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


From: Gavin Shan
Subject: [Qemu-devel] [PATCH 0/3] Support EEH Error Injection
Date: Wed, 11 Mar 2015 17:39:29 +1100

The patchset depends on the corresponding host kernel changes:

https://patchwork.ozlabs.org/patch/448824/
https://patchwork.ozlabs.org/patch/448823/

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.

Gavin Shan (3):
  linux-headers: Sync vfio.h
  sPAPR: Support RTAS call ibm,{open,close}-errinjct
  sPAPR: Support RTAS call ibm,errinjct
