* 0xc{0,2}3c*, 0x60{1,3}3*, and 0x68{1,3}3d*
|

|
* in general, the set value of cr44 does not matter: reg access works as
|
||
|
|
* expected and values can be set for the appropriate head by using a 0x2000
|

* offset as required
|

* however:
|

|
|
* a) pre nv40, the head B range of PRMVIO regs at 0xc23c* was not exposed and
|

|
|
* cr44 must be set to 0 or 3 for accessing values on the correct head
|
||
|
|
* through the common 0xc03c* addresses
|
||
|
|
* b) in tied mode (4) head B is programmed to the values set on head A, and
|
||
|
|
* access using the head B addresses can have strange results, ergo we leave
|
||
|
|
* tied mode in init once we know to what cr44 should be restored on exit
|
||
|
|
*
|
||
|
|
* the owner parameter is slightly abused:
|
||
|
|
* 0 and 1 are treated as head values and so the set value is (owner * 3)
|
||
|
|
* other values are treated as literal values to set
