2022-05-27drm/i915/bios: Split VBT data into per-panel vs. global partsVille Syrjälä1-1/+1
Move the panel specific VBT parsing to happen during the output probing stage. Needs to be done because the VBT parsing will need to look at the EDID to determine the correct panel_type on some machines. We split the parsed VBT data (i915->vbt) along the same boundary. For the moment we just hoist all the panel specific stuff into connector->panel.vbt since that seems like the most convenient place for eg. the backlight code. Note that we simply drop the drrs type check from intel_drrs_frontbuffer_update() since that operates on the whole device rather than a specific connector/encoder. But the check was just a micro optimization so removing it doesn't actually mattter for correctness. TODO: Lot's of cleanup to be done in the future. Eg. most of the DSI stuff could probably be eliminated entirely and just parsed on demand during DSI init. v2: Note the intel_drrs_frontbuffer_update() change Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220510104242.6099-13-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

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 <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220311172428.14685-7-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

All fixed mode panels should behave the same way when it comes to mode filtering. Reuse the intel_panel_mode_valid() for all of them. This changes the behaviour to match what we do for eDP, ie. reject anything that doesn't exactly match the fixed mode dimensions. Users can still manually provide different sized modes which will be handled by the panel fitter just as before. The difference is that we can no longer report funny modes in the connector's mode list.

2019-09-19drm/i915: Don't advertise modes that exceed the max plane sizeVille Syrjälä1-1/+2
Modern platforms allow the transcoders hdisplay/vdisplay to exceed the planes' max resolution. This has the nasty implication that modes on the connectors' mode list may not be usable when the user asks for a fullscreen plane. Seeing as that is the most common use case it seems prudent to filter out modes that don't allow for fullscreen planes to be enabled. Let's do that in the connetor .mode_valid() hook so that normally such modes are kept hidden but the user is still able to forcibly specify such a mode if they know they don't need fullscreen planes. This is in line with ealier policies regarding certain clock limits. The idea is to prevent the casual user from encountering a mode that would fail under typical conditions, but allow the expert user to force things if they so wish. Maybe in the future we should consider automagically using two planes when one can't cover the entire screen? Wouldn't be a great match for the current uapi with explicit planes though, but I guess no worse than using two pipes (which we apparently have to in the future anyway). Either that or we'd have to teach userspace to do it for us. v2: Fix icl+ max plane heigth (Manasi) Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Leho Kraav <leho@kraav.com> Cc: Sean Paul <sean@poorly.run> Cc: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190918150707.32420-1-ville.syrjala@linux.intel.com
