The package power can also be read from an MSR. It's not clear exactly
what is included, and whether it's aggregated over all nodes or
reported separately.
It does look like this is reported separately per CCX (I get a single
value on the Ryzen R7 1700), but it might be reported separately per-
die (node?) on larger processors. If that's the case, it would have to
be recorded per node and aggregated for the socket.
Note that although Zen has these MSRs reporting power, it looks like
the actual RAPL configuration (power limits, configured TDP) is done
through PCI configuration space. I have not yet found any public
documentation for this.

Based on the Open-Source Register Reference for AMD Family 17h
Processors Models 00h-2Fh:
https://support.amd.com/TechDocs/56255_OSRR.pdf
These processors report RAPL support in bit 14 of CPUID 0x80000007 EDX,
and the following MSRs are present:
0xc0010299 (RAPL_PWR_UNIT), like Intel's RAPL_POWER_UNIT
0xc001029a (CORE_ENERGY_STAT), kind of like Intel's PP0_ENERGY_STATUS
0xc001029b (PKG_ENERGY_STAT), like Intel's PKG_ENERGY_STATUS
A notable difference from the Intel implementation is that AMD reports
the "Cores" energy usage separately for each core, rather than a
per-package total. The code has been adjusted to handle either case in a
generic way.
I haven't yet enabled collection of package power, due to being unable
to test it on multi-node systems (TR, EPYC).

turbostat fails on some multi-package topologies because the logical node

This patch fixes a regression introduced in
commit 8cb48b32a5 ("tools/power turbostat: track thread ID in cpu_topology")
Turbostat uses incorrect cores number ('topo.num_cores') - its value is count
of logical CPUs, instead of count of physical cores. So it is twice as large as
it should be on a typical Intel system. For example, on a 6 core Xeon system
'topo.num_cores' is 12, and on a 52 core Xeon system 'topo.num_cores' is 104.
And interestingly, on a 68-core Knights Landing Intel system 'topo.num_cores'
is 272, because this system has 4 logical CPUs per core.
As a result, some of the turbostat calculations are incorrect. For example,
on idle 52-core Xeon system when all cores are ~99% in Core C6 (CPU%c6), the
summary (very first) line shows ~48% Core C6, while it should be ~99%.
This patch fixes the problem by fixing 'topo.num_cores' calculation.
Was:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id != -1 (bug!)
Now:
1. Init 'thread_id' for all CPUs to -1
2. Run 'get_thread_siblings()' which sets it to 0 or 1
3. Increment 'topo.num_cores' when thread_id is not 0
I did not have a chance to test this on an AMD machine, and only tested on a
couple of Intel Xeons (6 and 52 cores).

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 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.
