[PATCH 0/8] drm/fb-helper: Use drm_file to get a dumb framebuffer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I want to start out by saying that this patchset is low priority for me
and if no one has interest or time to review this, that is just fine. I
was in the flow and just typed it out.

This patchset adds a way for fbdev emulation code to create a
framebuffer that is backed by a dumb buffer. drm_fb_helper gets a
drm_file to hang the objects on, drm_framebuffer_create_dumb() creates
the framebuffer and drm_fb_helper_fini() destroys it.
I have verified that all cma drivers supports dumb buffers, so
converting the library should be fine for all.

A patch by David Herrmann from a year ago made this easy. It was the
last piece in his work to make it possible to create a drm_file for
in-kernel use, but it never got merged.

I've cc'ed intel-gfx since that will give CI runs of the core patches if
I understood Daniel right.

Noralf.
