drm/vboxvideo: Use drm_gem_fb_create_with_dirty instead of drm_gem_fb_create

2019-10-29T12:10:07+00:00

Commit 7d79aa8628fe ("drm/vboxvideo: Replace struct vram_framebuffer with generic implemenation") removed the diy framebuffer code from the vboxvideo driver, resulting in a nice cleanup. But since the vboxvideo driver needs the generic dirty tracking code, it's drm_mode_config_funcs.fb_create should be set to drm_gem_fb_create_with_dirty not drm_gem_fb_create. This commit fixes this, fixing the framebuffer not always updating.

drm/vboxvideo: Replace prepare_fb()/cleanup_fb() with GEM VRAM helpers

2019-10-24T14:12:42+00:00

GEM VRAM provides an implementation for prepare_fb() and cleanup_fb() of struct drm_plane_helper_funcs. Switch over vboxvideo. Signed-off-by: Thomas Zimmermann Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20191024081404.6978-5-tzimmermann@suse.de

drm/vram: drop DRM_VRAM_MM_FILE_OPERATIONS

drm/vboxvideo: Replace struct vram_framebuffer with generic implemenation

2019-10-16T07:58:59+00:00

The vboxvideo driver's struct vram_framebuffer stores a DRM framebuffer with an assiciated GEM object. This functionality is also provided by generic code. Switch vboxvideo over.

drm/vboxvideo: Switch to drm_atomic_helper_dirty_fb()

2019-10-16T07:58:53+00:00

The vboxvideo driver provides struct drm_framebuffer_funcs.dirty_fb from its own implementation. Switch over to drm_atomic_helper_dirty_fb() and handle screen updates in the primary plane's atomic_update function. With dirty_fb out of the way, we can further replace struct vbox_frammebuffer with generic code.

drm/vboxvideo: Switch to generic fbdev emulation

There's nothing special about vboxvideo's fbdev emulation that is not provided by the generic implementation. Switch over and remove the driver's code.

drm/vram: Have VRAM MM call GEM VRAM functions directly

2019-09-12T17:54:42+00:00

VRAM MM and GEM VRAM buffer objects are only used with each other; connected via 3 function pointers. Simplify this code by making the memory manager call the rsp. functions of the BOs directly; and remove the functions from the BO's public interface. v2: * typos in commit message Signed-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20190911110910.30698-3-tzimmermann@suse.de

drm/vram: Move VRAM memory manager to GEM VRAM implementation

2019-09-12T17:54:04+00:00

The separation between GEM VRAM objects and the memory manager is artificial, as they are only used with each other. Copying both implementations into the same file is a first step to simplifying the code. This patch only moves code without functional changes. v3: * update to use dev->vma_offset_manager v2: * update for debugfs support * typos in commit message Signed-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20190911110910.30698-2-tzimmermann@suse.de

drm/vboxvideo: Make structure vbox_fb_helper_funcs constant

2019-08-18T10:52:52+00:00

The static structure vbox_fb_helper_funcs, of type drm_fb_helper_funcs, is used only when it is passed as the third argument to drm_fb_helper_fbdev_setup(), which does not modify it. Hence make it constant to protect it from unintended modifications. Issue found with Coccinelle.
