2026-06-03drm/amd/display: Disable FRL and add module param to enable itFangzhi Zuo1-0/+4
FRL links don't yet support VRR. If we enable it by default users will see a functional regression when connected to an FRL capable display as the driver will now default to FRL and not allow VRR. VRR support will come soon, so instead of making an elaborate TMDS fallback mechanism simply default FRL to disabled, but provide a dcfeaturemask of 0x400 to enable it if anyone wants to already try it out.

2026-05-27drm/amd/pm: Rename enable_bapm() to notify_ac_dc()Timur Kristóf1-1/+1
No functional changes, just change the name of this function pointer to be more generic. BAPM refers to a specific feature on KV, but other kinds of ASICs may also need the SMU to be notified on AC/DC changes. Also remove the argument and use adev->pm.ac_power instead.

2026-05-11drm/amdgpu: add psp interfaces for peak tops limiter driverPerry Yuan2-0/+51
Introduce a Peak Tops Limiter (PTL) driver that dynamically caps engine frequency to ensure delivered TOPS never exceeds a defined TOPS_limit. This initial implementation provides core data structures and kernel-space interfaces (set/get, enable/disable) to manage PTL state. PTL performs a firmware handshake to initialize its state and update predefined format types. It supports updating these format types at runtime while user-space tools automatically switch PTL state, and also allows explicitly switching PTL state via newly added commands.

Instead, define it in one common header file (acpi_bus.h) so that it is accessible to all of its users. No intentional functional impact. Signed-off-by: Rafael J.
