PC机上引导程序一般由BIOS开始执行,然后读取硬盘中位于MBR(Main Boot Record,主引导记录)中的Bootloader(例如LILO或GRUB),并进一步引导操作系统的启动。 嵌入式系统中通常没有像BIOS那样的固件程序,因此整个系统的加载启动就完全由bootloader来完成,它主要的功能是加载与引导内核映像。 一个嵌入式的存储设备通过通常包括四...

然后在complete_signal()里因为SIGTERM是sig_fatal信号,所以会遍历这个进程里的所有线程,将每个线程的的pending信号集上置上SIGKILL,并且将这个进程的task_struct的signal_struct的flag值设置为SIGNAL_GROUP_EXIT 然后是这个进程里的每个线程均去处理这个SIGKILL信号,在get_signal()里,因为进程的task_struct.signal_struct...
The UNEXPECTED_KERNEL_MODE_TRAP bug check has a value of 0x0000007F. This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap. This trap could be either of the following types: Abound trap, which is a trap the kernel isn't permitted to catc...
Before using BCDEdit to change boot information you may need to temporarily suspend Windows security features such as BitLocker and Secure Boot on the test PC. Re-enable these security features when testing is complete and appropriately manage the test PC, when the security features are disabled. ...
其函数主要作用为指示调用方一个IRP请求已经完成。为了确保向驱动程序发出的IRP请求成功完成,需要向驱动程序传递一个有效的IO代码——这使得IofCompleteRequest成为一个识别驱动程序接受的IO代码的有效途径。 查看其调用 这里我们发现IrpDeviceIoCtlHandler函数,因为其相当于是一个客户端IRP请求的管理器。
The KERNEL_LOCK_ENTRY_LEAKED_ON_THREAD_TERMINATION bug check has a value of 0x00000153. This indicates that a thread was terminated before it had freed all its AutoBoost lock entries.
The UNEXPECTED_KERNEL_MODE_TRAP_M bug check has a value of 0x1000007F. This indicates that a trap was generated by the Intel CPU and the kernel failed to catch this trap. Bug check 0x1000007F has the same meaning and parameters asbug check 0x7F(UNEXPECTED_KERNEL_MODE_TRAP). ...
