C++ (Cpp) drm_framebuffer_read_refcount Examples

Example #1

File: msm_fb.c Project: AK101111/linux

void msm_framebuffer_describe(struct drm_framebuffer *fb, struct seq_file *m)
{
	struct msm_framebuffer *msm_fb = to_msm_framebuffer(fb);
	int i, n = drm_format_num_planes(fb->pixel_format);

	seq_printf(m, "fb: %dx%d@%4.4s (%2d, ID:%d)\n",
			fb->width, fb->height, (char *)&fb->pixel_format,
			drm_framebuffer_read_refcount(fb), fb->base.id);

	for (i = 0; i < n; i++) {
		seq_printf(m, "   %d: offset=%d pitch=%d, obj: ",
				i, fb->offsets[i], fb->pitches[i]);
		msm_gem_describe(msm_fb->planes[i], m);
	}
}
