How do you ensure that circular references are correctly cleaned up at domain destruction time? (i.e., A references B and B references A). We have special destructore code to clean up all root pagetable references, but the code isn't there for lower levels. -- Keir On 15/2/07 09:41, "Jan Beulich" <jbeulich@xxxxxxxxxx> wrote: > While full linear page table support makes little sense (and would be more > complicated to implement), partial linear page table support is almost > identical > to that in non-PAE, and is used (at least) by NetWare. > > Of course, the question here is whether this shouldn't be generalized - all > validated page tables (except for top level PAE) could be allowed to be > installed > at lower levels using the same scheme. > > Signed-off-by: Jan Beulich <jbeulich@xxxxxxxxxx> _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
