Subject: [PATCH 0/3] drm: Allow simpledrm to setup its emulated FB as firmware provided
Date: Mon,  2 May 2022 10:48:27 +0200	[thread overview]
Message-ID: <20220502084830.285639-1-javierm@redhat.com> (raw)

Hello,

This series contain patches suggested by Thomas Zimmermannas a feedback for
"[RFC PATCH v4 00/11] Fix some race between sysfb device registration and
drivers probe" [0].

Since other changes in [0] were more controversial, I decided to just split
this part in a new patch-set and revisit the rest of the patches later.

Patch #1 is just a cleanup since when working on this noticed that some DRM
drivers were passing as preferred bits per pixel to drm_fbdev_generic_setup()
the value that is the default anyways.

Patch #2 renames the 'preferred_bpp' drm_fbdev_generic_setup() parameter to
'options', and make this a multi field parameter so that it can be extended
later to pass other options as well.

Patch #3 finally adds the new DRM_FB_FW option and makes simpledrm to use it
so that the registered framebuffer device is also marked as firmware provided.

Javier Martinez Canillas (3):
  drm: Remove superfluous arg when calling to drm_fbdev_generic_setup()
  drm/fb-helper: Rename preferred_bpp drm_fbdev_generic_setup()
    parameter
  drm: Allow simpledrm to setup its emulated FB as firmware provided
