Detail: c/ScrModes - Fix a bad merge causing a compute_modedescription() call to go missing. Fix Get_DTD_ASCII to avoid reading one byte too many, and to ensure the buffer is null terminated. Also strip any control characters. Improve MDF saving to return an error if the file couldn't be created, and to substitute various unsafe characters with underscores Admin: Tested on Pandaboard Version 0.46. Tagged as 'ScrModes-0_46'

Added 'CreateModeFile' instead of optional file name on ReadEDID now needs a file path for where to save the created mdf. It'll use the name in the EDID for the file name Admin: tested in iMx6 Version 0.45. Tagged as 'ScrModes-0_45'

Detail: c/ScrModes - Make sure compute_modedescription is used to initialise frame_mhz (and line_hz). Fixes bogus vertical bounds in MDF comments, and will fix order of modes as defined by sorting function modes_inorder. Also change horizontal bounds comment to use stored line_hz value instead of computing it on the fly Admin: Tested on Pandaboard Version 0.44. Tagged as 'ScrModes-0_44'

Detail: c/ScrModes: - Double-checked all the DMT timings against the spec and corrected a few mistakes in both the DMT timings list and the established timings list. - Tidied up DMT & established timing formatting a bit, made static data arrays const - Fixed preferred mode handling so that it'll forget the preferred mode if you load an MDF after reading EDID (preferred_mode->bit0 used as a cheeky flag, in preference over malloc/free). Fixes crash/bad behaviour on startup caused by returning a duff preferred mode from Service_MonitorLeadTranslation on startup. - Added sanity checks to avoid null pointer dereferences if preferred_mode or new_preferred_mode are null - Fixed preferred mode handling to work correctly with interlaced modes (fixed it to use the frame width & height instead of the field width & height) - Tweaked CVT extension block handling - swapped the "- 17" with "- 18" in order to take into account the presence of the checksum byte - Tweaked GTF calculation to round pixel_khz to nearest when calculating it. I don't think this is mentioned in the spec, but when comparing some timings against the GTF spreadsheet this fixes ScreenModes being off by 1kHz in a few cases - When outputing an MDF, don't output display range parameters if the block wasn't found - Fix MDF output of interlaced modes (frame width/height vs. field width/height), use more accurate mHz frame rate value instead of Hz one - Make GraphicsV_IICOp calls use the correct GraphicsV driver number; current_graphicsv_driver() function added to replace ad-hoc code in a couple of other places - Fix reading of extension blocks. Also tweak logic to avoid re-reading the first block. - Initialise 'thefilename' when calling parseedid so that ERR_NOMODES will display something vaguely sensible Admin: Tested on Raspberry Pi (ROM), Pandaboard (ROM), Iyonix (softload) Appears to read EDID correctly from test monitors (BenQ FP737s, BenQ FP241W, ADI TD-523N), but there are some minor discrepancies in MDF output for some modes Version 0.43.

Detail: Added several things 1) Readedid routine not called in module initialise. 2) Flag added to determine whether old loadmodefile usage, or new readedid usage. Defaults to loadmodefile mode until a readedid command with no parameters, then swirches to edid reading mode. Reverts again if loadmodefile command is used. 3) Tidied up error message when graphicsv fails to read the edid due to connectivity issues. 4) Added hex dump of edid data blocks read to end of a saved mdf file. 5) Implemented read of second ans subsequent 128 byte edid blocks, if required. Admin: tested in imx rom Version 0.41. Tagged as 'ScrModes-0_41'

Detail: For field support it is extremely helpful to determine what a customer's monitor reports. Whilst (hopefully) this module will correctly produce modes the monitor can handle and the computer generate, when that doesn't happen support types need to be able to find out why, ideally using the same exact information that is generated. So: The ReadEDID command, if called with a full file name, will now save the discovered mdf information to that file instead of loading it. The resultant mdf can be used directly, or used as the basis for further modifications. It exports additional information in the header section which may prove helpful to 'mdf tweakers'. Admin: Tested in imx rom. In 'advertised' use it is the same code as before. It is only when the filename is given to the readedid command that different paths are invoked. Further enhancements may be desirable. Version 0.40. Tagged as 'ScrModes-0_40'

This should be considered beta-quality work-in-progress code that gives us a new *command (ReadEDID) that attempts to read the list of supported display mode information from a connected monitory and configure the system for it, as if an MDF file had been loaded containing that information. Admin: Community testing is required for this feature. Please try replacing the LoadModeFile line in your !Boot.Choices.Boot.PreDesk.Configure.Monitor file with a line saying "ReadEDID". If you get a sensible looking list of modes when the machine boots, then things should be OK. If you see an error, please get in touch with ROOL on the "Bounties - ReadEDID" topic. You'll clearly need to be running a ROM with this version of ScreenModes in it! Version 0.39. Tagged as 'ScrModes-0_39'

Get the list of supported pixel formats via GraphicsV 17 if implemented, otherwise fall back to GraphicsV 8. Generate old or new style mode provider blocks as appropriate. h/modex - Update definitions for new mode provider block format, new control list items Admin: Tested in Tungsten, IOMD, OMAP3, BCM2835 ROMs Requires HdrSrc-2_38 and Kernel-5_35-4_79_2_203 Version 0.36.

New function, build_a_vidclist() allows the GraphicsV Vet_Mode entry point to be called when validating a mode, so the graphics driver can decide on a mode by mode basis whether it can be achieved. This resolves the problem where an MDF has a super set of modes that the hardware only supports a subset of. Also * Inlined inform_modefilechanged * Removed redundant CFLAGS from makefile * Made a few braces and spaces consistent with their surroundings Tested in an IOMD ROM build on a machine with and without VRAM fitted, looking in display manager that the menus are rebuilt accordingly. Fixes ticket #315. Version 0.35. Tagged as 'ScrModes-0_35'

Relax clipping of mode names 19 characters is a bit mean if you want to say "2048 x 1024 big monitor" or similar, so bumped it to 31+terminator. 100 characters for the monitor title is a bit lavish, since (in System font) display manager's title bar can only fit 33 characters, reduced to 31+terminator too. Fixes ticket #302. Version 0.34. Tagged as 'ScrModes-0_34'

Was previously for internal use only, but largely irrelevant as the majoirty of targets don't contain a VIDC, and those that do use a GraphicsV driver anyway. * CMHG and resources updated to remove the command from the command/syntax table * Don't bother probing OS_ReadSysInfo 2 for the video controller, assume it's always GraphicsV * Don't try vetting modes based on VIDC limitations (leave that to VIDC20Video module) * Don't listen to the kernel's bandwidth limit suggestion, always use INT32_MAX Also * Fix potential null pointer dereference if there's not enough RAM to build an ICONSPRITES command * Rather than setting up an atexit() handler in the module init, just use a module finalisation handler * Makefile tickled to not use Norcroft specific flags Version 0.33.

When the video controller is V_UNKNOWN (ie.not a VIDC) then an attempt will be made to validate the desired bpp via GraphicsV.That way,when the screen modes are enumerated only achievable ones are returned. Also added an iconsprites command to the loadmodefile command,so that if a sprite file exists in the same dir as the MDF it can override the default display manager icon. Version 0.30.
