A first release of cdrecord has been released for AIX.
AIX has a userland SCSI ioctl(2) but unfortunately no SCSI userland device
node interface.
This cdrecord distribution contains a hacked mkisofs-1.12.1 that runs on AIX
and allows you to read a filesystem from a CD-R device with 2048 bytes
if AIX does not support 2048 Bytes/sector (I don' know). This is done
with the SCSI user level library.
The current implementation status is alpha. It currently only handles
/dev/rcd* devices. No real generic SCSI support.
I got a donation from
Michael Staats <michael@thp.Uni-Duisburg.DE>
& Fred Hucht <fred@thp.Uni-Duisburg.DE>
that I hope to integrate in the near future.
To make a decent release, I need access to a recent AIX
system. I currently only have non-root access to an old system without man
pages, so I cannot test. To include error handling, I need to know some things
abount what is happening on special error situations.
To compile with the AIX cc use ./Gmake or smake from my makefiles
distribution.
To compile with the AIX cc use ./Gmake CCOM=gcc or smake CCOM=gcc
from my makefiles distribution.
NOTE: AIX seems to have a kernel bug in the mmap() part
that may cause kernel panics.
If you observe this kernel panic, try to add a line:
COPTS += -DUSE_USGSHM
to the file cdrecord/Makefile
or compile the package using:
make COPTX=-DUSE_USGSHM
It seems that SVrx style shared memory does not have this kernel bug
I would be happy to get test reports ...
