The Linux kernel is a monolithic kernel that's constantly growing; it had 20 million lines of code in 2018. From a foundational level, it's layered into a variety of subsystems. These main groups include a system call interface, process management, network stack, memory management, virtual f...
KeEnterCriticalRegion Temporarily disables the delivery of normal kernel APCs while a highest-level driver is running in the context of the user-mode thread that requested the current I/O operation. Special kernel-mode APCs are still delivered. KeLeaveCriticalRegion Reenables, as soon as possible...
c.thd->mdl_context.has_locks(MDL_key::USER_LEVEL_LOCK) || c.thd->mdl_context.has_locks(MDL_key::LOCKING_SERVICE))); } 被放入高优先级队列的事件可以优先被 worker 线程处理。 只有当高优先级队列为空,并且当前线程组不繁忙的时候才处理低优先级队列中的事件。线程组繁忙(too_many_busy_threads)...
While Tilck uses internally the concept of thread, multi-threading is not currently exposed to userspace (kernel threads exist, of course). Bothfork()andvfork()are properly implemented and copy-on-write is used for fork-ed processes. Thewaitpid()syscall is fully implemented (which implies proc...
The VMkernel networking layer provides connectivity to hosts and handles standard system traffic ofvSphere vMotion, IP storage, fault tolerance, etc. TheTCP/IPstacks at the VMkernel level include: Default TCP/IP stack:It provides networking support for managing traffic between the vCenter Server an...
When multiple threads write to the same location, only one thread succeeds in the write; which thread that succeeds is undefined. Detailed memory metrics are collected by the Memory Workload Analysis section. Caches All GPU units communicate to main memory through the Level 2 cache, also known ...

Microsoft Windows Debugger (WinDbg) is a powerful Windows-based debugging tool that you can use to perform user-mode and kernel-mode debugging. WinDbg provides source-level debugging for the Windows kernel, kernel-mode drivers, and system services, as well as user-mode applications and drivers....
The design of a kernel-level thread package for dynamic, hard real-time environments is presented. A highly integrated design is used to ensure predictability. A system description language and real-time programming language are used to specify key properties of threads and thread groups. For a ...
