[PATCH 0/4] Allow error capture without a request / on reset failure

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

It is technically possible to get a hung context without a valid
request. In such a situation, try to provide as much information in
the error capture as possible rather than just aborting and capturing
nothing.

Similarly, in the case of an engine reset failure the GuC is not able
to report the guilty context. So try a manual search instead of
reporting nothing.
