Fedora xen - Jul 2006 - RE: [PATCH 0 of 5] fix linux-2.6-xen-fedora on ia64

Hi Aron,
	Could you share me the current status for fedora-xen-ia64? Through your mails,
I see we should focus our efforts on linux-2.6-xen-fedora. But when I applied
the patch 199684 on it, conflicts occurs. Do you have any suggestion for
contributing to Fedora ?
Thanks & Best Regards

Hi, Xiantao

BZ''s patch is old. 
Today 139 cset is added to linux-2.6-xen-fedora tree.
So I think we should use Aron''s patches.

Best Regards,

Akio Takebe

Xiantao and Akio,

Sorry that I''m not very good sharing status.  Here is an update to
hopefully put us on the same page again.

First, a review of the repos available, since this is always a point
of confusion:

    http://hg.et.redhat.com/kernel/linux-2.6-xen-fedora
    - This is Juan''s tree from which he generates linux-2.6-xen.patch
      for the Fedora kernel rpm.  Juan creates this tree as
      a combination of pulls from:
	    http://kernel.org/hg/linux-2.6
		- automatic mirror of Linus'' git tree
	    http://xenbits.xensource.com/linux-2.6-xen.hg
		- sparse tree patches applied to 2.6.16 kernel,
		  maintained mostly-daily by Christian
	    http://xenbits.xensource.com/ext/linux-2.6.tip-xen.hg
		- sparse tree patches merged to 2.6.18 kernel,
		  maintained sporadically by Chris Wright
	    PLUS Juan''s own patches to make it all work together.

    http://free.linux.hp.com/~agriffis/linux-2.6-xen-fedora-ia64
    - This pulls from linux-2.6-xen-fedora, but also includes our
      patches to fix building on ia64.

    http://free.linux.hp.com/~agriffis/kernel-cvs
    - This is a mercurial mirror of the Fedora kernel cvs (see
      http://people.redhat.com/davej), updated numerous times per
      day by me.

    http://free.linux.hp.com/~agriffis/kernel-cvs-ia64
    - This pulls from kernel-cvs, but also includes spec-file changes
      necessary to build and test on ia64.  In particular, this
      includes linux-2.6-xen-ia64.patch which is our current
      collection of updates to Juan''s tree to support ia64.

Second, what works, what doesn''t:

    kernel-cvs-ia64 builds on ia64, both with and without CONFIG_XEN.
    The normal kernel boots, the xen kernel doesn''t yet.

    Considering that everything builds at this point, I''ve requested
    for Juan to update his repo *and* update the spec to enable
    building on ia64.  This is driven by wanting to land in FC6 T2.
    We still need to make the xen kernel boot though :-)

Third, how to contribute:

    If you prefer to work with raw xen and kernel sources instead of
    the rpm, do this first to get the kernel configs:
	hg clone http://free.linux.hp.com/~agriffis/kernel-cvs-ia64
	cd kernel-cvs-ia64/devel
	make configs

    That generates these files, which you can use in a kernel tree
    with oldconfig:
	kernel-2.6.17-ia64.config
	kernel-2.6.17-ia64-xen.config

    Next get the kernel to work on:
	hg clone http://free.linux.hp.com/~agriffis/linux-2.6-xen-fedora-ia64

    Send your patches to me and cc fedora-xen and xen-ia64-devel.
    To know what hypervisor changeset to use, check the spec file:
	cd kernel-cvs-ia64/devel
	grep -m1 xen_hv_cset kernel-2.6.spec

Thanks,
Aron

Thanks, I just put an updated patch in BZ 199684, but best approach is
to work from the mercurial trees I described in my previous email.

Actually this last two are also full trees, not sparse trees.  It is
way, way easier to work against a full tree that against a sparse tree.

Wow, you are fast catching my changes :)  That variable was called
xen_cset until yesterday :)

Later, Juan.

Hi, Aron

Thank you for your good explanation.
I have one question.

Which is this cset xen-ustable''s cset or xen-ia64-unstable''s
cset?

Best Regards,

Akio Takebe

xen-unstable (only for the HV).

As far as I am concerned xen-ia64-unstable don''t exist :)

Patchs arrive to me though
	xen-unstable -> linux-2.6-xen
	(prefered method for core things)

Somebody send me a mail or ask me to hg pull for some tree
	especially for things that don''t make sense to be on 
	xen-unstable because they are based in a quite old kernel.

Later, Juan.

That''s what I meant, I just said it unclearly :-)

Thanks,
