/*
|
||||
* 1/26/2006
|
||||
*
|
||||
* WAR for SGI PV 944642. For revA TIOCE, need to use the following recipe
|
||||
* (taken from the above PV) before and after accessing tioce internal MMR's
|
||||
* to avoid tioce lockups.
|
||||
*
|
||||
* The recipe as taken from the PV:
|
||||
*
|
||||
* if(mmr address < 0x45000) {
|
||||
* if(mmr address == 0 or 0x80)
|
||||
* mmr wrt or read address 0xc0
|
||||
* else if(mmr address == 0x148 or 0x200)
|
||||
* mmr wrt or read address 0x28
|
||||
* else
|
||||
* mmr wrt or read address 0x158
|
||||
*
|
||||
* do desired mmr access (rd or wrt)
|
||||
*
|
||||
* if(mmr address == 0x100)
|
||||
* mmr wrt or read address 0x38
|
||||
* mmr wrt or read address 0xb050
|
||||
* } else
|
||||
* do desired mmr access
|
||||
*
|
||||
* According to hw, we can use reads instead of writes to the above addres
|
||||
*
|
||||
* Note this WAR can only to be used for accessing internal MMR's in the
|
||||
* TIOCE Coretalk Address Range 0x0 - 0x07ff_ffff. This includes the
|
||||
* "Local CE Registers and Memories" and "PCI Compatible Config Space" address
|
||||
* spaces from table 2-1 of the "CE Programmer's Reference Overview" document.
|
||||
*
|
||||
* All registers defined in struct tioce will meet that criteria.
