turbostat displays a GFXMHz column, which comes from reading
/sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz
But GFXMHz was not changing, even when a manual
cat /sys/class/graphics/fb0/device/drm/card0/gt_cur_freq_mhz
showed a new value.
It turns out that a rewind() on the open file is not sufficient,
fflush() (or a close/open) is needed to read fresh values.

When the "u32" keyword is used with --add, it means that
the output should be truncated to 32-bits. This was not
happening and all 64-bits were printed.
Also, when no column name was used for an added MSR,
The default column name was in deximal, eg. MSR16.
Users report that they tend to use hex MSR numbers,
so print them in hex. To always fit into the columns,
use the syntax M0x10. Note that the user can always
supply any column header that they want.
eg --add msr0x10,MY_TSC

When turbostat is run in one-shot command mode,
the parent takes the 'before' counter snapshot,
fork/exec/wait for the child to exit,
takes the 'after' counter snapshot,
and prints the results.
however, if the child fails to exec the command,
it immediately returns, without indicating that
anythign was wrong.
Add an error message showing that exec failed:
sudo turbostat sleeeep 4
...
turbostat: exec sleeeep: No such file or directory
...
Note that the parent will still print out the statistics,
because it can't tell the difference between the failed
exec and a command that is purposefully returning
the same status. Unfortunately, this may obscure the
error message. However, if the --out parameter is used,
the error message is evident on stderr.

Originally, the only way to hide the sysfs C-state statistics columns
was with "--hide sysfs". This was because we process "--hide" before
we probe for those columns.
hack --hide to remember deferred hide requests, and apply
them when sysfs is probed.
"--hide sysfs" is still available as short-hand to refer to
the entire group of counters.
The down-side of this change is that we no longer error check for
bogus --hide column names. But the user will quickly figure that

When turbostat shows % of time in a CPU idle power state,
it has always been showing information from underlying
hardware residency counters.
While this reflects what the hardware is doing, and is thus
useful for understanding the hardware,
it doesn't directly tell us what Linux requested --
which is useful for tuning Linux itself.
Here we add columns to turbostat to show the
Linux cpuidle sub-system statistics:
/sys/devices/system/cpu/cpu*/cpuidle/state*/*
The first group of columns are the "usage", which is the
number of times software requested that C-state in the
measurement interval. eg C1 below.
The second group of columns are the "time", which is the percentage
of the measurement interval time that software has requested
the specified C-state. eg C1% below.
These software counters can be compared to the underlying
hardware residency counters (eg CPU%c1 CPU%c3 CPU%c6 CPU%c7)
to compare what sofware requested to what the hardware delivered.
These sysfs attributes are discovered when turbostat starts,
rather than being "built in". So the --show and --hide
parameters do not know about these dynamic column names.
However "--show sysfs" and "--hide sysfs" act on the
entire group of columns:
turbostat --show sysfs

Newer processors do not hard-code the the number of cpus in each bin

38 * 100.0 = 3700.0 MHz max turbo 3 active cores
39 * 100.0 = 3800.0 MHz max turbo 2 active cores
39 * 100.0 = 3900.0 MHz max turbo 1 active cores
could now look something like this:
...
37 * 100.0 = 3600.0 MHz max turbo 16 active cores
38 * 100.0 = 3700.0 MHz max turbo 8 active cores

The CC1 column in tubostat can be computed by subtracting
the core c-state residency countes from the total Cx residency.
CC1 = (Idle_time_as_measured by MPERF) - (all core C-states with
residency counters)
However, as the underlying counter reads are not atomic,
error can be noticed in this calculations, especially
when the numbers are small.
Denverton has a hardware CC1 residency counter
to improve the accuracy of the cc1 statistic -- use it.
At the same time, Denverton has no concept of CC3, PC3, CC7, PC7,
so skip collecting and printing those columns.
Finally, a note of clarification.
Turbostat prints the standard PC2 residency counter,
but on Denverton hardware, that actually means PC1E.
Turbostat prints the standard PC6 residency counter,
but on Denverton hardware, that actually means PC2.
At this point, we document that differnce in this commit message,
rather than adding a quirk to the software.

The CPU ticks at a rate in the "bus clock" domain.
eg. 100 MHz * bus_ratio.
On newer processors, the TSC has been moved out of this BCLK
domain and into a separate crystal-clock domain.
While the TSC ticks "close to" the base frequency, those that look
closely at the numbers will notice small errors in calculations that
mix units of TSC clocks and bus clocks.
"tsc_tweak" was introduced to address the most visible
mixing -- the %Busy and the the Busy_MHz calculations.
(A simplification as since removed TSC from the BusyMHz calculation)
Here we apply the tsc_tweak to everyplace where BCLK
and TSC units are mixed. The results is that
on a system which is 100% idle, the sum of the C-states
are now much more likely to be closer to 100%.

Some users want turbostat to tell them everything, by default.
Some users want turbostat to be quiet, by default.
I find that I'm in the 1st camp, and so I've never liked
needing to type the --debug parameter to decode the system
configuration.
So here we change the default and print the system configuration,
by default. (The --debug option is now un-documented, though
it does still exist for debugging turbostat internals)
When you do not want to see the system configuration

Some time ago, turbostat overflowed 80 columns.
So on the assumption that a "casual" user would always
want topology and frequency columns, we hid the rest
of the columns and the system configuration decoding
behind the --debug option.
Not everybody liked that change -- including me.
I use --debug 99% of the time...
Well, now we have "-o file" to put turbostat output into a file,
so unless you are watching real-time in a small window,
column count is less frequently a factor.
And more recently, we got the "--hide columnA,columnB" option
to specify columns to skip.
So now we "un-hide" the rest of the columns from behind --debug,
and show them all, by default.

If BPF_F_ALLOW_OVERRIDE flag is used in BPF_PROG_ATTACH command
to the given cgroup the descendent cgroup will be able to override
effective bpf program that was inherited from this cgroup.
By default it's not passed, therefore override is disallowed.
Examples:
1.
prog X attached to /A with default
prog Y fails to attach to /A/B and /A/B/C
Everything under /A runs prog X
2.
prog X attached to /A with allow_override.
prog Y fails to attach to /A/B with default (non-override)
prog M attached to /A/B with allow_override.
Everything under /A/B runs prog M only.
3.
prog X attached to /A with allow_override.
prog Y fails to attach to /A with default.
The user has to detach first to switch the mode.
In the future this behavior may be extended with a chain of

The -o/--order option is to select column number to sort a diff result.
It does the job by adding a hpp field at the beginning of the sort list.
But it should not be added to the output field list as it has no
callbacks required by a output field.
During the setup_sorting(), the perf_hpp__setup_output_field() appends
the given sort keys to the output field if it's not there already.
Originally it was checked by fmt->list being non-empty. But commit
3f931f2c42 ("perf hists: Make hpp setup function generic") changed it
to check the ->equal callback.
Anyways, we don't need to add the pseudo hpp field to the output field
list since it won't be used for output. So just skip fields if they
have no ->color or ->entry callbacks.
