[Intel-gfx] [PATCH v9 0/4] Add hwmon support for dgfx selftests

[Riana Tauro]

Rename librapl library to libpower. Add hwmon support in libpower for
dgfx.
Use libpower in selftests.

Rev2 : Update commit message
Rev3 : Remove redundant code
Rev4 : Add hwmon per-gt support
Rev5 : No functional changes.
       Change author for last patch
Rev6 : re-order libpower library patch
       add check for single gt in hwmon function
Rev7 : Same as Rev 5 with a single gt check
       in hwmon function
Rev8 : Skip power comparison in live_rc6_manual for
       discrete graphics
Rev9 : Update commit message

Riana Tauro (3):
  drm/i915/selftests: Rename librapl library to libpower

[Intel-gfx] [PATCH v9 2/4] drm/i915/hwmon: Add helper function to obtain energy values

[Riana Tauro]

Add an interface to obtain hwmon energy values. The function returns
per-gt energy if gt level energy is available else returns the package
level energy if there is a single gt.
This is used by selftests to verify power consumption

v2 : use i915_hwmon prefix (Anshuman)
v3 : re-use is_visible function of energy to remove
     redundant code (Anshuman)
v4 : fix kernel-doc (Anshuman)
     add per-gt hwmon support (Ashutosh)
v5 : add check to return package level energy only when there
     is a single gt and gt level energy is not available. (Ashutosh)

[Intel-gfx] [PATCH v9 3/4] drm/i915/selftests: Add hwmon support in libpower for dgfx

[Riana Tauro]

From: Tilak Tangudu <tilak.tangudu@intel.com>

hwmon provides an interface to read energy values for discrete graphics.
add hwmon support to the existing libpower library so that it can verify
power consumption values in different selftests.

Changed prototype of libpower_get_energy_uJ

v2: add per-gt hwmon support (Ashutosh)

[Intel-gfx] [PATCH v9 4/4] drm/i915/selftests: skip comparison of power for discrete graphics

[Riana Tauro]

Hwmon reads the energy/power consumed by discrete soc,
i.e. energy/power includes the power drawn from non-gfx discrete
components

This test uses the power consumed by GT to validate RC6
power consumption.
Skip comparison of power for discrete graphics

TODO : measure power of GT in discrete graphics and modify the
condition

v2: update commit message (Anshuman)

So this condition is not being met for dGfx?

On dGfx, is this true even when we have per-gt level energy available? Or
only when we have device level energy but not per-gt level energy (when
total number of gt's is 1 and we only expose device level energy but not gt
level energy)?

If we are adding this TODO, how are we planning to do this?

Seems we are going this for device level energy. In that case should we
change the condition below to say device level energy for dGfx (rather than
just dGfx)? So it will be clear. Something "analogous" to how we do this in
i915_hwmon_get_energy():

+       else if (!HAS_EXTRA_GT_LIST(gt->i915) && hwm_energy_is_visible(ddat, hwmon_energy_input))
+               hwm_energy(ddat, energy);

So here we are going to come up with a different condition for this device
level energy? Is it possible to do this now itself rather than add the
TODO?

Thanks.
