New subject: [libvirt] [PATCH v3 1/8] conf: use struct instead of int for each slot in virDomainPCIAddressBus
When keeping track of which functions of which slots are allocated, we
will need to have more information than just the current bitmap with a
bit for each function that is currently stored for each slot in a
virDomainPCIAddressBus. To prepare for adding more per-slot info, this
patch changes "int slots" into "virDomainPCIAddressSlot slot", which
currently has a single member named "functions" that serves the same
purpose previously served directly by "slots".

New subject: [libvirt] [PATCH v3 2/8] conf: eliminate concept of "reserveEntireSlot"
setting reserveEntireSlot really accomplishes nothing - instead of
going to the trouble of computing the value for reserveEntireSlot and
then possibly setting *all* functions of the slot as in-use, we can
just set the in-use bit only for the specific function being used by a
device. Later we will know from the context (the PCI connect flags,
and whether we are reserving a specific address or asking for "the
next available") whether or not it is okay to allocate other functions
on the same slot.
Although it's not used yet, we allow specifying "-1" for the function
number when looking for the "next available slot" - this is going to
end up meaning "return the lowest avaialable function in the slot, but
since we currently only provide a function from an otherwise unused
slot, "-1" ends up meaning "0".

New subject: [libvirt] [PATCH v3 3/8] conf: eliminate repetitive code in virDomainPCIAddressGetNextSlot()
virDomainPCIAddressGetNextSlot() starts searching from the last
allocated address and goes to the end of all the buses, then goes back
to the first bus and searchs from there up to the starting point (in
case any address has been freed since the last time an address was
allocated. The loops for these two are almost, but not exactly, the
same, so they have remained as separate loops with the same code
inside the loop. To lessen maintenance headaches, the identical code
has been moved out into the function
virDomainPCIAddressFindUnusedFunctionOnBus(), which is called in place
of the loop contents.

Having some documentation for the function, especially
what parts of @searchAddr are inspected and updated, and
how @function is used - not at all right now, but that's
going to change later in the series - would be great.
Incidentally, and not relevant to this series, passing
around partially filled-in virPCIDeviceAddress instances
*and* some of the same data on the side sucks big time.
I wonder if the whole thing could be improved by changing
the struct members to to signed and having
#define VIR_PCI_DEVICE_ADDRESS_UNDEFINED -1
or leave them as it is and use
#define VIR_PCI_DEVICE_ADDRESS_UNDEFINED UINT_MAX
instead. Either way, we'd have a way to tell whether each
of the components has been initialized or is in need of a
value without having to pass data out-of-band.

There is a very slight time advantage to beginning the search for the
next unused PCI address at the slot *after* the previous find (which
is now used), but if we do that, we will miss allocating the other
functions of the same slot (when we implement a
VIR_PCI_CONNECT_AGGREGATE_SLOT flag to support that).

New subject: [libvirt] [PATCH v3 5/8] conf: new function virDomainPCIAddressIsMulti()
This function iterates through all the devices in a domain to
determine if the address it has been given is part of a "multifunction
device" (i.e. multiple devices connected to different functions of the
same slot).
This implementation may seem a bit inefficient because it has to
iterate through all the devices for each device that needs checking,
but this really is our only option since the address allocation set
isn't always available (and maybe not even exist at the time it's
needed).

New subject: [libvirt] [PATCH v3 6/8] qemu: use virDomainPCIAddressIsMulti() to determine multifunction setting
If the multifunction attribute isn't set in the config for the device
at function 0 of a slot used for multifunction, it would previously
have been an error. This patch will instead automatically correct the
omission (but only if it hasn't been set at all - if someone
explicitly has "multifunction='off'" on function 0, or
"multifunction='on'" when function != 0, we have to assume they have a
reason for that).
This effectively obsoletes the requirement of specifying
multifunction='on' in the config, although you're still free to do
so. Note that if you migrate a domain that needs an implied
"multifunction='on'" back to any older libvirt that doesn't have
it,
the migration will fail. (Note that this would only be an issue with a
domain config that was *created* on a newer libvirt; any config
created on an older libvirt and then later migrated to a newer libvirt
would necessarily have multifunction explicitly set in the config, and
that will not be lost during migration).

We need to be able to migrate new -> old, as apps like oVirt and
OpenStack can be running a mix of old & new libvirt & QEMU versions
and may migrate between the two in both directions.
As far as I'm concerned, the only reason you would want to do
that is because you are upgrading your hypervisor pool and,
at some point during the process, you realize there are issues
with the upgrade and need to roll back. As you mention, that
use case would work just fine because the guests have been
defined using an older libvirt versions.
If you have 1000's of hypervisor nodes deployed, upgrading all
of them may take a non-trivial amount of time (days, or even
weeks). During this time you may need to use live migration
and so the possible target host may be running new or old
libvirt / QEMU - particularly during early stages of a rolling
upgrade the majority of nodes will be old libvirt. Hence it
is not uncommon to need to migrate old to new

Daniel

As far as I'm concerned, the only reason you would want to do
that is because you are upgrading your hypervisor pool and,
at some point during the process, you realize there are issues
with the upgrade and need to roll back. As you mention, that
use case would work just fine because the guests have been
defined using an older libvirt versions.
Thinking about it more - even if the domain is defined using a new
libvirt version, as long as the management is still setting
multifunction manually (which will be the case for everything except
auto-added pcie-root-ports), it will still be reflected in the config,
and a migration to a host with older libvirt will still work. This
narrows the scope of "unable to migrate from new->old libvirt even more
- it's only a problem if you define a new domain that auto-adds
pcie-root-ports, or add pcie-root-ports to an existing domain on a "new
libvirt" host, then migrate it to an "old libvirt" host. Since the
auto-adding of pci-root-ports *at all* (much less on multiple functions
of a single slot) is a new feature, and in general it's quite often not
possible to migrate domains that use new features from newer to older
libvirt, I think this is acceptable.
That said, is there any reason why this code can't be moved
to the PostParse callback, so that the multifunction property
will show up in the guest configuration and the issue will be
side-stepped entirely?
I'd rather not pollute new configurations with attributes that aren't
necessary. But more important - if you remove a device from a function
of a slot and end up leaving only the device on function 0, then it
should no longer have multifunction set; when we do the setting of
multifunction automatically at runtime, this will happen by itself, but
if we save the multifunction=on in the config, then it will require
manual intervention.
Normally I would say that it's desirable to record all option settings
in the XML in order to maintain guest ABI, but in this case the existing
setting would be incorrect once the other devices on the slot are
removed, and the act of removing the other devices changes the guest ABI
anyway, so it would/should be expected by the guest.
So does this patch get an ACK? Or am I being too cavalier about
migration compatibility?

function present.

qemu: make PCI multifunction support more manual
When support for was added for PCI multifunction cards (in commit
9f8baf, first included in libvirt 0.9.3), it was done by always
turning on the multifunction bit for all PCI devices. Since that time
it has been realized that this is not an ideal solution, and that the
multifunction bit must be selectively turned on. For example, see
https://bugzilla.redhat.com/show_bug.cgi?id=728174
and the discussion before and after
https://www.redhat.com/archives/libvir-list/2011-September/msg01036.html
This patch modifies multifunction support so that the multifunction=on
option is only added to the qemu commandline for a device if its PCI
<address> definition has the attribute "multifunction='on'",
e.g.:
<address type='pci' domain='0x0000' bus='0x00'
slot='0x04' function='0x0' multifunction='on'/>
In practice, the multifunction bit should only be turned on if
function='0' AND other functions will be used in the same slot - it
usually isn't needed for functions 1-7 (although there are apparently
some exceptions, e.g. the Intel X53 according to the QEMU source
code), and should never be set if only function 0 will be used in the
slot. The test cases have been changed accordingly to illustrate.
With this patch in place, if a user attempts to assign multiple
functions in a slot without setting the multifunction bit for function
0, libvirt will issue an error when the domain is defined, and the
define operation will fail. In the future, we may decide to detect
this situation and automatically add multifunction=on to avoid the
error; even then it will still be useful to have a manual method of
turning on multifunction since, as stated above, there are some
devices that excpect it to be turned on for all functions in a slot.
A side effect of this patch is that attempts to use the same PCI
address for two different devices will now log an error (previously
this would cause the domain define operation to fail, but there would
be no log message generated). Because the function doing this log was
almost completely rewritten, I didn't think it worthwhile to make a
separate patch for that fix (the entire patch would immediately be
obsoleted).
You mentioned in your commit message there, that it would be a valid
enhancement to automatically add multifunction=on, if-and-only-if
we saw other devices with non-0 functions in the same slot.
That all said, the concern I have is that although this change is not
in itself an ABI incompatible change, it does mean that applications
can accidentally trigger ABI incompatible changes in guests.
For example, consider an app has defined a guest with 2 block devs
in the same slot, but not set multifunction=on. Libvirt will silently
set that attribute. Now the app re-defines the guest, but removes
the second block device. libvirt will now not be setting multifunction=on
on the 1st block device. So technically removing the second device has
triggered a silent ABI change on the 1st device.
IMHO, given that apps have to explicitly decide they're going to be
using multifunction and thus manually assign addresses, it is no
great burden for them to have to add multifunction=on explicitly too.
IOW, I'd tend towards dropping this patch, as I don't think the benefit
is compelling enough, and it can lead to surprises for apps.
Regards,
Daniel

New subject: [libvirt] [PATCH v3 7/8] conf: aggregate multiple devices on a slot when assigning PCI addresses
If a PCI device has VIR_PCI_CONNECT_AGGREGATE_SLOT set in its
pciConnectFlags, then during address assignment we allow multiple
instances of this type of device to be auto-assigned to multiple
functions on the same device. A slot is used for aggregating multiple
devices only if the first device assigned to that slot had
VIR_PCI_CONNECT_AGGREGATE_SLOT set. but any device types that have
AGGREGATE_SLOT set might be mix/matched on the same slot.
(NB: libvirt should never set the AGGREGATE_SLOT flag for a device
type that might need to be hotplugged. Currently it is only planned
for pcie-root-port and possibly other PCI controller types, and none
of those are hotpluggable anyway)
There aren't yet any devices that use this flag. That will be in a
later patch.

I noticed most of the pcie-root-ports get a new value for the
port attribute after the change, while the chassis attribute
remains always the same AFAICT.
That's because the chassis attribute is just set to the index of the
controller, while port is set to slot<<3 + function (this was
recommended by some PCI person, Alex I think). I believe chassis needs
to be unique within the entire machine, while port needs to be unique
only for the bus that the controller is connected to.

Again, I don't think this is a problem at all, but it would
be nice to get a confirmation the attributes are indeed
being used properly. Is their meaning documented anywhere?

ARGH!
In my final rebase before pushing, I pulled in Andrea's patches that
switch aarch64/virt to using PCI by default, and the test case for that
resulted in a make check failure:
564) QEMU XML-2-ARGV aarch64-virtio-pci-default ... libvirt: QEMU Driver
error : unsupported configuration: 'multifunction=on' is not supported
with this QEMU binary FAILED
Is it really true that the aarch64 qemu doesn't support multifunction
devices? If so, that really needs to be fixed. In the meantime, this
means I still can't push my patches, because doing so will break
aarch64. I'll try to come up with a patch to conditionalize
AGGREGATE_SLOT on support for multifunction (which I suppose I should
have done to begin with, but I wouldn't have expected that a platform
that supports PCIe doesn't support multifunction devices :-/)

ARGH!
In my final rebase before pushing, I pulled in Andrea's patches that switch
aarch64/virt to using PCI by default, and the test case for that resulted in
a make check failure:
564) QEMU XML-2-ARGV aarch64-virtio-pci-default ... libvirt: QEMU Driver
error : unsupported configuration: 'multifunction=on' is not supported with
this QEMU binary FAILED
Is it really true that the aarch64 qemu doesn't support multifunction
devices? If so, that really needs to be fixed. In the meantime, this means I
aarch64 qemu does support multifunction. It's been a while since I
experimented with it, but it worked when I did. Maybe just a make
check fix is needed?
Thanks,
drew
still can't push my patches, because doing so will break aarch64.
I'll try
to come up with a patch to conditionalize AGGREGATE_SLOT on support for
multifunction (which I suppose I should have done to begin with, but I
wouldn't have expected that a platform that supports PCIe doesn't support
multifunction devices :-/)

aarch64 qemu does support multifunction. It's been a while since I
experimented with it, but it worked when I did. Maybe just a make
check fix is needed?
Derp. Of course - it's just a missing capability flag in Andrea's new
test case (which wasn't needed until I started doing stuff that required
multifunction)m *not* a missing capability in the aarch64 qemu binary.
Once I fix that it's of course passing the test.
Thanks for jarring my brain into proper thought!

ARGH to you too :)
In my final rebase before pushing, I pulled in Andrea's patches
that
switch aarch64/virt to using PCI by default, and the test case for that
resulted in a make check failure:
564) QEMU XML-2-ARGV aarch64-virtio-pci-default ... libvirt: QEMU Driver
error : unsupported configuration: 'multifunction=on' is not supported
with this QEMU binary FAILED
Is it really true that the aarch64 qemu doesn't support multifunction
devices? If so, that really needs to be fixed. In the meantime, this
means I still can't push my patches, because doing so will break
aarch64.
I think the only problem is that current aarch64 test cases
don't enable the QEMU_CAPS_PCI_MULTIFUNCTION capability.
I will try this on actual hardware now and get back to you,
but really that's all you should have to do in order not to
break the test suite with your changes.
I'll try to come up with a patch to conditionalize
AGGREGATE_SLOT on support for multifunction (which I suppose I should
have done to begin with, but I wouldn't have expected that a platform
that supports PCIe doesn't support multifunction devices :-/)
That's a good idea in any case, yes. However, realistically
speaking, I think your initial intuition that all platforms
that support PCIe also support multifunction still holds as
far as real-world scenarios are concerned.

don't enable the QEMU_CAPS_PCI_MULTIFUNCTION capability.
Yes. That's correct. I don't know what I was (or wasn't) thinking. It's
all fixed now, and ready to push.
I will try this on actual hardware now and get back to you,
but really that's all you should have to do in order not to
break the test suite with your changes.

That's a good idea in any case, yes.
Yeah, I'm planning on doing that in a cleanup patch. I wrote one last
night but it was somehow broken and I was too tired to figure out why,
so I'll save it for later.
However, realistically
speaking, I think your initial intuition that all platforms
that support PCIe also support multifunction still holds as
far as real-world scenarios are concerned.
