57  * Notes:
58  * (1) If MAXVAB is != 0, VAB_THRESH should be less than MAXVAB.
59  *
60  * (2) L2DFDBE and L2DFSBE allows software to generate L2DSBE, L2DDBE, VBFSBE,
61  * and VBFDBE errors for the purposes of testing error handling code.  When
62  * one (or both) of these bits are set a PL2 which misses in the L2 will fill
63  * with the appropriate error in the first 2 OWs of the fill. Software can
64  * determine which OW pair gets the error by choosing the desired fill order
65  * (address<6:5>).  A PL2 which hits in the L2 will not inject any errors.
66  * Therefore sending a WBIL2 prior to the PL2 is recommended to make a miss
67  * likely (if multiple processors are involved software must be careful to be
68  * sure no other processor or IO device can bring the block into the L2).
69  *
70  * To generate a VBFSBE or VBFDBE, software must first get the cache block
71  * into the cache with an error using a PL2 which misses the L2.  Then a
72  * store partial to a portion of the cache block without the error must
73  * change the block to dirty.  Then, a subsequent WBL2/WBIL2/victim will
74  * trigger the VBFSBE/VBFDBE error.
