a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A Both SM8550 and SM8650 misuse mdp1-mem interconnect path for the LLCC->EBI path, while it should only be used for the MDP->EBI paths. This kind of misuse can result in bandwidth underflows, possibly degradating picture quality as the required memory bandwidth is divided between all mdpN-mem paths (and LLCC-EBI should not be a part of such division). Drop mdp1-mem paths and use MDP-EBI path directly.
