   - Add support for the "Dhyana" x86 CPUs by Hygon: these are licensed
     based on the AMD Zen architecture, and are built and sold in China,
     for domestic datacenter use. The code is pretty close to AMD
     support, mostly with a few quirks and enumeration differences. (Pu
     Wen)

   - Enable CPUID support on Cyrix 6x86/6x86L processors"

     This allows to speed up the PMI handler by avoiding unnecessary MSR
     writes and make it more accurate. (Andi Kleen)

general:
- add battery charge data before and after test
- remove special s0i3 handling
- remove melding of dmesg &amp; ftrace data in old kernels, use one only
- updates to various kprobes in trace (ksys_sync, etc)
- enable pm_debug_messages during the test
- instrument more subsystems with dev functions (phy0)

error handling:
- return codes for tool show the status of the test run
- 0: success, 1: general error (no timeline), 2: fail (suspend aborted)
- monitor output of /sys/power/state, mark as failure if exception occurs
- add signal handler when using -result to catch tool exceptions

display control
- add -x commands for testing xset with mode settings and status
- allow display setting to on, off, suspend, standby
- add display mode change info to the log, along with a warning on fail

s2idle (freeze)
- remove fixed 10-phase dependency, allow any phase order &amp; any count
- multiple phase occurences show as phase_nameN e.g. suspend_noirq3
- if multiple freezes occur, print multiple time values in header

summary:
- add new columns to summary output: issues, worst suspend/resume devices
- worst device: includes summation of all phases of suspend or resume
- issues: includes WARNING/ERROR/BUG from dmesg log, and other issues
- s2idle: multiple freezes show as FREEZExN in the issues column

<title>cpupower: Fix coredump on VMWare</title>

<id>f69ffc5d3db8f1f03fd6d1df5930f9a1fbd787b6</id>
<content type='text'>
cpupower crashes on VMWare guests.  The guests have the AMD PStateDef MSR
(0xC0010064 + state number) set to zero.  As a result fid and did are zero
and the crash occurs because of a divide by zero (cof = fid/did).  This
can be prevented by checking the enable bit in the PStateDef MSR before
calculating cof.  By doing this the value of pstate[i] remains zero and
the value can be tested before displaying the active Pstates.

Check the enable bit in the PstateDef register for all supported families
and only print out enabled Pstates.

cpupower crashes on VMWare guests.  The guests have the AMD PStateDef MSR
(0xC0010064 + state number) set to zero.  As a result fid and did are zero
and the crash occurs because of a divide by zero (cof = fid/did).  This
can be prevented by checking the enable bit in the PStateDef MSR before
calculating cof.  By doing this the value of pstate[i] remains zero and
the value can be tested before displaying the active Pstates.

Check the enable bit in the PstateDef register for all supported families
and only print out enabled Pstates.

The msr_pstate data is only 63 bits long and should be 64 bits.

Add in the missing bit from res1 for AMD Family 0x17.
