[CI 1/3] drm/i915: Check for a second VCS engine more carefully

[CI 1/3] drm/i915: Check for a second VCS engine more carefully

[Chris Wilson]

To use the legacy BSD selector, you must have a second VCS engine, or
else the ABI simply maps the request for another engine onto VCS0.
However, we only checked a single VCS1 location and overlooking the
possibility of a sparse VCS set being mapped to the dense ABI.

v2: num_vcs_engines() turns out to be reusable and futureproof it so we
never have to worry about this silly bit of ABI again!

[CI 2/3] drm/i915: Replace global bsd_dispatch_index with random seed

[Chris Wilson]

We keep a global seed for the legacy BSD round-robin selector, but in
our testing of multiple simultaneous client workloads, a random seed
spreads the load more evenly. (As even as an initial round-robin selector
can be!) Removing the global is one less variable we have to find a home
for!

We can simulate multi-client (both same and mixed workloads) using
igt/gem_wsim to work out optimal strategies and then compare our
simulation with the actual transcoder on multi-engine machines. This
fixed round-robin turns out to be one of the worst methods.

No user is advised to use this method; the current suggestion is to use
a virtual engine for agnostic batches, randomised submission or using
the busyness tracking to select the most idle engine at the time of
dispatch. At the present time, intel-media is explicit, but libva still
seems to use it, with the exception of batches that must execute on vcs0.
Oh well.

[CI 3/3] drm/i915: Generalise BSD default selection

[Chris Wilson]

For the default I915_EXEC_BSD round robin selector, it may select any
available VCS engine. Make it so.

[PATCH] drm/i915: Check for a second VCS engine more carefully

[Chris Wilson]

To use the legacy BSD selector, you must have a second VCS engine, or
else the ABI simply maps the request for another engine onto VCS0.
However, we only checked a single VCS1 location and overlooking the
possibility of a sparse VCS set being mapped to the dense ABI.

v2: num_vcs_engines() turns out to be reusable and futureproof it so we
never have to worry about this silly bit of ABI again!

Off-by-one in the VCS mask, we don't want to include VECS0!
