I forgot to note the list of changes against v1, so here goes an arbitrary list
of some changes that I remember (can suck out of e-mail history):
- SMM=on/off is allowed to be specified for i440fx
- More use of virXMLFormatElement
- Fixed some commit messages
- Fixed wording and some details in docs
- Don't record the size of extended TSEG in config XML if not explicitly requested

qemu: Move checks for SMM from command-line creation into validation
phase
conf, schema, docs: Add support for TSEG size setting

New subject: [libvirt] [PATCH 1/4] qemu: Move checks for SMM from command-line creation into validation phase
We are still hoping all of such checks will be moved there and this is one small
step in that direction.
One of the things that this is improving is the fact that instead of error
message *that was wrong) you get when starting a domain with SMM and i440fx we
allow the setting to go through. SMM option exists and makes sense on i440fx as
well (basically whenever that _SMM_OPT capability is set).

Here you are suggesting to split it into two. I'm fine with both, just tell me
what you meant so I can fix it up, thanks.

Summary adjusted OR changes split, IOW: don't leave functional changes
in the commit named 'Move'
Of course, the split is nicer.

New subject: [libvirt] [PATCH 2/4] conf, schema, docs: Add support for TSEG size setting
TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy. This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real
q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

New subject: [libvirt] [PATCH 2/4] conf, schema, docs: Add support for TSEG size setting
On 06/07/18 10:37, Martin Kletzander wrote:
TSEG (Top of Memory Segment) is one of many regions that SMM (System
Management
Mode) can occupy. This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real
q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

+ This value is configurable due to the fact that the calculation cannot

+ QEMU, the user-configurable extended TSEG feature was unavailable up
+ to and including <code>pc-q35-2.9</code>. Starting with
+ <code>pc-q35-2.10</code> the feature is available, with default
size
+ 16 MiB. That should suffice for up to roughly 272 VCPUs, 5 GiB guest
+ RAM in total, no hotplug memory range, and 32 GiB of 64-bit PCI MMIO
+ aperture. Or for 48 VCPUs, with 1TB of guest RAM, no hotplug DIMM
+ range, and 32GB of 64-bit PCI MMIO aperture. The values may also vary
+ based on the loader the VM is using.
+ </p><p>
+ Additional size might be needed for significantly higher VCPU counts
+ or increased address space (that can be memory, maxMemory, 64-bit PCI
+ MMIO aperture size; roughly 8 MiB of TSEG per 1 TiB of address space)
+ which can also be rounded up.
+ </p><p>
+ Due to the nature of this setting being similar to "how much RAM
+ should the guest have" users are advised to either consult the
+ documentation of the guest OS or loader (if there is any), or test
+ this by trial-and-error changing the value until the VM boots
+ successfully. Yet another guiding value for users might be the fact
+ that 48 MiB should be enough for pretty large guests (240 VCPUs and
+ 4TB guest RAM), but it is on purpose not set as default as 48 MiB of
+ unavailable RAM might be too much for small guests (e.g. with 512 MiB

New subject: [libvirt] [PATCH 3/4] qemu: Add capability flag for setting the extended tseg size
For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe. From the differences I only extracted the reply to the new
QMP command and discarded the rest. For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.
In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability. Then removed that one property.
After that I used test/qemucapsfixreplies to fix the reply IDs.

New subject: [libvirt] [PATCH 3/4] qemu: Add capability flag for setting the extended tseg size
On Thu, Jun 07, 2018 at 10:37:42AM +0200, Martin Kletzander wrote:
For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe. From the differences I only extracted the reply to the new
QMP command and discarded the rest. For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.
In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability. Then removed that one property.
After that I used test/qemucapsfixreplies to fix the reply IDs.

New subject: [libvirt] [PATCH 4/4] qemu: Add support for setting the TSEG size
The default is stable per machine type so there should be no need to keep that.

I wouldn't want to disable that option now in a way that we won't be able to fix
later. So from my point of view it makes sense.

Why this change?
IIUC if they weren't specified on both sides, they should both be 0
here.
If you're sure it's needed, put it in the commit adding this check.
Oh, it is very easy to explain. The first line (the one being removed) is from
the previous version of this series. The second one (which is being added) is
from version two in which case I used fixup during interactive rebase on a wrong
commit. Otherwise this would be part of the commit in which this was added.
And as said in the other reply to Laszlo's e-mail (which I had to separate due
to this par tof review being omitted there) it makes sense for the tseg size to
be 0 as that means the extended size is disabled. I agree that it should be
part of the documentation, though.
@Laszlo: When thinking about it, even though it is a very stupid idea,
technically there isn't really a difference between 'extended-tseg-mbytes=0'
and
'extended-tseg-mbytes=8' (of course the second option will still provide a
fw_cfg info about the size etc., but the guest will behave the same way), right?
That brings me to another question (maybe even more stupid), what size does OVMF
choose if I specify 'extended-tseg-mbytes=6'?

- it's not fw_cfg but a made-up register in PCI config space
- the guest won't behave *exactly* the same way, technically speaking,
but the end result will be 8MB in both cases, yes.
That brings me to another question (maybe even more stupid), what
size
does OVMF choose if I specify 'extended-tseg-mbytes=6'?
6MB.
Thanks,
