[gentoo-user] dd if=/dev/dvd of=backup.iso - DMA related problem

[gentoo-user] dd if=/dev/dvd of=backup.iso - DMA related problem

[Joseph]

A week ago I was posted a message when struggling trying to copy my
own DVD with:
dd if=/dev/dvd of=backup.iso  or
cat /dev/dvd >backup.iso

After following several leads from Gentoo folks (including replacing DVD
cable) I've narrow it down to problem with "dma" resetting itself on
"eject". 

When I boot the computer (amd64) the DVD DMA is "ON" 
[quote]using_dma = 1 (on) 

At this point I can make as many copies as I want using commands "dd" or
"cat" but I can not issue eject command 
eject /dev/hdc

As soon as I eject the CD (and reinsert it) the status of DMA is
changing on the DVD 
using_dma = 0 (off) 
And at this point make no difference if I change that status back to
"ON" or not every subsequent DVD copy fails.

I've run onto few posting on Google regarding DMA resetting itself but
no solution.

That is simply annoying, that the Linux-Kernel resets DMA.

You could try "hdparm -k1" - but somethimes that doesn't help either.

Yes, I've tried "-k1" too, it doesn't help.
It seems like kernel bug, I was able to duplicate resetting CD/DVD DMA
on both machines:
amd64 with BenQ DVD writer and
x86 with Plextor CD writer

It might be a bug, though it probably is only for certain drives.  I
have a LITE-ON DVDRW LDW-451S on amd64.  Here is a test I just ran:


jim@keelie $ sudo hdparm /dev/hdc
/dev/hdc:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

jim@keelie $ sudo eject

jim@keelie $ sudo hdparm /dev/hdc
/dev/hdc:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

jim@keelie $ sudo eject

jim@keelie $ sudo hdparm /dev/hdc
/dev/hdc:
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 HDIO_GETGEO failed: Invalid argument

jim@keelie $ eject  --version
eject version 2.1.0 by Jeff Tranter (tranter@pobox.com)

Running eject as root or a regular user did not reset my DMA
settings for my DVD-RW.

Before ejecting put any CD / DVD disk IN and run:
dd if=/dev/hdc of=backup.iso  or
cat /dev/hdc >backup.iso

When finished run "eject ..." 
and 
hdparm /dev/hdc

See if the parameter "using_dma" was reset.

DMA is still on.  I don't know why I always get that "HDIO_GETGEO
failed" error.

Do you have another CD/DVD drive you can try?  Are you using SCSI
emulation?

I am using kernel 2.6.15-gentoo-r7

Did you do "eject /dev/hdc between dd and hdparm?

dd if=/dev/hdc of=backup.iso
eject dev/hdc
hdparm /dev/hdc

Yes, I've tried this combination on two different machines with two
different drives and DMA gests rest on both.
amd64 + BenQ DVD
x86 + Plexwriter

I'm using kernel 2.6-15

Hmm, what type of controller is this attached to?

On my new laptop, I have a PATA DVD burner, but it is ultimately
attached to a SATA chipset.  I could not get DMA to work correctly
using the IDE drivers.  The solution was to disable all IDE support,
add SCSI CD-ROM support, and let the SATA driver control the drive as
/dev/sr0.

That is interesting. 
My DVD burner is connected to IDE controller and I have in kernel
enabled both options support:
<*> Include IDE/ATAPI CDROM support
and
<*> SCSI CDROM support
My DVD is recognized as /dev/hdc 

If I disable first option "DE/ATAPI CDROM support" will the drive be
recognized as /dev/sr0 ???

No, you would need to disable (or at least modularize) all IDE/ATAPI
support (# CONFIG_IDE is not set).

But this would _only_ be an option if you actually have a SATA
chipset.  If it is truly a PATA controller, then you won't get
/dev/sr0 no matter what you do. [1]

Maybe you can post your dmesg output?

-Richard

[1] Technically you could use ide-scsi emulation, but it wouldn't help.

OK, here is dmesg output, the last two lines indicate that:
hdc: DMA disabled
hdc: ATAPI reset complete

What application reseted the DMA, I don't know?

The lines that are interesting to me are:

VP_IDE: IDE controller at PCI slot 0000:00:0f.1
sata_via 0000:00:0f.0: version 1.1

The above PCI id lines indicate that your parallel ata (IDE) device is
really just a function of your SATA chip.  Since your hard disk
wouldn't be affected, I would try a kernel without IDE support and see
if the SATA driver picks up your CD drive.

I've disable IDE ATAPI CD-ROM in the kernel but the DVD-drive wasn't
recognized upon reboot; well I think I just have to wait till they fix
it in the kernel :-/
For now, every time I made copy and eject the CD, I will reboot the
computer; oh well it is like Windows 98 - I'm used to it :-)

Did you try to turn off all SCSI cdrom options?  Make sure SCSI CDROM
support is off as well as SCSI CDROM emulation.

Are you using a genkernel?  I recompiled my kernel to have the main
stuff in the kernel.  For example SATA, IDE CD, ext2, reiserfs, etc is
compiled into the kernel instead of as modules.

Did try to boot with this kernel option:
pci=usepirqmask

I've tried disabling SCSI for IDE and SCSI CDROM but I can not find any
"sr"  recognized devices; unless I missed something.
I've added to grub.conf as well (default kernel): 
root=/dev/sda3 pci=noacpi noapci pci=usepirqmask
it didn't help.

Here is what i have enabled in kernel when it comes to SCSI:
