[PATCH v11 00/14] vfio-user server in QEMU

Posted by Jagannathan Raman 1 year, 11 months ago

Hi,

This is v11 of the server side changes to enable vfio-user in QEMU.

Thank you for reviewing and sharing your feedback for the previous
revision. We have addressed your comments in this revision.

We made the following changes in this series:
[PATCH v11 13/14] vfio-user: handle device interrupts
  - Added msi_set_irq_state() and msix_set_irq_state() to mask
    and unmask individual MSI(x) vectors
  - Implement callbacks to handle the MASK/UNMASK actions
    initiated by SET_IRQS message
  - vfu_object_set_bus_irq() sets the maximum number of IRQS
    to max BDF. This only affects devices using INTx - allows
    multiple devices to use INTx

Thank you very much!

Jagannathan Raman (14):
  qdev: unplug blocker for devices
  remote/machine: add HotplugHandler for remote machine
  remote/machine: add vfio-user property
  vfio-user: build library
  vfio-user: define vfio-user-server object
  vfio-user: instantiate vfio-user context
  vfio-user: find and init PCI device
  vfio-user: run vfio-user context
  vfio-user: handle PCI config space accesses
  vfio-user: IOMMU support for remote device
  vfio-user: handle DMA mappings
  vfio-user: handle PCI BAR accesses
  vfio-user: handle device interrupts
  vfio-user: handle reset of remote device
