Look at the portion of your dmesg where AHCI is loaded: You'll see some lines like this: [3675853.416077] ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo p= mp pio slum part ems=20 [3675855.666834] ahci 0000:04:00.0: flags: 64bit stag led slum part=20 Relevant lspci bits: 00:1f.2 SATA controller: Intel Corporation 82801JI (ICH10 Family) SATA AHCI= Controller 04:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6121 SATA II Contr= oller (rev b1) Notice the 'pmp' flag on the first one. From what I understand, the AHCI BIOS portions can choose to enable or disable things like PMP support, and that's why it's reflected in the inquiry data.
