Andrew Waterman 000cde2f8a Make ErrorDevice UNCACHEABLE instead of UNCACHED 
...even though it still supports Acquire.  This avoids needing to flush
the D$ on FENCE.I because of the presence of the ErrorDevice.
 2018-01-05 14:00:42 -08:00
Andrew Waterman ad0b9a0b1b Reduce cases in which FENCE.I must flush D$ 
Memory regions that are uncacheable or have get/put effects should not
reside in the D$, so there is no need to flush them.

coreplex: make HasTiles more generic
 2018-01-02 19:38:17 -08:00
Andrew Waterman ee1a9485df Enforce physical-address canonicalization 
When xLen > paddrBits, enforce that physical addresses are zero-extended.
This works by checking that the _virtual_ address is _sign_-extended, then
checking that its sign is positive.
 2018-01-02 18:47:30 -08:00
Andrew Waterman 7c9a1b0265 Correctly check for virtual-address canonicalization 
The previous check was necessary but not sufficient.

BaseTile now has optional LocalInterruptNode.

Andrew Waterman 676110bc1f Add cover for a1ebe6da4d 2017-12-07 21:03:42 -08:00
Andrew Waterman a1ebe6da4d Prevent frontend deadlock fetching from uncacheable memory 
After detecting a corrupted BTB, don't speculatively update it until
the next non-speculative fetch.  This prevents the frontend from replaying
forever.
