It only parses the parts of the EDID that - * are useful for developing timings and identifying the monitor. Items - * like monitor serial numbers, chromaticity settings etc. are not useful - * in the display drivers. There should be a simple interface to provide - * the complete unparsed EDID to IAL, so that such information can be - * used by a IAL driver if need be. - * - * timings_t: This is a structure that contains one set of display timings. - * It is complete in that it contains all 12 timings fields instead of - * the popular 8. Some of the "Established" EDID timings require all 12 - * fields. It also allows for both established flags and driver specific - * flags to make it flexible enough to work for most drivers. The - * EDID parser will mark the flags with FB_TIMINGS_PREFERRED if they are - * found to be listed in the EDID. This does not include modes within - * the the sync ranges (if provided), only "Established" "Standard" and - * "Detailed" timings. - * - * edid_t: This structure will be populated by the EDID parser. There - * are three important areas of information that impact display timings. - * The h_max,h_min,v_max,v_min represent the range of timings that the - * display is capable of accepting. No timings outside this range should - * be used by the driver if a range is provided. - * - * Any "Detailed" timings will be fully parsed and returned in - * the timings array (only the first 12 are parsed, it is very unlikely - * that any EDID exist that contain this many). - * - * Suggested driver behavior when setting display timings would be to - * first attempt to use "Detailed" timings provided by the monitor. Then - * attempt to use the "Standard" timings that were marked as PREFERRED, - * then as a last alternative, use a nonstandard set of timings within - * the provided range. - * - */ - -#ifndef _EDID_H -#define _EDID_H - -#include <displayid.h> -#include <pd.h> - -/* This structure holds all of the parsed EDID information.*/ -#define NUM_TIMINGS 12 - -/* EDID return values */ -#define EDID_ERROR_PARSE 1 -#define EDID_READ_AGAIN 2 - -typedef struct _established_timing { - unsigned long width; - unsigned long height; - unsigned long refresh; -} established_timing_t; - -typedef struct _edid { - unsigned char version; /* Edid Version */ - unsigned char revision; /* Edid Revision */ - char vendor[4]; /* Vendor Name code */ - unsigned long product_code; /* Vendor assigned code */ - unsigned long serial_number; /* 32-bit serial number */ - unsigned char manf_week; /* Manufactored week number */ - unsigned long manf_year; /* Manufactored year */ - unsigned char standard_color; - unsigned char preferred_timing; /* Use first timing Provided */ - unsigned char dpms; - unsigned char display_type; - unsigned char gtf; - unsigned char range_set; /* EDID Contains Valid Range Data */ - timing_range_t range; - unsigned char num_timings; - pd_timing_t timings[NUM_TIMINGS]; - char name[14]; - cea_extension_t *cea; /* CEA extension based on 861-B */ -} edid_t; - -/* Functions */ -int edid_parse( - unsigned char *buffer, - edid_t *edid, - pd_timing_t *timings, - int count, - unsigned char upscale); - -void enable_disable_timings(pd_timing_t *timing, unsigned char enable); -void enable_scaled_timings(pd_timing_t *timing, pd_timing_t *dtd, - unsigned char upscale); -void firmware_dump(unsigned char *buffer, unsigned short size); -void edid_print(edid_t *edid); - -int edid_ext_parse( - unsigned char *buffer, - edid_t *edid, - pd_timing_t *timings, - int count, - unsigned char upscale); -#endif -/*---------------------------------------------------------------------------- - * File Revision History - * $Id: edid.h,v 1.3 2010/07/23 16:54:50 bpaauwe Exp $ - * $Source: /nfs/fm/proj/eia/cvsroot/koheo/linux/egd_drm/emgd/include/edid.h,v $ - *---------------------------------------------------------------------------- - */ |
