[Qemu-ppc] [PATCH v8 0/7] sPAPR: Support EEH Error Injection |
Date: |
Mon, 14 Sep 2015 11:36:08 +1000 |
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
=========
v8:
* Rebased to git://github.com/dgibson/qemu.git (branch: spapr-next)
* Apply "git -C $to commit" to update-linux-headers.sh.
* Use "git rev-parse --short HEAD" to retrieve top commit
* Use "EOF" to construct the commit message
* Drop sPAPRPHBClass::eeh_inject_error().
v7:
* Cover comments from Peter Maydell in scripts/update-linux-headers.sh.
* Reset spapr->errinjct_token when rebooting guest.
v6:
* Improved scripts/update-linux-headers.sh to format commit log with
last commit ID and Linux kernel version. Also, "stdint.h" is allowed
to be included in virtio headers.
* #include "asm-powerpc/eeh.h".
* Incremental spapr->errinjct_token so that the condition (0x1 &
spapr->errinjct_token) can be used to check if the token is valid.
* Big-endian tokens in /rtas/ibm,errinjct-tokens.
* Pick rtas_ldq() to load 64-bits value from RTAS call buffer, which
was dropped in v2.
* Use EEH_ERR_FUNC_MAX to validate EEH error function.
* Removed unnecessary paranthesitis.
v5:
* Put "errinjct_token" to migration stream disregarding it's opened or
not. Also, it starts to be supported from v4 vmstate_spapr.
* Include powerpc/include/uapi/asm/eeh.h in scripts/update_linux_headers.sh
v4:
* To record currently opened token, not next one as suggested by Alexey.
v3:
* Replace random token number with incremental counter. Another boolean
variable to track if it's opened. Both of them are added to migration
stream.
* The return value from sPAPRPHBClass::eeh_inject_error() can be passed
to user directly. No need to do conversion.
* Corrected error code to RTAS_OUT_CLOSE_ERROR in rtas_ibm_errinjct().
* Don't expose error injection tokens for unsupported types.
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.
