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
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.

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.

The previous check was necessary but not sufficient.

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.

b8098d18be diplomacy: remove the :=? operator in favour of magic :*=* (#1139)
The reason for the :=? operator was for when you have an adapter chain
whose direction of cardinality you could not know. We used explicit
directives to tell these compositions which way to go.

Unfortunately, that makes the API leaky. You think the chain of adapters
is just one adapter, but you have to use strange Cardinality scopes to
use it. That's just bad.

The new :*=* just automagically figures it out from the graph.
