[K42-discussion] Large page pinning on K42

[YipKei Kwok]

Hi,

I have several questions regarding paging for large pages on the K42
operating systems.

1. By default, once a large page is allocated, is it pinned in the
memory so it will not be paged out? If no, is there any mechanism
which could enforce such a restriction?

2. Previous research has been done on K42 running on the PowerPC 970FX
(G5) processor. Was paging out of large pages restricted? If yes, is
the restriction imposed by the operating system or the processor?

Thank you very much!

Regards,
Yipkei
