* Notes:
|
|
* (1) If MAXVAB is != 0, VAB_THRESH should be less than MAXVAB.
|
|
*
|
|
* (2) L2DFDBE and L2DFSBE allows software to generate L2DSBE, L2DDBE, VBFSBE,
|
|
* and VBFDBE errors for the purposes of testing error handling code. When
|
|
* one (or both) of these bits are set a PL2 which misses in the L2 will fill
|
|
* with the appropriate error in the first 2 OWs of the fill. Software can
|
|
* determine which OW pair gets the error by choosing the desired fill order
|
|
* (address<6:5>). A PL2 which hits in the L2 will not inject any errors.
|
|
* Therefore sending a WBIL2 prior to the PL2 is recommended to make a miss
|
|
* likely (if multiple processors are involved software must be careful to be
|
|
* sure no other processor or IO device can bring the block into the L2).
|
|
*
|
|
* To generate a VBFSBE or VBFDBE, software must first get the cache block
|
|
* into the cache with an error using a PL2 which misses the L2. Then a
|
|
* store partial to a portion of the cache block without the error must
|
|
* change the block to dirty. Then, a subsequent WBL2/WBIL2/victim will
|
|
* trigger the VBFSBE/VBFDBE error.
