drm/amd: Allow printing VanGogh OD SCLK levels without setting dpm to manual

2025-08-20T16:36:12+00:00

[ Upstream commit 2d1ec1e955414e8e8358178011c35afca1a1c0b1 ]

Several other ASICs allow printing OD SCLK levels without setting DPM
control to manual.  When OD is disabled it will show the range the
hardware supports. When OD is enabled it will show what values have
been programmed. Adjust VanGogh to work the same.

drm/amd/pm: fix null pointer access

2025-08-20T16:36:03+00:00

[ Upstream commit d524d40e3a6152a3ea1125af729f8cd8ca65efde ]

Writing a string without delimiters (' ', '\n', '\0') to the under
gpu_od/fan_ctrl sysfs or pp_power_profile_mode for the CUSTOM profile
will result in a null pointer dereference.

drm/amd/pm/powerplay/hwmgr/smu_helper: fix order of mask and value

2025-08-15T10:16:28+00:00

[ Upstream commit a54e4639c4ef37a0241bac7d2a77f2e6ffb57099 ]

There is a small typo in phm_wait_on_indirect_register().

Swap mask and value arguments provided to phm_wait_on_register() so that
they satisfy the function signature and actual usage scheme.

Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.

In practice this doesn't fix any issues because the only place this
function is used uses the same value for the value and mask.

drm/amdgpu: disable workload profile switching when OD is enabled

2025-07-06T09:04:22+00:00

commit 5cccf10f652122a17b40df9d672ccf2ed69cd82f upstream.

Users have reported that they have to reduce the level of undervolting
to acheive stability when dynamic workload profiles are enabled on
GC 10.3.x. Disable dynamic workload profiles if the user has enabled
OD.

drm/amd/pm: Reset SMU v13.0.x custom settings

[ Upstream commit 923406e74ec66364b829b7f8b6b67d46200567a6 ]

On SMU v13.0.2 and SMU v13.0.6 variants user may choose custom min/max
clocks in manual perf mode. Those custom min/max values need to be
reset once user switches to auto or restores default settings.
Otherwise, they may get used inadvertently during the next operation.

drm/amd/pp: Fix potential NULL pointer dereference in atomctrl_initialize_mc_reg_table

2025-06-19T13:39:29+00:00

[ Upstream commit 820116a39f96bdc7d426c33a804b52f53700a919 ]

The function atomctrl_initialize_mc_reg_table() and
atomctrl_initialize_mc_reg_table_v2_2() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table()
fails to retrieve vram_info, it returns NULL which is later
dereferenced.
