From 96352eca5c7c36c3e0eb97a6d68fb170ce643ea5 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 8 May 2019 10:26:16 +0200 Subject: drm: Add VRAM MM, a simple memory manager for dedicated VRAM The VRAM MM memory manager is a helper library that manages dedicated video memory of simple framebuffer devices. It is supported to be used with struct drm_gem_vram_object, but does not depend on it. The implementation is based on the respective code from ast, bochs, and mgag200. These drivers share the exact same implementation except for type names. The helpers are currently build with TTM. This may change in future revisions. v4: * cleanups from checkpatch.pl v2: * renamed to struct drm_vram_mm * add drm_vram_mm_mmap() helper * documentation fixes Signed-off-by: Thomas Zimmermann Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-7-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann --- Documentation/gpu/drm-mm.rst | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'Documentation/gpu') diff --git a/Documentation/gpu/drm-mm.rst b/Documentation/gpu/drm-mm.rst index a3b685089512..eba50afbda42 100644 --- a/Documentation/gpu/drm-mm.rst +++ b/Documentation/gpu/drm-mm.rst @@ -79,7 +79,6 @@ count for the TTM, which will call your initialization function.
