This series first renders TYPE_PIIX3_XEN_DEVICE redundant and finally removes
it. The motivation is to 1/ decouple PIIX from Xen and 2/ to make Xen in the PC
machine agnostic to the precise southbridge being used. 2/ will become
particularily interesting once PIIX4 becomes usable in the PC machine, avoiding
the "Frankenstein" use of PIIX4_ACPI in PIIX3.
v2:
- xen_piix3_set_irq() is already generic. Just rename it. (Chuck)
Testing done:
None, because I don't know how to conduct this properly :(

"[PATCH v4 00/30] Consolidate PIIX south bridges"

If it doesn't work for you let me know, then I can rebase onto master. All necessary dependencies for the series are upstreamed meanwhile. > > > >Ping > > Ping^2 Hi Bernhard, I took a look at this today to see why it cannot be applied. I can see clearly that all the prerequisite patches have *not* been applied to master yet, so I can understand why Anthony cannot pull this up yet. Specifically, the series that consolidates PIIX3 and PIIX4 south bridges is not yet applied, and that is one of the prerequisites. I think you said it was reviewed, but it apparently never got pulled up into master. For reference, here is the link to the prerequisite patch set I tested with this patch set: https://lore.kernel.org/qemu-devel/20221221170003.2929-1-shentey@gmail.com/ The patch set I tested is a 30-patch series, and I don't know if it has been partially applied. The title of that patch set is: This series consolidates the implementations of the PIIX3 and PIIX4 south So before this patch set to resolve the TYPE_PIIX3_XEN_DEVICE can be applied, the patch set to consolidate the PIIX3 and PIIX4 south bridges needs to be applied. I don't know if the feature freeze means these patches that do not add any new features still need to wait until the next development cycle.

This series currently depends on it to avoid merge conflicts but doesn't need it otherwise. Back then I anticipated that the consolidation series would land in master soon since it was fully reviewed before this one. But that turned out not to be the case. This series depends on some necessary refactoring [1] which I did in the context of PIIX consolidation which is already in master. So this series can easily be rebased onto master and it even simplifies the consolidation series a bit. I'll take this route now and I'll post a v3.

So this series can easily be rebased onto master and it even simplifies the consolidation series a bit. I'll take this route now and I'll post a v3. Thanks for posting v3, I was at a loss trying to figure out how to merge the 30-patch piix consolidation series into the master branch. I just tested your recent v3 (all 6 patches) on top of the current master branch and it works well on my Xen guests, so you can keep my Tested-by tag on that patch series! Kind regards, Chuck

I can rebase to master if that eases review -- please let me know.
