lib: Add an intel_ctx wrapper struct and helpers (v6)
We're trying to clean up some of our technical debt in the i915 API. In
particular, context mutability and unnecessary getparam(). There's
quite a bit of the introspection stuff that's not used by any userspace
other than IGT. Most drivers don't care about fetching the set of
engines, for instance, because they don't forget about what set of
engines they asked for int the first place.
Unfortunately, IGT relies heavily on context introspection for just
about everything when it comes to multi-engine testing. It also likes
to use ctx0 as temporary storage for whatever the current test config
is. While effective at keeping IGC simple in some ways, this means
we're making heavy use of context mutability. Also, passing data around
with in tests isn't really what contexts are for.
This patch adds a new intel_ctx_t struct which wraps a context and
remembers the full context configuration. This will provide similar
ease-of-use without having use ctx0 as temporary storage.
v2 (Jason Ekstrand):
- Make all intel_ctx_t's const
v3 (Jason Ekstrand):
- Fix up the docs so they build properly
v4 (Jason Ekstrand):
- Add an intel_ctx_create_for_engine helper
v5 (Zbigniew Kempczyński):
- Use SPDX license identifiers
- Document default context semantics
v6 (Ashutosh Dixit):
- Fix SPDX in intel_ctx.h
- Fix a typo in a comment
v6 (Jason Ekstrand):
- Add documentation about num_engines to intel_ctx_cfg_t
