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
