With that, please check your downstream dmesg and look for a line like this: "<6>[ 0.000000] cma: CMA: reserved 36 MiB at 0x0000000003800000 for cont_splash_mem" This is there for me on both 8994-kitakami and 8992-xiaomi-libra. Qualcomm devices tend to map "dynamically-allocated" regions to the same addresses every time. Konrad
