Re: [discuss] ide=reverse do we still need this?

The only bother I've found so far is the pci_get_device_reverse() function, it's used in 2 places, IDE and the calgary driver. I'm curious if we really still support the ide=reverse option? It's a config option that I don't think the distros still enable (SuSE does not). Is this still needed these days? In digging, we changed this option in 2.2.x from being called pci=reverse and no one else seems to miss it. Any thoughts? I remember vaguely that some years ago, we set up a box with four IDE disks as a RAID set. For that purpose, we added a PCI ATA100 controller so that each disk could act as a primary IDE device and we were only able to boot the system with the option ide=reverse. That box has been replaced by some other so I cannot verify it but as far as I remember it was a problem with disk numbering between BIOS, bootloader and/or kernel. Also, at that time we used lilo and I am not sure if grub would have done better. Hm, so, to summarize: - you needed this option many years ago to get a box to work properly - you don't need this today So, if the option went away, you would not be inconvenienced? thanks, greg k-h - To unsubscribe from this list: send the line unsubscribe linux-ide in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

I remember that the disks of the old box are still in a drawer and today, I will try to reanimate the system and see if grub's ability to map drives helps to boot the system without ide=reverse. I'll report later.

After having reanimated the old system and after comments of other persons I would not be inconvenienced if the option went away. The system indeed did not boot correctly without that option, because the disks appeared in a wrong order. On the other hand, I was able to (re)install bootloaders (grub as well as lilo) and after that did not need the option any more. Unfortunately, after that I was not able to reproduce the initial situation where the option was needed.

Great, thanks a lot for testing this, and letting us know. greg k-h - To unsubscribe from this list: send the line unsubscribe linux-ide in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
