Using new vm_page_alloc_contig() may be a better option here.
Can't help with patch, stuck with pre Nov 15 CURRENT myself.

vm_page_alloc_contig() should be used instead.
My take on the patch:
http://people.freebsd.org/~avg/vbox-10.patch
This is for head only, no check for FreeBSD version.
Actually, I did the same thing last night:
http://people.freebsd.org/~jkim/patch-src-VBox-Runtime-r0drv-freebs
d-memobj-r0drv-freebsd.c
This is a drop-in replacement for the patch. The only practical
difference I see from yours is I used VM_ALLOC_INTERRUPT instead of
VM_ALLOC_NORMAL. I believe this function may be used in interrupt
context. FYI, I tried FreeBSD 9 and Fedora 10 without problem.
BTW, I needed another patch to build virtual-ose-kmod on head:
http://people.freebsd.org/~jkim/patch-src-VBox-HostDrivers-Support-freebsd-SUPDrv-freebsd.c
FYI...
Yep, me too, obviously :-)
Thank you for the complete vm_page_alloc_contig patch!
Thanks for the patch. I'll give it a try.
OTOH yesterday I was trying to use vm_page_alloc_contig and trying to
understand the allocation classes. I was able to panic the system or in
the best case VBoxHeadless was getting a sig11.
I was planning to ask the mailing list about them, because even I
read vm-design article in the doc section there are things I don't yet
understand:
First question is, if you set NULL for the vm_object_t (and then
VM_ALLOC_NOOBJ must be given or the kernel will panic with INVARIANTS
set) how this memory is assigned to the VirtualBox process logical space?
Second set of related questions are: why should the pages be wired?
and why should the VM_ALLOC_INTERRUPT alloc class be given?
Third question is: I see in the patch that
rtR0MemObjFreeBSDPhysPageInit is not called if the veersion is less that
1000000, is this because vm_phys_alloc_contig doesn't set the flags on
the pages and vm_page_alloc_contig does?
Thanks,
Gus
