[PATCH v7 3/7] drm/i915: Prepare for multiple GTs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

On a multi-tile platform, each tile has its own registers + GGTT
space, and BAR 0 is extended to cover all of them.

Up to four GTs are supported in i915->gt[], with slot zero
shadowing the existing i915->gt0 to enable source compatibility
with legacy driver paths. A for_each_gt macro is added to iterate
over the GTs and will be used by upcoming patches that convert
various parts of the driver to be multi-gt aware.

Only the primary/root tile is initialized for now; the other
tiles will be detected and plugged in by future patches once the
necessary infrastructure is in place to handle them.
