[Bug 217372] New: hot-plugged IDE CDROM is not detected (FATE ID 300648)
https://bugzilla.novell.com/show_bug.cgi?id=217372 Summary: hot-plugged IDE CDROM is not detected (FATE ID 300648) Product: openSUSE 10.2 Version: Beta 1 plus Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: seife@novell.com QAContact: qa@suse.de OtherBugsDependingO 215208 nThis: Test Case 137494 - Support IDE Hotplug for Laptops (FATE ID 300648) I booted the compaq nx5000 (1st generation centrino notebook, piix driver for hdd and cdrom) without the cdrom inserted, then inserted the CDROM. The device was not recognized at all, /dev/hdc was not created and i was not able to access it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The Feature in FATE300648 simply is not implemented, although fate states that it is. Just assign to PM. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=217372 ------- Comment #6 from hare@novell.com 2006-11-06 04:48 MST ------- Again, this only works when using the libata driver (ie ata_piix). The original IDE driver (piix) will not support this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=217372 ------- Comment #7 from seife@novell.com 2006-11-06 06:02 MST ------- Might be. We are, however, not using the libata driver as default -> FATE not implemented? Also, the last time i tried to use libata (Beta1+), it was unusably slow, so i can only try this with beta2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

If IDE refers to the hardware, then this feature is supported & implemented by using the libata drivers. If IDE refers to the drivers, then this feature should be rejected as we cannot implement this in the 10.2 timeframe. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=217372 ------- Comment #9 from seife@novell.com 2006-11-07 03:22 MST ------- i read the FATE that it should "just work". To make it "just work", we need more than just kernel support: - we need a "securely remove hardware" applet / infrastructure - we need a "add hardware" applet / infrastructure, since many of those notebook bays are not really hotplug-aware - etc... The kernel drivers are just implementing infrastructure for that AFAIU. And yes, Hannes is probably not going to implement all this :-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=217372 ------- Comment #12 from teheo@novell.com 2007-01-31 02:20 MST ------- First of all, using ahci is highly recommended for hotplugging if the port is SATA. If you use ahci, there is nothing special to do. The kernel notices device coming and going and notifies udev of the events and hald or whatever takes appropriate action eventually. This should be all automatic as-is. If ahci mode is not support, ata_piix can be used. In this case, there is no free device presence detection. Some notebooks use ACPI to notify device insertion and removal. udev rules should be written such that those ACPI events are captured and appropriate actions are taken. Please take a look at the following site for an example of how this can be done. http://www.thinkwiki.org/wiki/How_to_hotswap_UltraBay_devices Note that this becomes system-specific. I'm not sure how this should be handled. Maybe some new infrastructure is needed? If you intend to use drivers/ide/* drivers for hotplugging, I'm sorry but that just can't be done reliably. Maybe it can be hacked around by removing and reinserting driver module, which is ugly to say the least. Also, it's impossible on some systems where the primary harddisk is hooked up to the same controller. I don't think there is any sane way to add proper hotplug support to the old ide layer. All these are why we (libata ppl including Jeff, Alan, me and a few others) are trying to move everything over to libata.
