int __init mxcfb_init | ( | void | ) |
Main entry function for the framebuffer. The function registers the power management callback functions with the kernel and also registers the MXCFB callback functions with the core Linux framebuffer driver fbmem.c
static struct fb_info* mxcfb_init_fbinfo | ( | struct device * | dev, | |
struct fb_ops * | ops | |||
) | [static, read] |
Initializes the framebuffer information pointer. After allocating sufficient memory for the framebuffer structure, the fields are filled with custom information passed in from the configurable structures. This includes information such as bits per pixel, color maps, screen width/height and RGBA offsets.

static int mxcfb_map_video_memory | ( | struct fb_info * | fbi, | |
bool | use_internal_ram | |||
) | [static] |
Allocates the DRAM memory for the frame buffer. This buffer is remapped into a non-cached, non-buffered, memory region to allow palette and pixel writes to occur without flushing the cache. Once this area is remapped, all virtual memory access to the video memory should occur at the new region.
fbi | framebuffer information pointer | |
use_internal_ram | flag on whether to use internal RAM for memory |
static int mxcfb_probe | ( | struct platform_device * | pdev | ) | [static] |
Probe routine for the framebuffer driver. It is called during the driver binding process. The following functions are performed in this routine: Framebuffer initialization, Memory allocation and mapping, Framebuffer registration, IPU initialization.

static int mxcfb_unmap_video_memory | ( | struct fb_info * | fbi | ) | [static] |
De-allocates the DRAM memory for the frame buffer.

{ .driver = { .name = MXCFB_NAME, }, .probe = mxcfb_probe, .suspend = mxcfb_suspend, .resume = mxcfb_resume, }
This structure contains pointers to the power management callback functions.
struct fb_ops mxcfb_ops [static] |
{ .owner = THIS_MODULE, .fb_set_par = mxcfb_set_par, .fb_check_var = mxcfb_check_var, .fb_setcolreg = mxcfb_setcolreg, .fb_pan_display = mxcfb_pan_display, .fb_ioctl = mxcfb_ioctl, .fb_fillrect = cfb_fillrect, .fb_copyarea = cfb_copyarea, .fb_imageblit = cfb_imageblit, .fb_blank = mxcfb_blank, }
This structure contains the pointers to the control functions that are invoked by the core framebuffer driver to perform operations like blitting, rectangle filling, copy regions and cursor definition.
