NEW features of cdrecord-1.9a03:
We are now only a few releases away from the final libscg that includes
SCSI low level command transport.
All:
- scsitransp.c split into scsitransp.c and scsi-sun.c
- Fallback code to use the USCSI interface on Solaris
This should add ATAPI support on Solaris 8 sparc.
Solaris 8 x86 does support ATAPI with the scg driver
as Sun fixed the structural bug for thw Intel version.
Warning: The USCI interface has several drawbacks:
- Only finds disk type devices with -scanbus
- Cannot open devices that are currently attached
to the volume management system
- The Goldstar ATAPI CD-ROM in a U-10 transfers data
but the DMA residual count shows that there has
been no transfer at all.
Facit: Test by your own if this interface is usable.
Please report problems!
To check the difference:
cdrecord -scanbus uses the scg driver
cdrecord -scanbus dev=USCSI uses the USCSI interface
cdrecord -toc dev=1,6,0 uses the scg driver
cdrecord -toc dev=USCSI:1,6,0 uses the USCSI interface
- Better error mesages for SCSI open in libscg
- Linux code in libscg now tries to use new features of the
Linus sg driver:
- Trying to use more then 32 kB for DMA
The interface for raising the DMA limit from 32 kB
is a real pain. It needs a lot of code to adopt
the interface to libscg.
- Trying to use the new ioctl() interface if present.
This interface now supports:
- SCSI CDB sizes for vendor unique commands
- SCSI status byte
- SCSI command transport status
- More than 16 bytes of sense data
(not yet working!)
- DMA residual count
(not yet working!)
- Arbitrary DMA address pointers !!!
- Trying to use the new RESET ioctl()
(not yet working!)
All items marked (not yet working!) will turn funtional
after the Linux kernel starts to support them.
It seems that my shouting for a better SCSI interface succeeded.
Linux-2.4 supports or at least includes an interface that may support
the needed things in future.
As from now it is unclear whether the code will expose
any portability problems, please test on different Linux
versions from 2.0 ... 2.4 if available and report problems.
TODO:
- Better BeOS integration
Cdrecord:
- New manufacturer "Bestdisc Technology Corporation"
in disk decoder.
- ATIP Decoder now decodes disk sub type for High speed CD-RW
- Firt support for 99 minute CD's.
Cdda2wav:
- more diagnostics for illegal ISRCs
- use setpriority in favor of nice
- updated cdda2mp3 script for lame usage (alpha)
Readcd:
- restructured to be more flexible
- Support for C2 error pointer scan with MMC drives &
the Plextor U-Plex 40 CD-ROM
Mkisofs:
- Allow printing of percentage ready without floatingpoint code
in printf.
- apple_driver now compiles, but need to call
make -f apple_driver.mk
by hand
- graft pointers are now really usable:
- Graft points are now disabled by default
- To enable, specify the -graft-point option
dir=dir only works if the '=' is not escaped by '\'
'\\' and '=' must be escaped by a '\\' if
-graft-points has been specified.
