Hi, Juan, Aron and all I fix Juan's http://hg.et.redhat.com/kernel/linux-2.6-xen-fedora to build on ia64. But I have not booted linux kernel (not xen), and there are many compile warnings. I'm fixing the tree now. I used the attach config. Please check them. My fix patcheds are the blew. Please comments. 1. build_ia64_add_files.patch simple import gate.S, gate.ld.S, patch.c into arch/ia64/kernel (these are from linux-2.6.18-rc2) 2. build_ia64.patch some fix (resend_irq, ioremap, and so on) Signed-off-by: Akio Takebe <takebe_akio@xxxxxxxxxxxxxx> Best Regards, Akio Takebe >On Sat, 2006-07-22 at 09:31 -0400, Aron Griffis wrote: >> Hi guys, >> >> There are four ways you could be a big help to the xen-ia64 effort. >> I have mentioned these in the past but never pulled them together into >> a single request. > >Sorry for getting so long in answering you, but A PAE bug and getting >linux-2.6-xen working on 2.6.18-rc2 have required all my attention :( > >> 1.
