I'd like to get the Xenlinux/ia64 changes and tree up from 2.6.12
to 2.6.15 and would like timing/planning guidance on how best
to do this. There are a handful of changed files and a couple
of handfuls of xen files. There is also some buildtime scripting
to move files around that Xenlinux/x86 uses and Xenlinux/ia64 doesn't,
or drop files from driver Makefiles (e.g. netback) that aren't yet
working on Xenlinux/ia64 (c.f. sparse/arch/ia64/xen-mkbuildtree-pre)
Questions:
1) What is the difference between linux-2.6-merge.hg and
linux-2.6-xen.hg and which should I be using?
2) Should I merge into one of the linux-2.6-*.hg trees
or wait until the linux-2.6-*.hg tree gets pulled into
xen-unstable.hg/linux-2.6-sparse?
3) If merging into linux-2.6-*.hg, I'm thinking rather than
send a big patch that will require someone to do a bunch
of "hg add"s, I would just provide an ftp'able tgz file
of the updated hg tree that could be ftp'd and merged.
Will that work, or is there a better way?
Thanks,
Dan
P.S. In the spirit of Christian's recent list, here's the
list of all the files that change for Xenlinux/ia64. Note
that as we switch to VP/P2M, this list will (sadly) grow.
======================
Xen/ia64 changed files
======================
Xen/ia64 config:
Files: arch/ia64/Kconfig
Files: arch/ia64/Makefile
Descr: enable Xen hypervisor support
ia64 assembly routine hooks:
Files: arch/ia64/kernel/entry.S
Files: arch/ia64/kernel/pal.S
Descr: add indirection to allow for hooks in assembly routines with
privilege-sensitive instructions and performance critical
privileged
instructions
ia64 startup
Files: arch/ia64/kernel/head.S
Files: arch/ia64/kernel/setup.c
Descr: early hooks for Xen-specific setup
ia64 privileged instruction macro hooks:
Files: include/asm-ia64/{gcc,intel}_intrin.h
include/asm-ia64/pal.h
include/asm-ia64/processor.h
Descr:
ia64 "flags" simplification
Files: include/asm-ia64/system.h
include/asm-ia64/processor.h
Descr: flags need only use psr.i bit not entire psr; saving/restoring
entire psr is very expensive to paravirtualize
