[PATCH 00/30] ia64/xen domU take 10 | |
| [Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] | |
This patchset is ia64/xen domU patch take 10 which is rebased
to 2.6.27-rc4.
This patchset implements ia64/xen domU support based on ia64/pv_ops
frame work which was sent as another patchest.
This patchset does the followings.
- Some preparation work. Mainly importing header files to define
related structures.
- Then, define functions related to hypercall which is the way to
communicate with Xen hypervisor.
- Add some helper functions which is necessary to utilize
xen arch generic portion.
- Next implements the xen instance of pv_ops introducing
pv_info, pv_init_ops, pv_cpu_ops and its assembler counter part,
pv_iosapic_ops, pv_irq_ops and, pv_time_ops step by step.
- Introduce xen machine vector to describe xen platform.
By using machine vector, xen domU implementation can be simplified.
- Lastly update Kconfig to allow paravirtualization support and
xen domU support to compile.
To compile, the changesets in x86/xen branch are also needed.
I expected the necessary patches will be merged soon.
For convenience the working full source is available from

branch: ia64-pv-ops-2008aug26-xen-ia64
For the status of this patch series
http://wiki.xensource.com/xenwiki/XenIA64/UpstreamMerge
At this phase, we don't address the following issues.
Those will be addressed after the first merge.
- optimization by binary patch
In fact, we had the patch to do that, but we intentionally dropped
for patch size/readability/cleanness.
- freeing the unused pages, i.e. pages for unused ivt.S.
- complete save/restore support
- ar.itc paravirtualization which is necessary for save/restore support
Changes from take 9:
- rebased to 2.6.27-rc4
- caught up moving header files.
- caught up the x86 xen changes (mainly xen mode predicate)
- enhanced pv checker to detect inappropriate register usage.
- typo
Changes from take 8:
- rebased to 2.6.26
- updated pvclock-abi.h
Changes from take 7:
- various typos
- clean up sync_bitops.h
- style fix on include/asm-ia64/xen/interface.h
- reserve the "break" numbers in include/asm-ia64/break.h
- xencomm clean up
- dropped NET_SKB_PAD patch. It was a bug in xen-netfront.c.
- CONFIG_IA64_XEN -> CONFIG_IA64_XEN_GUEST
- catch up for x86 pvclock-abi.h
- work around for IPI with IA64_TIME_VECTOR
- add pv checker
Changes from take 6:
- rebased to linux ia64 test tree
- xen bsw_1 simplification.
- add documentation. Documentation/ia64/xen.txt
- preliminary support for save/restore.
- network fix. NET_SKB_PAD.
Changes from take 5:
- rebased to Linux 2.6.26-rc3
- fix ivt.S paravirtualization.
One instruction was wrongly paravirtualized.
It wasn't revealed with Xen HVM domain so far, but with real hw
- multi entry point support.
- revised changelog to add CCs.
Changes from take 4:
- fix synch bit ops definitions to prevent accidental namespace clashes.
- rebased and fixed breakages due to the upstream change.
Changes from take 3:
- split the patch set into pv_op part and xen domU part.
- many clean ups.
- introduced pv_ops: pv_cpu_ops and pv_time_ops.
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,
