[Hardy Feature Request] Add EDD support

[Jose De la Rosa]

Hardy Feature Request to add EDD (BIOS Enhanced Disk Driver) support in Server and Desktop OS.

http://linux.dell.com/projects.shtml#edd

[Jose De la Rosa (jose-de-la-rosa)]

The EDD feature will appear in the -10 kernel (Alpha 6). The default behavior for server is CONFIG_EDD_OFF=n (EDD is enabled), Every other flavour is CONFIG_EDD_OFF=y (EDD is disabled) for backward compatibility.

This has been implemented in kernel 2.6.24-10+. See http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=b88bbb0c71a195b96d3d8a0cf3087888b6d89610 for more information.

Well this is implemented at a kernel level, but the udev rules don't work.

[Scott James Remnant (Canonical) (canonical-scott)]

What udev rules don't work?

[Mario Limonciello (superm1)]

Scott,

As it stands, there is support in the kernel for EDD when you pass "edd=on". When EDD is enabled, you can manually run /lib/udev/edd_id /dev/sda and get the correct response. The symlinks that are supposed to be populated in /dev/disk/by-id for EDD are not generated however.

Udev persistent-storage-edd rules need to come after the persistent-storage rules, else certain env vars are missing. Fixes is in the process of being uploaded.
