[0/5] drm: Introduce DRM client library

Message

Thomas Zimmermann Sept. 27, 2024, 2:37 p.m. UTC

With the next DRM client coming soon (drm_log) and most of DRM's
fbdev emulation consolidated in a few places, it's time to provide
a single place for the clients.

The new module drm_client_lib.ko stores most of the common client
code. It's designed such that drivers can opt into client support,
but the presence of the client module depends on the user's kernel
configuration. Without selected clients, no client module will be
build.

Thomas Zimmermann (5):
  drm/i915: Select DRM_CLIENT_SELECTION
  drm/xe: Select DRM_CLIENT_SELECTION
  drm: Move client-device functions in to drm_client_dev.c
  drm: Select fbdev helpers for modules that require them
  drm: Add client-lib module
