[okl4-developer] Memory ballooning

[cheng...@gmail.com]

Hi，I‘m new to OKL4 and recently I've been reading the references and source code (okl4 3.0).

My question is about the memory management in okl4 3.0.  I get limited info in this area (reference doesn't tell much ). Has it realized memory ballooning (like Xen, KVM, etc.) or some sort of thing?

 

PS:  I'll be appreciated if someone can provide me details about its memory management.

Hi Cheng,

The L4 kernel is certainly capable of supporting a variety of different memory management techniques, including ballooning. OKL4 kernels are however a microkernel like, so they do not implement any specific policy. This means that ballooning and other techniques can be implemented using higher level software on top of the kernel API.

Please note, the OKL4 3.0 code base does not include any examples of these types of memory management. If you have any specific requirements, please contact us.

Regards,
Carl

Thanks, Carl.

And one more question: OKL4 doesn't support hardware-assisted virtualization, right? And is there a schedule or a plan? Why or why not? (Sorry for actually three questions.)
