JMicron JMB363 PCI SATA/IDE Card Support

[Matthias Prager]

Hello everyone,

I'm having a hard time getting my JMicron JMB363 PCI SATA/IDE Card
to work under linux.

RAID bus controller [0104]: JMicron Technology Corp. JMB363 SATA/IDE
Controller [197b:2363] (rev 03)

I tried my own kernel (3.9.6) under gentoo with CONFIG_PATA_JMICRON and
CONFIG_SATA_AHCI enabled. And I tried using
the latest SystemrescueCD (with kernel 3.4.47) which has pretty much
everything compiled into it.

FreeBSD is recognizing the devices just fine. How do I get them
to run on linux?

- Matthias

P.S. a side note: this is in an virtualized environment (VMWare ESXi)
with pass-through.

I did some more digging and came up with a partial

{ PCI_VDEVICE(JMICRON, 0x236f), board_ahci_ign_iferr },

(at line 301 of drivers/ata/ahci.c)
The the sata ports of my two cards get detected and lspci -k shows
they are using the ahci driver.

My guess is the 'RAID bus controller [0104]' mode/class is keeping
my cards from beeing detected (they probably would be if they were
in PCI_CLASS_STORAGE_SATA_AHCI mode). Which would mean line 297
is just plain buggy.

This still leaves the problem of the missing IDE Ports (one master+slave
port per card are still not detected). I'm trying to
understand how the pata_jmicron driver is supposed to work
but haven't wrapped my head around it yet.

Looks like the RAID Mode is the default one and
quirk_jmicron_ata() in drivers/pci/quirks.c is supposed
to deal with it by changing the PCI device configuration ...
this does not happen or does not have the desired
result (maybe this is caused by working in a pass-trough
environment?).
