2025-04-12drm/{i915,xe}: Move intel_pch under displayRodrigo Vivi
The only usage of the "PCH" infra is to detect which South Display Engine we should be using. Move it under display so we can convert all its callers towards intel_display struct later. No functional or code change.

2025-03-31drm/i915/dram: Consolidate logging of DRAM typeLucas De Marchi
Instead of logging the dram type in the per version/platform function, do it in the generic one. This fixes a few discrepancies depending on the platform: - There was no DRAM type logging for graphics version 12 and above - For graphics version 11, it would log the DRAM type in skl_get_dram_info(), but could possibly override it later without any log in icl_pcode_read_mem_global_info() For bxt_get_dram_info(), there's no need to log the type for each dimm, as the drm_WARN_ON() already covers the case they are not all the same. This maintains the behavior of skl_get_dram_info() that would log the DRAM type even on failures.

Some new dram types were added without adding the corresponding string conversion, probably because it's not being used by recent platforms.

On MTL, both the North Display (NDE) and South Display (SDE) functionality reside on the same die (the SoC die in this case), unlike many past platforms where the SDE was on a separate PCH die. The code is (badly) structured today in a way that assumes the SDE is always on the PCH for modern platforms, so on platforms where we don't actually need to identify the PCH to figure out how the SDE behaves (i.e., all DG1/2 GPUs as well as MTL and LNL),we've been assigning a "fake PCH" as a quickhack that allows us to avoid restructuring a bunch of the code.we've been assigning a "fake PCH" as a quick hack that allows us to avoid restructuring a bunch of the code.

2023-10-05drm/i915/display: Created exclusive version of vga decode setupUma Shankar
Current vga arbiter implementation in i915 needs a re-design. The current approach would cause real problems if anyone actually needs to talk another GPU using legacy VGA resources. The main issue is that X becomes a slideshow if it thinks there are multiple GPUs that have VGA decoding enabled as it insists on adjusting the VGA routing pretty much for every little operation involving any of the GPUs. The cleanup will be planned for i915. Meanwhile to focus on Xe upstreaming and have a cleaner separation, the said functionality is being moved to a different file exclusive for i915.

Xe2_LPD doesn't have south display engine on a PCH, it's actually on the SoC die (while north display engine is on compute die). As such it makes no sense to go through the PCI devices looking for an ISA bridge. The approach used by BXT/GLK can't be used here since leaving it with PCH_NONE would mean taking the wrong code paths. For the places we currently use a PCH check, it's enough for now to just check the north display version. Use that to define a fake PCH to be used across the driver.

2023-01-25drm/i915/gmch: split out soc/intel_gmchJani Nikula
The GMCH related code is a bit too low level and out of place for the high level i915_driver.c file. Split out to a separate file under soc/. Rename the functions accordingly.

2022-12-13drm/i915: add new "soc" sub-directory and move PCH and DRAM code thereJani Nikula
Add a new sub-directory for things that aren't specifically about the GPU and don't really belong in the i915 driver top level, but also don't belong under any of the existing sub-directories either. Name it "soc", and move the PCH and DRAM code there.
