Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

Subject: [PATCH v3] drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers
Date: Mon, 22 Feb 2021 15:17:56 +0100	[thread overview]
Message-ID: <20210222141756.7864-1-tzimmermann@suse.de> (raw)

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation
