Hi, Which GPU generations/families do use the "new" powerplay CAC table, defined when the atombios platform capabilities have the ATOM_PP_PLATFORM_CAP_NEW_CAC_VOLTAGE flag? ---- On drm-next-3.13 branch, commit 70471860ff9f335c60c004d42ebd48945bfa5403, I noticed the following: For the "new" power CAC table, there is a relationship with the table defining the link between vddc and the engine clock. My tahiti based board does use the "old" cac table, but I noticed the use of a virtual value (0xff??) for vddc in the vddc dependency on engine clock table which is not translated to a real voltage value. This is found in si_dpm.c, si_get_std_voltage_value function. Would that would explain why there are 2 lookup loops in si_get_std_voltage_value function? (one looking for the exact value, the other one seems to be a trick to deal with untranslated virtual voltage). regards, -- Sylvain _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
