an attempt to have userspace tools not poke at naked MSRs. This round
 deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
 by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
 interface which we already have.

 about which userspace tools write MSRs:

6c4832253a tools/power/x86/intel-speed-select: Account for missing sysfs for die_id
Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.

Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.

This helps in running this tool on older kernels with just Intel SST
drivers back ported.

3d7772ea56 tools/power turbostat: harden against cpu hotplug
turbostat tends to get confused when CPUs are added and removed
while it is running.

There are races, such as checking the current cpu, and then
reading a sysfs file that depends on that cpu number.

Close the two issues that seem to come up the most.
First, there is an infinite reset loop detector --
change that to allow more resets before giving up.
Secondly, one of those file reads didn't really need
to exit the program on failure...

b4b9156953 tools/power turbostat: Add a new GFXAMHz column that exposes gt_act_freq_mhz.
The column already present called GFXMHz reads from gt_cur_freq_mhz,
which represents the GT frequency that was requested, but power
management might not be able to do that. So the new column will display
what the actual frequency GT is running at.

0936cdfbb5 tools/power x86_energy_perf_policy: Input/output error in a VM
I've encountered an issue with x86_energy_perf_policy. If I run it on a
machine that I'm told is a qemu-kvm virtual machine running inside a
privileged container, I get the following error:

x86_energy_perf_policy: /dev/cpu/0/msr offset 0x1ad read failed: Input/output error

I get the same error in a Digital Ocean droplet, so that might be a
similar environment.

I created the following patch which is intended to give a more
user-friendly message. It's based on a patch for turbostat from Prarit
Bhargava that was posted some time ago. The patch is "[v2] turbostat:
Running on virtual machine is not supported" [1].

Given my limited knowledge of the topic, I can't say with confidence
that this is the right solution, though (that's why this is not an
official patch submission). Also, I'm not sure what the convention with
exit codes is in this tool. Also, instead of the error message, perhaps
the tool should just not print anything in this case, which is how it
behaves in a "regular" VM?

fecb3bc839 tools/power turbostat: Fix output formatting for ACPI CST enumeration
turbostat formatting is broken with ACPI CST for enumeration.  The
problem is that the CX_ACPI% is eight characters long which does not
work with tab formatting.  One simple solution is to remove the underbar
from the state name such that C1_ACPI will be displayed as C1ACPI.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

87e15da957 tools/power turbostat: Introduce functions to accumulate RAPL consumption
Since the RAPL Joule Counter is 32 bit, turbostat would
only print a *star* instead of printing the actual energy
consumed to indicate the overflow due to long duration.
This does not meet the requirement from servers as the
sampling time of turbostat is usually very long on servers.

So maintain a set of MSR buffer, and update them
periodically before the 32bit MSR register is wrapped round,
so as to avoid the overflow.

The idea is similar to the implementation of ktime_get():

Periodical MSR timer:
total_rapl_sum += (current_rapl_msr - last_rapl_msr);

Using get_msr_sum() to get the accumulated RAPL:
return (current_rapl_msr - last_rapl_msr) + total_rapl_sum;

The accumulated RAPL mechanism will be turned on in next patch.
