 Posted: Thu Jul 11, 2013 10:25 am Post subject: Sony DVD drive not recognized |
 |
|
Must be at least a year ago now, I suppose I upgraded software on my wife's machine, and the DVD drive stopped being recognized. I have banged my head against this problem on and off for months now, and have not managed to solve it. The device is a Sony DDU1615.
I know the silly thing works, because I can boot a live distro off of it, and if I do an lsscsi in the live OS, the optical drive shows up, but it does not show up for the normal Gentoo install. It does show up in my Gentoo dmesg like this: | Code: | $ dmesg | grep -i dvd
[ 0.503320] ata1.00: ATAPI: SONY DVD-ROM DDU1615, FYS1, max UDMA/33
|
Without trying to repeat here all of the many twistings and turnings I've been through...... I must assume based on the evidence that I am simply missing the driver in my kernel config, but I have turned on many things, to no avail. I'm guessing the one I need is one of the ones under CONFIG_ATA_BMDMA. I found a few threads here in the forum mentioning the device model number, but none of that module advice has helped.
I have googled and surfed - done my due diligence - but cannot find the info I need. How do I find out the chipset that this thing uses, or better, the kernel module that I need to turn on?? (if googling doesn't reveal it). Is there some way I can make the live Linux OS tell me the kernel driver it's using? I "lost" one kernel setting a year ago and have been paying for it ever since!
Thanks for any advice. |

Is the snippit of interest.
Since your HDD works, we know you have both
<*> SCSI disk support and <*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support in your kernel. So far so good.
CDROM support also needs <*> SCSI CDROM support, maybe [ ] Enable vendor-specific extensions (for SCSI CDROM).
While you are poking about, <*> SCSI generic support and [*] Probe all LUNs on each SCSI device are both a good idea.
Your cdrom will be /dev/sr0 ... udev no longer makes all the symlinks to it.

Why isn't this set to the standard value (that is AHCI) ? |

VoidMage,
Well caught!
Punchcutter,
To switch to AHCI mode, add the AHCI driver to your kernel then go into the BIOS and switch your IDE controller out of compatibility mode.
IDE mode on AHCI controllers was intended to be used once only by Windows users to enable them to install the AHCI driver before they switched away from it forever.
As a one time thing, IDe mode functionality is often incomplete. DMA support is missing on some chipsets, so its slow, often, only four ports are supported, so if you have six ports you can only use the first four while in IDE mode.
This can be a problem if your CD is connected to port five or six.

Thanks a lot, guys... wow. So, now I have this: | Code: | # lsmod | grep ahci
ahci 18220 0
libahci 14013 1 ahci
# zgrep -i ahci /proc/config.gz
CONFIG_SATA_AHCI=m
CONFIG_SATA_AHCI_PLATFORM=m
# CONFIG_SATA_ACARD_AHCI is not set
|
and still no /dev/sr0, so I look to the BIOS. I'm not sure exactly where "IDE compatibility mode" is, so I've made a schematic of the choices available in the BIOS (leaving out ones that seemed completely irrelevant to me, and with selected options *'ed): | Code: | Device Configuration
CD-ROM IDE Primary 0 ->
Transfer mode: Max UDMA* / PIO 0 / Max PIO / Enhanced DMA / Ultra DMA 0
Default Values
IDE/SATA ->
Multisector transfer: 16* / 8 / disable
Transfer mode: <as above>
Translation mode: Auto* / Bit Shift / LBA assisted / User (with more settings) / Off
Storage Options
BIOS DMA transfers: Enable
SATA Emulation: *Separate IDE Controller / Combined IDE Controller
IDE Controller: Enable
Primary SATA Controller: Enable
Secondary SATA Controller: Enable
|
Can you point me to the BIOS change I need? I should point out, of course, that this drive used to work, with the BIOS settings as they are, but I gather the change is needed because of a change to AHCI from whatever was the kernel config before, eh?
Thanks again. |

Punchcutter,
| Code: | | SATA Emulation: *Separate IDE Controller / Combined IDE Controller |
is about the only one you should try to change.
Your lspci says
| Code: | 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01)
00:1f.2 IDE interface: Intel Corporation NM10/ICH7 Family SATA Controller [IDE mode] (rev 01) |
thats two functions on one device.
When its right, the [IDE mode] in 00:1f.2 IDE interface: Intel Corporation NM10/ICH7 Family SATA Controller [IDE mode] (rev 01) will change.

Well, I tried changing the SATA emulation, and also its associated sub-settings, putting them in all the different possible arrangements of enabled/disabled, but..... still no sign of /dev/sr0 
I haven't tried opening the case to see if something I see inside gives me a clue. Maybe that's the next step. Could the solution to this possibly be related to the jumpering of the device?
Let me throw one more thing out that I had forgotten: when I boot from my live distro, I see a module scsi_mod listed, and it is "linked" (I don't know how to express it when modules are listed side-by-side in lsmod  ) with sr_mod. On my wife's installed OS, sr_mod is loaded, and I've got a CONFIG_SCSI_MOD=y, but if I look for this in menuconfig, I see nothing other than the name, basically, i.e. no pointer to where this setting is located within the kernel menus, or indication as to what it IS, what it might depend on, etc. This worries me just because it is a mystery  |

Punchcutter,
Heres a sample from my lsmod
| Code: | Module Size Used by
snd_hda_codec 113662 2 snd_hda_codec_via,snd_hda_intel |
The list off to the right is a list of modules using the module named in the left column.
Modules are also listed in lsmod in load order, with the first loaded module being at the bottom of the list. Load order can be important.
| Punchcutter wrote: | | On my wife's installed OS, sr_mod is loaded, and I've got a CONFIG_SCSI_MOD=y |
<M> SCSI CDROM support provides the module sr_mod
CONFIG_SCSI_MOD is a hidden symbol in the .config file, I don't know what it does or what selects it. I have CONFIG_SCSI_MOD=y too
