Hi, I was testing RAID 0 on my Dell Precision 3570 with Intel i7-1255U Alderlake processor. The mdadm tool did not work initially (the RAID was not recognised), but I was able to get the RAID working when I simply set IMSM_NO_PLATFORM=1. Then I tracked the issue down to UEFI variables and discovered that the platform newly uses the 'RstVmdV' name. This exactly same variable was used in recent patch series called "mdadm-CI for-jes/20220728", so I updated the code to recognise the new variable name also for VMD controller case. I then verified the change by first running it in a debugger and then by putting it to initrd on Fedora 36 (kernel 5.17). The startup was fine, the RAID 0 was correctly setup. I based my work on top of "mdadm-CI for-jes/20220728" patch series, it is required in order to apply the patch. Regards, Oldrich.
