[Bug 1549298] Re: Add missing MSRs for powertop

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Or mark it as "Fix Released" if the problem has been solved with a 
newer version of QEMU already. Thank you and sorry for the inconvenience.

** Changed in: qemu
       Status: New => Incomplete

Title:
  Add missing MSRs for powertop

Status in QEMU:
  Incomplete

Bug description:
  I reported this same bug on the powertop bugtracker [1] because I
  think both projects need to change something here.

  When running powertop it crashes and prints:

    unknown op '{'
                  read_msr cpu0 0xe8 : Input/output error

  It seems that powertop is trying to access model specific registers and 
because qemu doesn't emulate them it crashes.
  Clearly powertop shouldn't crash in such case but I think it would also be 
better if qemu could add support for these registers.
