I just used mdadm without doing any modprobe or insmod, to get it recognize the raid. So I assume the kernel 5.10.0-8 includes the driver (kernel 5.10.0-4 wasn’t working).
When I tried “mdadm --detail-platform” with 5.10.0-4 there was no raid controller detected, using 5.10.0-8 there is some output telling me on which Ports the hdd and ssd are attached.
