Addition of Error Correction Type information

[realies]

It would be great to start integrating ECC/EDAC support in unRAID, one of the first steps might be to display relevant information from the BIOS/UEFI.

Reducing the dmidecode -t 16 calls to one is preferable, I am not aware if Maximum Capacity and Error Correction Type can be extracted with awk in one go without having to explode the row as done with $cache, otherwise it would be fine.

Just a update: I'm enabling EDAC support in the linux kernel

[realies]

@eschultz, good to know. Is this expected to be available in the next RC? Looking forward to testing this on an ECC enabled X370 platform.

@realies We jumped up to kernel 4.13.4 and added EDAC so if the new kernel checks out (i'm sure it will) then it'll all be included in the next RC. Kernel 4.12.x is EOL now.

You can combine both searches in a single awk statement. Like this

list($memory_maximum,$ecc_support) = array_map('trim',explode('#',exec("dmidecode -t16|awk -F: '/^\tMaximum Capacity: [0-9]+ GB$/{t+=$2};/^\tError Correction Type:/{e=$2} END{print t\"#\"e}'")));

And make a single echo statement. Like this

echo "$memory_installed GB ".($ecc_support=='None'?"":"$ecc_support ")."(max. installable capacity $memory_maximum GB)$star";

Since the output of dmidecode is unlikely to change without hardware or BIOS setting changes, it might be optimal to cache dmidecode to a processed file within the ramfs and consult it instead.

I think this line was meant to initialize $star, it should come before line 145.
