The simpler way to do this is to add a line to: arch/arc/include/asm/Kbuild: + generic-y += video.h While touching the file I suggest to move to the simpler way using the Kbuild file. The same goes for all the other video.h files that only picks the asm-generic variant. > diff --git a/arch/arm/include/asm/fb.h b/arch/arm/include/asm/fb.h > deleted file mode 100644 > index ce20a43c30339..0000000000000 > --- a/arch/arm/include/asm/fb.h > +++ /dev/null > @@ -1,6 +0,0 @@ > -#ifndef _ASM_FB_H_ > -#define _ASM_FB_H_ > - > -#include <asm-generic/fb.h> > - > -#endif /* _ASM_FB_H_ */ > diff --git a/arch/arm/include/asm/video.h b/arch/arm/include/asm/video.h > new file mode 100644 > index 0000000000000..f570565366e67 > --- /dev/null > +++ b/arch/arm/include/asm/video.h > @@ -0,0 +1,6 @@ > +#ifndef _ASM_VIDEO_H_ > +#define _ASM_VIDEO_H_ > + > +#include <asm-generic/video.h> > + > +#endif /* _ASM_VIDEO_H_ */ > diff --git a/arch/arm64/include/asm/fb.h b/arch/arm64/include/asm/fb.h > deleted file mode 100644 > index 1a495d8fb2ce0..0000000000000 > --- a/arch/arm64/include/asm/fb.h > +++ /dev/null > @@ -1,10 +0,0 @@ > -/* SPDX-License-Identifier: GPL-2.0-only */ > -/* > - * Copyright (C) 2012 ARM Ltd. > - */ > -#ifndef __ASM_FB_H_ > -#define __ASM_FB_H_ > - > -#include <asm-generic/fb.h> > - > -#endif /* __ASM_FB_H_ */ > diff --git a/arch/arm64/include/asm/video.h b/arch/arm64/include/asm/video.h > new file mode 100644 > index 0000000000000..fe0e74983f4d9 > --- /dev/null > +++ b/arch/arm64/include/asm/video.h > @@ -0,0 +1,10 @@ > +/* SPDX-License-Identifier: GPL-2.0-only */ > +/* > + * Copyright (C) 2012 ARM Ltd. > + */ > +#ifndef __ASM_VIDEO_H_ > +#define __ASM_VIDEO_H_ > + > +#include <asm-generic/video.h> > + > +#endif /* __ASM_VIDEO_H_ */ > diff --git a/arch/loongarch/include/asm/fb.h b/arch/loongarch/include/asm/video.h > similarity index 86% > rename from arch/loongarch/include/asm/fb.h > rename to arch/loongarch/include/asm/video.h > index 0b218b10a9ec3..9f76845f2d4fd 100644 > --- a/arch/loongarch/include/asm/fb.h > +++ b/arch/loongarch/include/asm/video.h > @@ -2,8 +2,8 @@ > /* > * Copyright (C) 2020-2022 Loongson Technology Corporation Limited > */ > -#ifndef _ASM_FB_H_ > -#define _ASM_FB_H_ > +#ifndef _ASM_VIDEO_H_ > +#define _ASM_VIDEO_H_ > > #include <linux/compiler.h> > #include <linux/string.h> > @@ -26,6 +26,6 @@ static inline void fb_memset_io(volatile void __iomem *addr, int c, size_t n) > } > #define fb_memset fb_memset_io > > -#include <asm-generic/fb.h> > +#include <asm-generic/video.h> > > -#endif /* _ASM_FB_H_ */ > +#endif /* _ASM_VIDEO_H_ */ > diff --git a/arch/m68k/include/asm/fb.h b/arch/m68k/include/asm/video.h > similarity index 86% > rename from arch/m68k/include/asm/fb.h > rename to arch/m68k/include/asm/video.h > index 9941b7434b696..6cf2194c413d8 100644 > --- a/arch/m68k/include/asm/fb.h > +++ b/arch/m68k/include/asm/video.h > @@ -1,6 +1,6 @@ > /* SPDX-License-Identifier: GPL-2.0 */ > -#ifndef _ASM_FB_H_ > -#define _ASM_FB_H_ > +#ifndef _ASM_VIDEO_H_ > +#define _ASM_VIDEO_H_ > > #include <asm/page.h> > #include <asm/setup.h> > @@ -27,6 +27,6 @@ static inline pgprot_t pgprot_framebuffer(pgprot_t prot, > } > #define pgprot_framebuffer pgprot_framebuffer > > -#include <asm-generic/fb.h> > +#include <asm-generic/video.h> > > -#endif /* _ASM_FB_H_ */ > +#endif /* _ASM_VIDEO_H_ */ > diff --git a/arch/mips/include/asm/fb.h b/arch/mips/include/asm/video.h > similarity index 76% > rename from arch/mips/include/asm/fb.h > rename to arch/mips/include/asm/video.h > index d98d6681d64ec..007c106d980fd 100644 > --- a/arch/mips/include/asm/fb.h > +++ b/arch/mips/include/asm/video.h > @@ -1,5 +1,5 @@ > -#ifndef _ASM_FB_H_ > -#define _ASM_FB_H_ > +#ifndef _ASM_VIDEO_H_ > +#define _ASM_VIDEO_H_ > > #include <asm/page.h> > > @@ -13,8 +13,8 @@ static inline pgprot_t pgprot_framebuffer(pgprot_t prot, > > /* > * MIPS doesn't define __raw_ I/O macros, so the helpers > - * in <asm-generic/fb.h> don't generate fb_readq() and > - * fb_write().

The per-architecture fbdev code has no dependencies on fbdev and can be used for any video-related subsystem. Rename the files to 'video'. Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE. Further update all includes statements, includ guards, and Makefiles. Also update a few strings and comments to refer to video instead of fbdev.
