If I remember well, that golden value would be again set to the golden value in mesa. Is there one golden value for all se/sh blocks? Or are there computed (then overwritting the golden value) values for each se/sh? Why mesa would overwrite its value (I have not checked in lastest mesa)? (drm-next-3.10 branch, head 28ff680d66b9c6b8dbe9436742e39a47a16ea396) ---- In drm-next-3.10 branch, commit c9e065819056dd00ccecbf17a73ade03fa03ca8e, in verde_golden_registers, many registers are set several times in a row, expected? (that does not look like sequential programing registers, maybe some register backbone block routing trickery?) ---- Regards, -- Sylvain
