != null) {
Oops之后的错误代码会给出有关arm ex中的恐慌的信息。在这种情况下,Oops: 17 [#1] PREEMPT SMP 17给出了什么信息。在x86中它代表-
