Some SKUs of Xe2_HPD platforms (such as BMG) have GDDR memory type with ECC enabled. We need to identify this scenario and add a new case in xelpdp_get_dram_info() to handle it. In addition, the derating value needs to be adjusted accordingly to compensate for the limited bandwidth.

FYI, this does not cherry-pick cleanly to drm-intel-next-fixes, and needs a backport.
There are dependencies on at least
4051c59e2a6a ("drm/i915/xe3lpd: Update bandwidth parameters") 9377c00cfdb5 ("drm/i915/display: Convert intel_bw.c internally to intel_display") d706998b6da6 ("drm/i915/display: Convert intel_bw.c externally to intel_display")
but I don't think we want to backport those.
BR, Jani.
