Use the SCSI SG_IO ioctl() with opcode=ATA_16, which gives you access to the ATA Passthrough mechanism. This will work for most ATA commands.
How about soft-reset, is it possible to reach Device Control Register ? Seems not. I was thinking about patch to libata which allow to use Control Register. In the perfect case i would like to be able to execute vendor command set (reverse engineered). Is it possible to control timeouts in user space precisely enough and get rid of unnecessary kernel error messages without touching syslogd/klogd? By the way, how to make libata to not probe some ide channel or drive ?
I already use it in hdparm and in some other utilities for scanning/repairing drives. A notable exeception are the READ/WRITE LONG opcodes, which require an extra kernel patch from me, awaiting merge into libata some year.
Could you please send me this patch once it's ready ? Thank you - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
