Nothing special about ivb+ here, if DRRS works on ivb+ port A it should work just as well on ilk/snb. So let's enable that. Reviewed-by:

No reason to keep the DRRS enable/disable hidden insider the encoder hooks. Let's just move them all the way up into platform independent code so that all platforms get to use them. These are nops when the state computation doesn't think DRRS is possible. Reviewed-by:

Ger rid of one more ugly crtc->config usage by storing the DRRS state under intel_crtc. intel_drrs_enable() copies what it needs from the crtc state, after which DRRS can be blissfully ignorant of anything going on around it. This also lets multiple pipes do DRRS simultanously and entirely independently. v2: Split out some stuff (Jani) Signed-off-by:

Ville Syrjälä authored
The DRRS code has no use for the intel_dp, replace it with just a crtc pointer. This is just an intermediate step towards making DRRS truly per-crtc. Signed-off-by:

Add a helper to determine which type of DRRS the panel supports. Signed-off-by:

There are a couple of cases where we essentially just want to get/check the preferred fixed mode of the panel. Add a small helper for that to abstract away the direct pointer lookup. Signed-off-by:

Several connectors want to return the fixed_mode from .get_modes(), add a helper to do that (and hide the details inside intel_panel.c). Signed-off-by:
-
Ville Syrjälä authored
Abstract away the details on where we store the fixed/downclock modes, and also how we select them. Will be useful for static DRRS (aka. allowing the user to select the refresh rate for the panel). We pass in the user requested mode to intel_panel_fixed_mode() so that in the future it may try to match the refresh rate. And intel_panel_downclock_mode() gets passed the adjusted_mode we actually chose to use so that it may find a suitable lower resresh rate variant. v2: Hook it up for all encoders s/fixed_mode/adjusted_mode/ in intel_panel_downclock_mode() (Jani) Elaborate on the choice or arguments for the functions (Jani) Signed-off-by: -
Ville Syrjälä authored
When we found a downclock mode dev_priv->drrs.type is just a straight copy of dev_priv->vbt.drrs_type. And in case we couldn't find a downclock mode can_enable_drrs() won't let us enable DRRS anyway so the minor distinction between the two is irrelevant. So let's just nuke dev_priv->drrs.type and consult the VBT version directly. Signed-off-by:

No need for all this connector type special casing. If the connector has a fixed mode just print it, otherwise don't. Signed-off-by:
-
Ville Syrjälä authored
We want to eventually get rid of the connector->panel.fixed_mode pointer so avoid using it during LVDS setup. Since this all happens during the encoder init we already have the fixed_mode around, just pass that in. Signed-off-by:

Ville Syrjälä authored
We want to stop using connector->panel.fixed_mode directtly. In order to look it up in the future we'll need to have the requested mode around, so pass that in fully (instead of just passing bits of it). Signed-off-by:

Rename the PIPECONF refresh rate select bits to be less cryptic. Also nothing eDP specific about these as they also select between FP0 vs. FP1 for the DPLL and thus can be used to change the refresh rate on other output types as well. Signed-off-by:

Remove the comment specifying the exact formulat for calculating the DPLL frequency from the *_find_best_dpll() functions. Each platform variant has its own way to calculate these and we have the code already to do that. These comments are entirely redundant and often even wrong so just get rid of them. Signed-off-by:

Ville Syrjälä authored
Unify vlv/chv with earlier platforms so that the sturct dpll::dot represents the /5 clock frequency (ie. DP symbol rate or HDMI TMDS rate) rather than the *5 fast clock (/2 of the bitrate). Makes life a little less confusing to get the same number back in .dot which we fed into the DPLL algorithm. v2: Actually just include the 5x in the final P divider Do the same change to the hand rolled gvt code v3: Missed a few *5 in *_find_best_dpll() Reviewed-by: -

When using bigjoiner it's useful to know the offset of each individual pipe in the whole set of joined pipes. Let's include that information in our PIPESRC rectangle. With this we can make the plane clipping code blissfully unaware of bigjoiner usage, as all we have to do is remove the pipe's offset from the final plane destination coordinates. v2: Use intel_bigjoiner_num_pipes() Signed-off-by:

Replace the hardcoded 2 pipe assumptions when we're massaging pipe_mode and the pipe_src rect to be suitable for bigjoiner. Instead we can just count the number of pipes in the bitmask. v2: Introduce intel_bigjoiner_num_pipes() Signed-off-by:

Ville Syrjälä authored
Since we now have the bigjoiner_pipes bitmask the boolean is redundant. Get rid of it. Also, populating bigjoiner_pipes already during encoder->compute_config() allows us to use it much earlier during the state calculation as well. The initial aim is to use it in intel_crtc_compute_config(). v2: Move the hweight(bigjoiner_pipes) stuff to a later patch Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> #v1 Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> #v1 Signed-off-by:
