Subject: [PATCH] drmgr: Return from get_node_by_name() if matched DRC index
Upstream: merged, expected in v1.3.13
Git-commit: 1dc1ecf7dce7825d352b045c98aa51711b58aaca
get_node_by_name() should return dr_node if the DRC name or DRC
index is matched. But the current code returns only if the DRC
name is matched. This patch fixes this issue and returns dr_node
if the index is matched.

Subject: [PATCH 1/4] drmgr/pci: Enable in-kernel functionality to update
device tree
drmgr updates the device tree by writing to /proc/ppc64/ofdt. Also
invokes configure_connector RTAS call to retrieve new device nodes
for IO ADD. But this functionality need /dev/mem access which is
restricted under system lockdown.
The kernel updates provided a sysfs file (/sys/kernel/dlpar) that
will allow drmgr command invoke the following interfaces to update
the device tree.
dt add index <DRC index> ---> To add new device nodes to the device
tree which is used for IO ADD.
dt remove index <DRC index> ---> To remove device nodes for IO
REMOVE
This patch checks the kernel interface for the availability of
device tree update feature and adds do_dt_kernel_dlpar() to invoke
the above kernel interfaces.

Subject: [PATCH] lparstat: Fix Idle and busy PURR/SPURR
Upstream: merged, expected in v1.3.13
Git-commit: 2af8c0b9a285e8a6104560d0f482819e56060443
lparstat -E gives %busy and %idle for actual(PURR based) and normalized
(SPURR based).Idle and busy PURR/SPURR values are not adding upto 100%
in case of dedicated-donate and shared partitions, with the present
formula. Because of this, users might get a false impression of resource
utilisation. This is expected because a core can be in either
idle or busy state out of total of 100(core's shared resource can
either be consumed or be left idle). When lpar is in dedicated-donate
or shared,the purr values are not being counted when the CPU is ceded.
The idle_purr is calculated by taking snapshots of purr values at
every idle entry and idle exit. So, when a CPU is ceded, the calculation
for idle_purr will be wrong as purr is not being counted.

This commit, rather than considering delta_idle_purr for calculation of
idle ticks, takes (delta_tb - delta_purr + delta_idle_purr) as total
ticks for which the CPUs were idle. Here, since delta_idle_purr will
also contain some idle ticks, thats why it is added to the formula.
Since, the output was correct for dedicated capped mode, changes has
been made only for shared and dedicated-donate mode.
Further, no changes has been made for calculation of %busy.
Similar changes has been done for SPURR.

Subject: [PATCH] lparstat: app: Use pic value at boot for accurate boot time
reporting
Upstream: merged, expected in v1.3.13
Git-commit: 81c51b59aacaa66d90d571ee19a2deeda1d45271
When there are no options specified for lparstat, it is expected to
give reports since LPAR(Logical Partition) boot. APP(Available Physical
Processors) is an indicator for available cores in an Shared Processor
LPAR(SPLPAR). APP is derived using pool_idle_time which is obtained
using H_PIC call.
The interval based reports show correct APP value while since boot
report shows very high APP values. This happens because in that case APP
is obtained by dividing pool idle time by LPAR uptime. Since pool idle
time is reported by the PowerVM hypervisor since its boot, it need not
align with LPAR boot.
To fix that use the boot pool idle time added newly in the lparcfg as
below.
APP = (pool idle time - boot pool idle time) / (uptime * timebase)
*This depends on "powerpc/pseries: Add pool idle time at LPAR boot" be
merged into kernel*
Results: (Observe APP values)

reboot
stress-ng --cpu=$(nproc) -t 600
sleep 600
So in this case app is expected to close to 37-6=31.

Subject: [PATCH] lparstat: Use CLOCK_BOOTTIME for get_time interface and
Deprecate get_sys_upttime
Upstream: merged, expected in v1.3.13
Git-commit: 9572f8c2022fed9783f0f606cbe778ffe0d93fef
"time" is used in lparstat.c to find the time elapsed either since boot
or between two intervals. But it is using gettimeofday which returns the
time elapsed since Epoch. This works for intervals calculations but it
doesn't work for since boot reports.
Instead use the CLOCK_BOOTTIME interface to get the elapsed time. This
fixes physc, utilization based on purr being wrong since boot.
Remove "uptime" interface since there are no users of it. One can get
the system uptime by calling "time" itself.

Interval based lparstat values are same. With this patch the physc and

Note: this patch doesn't fix the idle purr being incorrect. That is

When using ofpathname to find the logical device associated to a Fibre

can be returned if a device with no devspec attribute is in the list of

If a device with no devspec is found simply skip it an continue the

ofpathname: Convert logical path to OF device path for virtio-scsi devices
Add support to convert logical device path to Open firmware device path
for virtio-scsi devices.
lsslot/drmgr: little endian support for memory
This patch adds some support for memory slot listing
and memory hotplugging on little endian systems.
drmgr: Correct -s option handling
The usage statement for drmgr claims that we can add/remove memory and cpus
by drc name or drc index. The current code though assumes that any
use of the -s flag to specify this defaults to drc name.
This patch updates the option checking for memory and cpu operations to
allow users to specify a drc index with the -s option. This will be
handled the same way the -s option for pci devices is handled, assume it
is a drc name unless it starts with '0x', indicating the string is
really a hex value, and switching it to a drc index.
drmgr: Correct null pointer usage
We can't de-reference NULL pointers, it's not a nice thing to do.
I found these during some debugging, correcting to avoid future bugs.

lparstat: using get_smt_mode when showing SMT info
get_smt_state is used in the system_data structure to display both the
shared_processor_mode and the smt_state members. After reviewing code and
documentation, it seems that the information in smt_state is meant to be
acquired from ppc64_cpu instead of lparcfg. With this change, the SMT listin
will be determined by the output of ppc64_cpu --smt.
ppc64_cpu: Allow builds without librtas
Currently, --without-librtas disables ppc64_cpu.
However, we only need librtas for the run-mode determination; other
functions will work fine without it.
This change allows ppc64_cpu to be built without librtas, by
conditionally enabling run-mode, and restoring ppc64_cpu to be built
when --without-librtas is given.
We need to re-work src/Makefile.am a little here - we use the +=
operator to include rtas-specific functionality, which means the
with-librtas cases need to be listed before the without ones.
We also need to #include stdint.h, as ppc64_cpu.c uses inttypes from
here.
drmgr: Correct the -s option handling correction
In response to my earlier patch that attempted to correct the -s option hand
for drmgr I introduced a bug in which the usr_drc_name could be NULL causing
a segfault when attempting to use it.
This patch adds a check to make sure it is not NULL.

Subject: [PATCH] ppc64_cpu: Clean up sysfs smt/control error handling
When the kernel does not support the sysfs intercface do not report an
arror, fall back to the old method silently.

Subject: [PATCH] ppc64_cpu: Support partial SMT level through SYS FS
smt/control files
The next kernel release will support partial SMT level [1] though the SYS
FS file "devices/system/cpu/smt/control". This allows the SMT level to be
recorded in the kernel. With the current SMT level stored in the kernel,
when a new CPU is added, only the necessary threads are brought online.
The legacy way to active threads through the SYS FS files
'devices/system/cpu/cpu<n>/online', is still used in the case the new SYS
FS API is not available. This allows compatibility with the previous kernel
versions.
