Dear Tejun/All, EDIT: sorry, the first email sent as html, now this is a clean txt version of it. Sorry again. ---- I checked the ahci.c after I failed to use Asmedia sata card (pci:1b21- 0624-1b21-1060;01-01-85;detected;storage;pata_acpi;ASMedia Technology Inc.;IDE interface;ASMedia Technology Inc.) in linux, using kernel 5.11.0-37-lowlatency. As I found no answer/solution on the net, as a final resort I write to you about this card and try to ask you to look after this chip. Technically this pci sata card is a 10 ports card, using (as I can see) 3 chips in cascade to get 2x5 sata ports. Regarding to the recent Asmedia support, I found this: https://github.com/torvalds/linux/blob/master/drivers/ata/ahci.c#L588 /* Asmedia */ { PCI_VDEVICE(ASMEDIA, 0x0601), board_ahci }, /* ASM1060 */ { PCI_VDEVICE(ASMEDIA, 0x0602), board_ahci }, /* ASM1060 */ { PCI_VDEVICE(ASMEDIA, 0x0611), board_ahci }, /* ASM1061 */ { PCI_VDEVICE(ASMEDIA, 0x0612), board_ahci }, /* ASM1062 */ { PCI_VDEVICE(ASMEDIA, 0x0621), board_ahci }, /* ASM1061R */ { PCI_VDEVICE(ASMEDIA, 0x0622), board_ahci }, /* ASM1062R */ So, unfortunately the 0624 is not there yet. Thank you all for your time an efforts regarding the development! Best regards, Mr. István Pongrácz
