2025-06-09drm/i915: split out display register macros to a separate fileJani Nikula
This is a scripted split of the display related register macros from i915_reg.h to display/intel_display_regs.h. As a starting point, move all the macros that are only used in display code (or GVT). If there are users in core i915 code or soc/, or no users anywhere, keep the macros in i915_reg.h. This is done in groups of macros separated by blank lines, moving the comments along with the groups. Some manually picked macro groups are kept/moved regardless of the heuristics above. This is obviously a very crude approach. It's not perfect. But there are 4.2k lines in i915_reg.h, and its refactoring has ground to a halt. This is the big hammer that splits the file to two, and enables further cleanup.

2025-05-12drm/i915: Add support for forcing the link bpp on a connectorImre Deak
Add support for forcing the link bpp on a connector via a connector debugfs entry. During reducing link bpps due to a link BW limit, keep bpps close to their forced value.

2025-04-15drm/i915/display: Add link rate and lane count to i915_display_infoKhaled Almahallawy
Adding link rate and lane count information to i915_display_info makes it easier and faster to access this data compared to checking kernel logs. This is particularly beneficial for individuals who are not familiar with i915 in the following scenarios: * Debugging DP tunnel bandwidth usage in the Thunderbolt driver. * During USB4 certification, it is necessary to know the link rate used by the monitor to prove that the DP tunnel can handle required rates. * In PHY CTS, when the connector probes are not mounted correctly, some display lanes may not appear in the DP Oscilloscope, leading to CTS failures. This change provides validation teams with an easy way to identify and troubleshoot issues. v2: separate seq_printf line (Jani) v3: separate output line (Jani) Cc: Imre Deak <imre.deak@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://lore.kernel.org/r/20250409230214.963999-1-khaled.almahallawy@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2024-09-23drm/i915/dp: move DP test debugfs files next to the functionalityJani Nikula
Move the DP test debugfs files to intel_dp_test.[ch]. Side note: The debugfs looks like it begs to be converted to connector debugfs, but that's for another day.

2024-09-19drm/i915/display: add intel_bo_describe() and use itJani Nikula
Add an interface based on struct drm_gem_object, and use it. This lets us delete the compat i915_debugfs.h header.

2024-09-19drm/i915/debugfs: add dedicated intel_display_caps debugfs for displayJani Nikula
Add dedicated intel_display_caps for display, with device info and params. Intentionally prefix the file intel_ instead of i915_. Going forward, we should do the same for all debugfs files, making them independent of i915 and xe. Remove display param dumping from i915 specific i915_capabilities debugfs. Note that we don't add node_to_intel_display() functionality in to_intel_display(). It's too specific for that.
