      drm/i915: rip out crtc prepare/commit indirection · eae307a5
      Daniel Vetter 提交于
      Just impendance matching with the the crtc helper stuff.
      
      ... and somehow the design of this all ended up in this commit here,
      too ;-)
      
      The big plan is that this new set of crtc display_funcs take full
      responsibility of modeset operations for the entire display output
      pipeline (by calling down into object-specific callbacks and
      functions). The platform-specific callbacks simply know best what the
      proper order is.
      
      This has the drawback that we can't do minimal change-overs any more
      if a modeset just disables one encoder in a cloned configuration
      (because we will only expose a disable/enable action that takes
      down/sets up the entire crtc including all encoders). Imo that's the
      only sane way to do it though:
      - The use-case for this is pretty minimal, even when presenting (at
        least sane people) should use a dual-screen output so that you can
        see your notes on your panel. Clone mode is imo BS.
      - With all the clone mode constrains, shared resources, and special
        ordering requirements (which differ even on the same platform
        sometimes for different outputs) there's no way we'd get this right
        for all cases. Especially since this is a under-used feature.
      - And to top it off: On haswell even dp link re-training requires us
        to take down the entire display pipe - otherwise the chip dies.
      
      So the only sane way is to do a full modeset on every crtc where the
      output config changes in any way.
      
      To support global modeset (i.e. set the configuration for all crtcs at
      once) we'd then add one more function to allocate global and shared
      objects in the best ways (e.g. fdi links, pch plls, ...). The crtc
      functions would then simply use the pre-allocated stuff (and shouldn't
      be able to fail, ever). We could even do all the object pinning in
      there (and maybe try to defragment the global gtt if we fail)!

      drm/i915: add crtc->enable/disable vfuncs insted of dpms · 76e5a89c
      Daniel Vetter 提交于
      Because that's what we're essentially calling. This is the first step
      in untangling the crtc_helper induced dpms handling mess we have - at
      the crtc level we only have 2 states and the magic is just in
      selecting which one (and atm there isn't even much magic, but on
      recent platforms where not even the crt output has more than 2 states
      we could do better).
