      drm/i915: Fix IPS related flicker · ac88cd73
      Rodrigo Vivi 提交于
      We cannot let IPS enabled with no plane on the pipe:
      
      BSpec: "IPS cannot be enabled until after at least one plane has
      been enabled for at least one vertical blank." and "IPS must be
      disabled while there is still at least one plane enabled on the
      same pipe as IPS." This restriction apply to HSW and BDW.
      
      However a shortcut path on update primary plane function
      to make primary plane invisible by setting DSPCTRL to 0
      was leting IPS enabled while there was no
      other plane enabled on the pipe causing flickerings that we were
      believing that it was caused by that other restriction where
      ips cannot be used when pixel rate is greater than 95% of cdclok.
      
      v2: Don't mess with Atomic path as pointed out by Ville.

      drm/i915: Another fbdev hack to avoid PSR on fbcon. · d9a946b5
      Rodrigo Vivi 提交于
      With unified modeset and flip paths introduced recently when switching
      to fbcon PSR was being disabled on fb_set_par path but re-enabled on
      fb_pan_display one, causing missed screen updates and un unusable
      console.

      drm/i915: Return the frontbuffer flip to enable intel_crtc_enable_planes. · 2d847d45
      Rodrigo Vivi 提交于
      Without this frontbuffer flip when enabling planes PSR got compromised
      and wasn't being enabled waiting forever on the flush that never
      arrived.
      
      Another solution would to create a enable_cursor function and split this
      frontbuffer flip among the different plane enable and disable functions.
      But if necessary this can be done in a follow up work. For now let's
      just fix the regression.
