[Xen-ia64-devel] [PATCH 00/50] ia64/xen take 3: ia64/xen domU paravirtua
Hi. This patchset implements xen/ia64 domU support.
Qing He and Eddie Dong also has been woring on pv_ops so that
I want to discuss before going further and avoid duplicated work.
I suppose that Eddie will also post his own patch. So reviewing both
patches, we can reach to better pv_ops interface.
- I didn't changed the ia64 intrinsic paravirtulization abi from
the last post. Presumably it would be better to discuss with
the Eddie's patch.
- I implemented The basic portion of domU pv_ops.
They may need the interface refinement. Probably Eddie has
his own opinion.
- This time I dropped the patches which hasn't been pv_ops'fied yet
because they aren't changed from the last post.
You can also get the full source from
http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
branch: xen-ia64-2008mar06
The patchset are organized as follows
- xen arch portability.
Generalizes x86 xen patches for ia64 support.
- some preliminary patches.
Make kernel paravirtualization friendly.
- introduce pv_ops and the definitions for native.
- basic helper functions for xen ia64 support.
- introduce the pv_ops instance for xen/ia64.
TODO:
- discuss and define intrinsic paravirtualization abi.
- discuss pv_ops.
- more pv_ops for domU
- mca/sal call
- timer
- gate page
- fsys
- support save/restore/live migration
- more clean ups
- remove unnecessary if (is_running_on_xen()).
- Free xen_ivt areas somehow. No waste kernel space
From Keith Owens idea.
Probably after defining ABI because this is just optimization.
- dom0
consider after finishing domU/ia64 merge.
Changes from take 2:
- many clean ups following to comments.
- clean up:assembly instruction macro.
- introduced pv_ops: pv_info, pv_init_ops, pv_iosapic_ops, pv_irq_ops.
Changes from take 1:
Single IVT source code. compile multitimes using assembler macros.
thanks,
