This patch series adds support of NVMeoFC on grub. It consists of six
patches.
Patch 1/6
(0001-ieee1275-powerpc-implements-fibre-channel-discovery-.patch):
grub-ofpathname doesn't work with fibre channel because there is no
function currently implemented for it.
This patch enables it by prividing a function that looks for the port
name, building the entire path for OF devices.
Patch
2/6(0002-ieee1275-powerpc-enables-device-mapper-discovery.patch):
This patch enables the device mapper discovery on ofpath.c. Currently,
when we are dealing with a device like /dev/dm-* the ofpath returns
null
since there is no function implemented to handle this case.
This patch implements a function that will look into /sys/block/dm-*
devices and search recursively inside slaves directory to find the
root
disk.
Patch
3/6(0003-ieee1275-implement-FCP-methods-for-WWPN-and-LUNs.patch):
This patch enables the fcp-targets and fcp-luns methods which are
responsible to get WWPNs and LUNs for fibre channel devices.
Those methods are specially necessary if the boot directory and grub
installation are in different FCP disks, allowing the dev_iterate()
to find the WWPNs and LUNs when called by searchfs.uuid tool.
Patch 4/6(0004-change-partition-parser.patch):
Usually grub will parse the PFW arguments by searching for the first
occurence of the character ':'.
However, we can have this char more than once on NQN.
This patch changes the logic to find the last occurence of this char
so we can get the proper values
for NVMeoFC
Patch 5/6(0005-ieee1275-add-support-for-NVMeoFC.patch):
This patch implements the functions to scan and discovery of NVMeoFC.
Patch
6/6(0006-ieee1275-ofpath-enable-NVMeoF-logical-device-transla.patch):
This patch add code to enable the translation of logical devices to
the of NVMeoFC paths.
We are nearing to the code freeze and I am stopping getting new
features
which were not approved/reviewed by the GRUB maintainers earlier. So,
please do not except any reviews from me in the following weeks. Though
I will certainly will take a look at the series after the GRUB
release...

Hi Daniel,
How are you!
Did you get a chance to look NVMeoFC patch series?
Thank you!
