For this reason, the code executed in the kernel space is considered a code that is executed in a privileged mode.As an example, let's consider the GPIO subsystem we already saw in the previous chapter where we talked about U-Boot. In Linux, we can manage these devices easily using ...
name:gpio-keys-polled(this name is obtained usingioctlcall with requestEVIOCGNAME). Then, it will start a thread (using pthread) to poll this device. The power button is a separate device from all other buttons, and the reset button (under the power button) is hardwired to reset the ...
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: ...
Open a module loading driver and use an ioctl to tell that driver the size of the module. The module loading driver calls kmem_alloc() in the kernel for text, data and bss segments and returns the addresses returned by kmem_alloc() in the result structure of the ioctl....
a newIOCTLcommand,MP_SEND_SCSI_CMD, is added and is referenced through the existingscsi_vhci IOCTLinterface. An extension is introduced to the multipath management library (MP-API) which provides access to this newIOCTLcommand. This enables network administrators to run diagnostic commands through ...

There is also support for debugging and deployment of drivers to an ARM64 target machine from both ARM64 and x64 host machines. The process of installing WDK/EWDK on ARM64 machines will automatically identify and install all the necessary dependencies including build tools, binaries and libraries...
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 ...
