[pkg-nvidia-devel] Bug#500175: nvidia-kernel-source: Please support compilation against non-paravirt ops style Xen kernels

[Ian Campbell]

Package: nvidia-kernel-source
Version: 173.14.09-5.0.hellion1
Severity: wishlist
Tags: patch

The nvidia kernel source is currently patched to remove the Xen special casing
in order to allow it to build and run against a kernel which has both
CONFIG_PARAVIRT=y and CONFIG_XEN=y but is running natively. (I think this was
due to #481485, #482305, #496173 etc)

The kernel team are proposing to enable a patch to support the old-style (i.e.
non-CONFIG_PARAVIRT) CONFIG_XEN in order to regain domain0 and 64 bit support
for Lenny. See http://lists.debian.org/debian-kernel/2008/09/msg00742.html and
http://lists.alioth.debian.org/pipermail/pkg-xen-devel/2008-September/002044.html
This will unfortunately break the compilation of the current nvidia kernel
source against these kernels.

I have updated the xen.patch to support both CONFIG_PARAVIRT-Xen (running Xen)
and Legacy-Xen. I have tested with 2.6.26-1-amd64 (CONFIG_PARAVIRT running on
native, pkg version 2.6.26-5) as well as 2.6.26-1-xen-amd64 (Legacy-Xen,
running as a Xen domain 0, pkg version 2.6.26-7~snapshot.12252) and
2.6.18.8-xen (Legacy-Xen, running as a Xen domain 0, my own build). I also
build tested against 2.6.26-1-686 but can't reboot that machine at the moment
since it's running a long running test.

I've filed this bug as a wishlist preemptively before the kernel is uploaded,
once the kernel goes in presumably the priority will increase.
