[libvirt] [PATCH v5 00/12] qemu: Validate PCI controller options
Applies cleanly on top of 328b8dbe8bee9939c7108fdec4fda05fd02511f6. Changes from [v4]: * patch 1/12 is new; * use virReportEnumRangeError(), as suggested by laine. Changes from [v3]: * don't introduce new test cases that won't be able to provide full test coverage anyway, as suggested by laine. Changes from [v2]: * replace the old implementation bit by bit using a clever trick suggested by pkrempa; * don't move QEMU capability validation; * add a default: label to all switch statements as recommended by danpb. Changes from [v1]: * error out instead of silently accept invalid options; * shave quite a lot of yaks.

I'm not sure why you want it, but don't see any harm (if it's for consistency, there are many other enums that don't explicitly list the first item as 0). Reviewed-by: Laine Stump <laine@laine.org>
The esisting function is renamed and called from the new one, so that even while we're in the process of implementing new checks all the existing ones will be performed.

Sure. Seems as reasonable a way as any to add the new and remove the old without ending up with confusing diffs. Reviewed-by: Laine Stump <laine@laine.org>

I'm not sure I see the advantage of grouping the validation for a single attribute on several different controller models together, rather than the current code's grouping validation for all attributes on a single controller together. Potato-potahto. It does mean that if you're hand tracing the code you need to go through the entire function rather than just one section. On the other hand, I guess it does mean that many instances of "attribute X isn't valid for Y controller" can be combined.

I've given it a try and it makes things quite a bit nicer. Showing the controller index is also very useful, as some controllers can show up multiple times in a guest. A couple error messages might have gotten slightly less informative as a result, but I'd say it's acceptable as long as there's enough context to help the user look it up in the documentation. [...]

Just a temporary brain fart: I've gotten it right in subsequent patches, and I've now fixed it here as well.

Yeah, structuring the code this way allows to provide better error messages (eg. spelling out which specific option is missing) without resulting in an endless amount of repetition; it also makes adding checks for all options when introducing a new controller model more difficult to forget, though unfortunately it doesn't help when adding a new option instead. -- Andrea Bolognani / Red Hat / Virtualization

Correct: virDomainControllerPCIModelNameToQEMUCaps() would return QEMU_CAPS_DEVICE_SPAPR_PCI_HOST_BRIDGE, and the check below would fail. I'm actually fairly confident we could drop that hunk with no ill effect, because the spapr-pci-host-bridge must have existed even before we started checking for it, even if it might possibly have been, at some point, not user-instantiable; however, the capabilities data for ppc64 in our test suite doesn't go far back enough to prove this is the case, so special-casing it seems like the safest option. I'll try to see if I can build QEMU 1.2.0 (that's the earliest we claim support for, right?) on ppc64 with a reasonable amount of work, and if my hunch is correct I'll post a follow-up cleanup patch that gets rid of it. -- Andrea Bolognani / Red Hat / Virtualization

I'm actually fairly confident we could drop that hunk with no ill effect, because the spapr-pci-host-bridge must have existed even before we started checking for it, even if it might possibly have been, at some point, not user-instantiable; however, the capabilities data for ppc64 in our test suite doesn't go far back enough to prove this is the case, so special-casing it seems like the safest option.

It's actually 0.12, not 1.2.0. Whoops. According to my research, the pSeries machine type was introduced in 0.15 but didn't have PCI support until 1.0, by which point the spapr-pci-host-bridge device had been introduced too. tl;dr the hunk in question can safely be dropped. I'll respin. -- Andrea Bolognani / Red Hat / Virtualization
We've implemented all existing checks, and more, in the new function, so we can finally drop the old one.
