/dev/bsp is the IOSU device node for the Board Support Package. It provides functions to interface with the hardware and checks for access permissions.
It is subdivided in entities (e.g. SMC, USB, SDIO, SATA, ...) and each entity has a number of attributes (e.g baseAdddress, size, pin0); entities can set multiple instance to have different attributes.
List of entities and attributes (wip)
| Entity | Attributes |
|---|---|
| SMC | ODDPower, EjectRequest, ONIndicator, CCIndicator, OFFIndicator, BTRSTPulse, WIFIRSTPulse, DWIFIRSTPulse, USBRearControl, USBFrontControl, WIFIResetPin, TimerCounter, ProgramRevision, SystemEventFlag, NotificationLED, PowerFailureState, LAPSSetting, SystemError |
| WIFI | WIFI_ENABLED |
| GFX | subsystem, endianness, spll, upll, vi1pll, vi2pll, DCCMPT |
List of ioctls
| Command | Function | Description |
|---|---|---|
| 0x01 | bspGetEntityVersion(entityName = &buffer_in[0..7], buffer_io[0] = version) | Writes the version number for the specified entity in buffer_io. |
| 0x02 | bspMethodGetHardwareVersion(buffer_io[0] = hwVersion) | Writes the hardware version in buffer_io. |
| 0x03 | bspGetConsoleMask(buffer_io[0] = mask) | Writes the a mask that depends on consoleType and boardType in buffer_io. |
| 0x04 | bspMethodQuery(entityName = buffer_in[0..7], instance = buffer_in[8], attributeName = buffer_in[9..16], size = buffer_in[17], buffer_io = pData) | Calls the query method for the specified entity->attribute. |
| 0x05 | bspMethodRead(entityName = buffer_in[0..7], instance = buffer_in[8], attributeName = buffer_in[9..16], size = buffer_in[17], buffer_io = pData) | Calls the read method for the specified entity->attribute. |
| 0x06 | bspMethodWrite(entityName = buffer_in[0..7], instance = buffer_in[8], attributeName = buffer_in[9..16], size = buffer_in[17], pData = buffer_io[72..72+size]) | Calls the write method for the specified entity->attribute. |
| 0x07 | bspMethodInit(entityName = buffer_in[0..7], instance = buffer_in[8], attributeName = buffer_in[9..16], optionSize = buffer_in[17], pOptions = buffer_io[72..72+optionSize]) | Calls the init method for the specified entity->attribute. |
| 0x08 | bspMethodShutdown(entityName = buffer_in[0..7], instance = buffer_in[8], attributeName = buffer_in[9..16]) | Calls the shutdown method for the specified entity->attribute. |
| 0x09 | bspGetConsoleType(buffer_io[0] = consoleType) | Writes a consoleType (2 = retail/test, 3 and 4 = probably debug) in buffer_io. |
