Function Documentation

unsigned int SUMT_addrChipToLocal (  unsigned int  baseAddr, unsigned short  chipAddr )

Translate a Summit address into a CPU address. The Summit chip keeps track of addresses as 16-bit words relative to the base address of device shared memory. This function translates a chip address (as found in a device register) to a CPU local address. Parameters: baseAddr  The CPU local base address of device shared memory. chipAddr  The Summit address value. Returns: The chipAddr translated to a software address pointer.

unsigned short SUMT_addrLocalToChip (  unsigned int  baseAddr, unsigned int  localAddr )

Translate a CPU address into a Summit address. The Summit chip keeps track of addresses as 16-bit words relative to the base address of device shared memory. This function translates a CPU local address into a value suitable for chip usage (as in a device register). Parameters: baseAddr  The CPU local base address of device shared memory. localAddr  A software address pointer. Returns: A 16-bit Summit address value.

void SUMT_memCopyIn (  void *  dest, unsigned int  src, unsigned int  numWords )

Copy data from Summit shared memory. The Summit device shared memory is usually only able to be accessed as 16-bit words from the CPU side. This is to support the 16-bit word addressing scheme of the Summit device. This function copies a region of device shared memory into a user buffer by only accessing 16-bit words at a time. Any PCI endian issues are also handled. Parameters: dest  The destination address of the copy. src  The source address of the copy. numWords  The number of 16-bit words to copy.

void SUMT_memCopyOut (  unsigned int  dest, void *  src, unsigned int  numWords )

Copy data into Summit shared memory. The Summit device shared memory is usually only able to be accessed as 16-bit words from the CPU side. This is to support the 16-bit word addressing scheme of the Summit device. This function copies a region of device shared memory out of a user buffer by only accessing 16-bit words at a time. Any PCI endian issues are also handled. Parameters: dest  The destination address of the copy. src  The source address of the copy. numWords  The number of 16-bit words to copy.

void SUMT_memSet (  unsigned int  dest, unsigned short  value, unsigned int  numWords )

Set Summit shared memory to known value. The Summit device shared memory is usually only able to be accessed as 16-bit words from the CPU side. This is to support the 16-bit word addressing scheme of the Summit device. This function sets a region of device shared memory by only accessing 16-bit words at a time. Parameters: dest  The address of the device memory to clear. value  The value to write to shared memory. numWords  The number of 16-bit words to clear.

unsigned int SUMT_regWrite (  unsigned int  addr, unsigned int  offset, unsigned short  data, unsigned short  mask )

Write to a Summit controller register. Writes a value to one of the Summit controller internal registers. This function performs a read back of the register to verify that the write was successful. Up to SUMT_REG_RETRY retries are allowed before declairing failure. A warning is signalled for every retry. This is related to a problem seen with the EM model SIB board running with a MCP750 CPU. Parameters: addr  The base address of the Summit registers. offset  The offset to the register to write. data  The register data value. mask  A bitmask of the register's writable bits. Used for validation. Returns: A CTDB MSG code.

unsigned int SUMT_reset (  unsigned int  regs  )

Soft reset Summit controller hardware. Performs a software reset of the Summit controller chip. Parameters: regs  The base address of the Summit registers. Returns: A CTDB MSG code.

void SUMT_rtLegalize (  unsigned short *  regPair, unsigned short  subAddr )

Create a Summit legalization mask. Creates a bit mask for the Summit illegalization register values. The appropriate bit in one of the regPair words is cleared to allow the indicated subaddress to appear at the remote terminal. Parameters: regPair  A pointer to a pair of 16-bit illegalization values. subAddr  The subaddress value to legalize.

unsigned int SUMT_test (  unsigned int  regs  )

Perform Summit controller hardware built in test. Performs a built in self test (BIT) of the Summit controller chip. A warning is issued if one of the tests reports failure. An error code is returned if both the Channel A and Channel B tests fail, the BIT procedure times out, or if the device does not return to ready status after running the BIT. Parameters: regs  The base address of the Summit registers. Returns: A CTDB MSG code.

unsigned short SUMT_wordRead (  unsigned int  addr, unsigned int  offset )

Synchronized read of Summit register or shared memory location. Reads one 16-bit value from the Summit internal registers or from the device shared memory. Parameters: addr  The device address to write. offset  The offset of the address to write from addr in 16-bit words. Returns: The 16-bit hardware value.

void SUMT_wordWrite (  unsigned int  addr, unsigned int  offset, unsigned short  data )

Synchronized write to Summit register or shared memory location. Writes one 16-bit value to the Summit internal registers or to the device shared memory. Parameters: addr  The device base address address to write. offset  The offset of the address to write from addr in 16-bit words. data  The value to write.
