9e752ee26c drm/amdgpu/smu14.0.2: fix IP version check

3912a78cf7 drm/amd/pm: Set SMU v13.0.7 default workload type
Set the default workload type to bootup type on smu v13.0.7.
This is because of the constraint on smu v13.0.7.
Gfx activity has an even higher set point on 3D fullscreen
mode than the one on bootup mode. This causes the 3D fullscreen
mode's performance is worse than the bootup mode's performance
for the lightweighted/medium workload. For the high workload,
the performance is the same between 3D fullscreen mode and bootup
mode.

v2: set the default workload in ASIC specific file

1443dd3c67 drm/amd/pm: fix and simplify workload handling
smu->workload_mask is IP specific and should not be messed with in
the common code. The mask bits vary across SMU versions.

Move all handling of smu->workload_mask in to the backends and
simplify the code.  Store the user's preference in smu->power_profile_mode
which will be reflected in sysfs.  For internal driver profile
switches for KFD or VCN, just update the workload mask so that the
user's preference is retained.  Remove all of the extra now unused
workload related elements in the smu structure.

v2: use refcounts for workload profiles
v3: rework based on feedback from Lijo
v4: fix the refcount on failure, drop backend mask
v5: rework custom handling
v6: handle failure cleanup with custom profile
v7: Update documentation

c3d06a3b6a Revert "drm/amd/pm: correct the workload setting"
This reverts commit 74e1006430.

This causes a regression in the workload selection.
A more extensive fix is being worked on.
For now, revert.

This came back after a merge in 6.13-rc1, so revert again.

commit 7c210ca5a2 ("drm/amdgpu: handle default profile on on devices without fullscreen 3D")
While everything is set correctly, this caused the profile to be
reported incorrectly because both the powersave and fullscreen3d bits
were set in the mask and when the driver prints the profile, it looks
for the first bit set.

Empirically we can confirm that the former allocates 152 bytes for the
table, while the latter memsets the 168 large block.

Root cause appears that when GPU metrics tables for v2_4 parts were added
it was not considered to enlarge the table to fit.

The fix in this patch is rather "brute force" and perhaps later should be
done in a smarter way, by extracting and consolidating the part version to
size logic to a common helper, instead of brute forcing the largest
possible allocation. Nevertheless, for now this works and fixes the out of
bounds write.

v2:
 * Drop impossible v3_0 case. (Mario)

8a5ae927b6 drm/amdgpu: partially revert powerplay __counted_by changes
Partially revert
commit 0ca9f757a0 ("drm/amd/pm: powerplay: Add `__counted_by` attribute for flexible arrays")

The count attribute for these arrays does not get set until
after the arrays are allocated and populated leading to false
UBSAN warnings.

6e796cb4a9 drm/amd/pm: use pm_runtime_get_if_active for debugfs getters
Don't wake up the GPU for reading pm values. Instead, take a runtime
powermanagement ref when trying to read it if and only if the GPU is
already awake.

This avoids spurious wake ups (eg: from applets).

We use pm_runtime_get_if_in_active because we care about "is the GPU awake?"
not about "is the GPU awake and something else prevents suspend?".

ef532206a9 drm/amd/pm: don't update runpm last_usage on debugfs getter
Reading pm values from the GPU shouldn't prevent it to be suspended
by resetting the last active timestamp (eg: if an background app
monitors GPU sensors every second, it would prevent the autosuspend
sequence to trigger).
