SATA PMP issue

SATA PMP issue

[DeadManMoving]

Hi Mister Heo and list,

i am unable to get SATA port multiplier to work between a Marvell SATA
88SE9120 CARD (HighPoint Rocket 622A) and four disks within a Mediasonic
HF2-SU3S2 enclosure.

Howerver, the Mediasonic enclosure is working with a SiI 3132 controller
(i can see all four disks) and also, i have a Thermaltake BlacX Duet
which is working on the 88SE9120 (i can see both disks).

Here is what the kernel have to say when i try to get the 88SE9120 to
work with the Mediasonic enclosure :

I have tried with :

modprobe ahci marvell_enable=1

but does not look to work neither.

I am running vanilla 3.11.0-rc4 from kernel.org

I saw a comment from you on this list
(http://marc.info/?l=linux-ide&m=131434190330255&w=2) stating that the
controller must be in wrong state if the kernel is reporting "Port
Multiplier vendor mismatch" error message but, the controller seem fine
since it is working with the Thermaltake BlacX Duet enclosure.

Unfortunately, I kinda gave up on PMP / controller compatibility
issues and it seems like most vendors have given up on PMPs too.
After the first gen chips, nobody is really working on it, and the
first gen chips of course are full of quirks and bugs.  At this point,
I'd generally recommend against using PMPs and if you really want to
stick to known working configurations.

Sorry.

Hi Mister Heo,

first, thank you so much to have taken the time to answer.

I sure can understand your point, i have spent some time too see what
was supported and what was not and finally, i have equipments that looks
like are not working together.

But on the other hand, it is not easy to try to stick to known working
configurations since, from what i have seen, the chip inside enclosures
are rarely exposed to consumer.

It will probably changes nothing but, i am pretty sure now that this is
not an hardware incompatibility since, i have spent some time yesterday,
doing a FreeBSD install on a spare disk, in one of my computer with the
Marvell 88SE9120 controller and, when i hooked up the Mediasonic
enclosure (which, i finally found out is using a JMicron JMB393 chip
(0x197b:0x0325)), i was able to see all four drives without any issue
(with the FreeBSD ahci driver of course).


Best regards,

Tony
