Can I inject a uncorrected error or only corrected errors using the
layerscape edac driver injection via sysfs?
Is this the expected output for the edac-util on layerscape when
injecting errors?
root@ls1043ardb:~# edac-util -v
mc0: 0 Uncorrected Errors with no DIMM info
mc0: 0 Corrected Errors with no DIMM info
mc0: csrow0: 0 Uncorrected Errors
mc0: csrow0: mc#0csrow#0channel#0: 643 Corrected Errors
root@ls1043ardb:~# edac-util -vs
edac-util: EDAC drivers are loaded. 1 MC detected:
mc0:fsl_mc_err
root@ls1043ardb:~# edac-util
mc0: csrow0: mc#0csrow#0channel#0: 2700 Corrected Errors
Does edac-ctl function on ARM based platforms or only on x86 and why
might it show 0MB for the memory layout for DDR4 as below?
/run/media/nvme0n1p1/tls/neo_mcu-kernel/drivers/edac-utils# edac-ctl
