Bug ID: 221505
Summary: REGRESSION][amd_pstate] "EPP cannot be set under
performance policy" (EBUSY) when switching to
performance profile via PPD on 7.1
Product: Power Management
Version: 2.5
Hardware: AMD
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: cpufreq
Assignee: linux-pm@vger.kernel.org
Reporter: sergeyluashkov@gmail.com
Regression: No

dmesg
Hardware: ASUS TUF Gaming A14 (2026) FA401EA
CPU: AMD Ryzen AI Max+ 932 (Strix Halo platform)
Kernel: 7.1.0-mainline (including patches for Bugzilla #221310)
Power Daemon: power-profiles-daemon 0.30
Description:
On kernel 7.1, power-profiles-daemon fails to activate the "performance"
profile. The D-Bus error returned is Code 26 (Device or resource busy).
After enabling dynamic debug for the amd_pstate module (echo 'module amd_pstate
+p' > /sys/kernel/debug/dynamic_debug/control), I captured the following reason
for the failure in dmesg:
[ 299.585428] amd_pstate: EPP cannot be set under performance policy
Steps to Reproduce:
Use a system with amd_pstate in active mode on kernel 7.1.
Attempt to switch profile: powerprofilesctl set performance.
Failed to communicate with power-profiles-daemon: g-io-error-quark:
GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dio_2derror_2dquark.Code26:
Failed to activate CPU driver 'amd_pstate': Error writing
'/sys/devices/system/cpu/cpufreq/policy11/energy_performance_preference':
Device or resource busy (26)
The command fails, and dmesg logs: amd_pstate: EPP cannot be set under
performance policy.
Expected Result:
The driver should allow setting the EPP value even if the policy is set to
performance, or handle the transition gracefully without returning EBUSY to
user-space daemons.
Additional Context:
This issue was observed on the new Strix Halo (Ryzen AI Max+) platform. The
conflict between PPD's profile orchestration and the driver's internal state
checks makes the "Performance" profile unusable via standard desktop tools
(KDE/GNOME power settings).
I can build and test custom patches on this hardware

> Did you set CONFIG_X86_AMD_PSTATE_DYNAMIC_EPP
After enabling CONFIG_X86_AMD_PSTATE_DYNAMIC_EPP=y, power-profiles-daemon (PPD)
loses the ability to switch to the power-saver profile. Attempting to set it
via powerprofilesctl set power-saver results in the system defaulting back to
balanced.
Technical details:
Governor limitation:
cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_governors returns
only [performance, powersave].
PPD Failure:
Since only two governors are visible, PPD fails to map the "power-saver"
profile correctly, even though the underlying hardware supports it.
Manual Override:
I discovered that the only way to successfully force the "power-saver" state is
by writing directly to the platform profile:
echo "quiet" | sudo tee
/sys/devices/platform/asus-nb-wmi/platform-profile/platform-profile-25/profile
(Note: The path may vary, but the "quiet" hint works where PPD fails).
Steps to Reproduce:
Enable CONFIG_X86_AMD_PSTATE_DYNAMIC_EPP=y.
Try to set power-saver: powerprofilesctl set power-saver.
Check status: powerprofilesctl get returns balanced.
Expected Result:
PPD should recognize that in active/dynamic_epp mode, "power-saver" should map
to the powersave governor with an EPP hint of power (or quiet at the platform
level)
Actual Result:
PPD is stuck between two profiles (balanced/performance)

Yes - this is expected behavior with the series right now. I am proposing to
drop the kconfig and make the dynamic epp mode opt in at runtiem or kernel
command line.

I’ve tested the kernel from your amd-pstate-fixes branch (commit f9f16835d4dc),
but unfortunately, the issues persist, and I’ve discovered a new conflict with
the ASUS platform driver.
Current observations:
With amd_dynamic_epp=disable (or no parameter):
The behavior remains identical to the initial report. powerprofilesctl still
fails with the error described in the original report (Description).
With amd_dynamic_epp=enable:
It breaks the integration with asus-nb-wmi.
Specifically, the /sys/devices/platform/asus-nb-wmi/throttle_thermal_policy
(which controls ASUS thermal profiles) stops switching to value 2
(Silent/Power-save mode).
When I set "Power-saver" via PPD, it only toggles between 0 and 1.
The CPU TDP is not limited to its expected ~55W threshold unless I manually
write 2 to the throttle_thermal_policy file.

Can I see the kernel log with dynamic debug for amd-pstate turned on? And also
the output from the amd-pstate triage tool in amd-debug-tools.
