Major new WinDbg features are listed here. For full details on the updates to WinDbg seeWinDbg Release Notes. For general information about the debugging tools, seeWhat is WinDbg?. Live Linux debugging You can now live debug a Linux process. For more information, see these articles: ...
The following message is output Raw kernel: involflt[process_get_monitoring_stats_ioctl:2859 (ERR)]: Failed to get target context for uuid /dev/sda Environment Red Hat Enterprise Linux 6 3rd-party kernel module:involflt Subscriber exclusive content ...
Using SPIDEV, this is accomplished by stacking up two SPI driver messages and sending them down using ioctl() calls. The first one sets "cs_change=0" so the CS wont change between #2 and #3 above. That's what's not working. Instead, the CS toggles and the FPGA starts a whole new...
A device driver is a special code that interfaces a physical device into the system and exports it to the user-space processes using a well-defined API. In a UNIX-like OS, where everything is a file, the physical device is represented as a file. Then, the device driver implements all ...
在Unix/Linux系统中,需要执行fork系统调用后exec系统调用来启动一个新进程。fork调用会克隆当前执行的进程,而exec调用则会在调用进程上覆盖一个基于不同可执行文件的新进程。 2.7 What is the purpose of system programs? 答: 为程序开发和运行提供了方便的环境 ...
1. Displaying all Network Interfaces in Linux Here, one distinguishing feature betweenipandifconfigis that whereas ifconfig only shows enabled interfaces, ip shows all the interfaces whether enabled or disabled. ifconfig Command $ ifconfig

■ /usr/sbin/mpathadm CLI ■ /lib/libMPAPI.so common library ■ /lib/libmpscsi_vhci.so plug-in for the scsi_vhci driver The following areas have been extended to support the SNIA MP API feature: ■ MDI ■ SCSA ■ libdevinfo ■ scsi_vhci IOCTL With this feature, the administrators ca...
The MPxIO path steering feature includes a mechanism for issuing SCSI commands to an MPxIO LU to be delivered down a specified path to the LU. In order to provide this functionality, a newIOCTLcommand,MP_SEND_SCSI_CMD, is added and is referenced through the existingscsi_vhci IOCTLinterface....
在QEMU-KVM中,KVM运行在内核空间,QEMU运行在用户空间,实际模拟创建、管理各种虚拟硬件,QEMU将KVM整合了进来,通过/ioctl 调用 /dev/kvm,从而将CPU指令的部分交给内核模块来做,KVM实现了CPU和内存的虚拟化,但KVM不能虚拟其他硬件设备,因此qemu还有模拟IO设备(磁盘,网卡,显卡等)的作用,KVM加上QEMU后就是完整意义上的...
