What does "supports DRM functions and may not be fully accessible" mean for SATA SDDs?

I am running kernel 6.12.10 and in the depth of my dmesg log, I found those entries:

kernel: ata4: SATA link up 6.0 Gbps (SStatus 133 SControl 300)

What do the following messages mean? * supports DRM functions and may not be fully accessible * read cache: enabled, doesn't support DPO or FUA What does DRM stand for in this context? (I doubt it means digital rights management.) Are those messages related? These messages seem to be new. I cannot remember to have seen them previously. But I don't know since which kernel version they have started to appear.
