2022-04-28drm/amd/pm: fix the deadlock issue observed on SIEvan Quan1-10/+0
The adev->pm.mutx is already held at the beginning of amdgpu_dpm_compute_clocks/amdgpu_dpm_enable_uvd/amdgpu_dpm_enable_vce. But on their calling path, amdgpu_display_bandwidth_update will be called and thus its sub functions amdgpu_dpm_get_sclk/mclk. They will then try to acquire the same adev->pm.mutex and deadlock will occur. By placing amdgpu_display_bandwidth_update outside of adev->pm.mutex protection(considering logically they do not need such protection) and restructuring the call flow accordingly, we can eliminate the deadlock issue. This comes with no real logics change.

In file vega10_hwmgr.c, the names of struct vega10_power_state * and struct pp_power_state * are confusingly used, which may lead to some confusion. Status quo is that variables of type struct vega10_power_state * are named "vega10_ps", "ps", "vega10_power_state". A more appropriate usage is that struct are named "ps" is used for variabled of type struct pp_power_state *. So rename struct vega10_power_state * which are named "ps" and "vega10_power_state" to "vega10_ps", I also renamed "psa" to "vega10_psa" and "psb" to "vega10_psb" to make it more clearly.

2021-09-23drm/amd/pm: Update intermediate power state for SILijo Lazar1-0/+2
Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").
