The kernel prefers enabling fbc over the initial fb, since this leads to actual runtime power savings, so if the initial fb is deemed too big using some heuristic, then we simply skip allocating stolen for it. However if the kernel is not configured with fbcon then it should be possible to relax this, since unlike with fbcon the display server shouldn't preserve it when later replacing it, and so we should be able to re-use the stolen memory for fbc and friends. This patch is reported to fix some flicker seen during boot splash on some devices. v2: s/FRAMEBUFFER_CONSOLE/CONFIG_FRAMEBUFFER_CONSOLE Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Lee Shawn C <shawn.c.lee@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210526124901.245689-1-matthew.auld@intel.com |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
