[Qemu-devel] [PATCH v2 0/3] sPAPR: Support EEH Error Injection

[Gavin Shan <gwshan@linux.vnet.ibm.com>]

The patchset depends on below Linux upstream commits:

  commit ed3e81f ("powerpc/eeh: Move PE state constants around")
  commit ec33d36 ("powerpc/eeh: Introduce eeh_pe_inject_err()")

According to PAPR specification 2.7, there're 3 RTAS calls relevent to error
injection: "ibm,open-errinjct", "ibm,close-errinjct", "ibm,errinjct". The 
userland utility "errinjct" running on guest utilizes those 3 RTAS calls like
this way: Call "ibm,open-errinjct" that returns open-token, which is passed to 
"ibm,errinjct" together with error specific arguments to do error injection.
Finally, to return the open-token by calling "ibm,close-errinject".

"ibm,errinjct" can be used to inject various errors, not limited to EEH errors.
However, this patchset is going to support injecting EEH errors only for VFIO
PCI devices.

Changelog
=========
v1 -> v2:
   * Rebased to git://github.com/dgibson/qemu.git (branch: spapr-next)
   * Remove specific PCI error types in hw/ppc/spapr.h. Use those macros
     asm-powerpc/eeh.h instead.
