umm...sweety? Hybrid kernels ARE microkernels...

>A hybrid kernel is an operating system kernel architecture that attempts to combine aspects and benefits of microkernel and monolithic kernel architectures used in computer operating systems.

>>1011423

"aspects and benefits" is a bit of a disingenuous description. All "hybrid" kernels are technically microkernels but what makes them "hybrid" is how they are abstracted from userspace

>>1011424

>The "hybrid" category is controversial, due to the similarity of hybrid kernels and ordinary monolithic kernels

If anything they are technically monolithic kernels you fuckwit

>>1011427

They're microkernels in a monolithic configuration. ntoskrnl.exe and mach are not fully monolithic either

Also, most hybrid kernels are nowadays monolithic kernels with single elements being moved to userspace, while most drivers stay in kernel.

>>1011431

Its about interface flexibility I think. With a hybrid you can move more things to and from kernel and userspace vs a purely monolithic kernel where it may not be as simple. It seems to compromise and benefit from both paradigms
