[PATCH 0/8 v2]: turbostat: Fix AMD output by making turbostat aware of nodes

[PATCH 0/8 v2]: turbostat: Fix AMD output by making turbostat aware of nodes

[Prarit Bhargava]

AMD family processors do not show all cores in the output of turbostat.  This
occurs because AMD has multiple nodes per socket and enumerates cores
within each node from 0.  For example, socket 0 may have two nodes (0 and 1)
and those nodes both have cores enumerated from 0 through 7.  turbostat cannot
handle this configuration, and as a result only shows 1/2 the cores in its
output.

This patchset makes turbostate aware of nodes.  It has been tested on
various AMD and Intel systems and no issues have been found.

v2: Fix overwriting of thread_id in 3/8.  Add Node output to turbostat (patch
    8/8).  Various checkpatch.pl cleanups.

[PATCH 1/8 v2] turbostat: set max_num_cpus equal to the cpumask length

[Prarit Bhargava]

Future fixes will use sysfs files that contain cpumask output.  The code
needs to know the length of the cpumask in order to determine which cpus
are set in a cpumask.  Currently topo.max_cpu_num is the maximum cpu
number.  It can be increased the the maximum value of cpus represented in
cpumasks.

Set max_num_cpus to the length of a cpumask.

[PATCH 2/8 v2] turbostat: Fix node and siblings lookup data

[Prarit Bhargava]

The turbostat code only looks at thread_siblings_list to determine if
processing units/threads are on the same the core.  This works well on
Intel systems which have a shared L1 instruction and data cache.  This
does not work on AMD systems which have shared L1 instruction cache but
separate L1 data caches.  Other utilities also check sibling's core ID
to determine if the processing unit shares the same core.

Additionally, the cpu_topology *cpus list used in topology_probe() can
be used elsewhere in the code to simplify things.

Export *cpus to the entire turbostat code, and add Processing Unit/Thread
IDs information to each cpu_topology struct.  Confirm that the thread
is on the same core as indicated by thread_siblings_list.

[PATCH 3/8 v2] turbostat: Calculate additional node information for a package

[Prarit Bhargava]

The code currently assumes each package has exactly one node.  This is not
the case for AMD systems and Intel systems with COD.  AMD systems also
may re-enumerate each node's core IDs starting at 0 (for example, an AMD
processor may have two nodes, each with core IDs from 0 to 7).  In order
to properly enumerate the cores we need to track both the physical and
logical node IDs.

Add physical_node_id to track the node ID assigned by the kernel, and
logical_node_id used by turbostat to track the nodes per package ie) a
0-based count within the package.

The code can be simplified if the cpu_topology *cpus tracks the thread

initialization code.

Add thread ID to cpu_topology information and cleanup the counter

[PATCH 5/8 v2] turbostat: rename num_cores_per_pkg to num_cores_per_node

[Prarit Bhargava]

turbostat incorrectly assumes that there is one node per package.  As a
result num_cores_per_pkg is not correctly named and is actually
num_cores_per_node.

Rename num_cores_per_pkg to num_cores_per_node.

[PATCH 7/8 v2] turbostat: add node information into turbostat calculations

[Prarit Bhargava]

The previous patches have added node information to turbostat, but the
counters code does not take it into account.

Add node information from cpu_topology calculations to turbostat
counters.
