Subject: [PATCH 1/3] drmgr: don't open sysfs file for each command
The new __do_kernel_dlpar() API will be used in later commit to remove by
DRC Index LMB per LMB. This will avoiding opennig and closing the fd each
time.
The fd closing will now be done at the process exit time.
In addition add an optinal parameter to silently ignore some error.
Also, change the log level of the "success" message to debug to match
the previous one saying "Trying.."

Subject: [PATCH] drmgr: fix remove by index operation
The commit e9f06531356f ("drmgr: introduce NUMA based LMB removal")
introduce a special processing when NUMA is on and the remove by count
operation is done.
Unfortunately, that code is also triggered when doing a remove by index
operation (-s argument) becauses usr_drc_count is set to 1. As a
consequence the index constraint is not respected and any LMB can be
removed.
Add a check agains usr_drc_index which is set when a remove by index
operation is done to ensure the numa removal code is not triggered in that
case.
Fixes: e9f06531356f ("drmgr: introduce NUMA based LMB removal")

Subject: [PATCH] ofpathname: Use NVMe controller physical nsid
Linux creates logical block devices of the the form nvmeXnYpZ such that X = the
controller, Y = namepsace, and Z = partition. For example:
/dev/nvme0n1p1
The Linux namespace numbering scheme for namespaces always starts at 1 and
increases monotonically regardless of the actual numbering scheme of the
namespaces as seen by the physical NVMe controller. Accordingly, the Open
firmware path binding utilizes the namespace id as seen by the controller and
not the necessarily the one given in the logical block device name.
As such we need to use the "nsid" attribute in the sysfs entry for the logical
device to properly map back and forth from OP pathnames.

Subject: [PATCH 2/3] drmgr: read the CPU NUMA topology
This will be used in the next commit to compute LMB removal based on the
NUMA topology.
The NUMA topology is read using the libnuma, so a dependency against it is
added in the configure file.

Subject: [PATCH 3/3] drmgr: introduce NUMA based LMB removal
When the NUMA topology can be read, all the LMBs found in the Device Tree
are linked the corresponding node. LMB not associated to node are
considered as not used.
LMB associated to CPU less node are accounted separately because they will
be targeted first to be remove. The LMB are removed from the CPU less nodes
to reach an average number LMBs per CPU less node.
Node with CPU have a ration indexed on their number of CPUs. The higher a
node have CPU the lower number LMB will be removed. This way node with a
high number of CPU will get a higher amount of memory.
When a LMB can't be removed (because its memory can't be offlined by the
kernel), the LMB count for node is decremented and the LMB is removed from
the node's LMB list. This way, it is no more accounted as 'active' and the
removal operation will continue without taking it in account anymore.
The removal is done through the remove by DRC index API, allowing to remove
a LMB at a time. One futur optimization would be to extend that API to
remove a linear range of LMB each time.
If the NUMA topology can't be read, we fallback using the legacy remove
way.

Fix checking HCNID array size at boot time
In commit 0b59d4a372aa266caa75f3b6a253b8f5aeaf3802 it checks the HCNID array
empty to avoid cleanup non-HNV related network profiles after reboot.
hcnmgr scan run log shows checking the number of HCNID array elements has
not done properly.

hcnmgr: Avoid cleanup of bond interface at boot time when no HNV exists
At boot time, hcn scans the device tree and discovers if there was a new
HNV being added while lpar was inactive. It also cleans up the old hnv
interfaces. This patch avoids cleaning up bonding interface when no HNV
network devices exists.

hcnmgr: Avoid using xargs to process NM show connections
When removing HNV bonding connections xargs can fail to process the output of
nmcli show propererly.
Instead of piping into xargs fix this by using a loop to check for all related

At the time of calling ofpathname to look up for devicename, wait

hcnmgr: Avoid using ifcfg file for checking bonding interface status
When configuring migratable sr_iov into hybrid network, it checks if
there is an existing HNV using the presense of ifcfg file location. This
is not preferred as the location can be different on distros.
This patch fixes this by using NetworkManager nmcli.

Clean up dead network config interface after inactive migration
With inactive parition migration, we found there are
dead network interface asscoiated with the SR_IOV from
source LPAR that still exist.
We need to cleanup the old network interface
related to this devname from source LPAR. Normally
in the active parition migration case, this was done
when HMC issue commands to OS remove the
VF from hybrid network. Because of the inactive
migration, the OS was not notified before migration
that the VF was removed, thus leaves the dead network
interface belongs on the original MVF on source lpar
not cleaned up. This cause the confusion of the network
manager to bring up the bondings with new MVFs at destination
LPAR.
After inactive parition migration the same devname
could possiblily used at the destination LPAR.
It can be assigned to a different hybrid
network (different hcnid). At the OS boot time,
the same devname but with different hcnid will
be configured. However the old network work interface
associated with the same devname from the source LPAR
has not been cleaned up yet.
This patch fix this by during the boot time scan and
if found an VFs has more than two bonding interfaces,
or has old VF ifcfg, removed the expired one.

HNV fixes for qrydev and remove lsdevinfo
This patch fixes a few issues found during testing:
1) Fix qrydev checking for active interface error
2) Skip collecting lsdevinfo right before migration
When the LPARs has large number of devices, this can
take quite a long time and flood the log message.
3) Wait for OS ready to lookup device name for configure
HNV device. We need give OS longer time to prepare pci
device after DLPAR to show up for ofpathname(). We have
run into several issues HNV issues the hcncfgdrc command
to configure the vdevices before ofpathname able
to find the device name yet.
4) Currently the hybrid network virtualization is only
supported on PowerVM LPAR. We should allow exit the hcnmgr
gracefully on other power platform instead of return error.

commit 97269d301797e23b75d0c7a5cb63ce280783f615
Author: Laurent Dufour <ldufour@linux.ibm.com>
Date: Thu Mar 4 14:51:38 2021 +0100
lpartstat: add -x option for the security flavor
This allows user to get the security flavor settings fer the LPAR.
The output is :
$ lparstat -x
Speculative Execution Mode : 1
Where the output number means
0 = Speculative execution fully enabled
1 = Speculative execution controls to mitigate user-to-kernel side-channel
attacks
2 = Speculative execution controls to mitigate user-to-kernel and
user-to-user side-channel attacks
In the case the running kernel is not exposing the security flavor in
/proc/powerpc/lparcfg, the output is:
$ lparstat -x
Speculative Execution Mode : -
