IDE/ATA: Intel i865-based mainboard, CDROM not detected

IDE/ATA: Intel i865-based mainboard, CDROM not detected

[Jonathan Woithe]

A collegue of mine has an Intel mainboard with the i865 chipset onboard
(DQ965).  All kernels up to and including 2.6.22-rc2 do not detect the IDE
CDROM/DVDROM when booting.  The SATA hard drive is found without any
problems.

Relevant parts from lspci:

  00:1f.2 0101: 8086:2820 (rev 02)
  00:1f.2 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA
  IDE Controller (rev 02) (prog-if 8f [Master SecP SecO PriP PriO])
        Subsystem: Intel Corporation Unknown device 514d
        Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 19

  00:1f.5 0101: 8086:2825 (rev 02)
  00:1f.5 IDE interface: Intel Corporation 82801H (ICH8 Family) 2 port SATA
  IDE Controller (rev 02) (prog-if 85 [Master SecO PriO])
        Subsystem: Intel Corporation Unknown device 514d
        Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 19

What's interesting here is that 00:1f.2 and 00:1f.5 are both identified as
"n port SATA" controllers even though one of them (I suspect 00:1f.5) is a
PATA controller.  This may just be a typo in lspci's database though.

Here the HDD is clearly detected while the CDROM/DVDROM (attached to ide0)
isn't.

libata is compiled into the kernel as is the non-libata PATA driver.
In the libata configuration, only SATA_AHCI, ATA_PIIX and ATA_GENERIC are
defined.  For the non-libata side of things most options are selected
including BLK_DEV_IDE, BLK_DEV_IDECD, IDE_GENERIC, BLK_DEV_IDEPCI, 
BLK_DEV_GENERIC, BLK_DEV_IDEDMA_PCI and BLK_DEV_PIIX.

Does anyone have any ideas as to why there is a problem detecting the PATA
(IDE) CDROM/DVDROM in this machine?  Further information/testing can be
provided if requested.

Later ICH is listed by the documentation I have as SATA only. I would
imagine there is a seperate Jmicron or Marvell PATA controller on the
system ?

The CDROM was showing up in the POST in all cases.

It turns out the problem (as I outlined in a followup post) resulted from a
combination of issues.

 1) This board uses a Marvell PATA controller, so the relevant driver must
    be configured.

 2) Unless the "Configure SATA as" setting in the BIOS is set to "AHCI" the
    PATA controller won't be found.  Sounds a bit odd and counter-intuitive,
    but that's what's happening.  Originally this item was set to IDE; the
    other option is RAID but I haven't tested that.

Maybe the SATA pretending to be PATA took up the ports that the marvell
PATA needed to provide PATA, so in effect hidding the marvell.

I don't think so but I could be wrong.  When "Configure SATA as" was set to
"IDE" the HDD was being detected as a SATA drive and showed up as /dev/sda. 
The only visible difference the change to "AHCI" made was that instead of
the drive being handled by the ata_piix it now utilises the ahci driver
(which is a much better driver).  The other interesting thing is that the
probe for the Marvell PATA device occured before the initialisation of the
ata_piix driver (or ahci for that matter), so as far as I can tell ata_piix
had no chance to grab any ports before the marvell driver initialised.

Linux can still detect the chip and drive it natively even if the bios
is emulating IDE/PATA on the chip.  And libata will make both PATA and
SATA show up as /dev/sda now if you use libata for both.  On the other
hand if the bios has configured the intel chip to use the standard ide
registers, then it can't have configured the marvell to do so I would
guess, which could make it difficult to talk to.

Mostly true...  "standard IDE" can be configured in two modes, legacy 
mode and native mode.  Legacy mode has fixed addresses originating from 
the ISA days (0x170, 0x1f0, irqs 14 & 15), and (as you implied) you 
cannot bind two IDE controllers to the same ISA addresses.

OTOH, an unlimited number of IDE controllers can be configured into 
native mode, where all addresses and irq are allocated using standard 
means accorded all PCI devices.

In the situation being discussed, "ATA/IDE Mode" was set to "Native" in the
BIOS (the other option for this item was "Legacy").  The BIOS had a separate
"Configure SATA as" item with the options RAID, IDE and AHCI and it is this
one which, when set to IDE, prevented Linux from finding the Marvell PATA
chip - even though "ATA/IDE Mode" was set to "native".

The legacy/native issue Jeff discusses sounds like it relates to the
"ATA/IDE Mode" BIOS setting.  Since this was always "Native" during the
tests and given what Jeff wrote, I would have thought the BIOS would not be
using the legacy ISA-era settings and therefore they were not the reason for
Linux not finding the Marvell PATA controller.

A lot of newer Intel boards have the IDE interface provided by an 
external JMicron, etc. chip so you may need to enable that driver for 
things to work.

Also, it's unrelated to this problem, but you should check the BIOS 
settings for the SATA controller - you really want to get the controller 
into AHCI mode for best performance.

I've just tried a quick test after enabling most of the PATA drivers under
the libata section including the Jmicron driver (basically everything except
those labelled "highly experimental").  As far as I can tell the
CDROM/DVDROM is still not detected even with all these built into the
kernel.  Maybe I do need one of those "highly experimental" drivers.

I've often wondered how the BIOS descriptions correlate with the modes the
controller ends up in.  I've always gone for things like "enhanced" or
"SATA" or "native" (the exact string of course being dependent on the BIOS
writer's mood on the day).  This seems to work out OK in practice.  How
can you tell from the Linux boot messages that the controller is in AHCI
mode - is it as simple as looking for AHCI driver messages?  In this case
the 

  scsi0 : ata_piix
  scsi1 : ata_piix

indicate that things are suboptimal I assume.

Can you post the entire lspci -v for this board?

Right, you should see that showing up as ahci.

Does this apply to *all* SATA controllers or just these ICHx ones from
Intel?  In other words, should all optimally configured SATA controllers
be in AHCI mode?

Looks like you've got Marvell IDE for your PATA stuff (my board is the 
same).  Try the latest Marvell driver, it seems to drive my machine ok.  
For older kernels, I think you can pass 'all-generic-ide' on the boot 
line to get the old IDE layer to drive the device.

This would be your PATA port - pata_marvell.

If they have an AHCI mode then currently yes. AHCI is a well designed
interface with nice functionality. None of the devices which support
multiple modes of operation have any custom mode that is nicer .. so far
anyway.

Oh dear, would you believe I totally missed this entry in a dozen runs
though the output yesterday?  A fresh pair of eyes always helps.

Are we talking CONFIG_PATA_MARVELL here?  If so then the kernel I just
booted has this set to "y" (ie: built-in) and yet the drive is still not
detected.  Is there a newer version of this driver somewhere?  The kernel
was 2.6.22-rc2.

Should be current. Its known to work fine for that chip so you might need
to do some debugging and provide more detail.

I got someone to go into the BIOS setup (I am debugging this remotely) and
check the IDE/ATA related options.  The two relevant options were set
as follows:

  ATA/IDE Mode: <Native>    [ Choices: Legacy, Native ]
  Configure SATA as: <IDE>  [ Choices: IDE, RAID, AHCI ]

I had them change the "Configure SATA as" setting from "IDE" to "AHCI"
and then reboot into 2.6.22-rc2.  At this point things appear to be much
happier:

Therefore it seems that for whatever reason, the marvell_pata driver will
only find the Marvell PATA IDE controller if the *SATA* mode in the BIOS is
set to "AHCI".  It's somewhat counter-intuitive, but since AHCI is the
"correct" setting for SATA performance reasons it's probably not such a bad
thing.

So, thanks for all the suggestions; the problem appears solved.

Hi,

just curious, what makes you think that AHCI is better wrt performance?

NCQ support, CPU cycle savings, no silly DMA limits (supports larger 
clustered chunks of data, less bouncing), supports 64-bit (no bouncing 
on 64-bit), eliminates use of PIO, the list goes on.
