From ba282daa919f89c871780f344a71e5403a70b634 Mon Sep 17 00:00:00 2001 From: Raphael Assenat Date: Tue, 16 Oct 2007 01:28:40 -0700 Subject: mbxfb: Improvements and new features This contains the following changes: * Overlay surface alpha is configured separately from the overlay. This prevents display glitches (configure and fill the overlay first, set alpha to a visible value next) * Added an ioctl for configuring transparency of the Overlay and graphics planes. Blend mode, colorkey mode and global alpha mode are supported. * Added an ioctl for setting the plane order. The overlay plance can be placed over or under the graphics plane. * Added an ioctl for setting and reading chip registers, with mask. * Updated copyright for 2007 [adaplas] * Coding style changes Signed-off-by: Raphael Assenat Signed-off-by: Antonino Daplas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/video/mbxfb.h | 53 ++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 46 insertions(+), 7 deletions(-) (limited to 'include/video') diff --git a/include/video/mbxfb.h b/include/video/mbxfb.h index 20b9002712ef..ea18961fc5e7 100644 --- a/include/video/mbxfb.h +++ b/include/video/mbxfb.h @@ -29,18 +29,18 @@ struct mbxfb_platform_data { }; /* planar */ -#define MBXFB_FMT_YUV12 0 +#define MBXFB_FMT_YUV16 0 +#define MBXFB_FMT_YUV12 1 /* packed */ -#define MBXFB_FMT_UY0VY1 1 -#define MBXFB_FMT_VY0UY1 2 -#define MBXFB_FMT_Y0UY1V 3 -#define MBXFB_FMT_Y0VY1U 4 +#define MBXFB_FMT_UY0VY1 2 +#define MBXFB_FMT_VY0UY1 3 +#define MBXFB_FMT_Y0UY1V 4 +#define MBXFB_FMT_Y0VY1U 5 struct mbxfb_overlaySetup { __u32 enable; __u32 x, y; __u32 width, height; - __u32 alpha; __u32 fmt; __u32 mem_offset; __u32 scaled_width; @@ -54,6 +54,45 @@ struct mbxfb_overlaySetup { __u16 UV_stride; }; -#define MBXFB_IOCX_OVERLAY _IOWR(0xF4, 0x00,struct mbxfb_overlaySetup) +#define MBXFB_ALPHABLEND_NONE 0 +#define MBXFB_ALPHABLEND_GLOBAL 1 +#define MBXFB_ALPHABLEND_PIXEL 2 + +#define MBXFB_COLORKEY_DISABLED 0 +#define MBXFB_COLORKEY_PREVIOUS 1 +#define MBXFB_COLORKEY_CURRENT 2 +struct mbxfb_alphaCtl { + __u8 overlay_blend_mode; + __u8 overlay_colorkey_mode; + __u8 overlay_global_alpha; + __u32 overlay_colorkey; + __u32 overlay_colorkey_mask; + + __u8 graphics_blend_mode; + __u8 graphics_colorkey_mode; + __u8 graphics_global_alpha; + __u32 graphics_colorkey; + __u32 graphics_colorkey_mask; +}; + +#define MBXFB_PLANE_GRAPHICS 0 +#define MBXFB_PLANE_VIDEO 1 +struct mbxfb_planeorder { + __u8 bottom; + __u8 top; +}; + +struct mbxfb_reg { + __u32 addr; /* offset from 0x03fe 0000 */ + __u32 val; /* value */ + __u32 mask; /* which bits to touch (for write) */ +}; + +#define MBXFB_IOCX_OVERLAY _IOWR(0xF4, 0x00,struct mbxfb_overlaySetup) +#define MBXFB_IOCG_ALPHA _IOR(0xF4, 0x01,struct mbxfb_alphaCtl) +#define MBXFB_IOCS_ALPHA _IOW(0xF4, 0x02,struct mbxfb_alphaCtl) +#define MBXFB_IOCS_PLANEORDER _IOR(0xF4, 0x03,struct mbxfb_planeorder) +#define MBXFB_IOCS_REG _IOW(0xF4, 0x04,struct mbxfb_reg) +#define MBXFB_IOCX_REG _IOWR(0xF4, 0x05,struct mbxfb_reg) #endif /* __MBX_FB_H */ -- cgit v1.2.3-59-g8ed1b
