It would be better if you'd merge this and next patch into one and call
it "Move out IOMMU detection into a separate function", or something
similar. The reason is that at no point the code is duplicated, where as
with this approach it is (even if for a short time).

This does not belong here. The proper order is to prepare everything and
introduce new feature after that. Imagine that virHostHasIOMMU() will be
used later, in a commit that fixes a bug. Now, downstream maintainers
would probably want to backport that particular fix and since it uses
virHostHasIOMMU() they will also backport this commit. But at the same
time they would be backporting a new feature which is something you
shouldn't do (the whole point of backporting commits is to stabilize
code base and introducing new features goes against that).

Since this is copied from qemuHostdevHostSupportsPassthroughVFIO() the
correct patch would be where you're moving this part out of there into here.

This patch misses libvirt_private.syms adjustment. Again, long story
short, one patch needs to contain one semantic change. And looking into
next patch (where you have the syms change) does not follow the rule.

As I say in review to previous patch, this should go into 1/4.

This should be merged into 1/4. What seems to be correct patch
ordering/content:
1) move out parts of qemuHostdevHostSupportsPassthroughVFIO() into a
separate function (be it virHostHasIOMMU()), expose it in
libvirt_private.syms and corresponding header file.
2) Introduce caps->iommu (which is basically patch 3/4) witch all
changes you need (libvirt_private.syms change for
virCapabilitiesHostInitIOMMU(), adding bool to struct _virCapsHost, etc.)
3) document the feature in news.xml.

All patches are missing S-o-B line. I have a special alias for that for
instance. This is in my ~/.gitconfig:
[alias]
cs = commit --signoff
so then I'm committing patches as:
libvirt.git$ git cs -a
S-o-B line is now required. And even for projects where it isn't just
yet it doesn't hurt. Therefore it makes sense to have it as default.
