| |
Sorry, if this issue was already discussed in lkml. I didn't find a reference to this at www.geocrawler.com
My Problem: I want to set the unmaskirq and dma -flag for my ide cd-recorder. The Problem is, that devfs creates no ide device, but only the /dev/scsi/../{cd,general} devices are created. And hdparm don't accepts this devices for setting the ide-parameters.
My current workaround is to create a /dev/hd? device "by hand" at system startup. This is not very beautiful. Furthermore, if the device numbers in devfs are deactivated, this won't work anymore.
I can live with my current solution. But i would be very happy if someone can present a clean solution.
I posted this message intentionally not on the devfs mailing list as i think this problem is related to accessing the same device through different /dev entries. Under devfs, the /dev/ide/... device node gets allocated after the corresponding ide-xx.o has been loaded. But this is not possible with ide-scsi claiming the device :(
Thanks in advance
