[Intel-gfx] [PATCH] drm/i915: Whitelist COMMON_SLICE_CHICKEN2

[Chris Wilson]

Quoting Kenneth Graunke (2019-09-11 02:48:01)
> This allows userspace to use "legacy" mode for push constants, where
> they are committed at 3DPRIMITIVE or flush time, rather than being
> committed at 3DSTATE_BINDING_TABLE_POINTERS_XS time.  Gen6-8 and Gen11
> both use the "legacy" behavior - only Gen9 works in the "new" way.
> 
> Conflating push constants with binding tables is painful for userspace,
> we would like to be able to avoid doing so.
