[Qemu-devel] [RFC v5 0/8] KVM PCI/MSI passthrough with mach-virt

[Qemu-devel] [RFC v5 0/8] KVM PCI/MSI passthrough with mach-virt

[Eric Auger]

On ARM, MSI transactions emitted by passthrough'ed devices are translated
by the IOMMU.  So the host must allocate IOVAs and map them to the host
MSI frame physical addresses. Those IOVAs must be allocated within safe
GPA slots, unused by the guest.

The QEMU VFIO device retrieves the size if the IOVA window needed by the
host using a new VFIO IOMMU type capability chain API. This window is
allocated on guest address space withing the platform bus memory container.
This latter acts as a pool of usable GPA and comes with its own GPA allocator.
The memory region is tagged as "reserved_iova". The vfio_listener_region_add
callback is in charge of passing the window characteristics to the kernel
through an extended VFIO_IOMMU_MAP_DMA ioctl.

Best Regards

Eric

Dependencies:
The series depends on the not yet upstream kernel series:
[PATCH v14 00/16] KVM PCIe/MSI passthrough on ARM/ARM64,
https://lkml.org/lkml/2016/10/12/347

Git:
https://github.com/eauger/qemu/tree/v2.7.0-passthrough-rfc-v5

History:

RFC v4 -> RFC v5:
- update linux header according to last user API changes introduced in
  [PATCH v14 00/16] KVM PCIe/MSI passthrough on ARM/ARM64
- fix compilation issue on platforms not setting CONFIG_PLATFORM_BUS
- squash [RFC v4 3/8] hw: vfio: common: Introduce vfio_register_msi_iova
  into the last patch to avoid compilation warning

RFCv3 -> RFC v4:
- initialize err to NULL in vfio_connect_container and fix hint

RFCv2 -> RFC v3:
- IOVA aperture size is not arbitrary anymore. It is retrieved from the host
  usig VFIO IOMMU type capability chain API
- GPEX related patches removed since the warning is not seen anymore

RFC v1 -> RFC v2:
- now uses platform bus MMIO for mapping reserved IOVA region; hence the
  new patch file:
  "hw: platform-bus: enable to map any memory region onto the platform-bus"

Eric Auger (8):
  linux-headers: Partial update for MSI IOVA handling

[Qemu-devel] [RFC v5 3/8] memory: Add reserved_iova region type

[Eric Auger]

Introduce a new reserved_iova region type. This type of iova region
is bound to be used by the kernel to map some host physical addresses
(typically MSI frames).

A new initializer, memory_region_init_reserved_iova is introduced, as
well as a test function, memory_region_is_reserved_iova.

[Qemu-devel] [RFC v5 5/8] hw: platform-bus: Enable to map any memory region onto the platform-bus

[Eric Auger]

The platform bus is currently used to map dynamically instantiable
platform device MMIO regions. The platform bus also can be seen as a
pool of free guest physical addresses. We would like to use that pool
to allocate a contiguous reserved IOVA region usable for MSI message
address IOMMU mapping.

This patch introduces platform_bus_map_region which enables to map any
memory region onto the platform bus.

[Qemu-devel] [RFC v5 7/8] hw: vfio: common: vfio_prepare_msi_mapping

[Eric Auger]

Introduce an helper function to retrieve the iommu type1 capability
chain info.

The first capability ready to be exploited is the msi resv
capability. vfio_prepare_msi_mapping allocates a MemoryRegion
dedicated to host MSI IOVA mapping. Its size matches the host needs.
This region is mapped on guest side on the platform bus memory container.

[Qemu-devel] [RFC v5 8/8] hw: vfio: common: Adapt vfio_listeners for reserved_iova region

[Eric Auger]

In case of reserved iova region, let's declare this region to the
kernel so that it can use it for IOVA/HPA bindings.

This is achieved through the new vfio_register_msi_iova helper.

I can't figure out why this rule is missing?

I compiled on x86 and aarch64 with

This may be a Makefile bug, but can you move it the file to
stubs/platform-bus.c? There you won't need the Makefile logical calculation..

I think the reason it doesn't work is this: common-obj-y objects are built as
prerequisite of $(SUBDIR_RULES) which is defined in Makefile, from which the
unnest of common-obj-y doesn't include this stub object, because Makefile
doesn't read default-config; later make enters Makefile.target, this time
common-obj-y _includes_ platform-bus-stub.o, but the object rule doesn't work
there.

I think the easiest solution is still move the stub function to stubs/, or
otherwise you need to fix Makefile or rules.mak for this to work.

Many thanks for this analysis.

I will move the stub functions in stubs/ if it does the same job.

Thanks
