对于这个问题的一个答案是,首先我们会有user/kernel边界,在上面是应用程序,在下面是运行在kernel mode的程序。 其中一个选项是让整个操作系统代码都运行在kernel mode。大多数的Unix操作系统实现都运行在kernel mode。比如,XV6中,所有的操作系统服务都在kernel mode中,这种形式被称为Monolithic Kernel Design(宏内核)。
By this way, it could testifywhether the microkernel systems could be more flexible, portable and secure than monolithicoperating systems. Unixbench could give sufficient statistics on different capacities of MINIX3 andLinux, such as system call overhead, pipe throughput, arithmetic test and so on. ...
aMicro-kernels to date have not provided compelling advantages over the conventional monolithic operating system kernel for several reasons. 微仁为几个原因迄今未提供強制好处胜过常规整体操作系统的仁。[translate]
the hardware it runs in. The other components of the OS interact with the microkernel in a message-based relationship and do not have to be rewritten if the OS is ported to new hardware. Only the hardware-dependent microkernel must be reprogrammed. Contrast withmonolithic kernel. Seekernel. ...
Take the case of an AI personal assistant with various services: location,calendar,email,banking,shopping,travel,weather, etc… If you were to build this as a monolithic agent, it would be directly bound to its tooling. Namely, all provided functions and plugins would need to fit in that ag...
Figure 6.2.Microservices and containers. Monolithic style– a monolithic application built as a single unit. For example, enterprise applications are often built in three main parts: a client-side user interface (consisting of HTML pages and JavaScript running in a browser on the user's machine)...
The core problem of the monolithic architecture is that the conflict domain is too large, including the shared code base. It is particularly prone to conflicts in the R&D process; the boundaries and the scale of the modules are not clear, so that the efficiency of the team will also be re...

On Intel, when virtualization is enabled, the CPU is divided into the host and the guest. The hypervisor runs in the host, while the operating system runs in the guest. Both the host and the guest have a Ring 0 and Ring 3 privilege level. Monolithic hypervisors like Xen and KVM run ...
Reduced costly downtime per device with live patching of the kernel, allowing security patches to be applied as soon as available without waiting for a maintenance window and without stopping the running kernel. At the edge, this mitigates the high security risk from thousands of devices that hav...
