User space and kernel space information

Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data...

vector representations via a user-specified feature map: in contrast, kernel methods require only a user-specified kernel, i.e., a similarity function...

services in a hybrid kernel are still in kernel space. There are none of the reliability benefits of having services in user space, as with a microkernel...

only a single address space, there is no need for repeated privilege transitions to move data between user space and kernel space. Therefore, a library...

The Linux kernel provides multiple interfaces to user-space and kernel-mode code that are used for varying purposes and that have varying properties by...
