How about finally adding UEFI memtest (v5+) to manjaro?
Starting from MemTest86 v5, the code was re-written to support self-booting from the newer UEFI platform. The software still remains free to use without restrictions. The MemTest86 v4 project is still maintained and remains open source, for use on old machines with BIOS. However, from V5 with the latest release being V8.3 the software is being released under a proprietary license. Development on the MemTest86+ version seems to be discontinued as there have been no updates since 2013.
Yes I know… PassMark version has proprietary license
but there is some action also in https://www.memtest.org/ after 7 years. 5.31b is being worked on
