Try this.
It is Richard Henderson's WIP patch for dynamic DMA I've hacked for what
Linus finally accepted into 2.3.41 and hopefully with all the
NEW_PCI_DMA_MAP stuff protected by an ifdef of the same name, so if I
haven't forgotten anything (don't have an Alpha nor cross-compiler set up),
it should be working for you if you don't have more than 4G (or what was the
limit on Alpha) of physical memory.
Please tell me if the patch does not compile.
Once this Alpha code is finished and NEW_PCI_DMA_MAP enabled and working,
this will remove physical memory limits on Alpha (like it did on
UltraSPARC where we don't pose any physical RAM limits in 2.3.42 any more,
so if you want on sparc64 128GB of RAM, just prepare enough bucks for a big
machine) without ugly hacks like bigmem/Alpha.
All drivers you use on such system have to be converted to the new DMA
mapping API though (in vger CVS we have converted all drivers which are
available as config options for sparc64 and will be working on merging it to
Linus' tree through maintainers).
Cheers,
Jakub
