Read of sip.SEIP does not return mvip.SEIP even if mvien.SEIP = 1 & mideleg = 0

[jeffy1009]

AIA spec specifies that sip[n] is an alias of mvip[n] when mvien[n]=1 && mideleg[n]=0.

In the dev board I have, read of sip.SEIP = 0 even though mvip.SEIP=1. ( But stopi >> 16 = 0x9, and it cause S-mode to trap correctly).

The tests have be conducted in M-mode.

Could it be just implementation error?

(I'm wondering if I'm missing something from the spec)

The value of stopi.IID can be 9 only if both sip.SEIP = 1 and sie.SEIE = 1. If you are seeing stopi.IID = 9 and sip.SEIP = 0, that is an implementation error.
