Promise 20378

Promise 20378

So, there doesn't appear to be a driver for the 20378 in the kernel...
though google showed a few people using some proprietary drivers with
varying luck. Ew.

I noticed there are a lot of other Promise drivers in the kernel for the
same general line, which leads me to believe there may be some interest
in getting a 20378 driver in the kernel.

So, since I now own a machine with one, I thought I'd drop this list a
line and say "I can test stuff and provide info on the chipset"...

Specifically, I have a:

0000:02:04.0 RAID bus controller: Promise Technology, Inc. PDC20378

Anyway, I don't know if that's any help, or if there is any interest,
but I thought I'd throw it out there.

PS, I'm not on the list, so please CC me on replies.

Thanks,

Just add the PCI ID to drivers/scsi/sata_promise.c...

Markus K. emailed me to let me know about sata_promise, which already
binds to my controller with no errors. I'm wondering if it'll support
the PATA controller on there as well - we'll see. I'll play around with
it and report back. Thanks.

I finally got a chance to test this.

So, the sata_promise driver seems to support the Promise 20378
controller, but it doesn't see PATA drives (the controller supports both
SATA and PATA drives).

I plugged a single PATA drive in - then in the promise BIOS I configured
a single "array" on the drive, and booted. This sata_promise sees the
PATA and SATA controller, but doesn't see the drives:

Jul 23 13:31:47 rider kernel: ata1: SATA max UDMA/133 cmd 0xF89E4200 ctl
0xF89E4238 bmdma 0x0 irq 23
Jul 23 13:31:47 rider kernel: ata2: SATA max UDMA/133 cmd 0xF89E4280 ctl
0xF89E42B8 bmdma 0x0 irq 23
Jul 23 13:31:47 rider kernel: ata1: no device found (phy stat 00000000)
Jul 23 13:31:47 rider kernel: scsi0 : sata_promise
Jul 23 13:31:47 rider kernel: ata2: no device found (phy stat 00000000)
Jul 23 13:31:47 rider kernel: scsi1 : sata_promise

It sees no drives there period. Further, while it the device has 2 SATA
chains, it only has 1 PATA, but as you can see, it seems to see 2.

Any ideas?

I never did get a response to this - is this the known status (if so,
that's fine I have a work around, but if I'm doing something stupid, i'd
also like to know so I can start using this)...

Thanks.

Re: Promise 20378

Phil, there is a patch in Jeff Garzik's libata-dev patch queue to support PATA
on Promise SATA hosts. I haven't tried it out myself, but it may cover your
case.

Go to http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/ and grab the
latest patch for 2.4 or 2.6. If you grab 2.6.13-rc7-libata1.patch.bz2, it
applies cleanly to 2.6.13.

Please report back the results!

Best regards,
Matt

Finally got around to trying this. It works great! I patched 2.6.15.6
with this patch, and everything seems to be fully functional as far as
the PATA drive on that controller is concerned.

However, a few concerns:

1. The kernel raid autodetection doesn't work here. Though I'm not clear
if it supports going across controllers. I set up a raid-1 array wtih a
drive on my other controller, set the partition type to autodetect, but
a reboot left my array with just the drive not on the promise card.

2. Currently my BIOS's ATA settings are "SATA mode" - I also have "PATA
mode" "SATA+PATA mode". I tried SATA+PATA and I get a bunch of IRQ16
ignored messages, a few tracebacks, and a LOT of slowness. I also get 3
scsiI haven't tried the PATA mode.

Note that my box has 82801EB/ER controller which is currently my primary
contoller as well as the Promise PDC20378 which is what I'm using this
patch for.

Any help would be appreciated.

I never saw a response to my email below. Any thoughts on this? Thanks.
