The cursor code currently ignores fb->pitches[0] (except when creating the fb itself), and just uses the cursor_width*4 as the stride. Let's make sure fb->pitches[0] actually matches what we expect it to be. We can also relax the stride vs. cursor width relationship on 845/865 since the stride is programmed separately. The only constraint is that width*cpp doesn't exceed the stride, and that's already been checked by the core since it makes sure the entire plane fits within the fb. We can also drop the bo size check as that's already checked when we create the fb. That is the fb is guaranteed to fit within the bo. v2: Rebase due to i845_cursor_ctl() and i9xx_cursor_ctl() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> #v1 Link: http://patchwork.freedesktop.org/patch/msgid/20170327185546.2977-11-ville.syrjala@linux.intel.com |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
