Subject: [PATCH 00/25] drm: fb emulation: Step 1: Create new drm_fb_helper wrapper funcs
Date: Mon, 13 Jul 2015 12:07:56 +0530 [thread overview]
Message-ID: <1436769501-4105-1-git-send-email-architt@codeaurora.org> (raw)
DRM drivers using drm_fb_helpers still call some fbdev core functions.
This makes the driver depend on CONFIG_FB, resulting in complicated
Kconfig options, and preventing us from creating a top level drm config
option to enable/disable FBDEV emulation.
Create new drm_fb_helper functions that replace these fbdev functions.
In most cases, the new helper funcs simply wrap around the original fbdev
functions. For a few (like framebufer_alloc), we actually do some work
that is currently redundant across multiple drivers.
With these patches, the drivers don't call any fbdev functions directly.
They are now called through functions in drm_fb_helper.c. We will later
create a fbdev emulation config option to stub out the fb helpers.
The only exception is vmwgfx driver. This doesn't use drm_fb_helper. It
creates a fb device how a driver in drivers/video/fbdev would. Maybe this
needs to be converted to use drm_fb_helpers.
For more info, have a look at the threads:
