[OS-BUILD PATCH] redhat/configs: Fix CONFIG_VIRTIO_IOMMU to 'y' on aarch64
From: Eric Auger
redhat/configs: Fix CONFIG_VIRTIO_IOMMU to 'y' on aarch64
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1972795
Upstream Status: RHEL only
Tested: on ARM with qemu (Jean-Philippe Brucker's qemu branch as the
qemu integration is not yet upstream, with both protected virtio-blk-pci
and a virtio-net-pci devices)
Commit fe6d9534dbe4 ("redhat/configs: Set CONFIG_VIRTIO_IOMMU on aarch64")
enabled the compilation of the virtio-iommu driver on ARM but set the
config to 'm'. However if there are devices behind the vIOMMU that are
needed during the boot such as a virtio-blk-pci device, the guest fails
to boot as the driver is not loaded. Let's fix this bootstrap issue
by compiling the driver in-kernel as it is done for other iommu drivers.

From: Eric Auger on gitlab.com https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1158#note_590150212 Yes. I meant this would deserve separate enablement and testing at libvirt level AND qemu level. I guess the pvpanic-pci device is not compiled either at qemu level for x86. Anyway I would be in favour of handling this in a separate BZ if we decide to support it. I can raise the point on virt-devel.

Re: [OS-BUILD PATCH] redhat/configs: Set PVPANIC_MMIO for x86 and PVPANIC_PCI for aarch64
From: Eric Auger on gitlab.com
https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1158#note_585765138
As far as I understand, 6861d27cf590 ("misc/pvpanic: split-up generic and
platform dependent code") split the legacy tristate PVPANIC_CONFIG into 2
configs:
the bool PVPANIC and the tristate PVPANIC_MMIO. To get the same functionality
as before you need to set both. Then pvpanic-pci was added by db3a4f0abefd
("misc/pvpanic: add PCI driver") which brought the new PVPANIC_PCI config. To
use the ISA device I understand you need to set the MMIO config.
By the way I now guess I should set "m" instead of "y" for the MMIO and PCI.
