AFAICS that should happen if your surface pool description looks
something like this:
caps = CSPCAPS_PHYSICAL | CSPCAPS_VIRTUAL;
access[CSAID_CPU] = CSAF_READ | CSAF_WRITE | CSAF_SHARED;
access[CSAID_GPU] = CSAF_READ | CSAF_WRITE | CSAF_SHARED;
types = CSTF_LAYER | CSTF_WINDOW | CSTF_CURSOR | CSTF_FONT |
CSTF_SHARED | CSTF_INTERNAL | CSTF_EXTERNAL;
priority = CSPP_ULTIMATE;
access[CSAID_LAYER0] = CSAF_READ;
...
