[v7,0/7] DC3CO Support for TGL

Message

Gupta, Anshuman Sept. 7, 2019, 5:14 p.m. UTC

This is a new design proposal for DC3CO feature after discussing
it with Ville and Imre.

Unlike v6 this v7 version has a cleaner solution to froce the
modeset at bootup by using a crtc_state state bool
has_dc3co_exitline in order to configure and enable dc3co exitline.

Suggestion and feedback are most welcome for this new design
series.

Anshuman Gupta (7):
  drm/i915/tgl: Add DC3CO required register and bits
  drm/i915/tgl: Add DC3CO mask to allowed_dc_mask and gen9_dc_mask
  drm/i915/tgl: Enable DC3CO state in "DC Off" power well
  drm/i915/tgl: Do modeset to enable and configure DC3CO exitline.
  drm/i915/tgl: DC3CO PSR2 helper
  drm/i915/tgl: switch between dc3co and dc5 based on display idleness
  drm/i915/tgl: Add DC3CO counter in i915_dmc_info
