** ARECA FIRMWARE SPEC
|
|
*******************************************************************************
|
|
** Usage of IOP331 adapter
|
|
** (All In/Out is in IOP331's view)
|
|
** 1. Message 0 --> InitThread message and return code
|
|
** 2. Doorbell is used for RS-232 emulation
|
|
** inDoorBell : bit0 -- data in ready
|
|
** (DRIVER DATA WRITE OK)
|
|
** bit1 -- data out has been read
|
|
** (DRIVER DATA READ OK)
|
|
** outDooeBell: bit0 -- data out ready
|
|
** (IOP331 DATA WRITE OK)
|
|
** bit1 -- data in has been read
|
|
** (IOP331 DATA READ OK)
|
|
** 3. Index Memory Usage
|
|
** offset 0xf00 : for RS232 out (request buffer)
|
|
** offset 0xe00 : for RS232 in (scratch buffer)
|
|
** offset 0xa00 : for inbound message code message_rwbuffer
|
|
** (driver send to IOP331)
|
|
** offset 0xa00 : for outbound message code message_rwbuffer
|
|
** (IOP331 send to driver)
|
|
** 4. RS-232 emulation
|
|
** Currently 128 byte buffer is used
|
|
** 1st uint32_t : Data length (1--124)
|
|
** Byte 4--127 : Max 124 bytes of data
|
|
** 5. PostQ
|
|
** All SCSI Command must be sent through postQ:
|
|
** (inbound queue port) Request frame must be 32 bytes aligned
|
|
** #bit27--bit31 => flag for post ccb
|
|
** #bit0--bit26 => real address (bit27--bit31) of post arcmsr_cdb
|
|
** bit31 :
|
|
** 0 : 256 bytes frame
|
|
** 1 : 512 bytes frame
|
|
** bit30 :
|
|
** 0 : normal request
|
|
** 1 : BIOS request
|
|
** bit29 : reserved
|
|
** bit28 : reserved
|
|
** bit27 : reserved
|
|
** ---------------------------------------------------------------------------
|
|
** (outbount queue port) Request reply
|
|
** #bit27--bit31
|
|
** => flag for reply
|
|
** #bit0--bit26
|
|
** => real address (bit27--bit31) of reply arcmsr_cdb
|
|
** bit31 : must be 0 (for this type of reply)
|
|
** bit30 : reserved for BIOS handshake
|
|
** bit29 : reserved
|
|
** bit28 :
|
|
** 0 : no error, ignore AdapStatus/DevStatus/SenseData
|
|
** 1 : Error, error code in AdapStatus/DevStatus/SenseData
|
|
** bit27 : reserved
|
|
** 6. BIOS request
|
|
** All BIOS request is the same with request from PostQ
|
|
** Except :
|
|
** Request frame is sent from configuration space
|
|
** offset: 0x78 : Request Frame (bit30 == 1)
|
|
** offset: 0x18 : writeonly to generate
|
|
** IRQ to IOP331
|
|
** Completion of request:
|
|
** (bit30 == 0, bit28==err flag)
|
|
** 7. Definition of SGL entry (structure)
|
|
** 8. Message1 Out - Diag Status Code (????)
|
|
** 9. Message0 message code :
|
|
** 0x00 : NOP
