Re: Proposed new kernel noncaching memory allocator for the 405gp

Frank,

Yes, but these allocate on a page boundry and I was thinking of something a
little more granular.

Any objections?

for devices that are not pci based.  We are still working on getting a

cache coherency problems.

Dan Malek has provided the functions consistent_alloc(), consistent_free(),
and consistent_sync() for uses other than PCI.  They are in linuxppc_2_5
rev 1.446 and later (I'm not sure if they are in any earlier version).
They are also in my active development kernel, but not yet in any kernel
that I have put on my ftp site.
