Estou executando o kernel 6.12.10 e nas profundezas do meu log do dmesg, encontrei estas entradas:

kernel: ata4: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
kernel: ata4.00: Model 'INTEL SSDSCKJF360A5L', rev 'LT2i', applying quirks: zeroaftertrim
kernel: ata4.00: ACPI cmd f5/00:00:00:00:00:a0(SECURITY FREEZE LOCK) filtered out
kernel: ata4.00: supports DRM functions and may not be fully accessible

kernel:  sda: sda1 sda2 sda3 sda4 sda5 sda6
kernel: sd 3:0:0:0: [sda] Attached SCSI disk

O que significam as seguintes mensagens?

  • supports DRM functions and may not be fully accessible
  • read cache: enabled, doesn't support DPO or FUA

O que DRM significa neste contexto? (Duvido que signifique gerenciamento de direitos digitais.) Essas mensagens estão relacionadas?

Essas mensagens parecem ser novas. Não me lembro de tê-las visto antes. Mas não sei desde qual versão do kernel elas começaram a aparecer.
