[Qemu-devel] [PATCH v8 0/4] EEH Support for VFIO PCI Device

[Gavin Shan]

The series of patches adds support EEH for VFIO PCI devices on sPAPR platform.
It requires corresponding host kernel support. Also, it is based on top of
Alexey's VFIO-for-sPAPR git repository.

QEMU:   git://github.com/aik/qemu.git (branch: vfio)
Kernel: git://github.com/aik/linux.git (branch: vfio)
Kernel:

The implementations notes are below. Please comment.

* RTAS calls are received in spapr_pci.c, sanity check is done there. RTAS
  handlers handle what they can. If there is something it cannot handle and
  sPAPRPHBClass::eeh_handler callback is defined, it is called.
* sPAPRPHBClass::eeh_handler is only implemented for VFIO now. It does ioctl()
  to the IOMMU container fd to complete the call. Error codes from that ioctl()
  are transferred back to the guest.

Gavin Shan (4):
  sPAPR: Implement EEH RTAS calls
  headers: Update kernel header
  VFIO: Introduce helper vfio_pci_container_ioctl()
  sPAPR: Implement sPAPRPHBClass::eeh_handler
