[Nouveau] [RFC PATCH v4 0/3] Add support modifiers for drivers whose planes only support linear layout

[Tomohito Esaki]

Some drivers whose planes only support linear layout fb do not support format
modifiers.
These drivers should support modifiers, however the DRM core should handle this
rather than open-coding in every driver.

In this patch series, these drivers expose format modifiers based on the
following suggestion[1].

[Nouveau] [RFC PATCH v4 1/3] drm: introduce fb_modifiers_not_supported flag in mode_config

[Tomohito Esaki]

If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying buffer. Therefore, a new flag fb_modifiers_not_supported is
introduced for these legacy drivers, and allow_fb_modifiers is replaced
with this new flag.
