Dear Tejun/All,

I just downloaded the ubuntu kernel source version 5.4.140 and I
modified the ahci.c file:

I simply added the extra line with the pci id of the card as shown
below:
 
	/* 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 */
+ 	{ PCI_VDEVICE(ASMEDIA, 0x0624), board_ahci }, 

Similarly to the other entries above your addition, please add a comment at the
end of the line mentioning the adapter model.

I built the kernel and rebooted the machine.
Now the kernel can see disks attached to the card.
As I just drop some hdds I had around, it seems I got some non-working
hdds, so, I will have to get some proven working hdds to populate all
the 10 sata channels and test them.

Summary: at this point it seems with the modification above this card
could work.

If you need something I should do (test), please let me know, I would
be happy to participate in this test.

Looks like you're on the right path. Once you're happy with the result, can
you please submit the above as a signed-off patch?

Thank you.

Hi,

An update about my test, short version:
- I had to change my power supply to be able to feed all hdds
- I have 2 pieces of 10 sata ports cards + motherboard 2
- I installed win10 + asmedia driver provided with the card on a mini
CD -> working.
- I installed linuxmint 20.2 Mate and kernel source 5.4.140
- I added the extra line to the ahci.c as shown above and compiled the
kernel, installed etc.
- with the new kernel, the system started and recognised all the hdds
attached to the cards (2x7 HDDs)

My result after about 24 hours of running, these cards are working
well.

Only one small thing I found, besides of ahci, pata_acpi still visible
 as used kernel modules under the card.
I have no idea, is it ok or not or how to remove pata_acpi if
necessary.

Anyway, I did not find any side effects up to now. 
s.m.a.r.t. is working, ssd/hdd recognised, I already use it with about
13TByte live data (so, software uses these data files on disks without
problem etc.).

So far so good.

@Tejun, I am not a kernel developer, so, not really clear where to send
the "patch" and for which kernel version :)

write your patch against the latest libata tree available at:

git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata.git

or

https://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata.git

And use "git send-email" to send the patch to me and to linux-ide@vger.kernel.org.

Feel free to let me know if you have any problem.

Thanks.
