The OCC common area is mapped at a unique address on the system and each OCC is assigned a segment to expose its sensor data : ------------------------------------------------------------------------- | Start (Offset from | End | Size |Description | | BAR2 base address) | | | | ------------------------------------------------------------------------- | 0x00580000 | 0x005A57FF |150kB |OCC 0 Sensor Data Block| | 0x005A5800 | 0x005CAFFF |150kB |OCC 1 Sensor Data Block| | : | : | : | : | | 0x00686800 | 0x006ABFFF |150kB |OCC 7 Sensor Data Block| | 0x006AC000 | 0x006FFFFF |336kB |Reserved | ------------------------------------------------------------------------- Maximum size is 1.5MB. We could define a "OCC common area" memory region at the machine level and sub regions for each OCC. But it adds some extra complexity to the models. Fix the current layout with a simpler model.
