[libvirt] [PATCHv2 0/5] S390: Support for native CCW bus
Originally, QEMU did not implement a native I/O bus for s390. The initial implementation had a machine type 's390-virtio' featuring a fully paravirtualized I/O system with an artificial bus type 'virtio-s390'. This bus had a number of short-comings, like the need for a non-standard device discovery mechanism, a limited number of devices, limited hotplugging capabilites and the lack of persistent device addresses. To resolve these issues a new machine type 's390-ccw-virtio' has been recently added to QEMU which implementa the native s390 CCW I/O bus. Guests with arch='s390x' and machine='s390-ccw-virtio' can now be defined with up to 262144 virtio devices. This series adds the support for the s390-ccw-virtio machine type and the CCW bus to libvirt. As usual we start with the documentation/schema, the generic configuration stuff, continue with the QEMU driver including device hotplug and finally add qemu2xml testcases. V2 Changes - use an attribute triple cssid, ssid, schid instead of devno to better represent the libvirt CCW address structure - rebase to current upstream, mainly address qemuCapsXXX rename J.B.

The native bus for s390 I/O is called CCW (channel command word). As QEMU has added basic support for the CCW bus, i.e. the ability to assign CCW devnos (bus addresses) to devices. Domains with the new machine type s390-ccw-virtio can use the CCW bus. Currently QEMU will only allow to define virtio devices on the CCW bus. Here we add the new machine type and the new device address to the schema definition and add a new paragraph to the domain XML documentation.

This commit adds the QEMU driver support for CCW addresses. The current QEMU only allows virtio devices to be attached to the CCW bus. We named the new capability indicating that support QEMU_CAPS_VIRTIO_CCW accordingly. The fact that CCW devices can only be assigned to domains with a machine type of s390-ccw-virtio requires a modification in the capability handling approach. First, the QEMU binary name alone will not suffice for capability lookup, we need the machine type as well. For that purpose we mangle the machine type into the cache lookup key. The other thing is that the device support probing will unfortunately always return both the old virtio-*-s390 and the new virtio-*-ccw devices. This makes it impossible to choose the correct default device address type if the domain definition XML doesn't contain explict addresses. Therefore we apply a fix up in the cache lookup: depending on the machine type we clear either the VIRTIO_S390 or the VIRTIO_CCW capability. The rest is more straight-forward, but since it's a new address type, a bit bulky. The majority of the new functions deals with CCW address generation and management.

This commit adds the QEMU driver support for CCW addresses. The current QEMU only allows virtio devices to be attached to the CCW bus. We named the new capability indicating that support QEMU_CAPS_VIRTIO_CCW accordingly.
The fact that CCW devices can only be assigned to domains with a machine type of s390-ccw-virtio requires a modification in the capability handling approach.
First, the QEMU binary name alone will not suffice for capability lookup, we need the machine type as well. For that purpose we mangle the machine type into the cache lookup key.
The other thing is that the device support probing will unfortunately always return both the old virtio-*-s390 and the new virtio-*-ccw devices. This makes it impossible to choose the correct default device address type if the domain definition XML doesn't contain explict addresses. Therefore we apply a fix up in the cache lookup: depending on the machine type we clear either the VIRTIO_S390 or the VIRTIO_CCW capability.
I'm not a fan of this approach. The capabilities data is reflecting what the QEMU binary is capable of supporting, *regardless* of what guest config is chosen. The decision about whether to use S390 or CCW based on the machine type value, should be made by the internal method at the point when it actually assigns addresses, not when we create the capabilities initially. Your approach here means we're going to be storing many many more capabilities instances, and we're going to be re-probing the QEMU binaries for each machine type. This is absolutely not something we want todo.

not convinced this is the best possible definition ... we would have seen more issues with it if the machine type would really have had a meaning on other architectures, e.g., if -M isapc would not allow to instantiate PCI devices. But since...
The decision about whether to use S390 or CCW based on the machine type value, should be made by the internal method at the point when it actually assigns addresses, not when we create the capabilities initially.
...I can certainly use the vm definition to figure out which address type to choose that should work. Let me run a few tests to prove that and I will come back with a V3 for 3-5/5 in the next couple of days. -- Mit freundlichen Grüßen/Kind Regards Viktor Mihajlovski IBM Deutschland Research & Development GmbH Vorsitzender des Aufsichtsrats: Martin Jetter Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen Registergericht: Amtsgericht Stuttgart, HRB 243294

From: "J.B. Joret" <jb@linux.vnet.ibm.com> We didn't yet expose the virtio device attach and detach functionality for s390 domains as the device hotplug was very limited with the old virtio-s390 bus. With the CCW bus there's full hotplug support for virtio devices in QEMU, so we are adding this to libvirt too. Since the virtio hotplug isn't limited to PCI anymore, we change the function names from xxxPCIyyy to xxxVirtioyyy, where we handle all three virtio bus types. Signed-off-by: J.B.
