Subject: [PATCH] sparc64: Don't use devspec to determine the OBP path
|
|
|
|
Don't use devspec to determine the OBP path on SPARC hardware. Within all
|
|
versions of Linux on SPARC, the devspec returns one of three values:
|
|
"none", "vnet-port", or "vdisk". Unlike on PPC, none of these values
|
|
are useful in determining the OBP path.
|
|
|
|
Before this patch grub-ofpathname always returned the wrong value
|
|
for a virtual disk. For example:
|
|
|
|
% grub-ofpathname /dev/vdiskc2
|
|
vdisk/disk@2:b
|
|
|
|
After this patch it now returns the correct value:
|
|
|
|
% grub-ofpathname /dev/vdiskc2
|
|
/virtual-devices@100/channel-devices@200/disk@2:b
|
|
|
