I still don't know what's the best way to handle that one... the bug is in X and I don't see a way to work around it without removing support for legacy memory access from the kernel :-( Or doing it in a way that doesn't allow userspace to differenciate between the kernel not supporting it vs. the HW not supporting it, causing X to fallback to even more broken crap. I'll try to find out the extent of the X problem and whether that's fixable in a way that can hit distros. > > Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12608 > Subject : 2.6.29-rc powerpc G5 Xorg legacy_mem regression > Submitter : Hugh Dickins > Date : 2009-01-21 21:12 (15 days old) > First-Bad-Commit: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d3a54014e2a94bd37b7dee5e76e03f7bc4fab49a > References : http://marc.info/?l=linux-kernel&m=123257250431870&w=4 > Handled-By : Benjamin Herrenschmidt >
