RE: [PATCH V2 1/2] drm/amd/pm: restore user customized OD settings properly for NV1x
[AMD Official Use Only] Hi Alex & Lijo, For now, those code for updating OD table are in smu_cmn.c. And they can only be called from _ppt.c. So, unless we split some code from smu_cmn.c and move them to upper layer(suggested by Lijo before), otherwise this cannot be performed. So, definitely we need some follow up patches if we want this done in a more generic way.

RE: [PATCH V2 1/2] drm/amd/pm: restore user customized OD settings properly for NV1x
[Public] Hi Guchun, Currently, the smu->user_dpm_profile.flags seems only used to flag whether we are in a process restoring the user customized settings(power limit/fan settings/od settings etc). We could either drop it or expand its usage. Let me consider more and make a follow-up patch for this.

Re: [PATCH V2 1/2] drm/amd/pm: restore user customized OD settings properly for NV1x
The series looks good to me, though I prefer to use a common logic to restore od settings so that smuv12,smuv13 gets the restore feature by default once they add the user table logic. Don't have strong argument for it unless Alex, Kenneth or others have some comments.

[PATCH V2 1/2] drm/amd/pm: restore user customized OD settings properly for NV1x
The customized OD settings can be divided into two parts: those committed ones and non-committed ones. - For those changes which had been fed to SMU before S3/S4/Runpm suspend kicked, they are committed changes. They should be properly restored and fed to SMU on S3/S4/Runpm resume. - For those non-committed changes, they are restored only without feeding to SMU.
