Hi,

Il will send this series as a PATCH v3 after the two round of
RFCs[1, 2].

In this patchset I propose an alternative way of engine discovery
thanks to the new interfaces developed by Tvrtko and Chris[3].

Thanks Chris and Tvrtko for your comments in the RFC.

V1 --> V2
=========
RFC v1: [1]
- added a demo test that simply queries the driver about the
engines and executes a buffer (thanks Tvrtko)
- refactored the for_each_engine_ctx() macro so that what in the
previous version was done by the "bind" function, now it's done
in the first iteration. (Thanks Crhis)
- removed the "gem_has_ring_ctx()" because it was out of the
scope.
- rename functions to more meaningful names

V2 -- V3
========
RFC v2: [2]
- removed a standalone gem_query_engines_demo test and added the
exec-ctx subtest inside gem_exec_basic (thanks Tvrtko).
- fixed most of Tvrtko's comments in [4], which consist in
putting the mallocs igt_assert and ictls in igt_require and few
refactoring (thanks Tvrtko).
