The forcewake_get call in the guc_send_mmio function was added to avoid getting and releasing forcewake on each register access. While this makes sense, all GuC registers are in the blitter range so no need to wake all the wells.

2017-03-23drm/i915/guc: A little bit more of doorbell sanitizationOscar Mateo1-9/+12
Some recent refactoring patches have left the doorbell creation outside the GuC client allocation, which does not make a lot of sense (a client without a doorbell is something useless). Move it back there, and refactor the init_doorbell_hw consequently. Thanks to this, we can do some other improvements, like hoisting the check for GuC submission enabled out of the enable function. v2: Rebased.

We can WARN right away and merge cases 1 and 2.

Instead of calling intel_guc_init() and intel_huc_init() one by one this patch introduces intel_uc_init_fw() function that calls them both. Called functions are renamed accordingly. Trying to have subject_verb_object ordering and more descriptive names, the intel_huc_init() and intel_guc_init() functions are renamed. For guc_init(): * `intel_guc` is the subject, so those functions now take intel_guc structure, instead of the dev_priv * init is the verb * fw is the object which better describes the function's role huc_init() change follows the same reasoning. v2: settle on intel_uc_fetch_fw name (M.
