This makes testing the NVDIMM health reporting functionality # difficult as simulating NVDIMM health related events need a hacked up # qemu version. # # To solve this problem this patch proposes simulating certain set of # NVDIMM health related events in papr_scm. Specifically 'fatal' health # state and 'dirty' shutdown state. These error can be injected via the # user-space 'ndctl-inject-smart(1)' command. With the proposed patch and # corresponding ndctl patches following command flow is expected: # # $ sudo ndctl list -DH -d nmem0 # ... # "health_state":"ok", # "shutdown_state":"clean", # ... # # inject unsafe shutdown and fatal health error # $ sudo ndctl inject-smart nmem0 -Uf # ... # "health_state":"fatal", # "shutdown_state":"dirty", # ... # # uninject all errors # $ sudo ndctl inject-smart nmem0 -N # ... # "health_state":"ok", # "shutdown_state":"clean", # ... # # The patch adds a new member 'health_bitmap_inject_mask' inside struct # papr_scm_priv which is then bitwise ANDed to the health bitmap fetched from the # hypervisor. The value for 'health_bitmap_inject_mask' is accessible from sysfs # at nmemX/papr/health_bitmap_inject. # # A new PDSM named 'SMART_INJECT' is proposed that accepts newly # introduced 'struct nd_papr_pdsm_smart_inject' as payload thats # exchanged between libndctl and papr_scm to indicate the requested # smart-error states. # # When the processing the PDSM 'SMART_INJECT', papr_pdsm_smart_inject() # constructs a pair or 'inject_mask' and 'clear_mask' bitmaps from the payload # and bit-blt it to the 'health_bitmap_inject_mask'. This ensures the after being # fetched from the hypervisor, the health_bitmap reflects requested smart-error # states. # # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Signed-off-by: Shivaprasad G Bhat <sbhat@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20220124202204.1488346-1-vaibhav@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 bbbca72352bb9484bc057c91a408332b35ee8f4c # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64le_defconfig # Added to kconfig CONFIG_KPROBES=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_ppc64le_defconfig+NO_KPROBES_powerpc-gcc5 # Build took: 0:03:20.075773
