UDF packet writing w. ide cdrw and 2.6 test11

[gniWkraD]

I've been trying to get UDF packet writing to work with the 2.6 test11 kernel, but pktsetup won't work. My cdrw is an IDE device on hdd.
Here is what I do:

1) compiled 2.6test11 kernel with UDF and SCSI support.
(there is only one option for UDF, nothing about read or write)

2) after successfull reboot w 2.6 test11: 'emerge udftools'

3) now i can format a UDF cdrw with ' cdrwtool -d /dev/cdroms/cdrom1 -q -t4'
-witch took about 20mins with no errors. After the formatting I can mount the disc with:
'mount -t udf /dev/cdroms/cdrom1 /mnt/cdrom -o rw,noatime' witch gives me a warning about the disc beeing writeprotected,
but otherwise works fine and lets me browse the cd.
(I also tried 'chmod 777 /mnt/cdrom', but i says the disc i write protected)


4) After unmounting the drive I tried to follow the instructions from
http://cvs.linuxfromscratch.org/index.cgi/hints/Attic/cdrw-hint.txt?rev=1.3
so I did the following:

5) 'mknod /dev/pktcdvd0 b 97 0'

6) 'chmod 666 /dev/pktcdvd0'

7) 'pktsetup /dev/pktcdvd0 /dev/cdroms/cdrom1'
Here it fails, I get the error message:
'open packet device: No such device or address'
even though I can verify that both the link to the cdrw and pktcdvd0 block device exists.

Has anybody made this work with an IDE device ? (all the examples are with a scsi device on e.g /dev/sr0)

Ok problem solved...
There is a nice mailing list at
http://lists.suse.com/archive/packet-writing
where the maintainers also hang out

Even though packet writing afaik will be a built in feature of kernel 2.6, test11 needs to be patched to make it work.
The patch can found here:
http://w1.894.telia.com/~u89404340/patches/packet/2.5/

1) copy the patch to /usr/src (dont unpack it) and cd to /usr/src/linux

2) asuming that /usr/src/linux points to kernel 2.6test11apply the patch with the folowing command:

Hei gniWkraD

I'm able to read/play music from Win produced InCD-type dvd's, and would like now to get packet writing to work too on development-sources 2.6.7-rc3.

Am I right in thinking the patch you mention would not apply to that version?

jep you need the specific patch for your kernel version

Patches for various kernel versions can be found here:
http://w1.894.telia.com/~u89404340/patches/packet/

It seems that there isnt a patch for 2.6.7 yet, but there are usually out pretty quick.

Cheers!

Thanks, guess I'll have to be patient

BTW, the 2.6.6 patch patches perfectly onto gentoo-dev-sources 2.6.7-r6.

Thanks Jdong

I installed the packet-patch for CD-RW on development-sources 2.6.6 OK, but I'm using development-sources 2.6.7 now, and am really waiting for udf for dvd+rw.. so I can drag & drop files to dvd (as with InCD )

I've patched 2.6.7-ck2 and everything works just fine except I can't write to the disk as non-root. I can mount it as a normal user but here's the mount point permissions after mounting: drwxr-xr-x 4 root root 1080 Jun 29 17:14 cdrw
As root I can write though. Here's my fstab:
