The -2.8 and -2.9 machine types of the i440fx and q35 machines are
older than 6 years, so according to our support policy we can remove
them, together with a lot of the compatibility knobs that they were
using.
This is a respin of Philippe's original series here:
https://lore.kernel.org/qemu-devel/[email protected]
The following three patches still need a review:
- hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition
- hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field
- tests/qtest/test-x86-cpuid-compat: Remove the test with the i440fx-2.9 machine
Changes in v2:
- Rebased all patches to current master, and fixed the contextual conflicts
- Added Igor's Reviewed-bys
- Dropped the "hw/southbridge/ich9: Remove ICH9_LPC_SMI_F_BROADCAST_BIT
definition" patch since the code is still required (the guest can decide
whether to use this feature or not)
- Dropped the two "hw/nvram/fw_cfg" patches since Igor mentioned that it
still might be useful to keep this configuration knob
- Fix "hw/pci/pcie: Remove QEMU_PCIE_EXTCAP_INIT definition" according to
Igor's review
- Adjusted "hw/i386/x86-iommu: Remove X86IOMMUState::pt_supported field":
The problematic hunk has already been merged in upstream, so I dropped
it from this patch.
- Added the final patch to drop a qtest that required this machine

If there are no objections (and Paolo or Michael do not plan to take these
with their next pull request anyway), I'll add these patches (excluding 17
which needs some more work) to my next pull request, so that we finally get
these in before the next softfreeze.
