Add initial vesa modes even if EDID information is present. EDID does not
include all supported video modes. Fixes #4166.

Note that this change will probably show several weird resolution is some
configurations. They are all valid resolutions but are not commom so we need
a way to filter those out.

* Add the width, and height to fill_display_mode(). This should help with #7751
this time.

Fix crash in VESA accelerant.

- Keep track of the correct number of initial modes available.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42438 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed coding style violation introduced with the last commit.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42429 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Only add the VESA modes if there is no EDID available.

* The VESA accelerant now always makes sure that all supported resolutions are
added to the mode list (in 60 Hz, but that doesn't really matter).
* It does this by iterating over the modes found, and computes the
display_timings from them using the GTF code.
* This should help with one of the problems of ticket #7751.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42421 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added VESA capabilities field to the kernel args.
* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

* If the VESA accelerant has EDID information, it will now also pass it to
create_display_modes().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32020 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added DPMS support to the VESA driver, in case the hardware/BIOS supports it.
* Minor cleanup.

* The boot loader now passes on its EDID info to the kernel, and that will
be put into a boot_item in frame_buffer_console_init().
* The VESA driver now supports gettings the EDID information as well; this
is necessary now, since the app_server no longer takes over the mode the
boot loader had chosen.
* Note, we might want to do this via vm86 instead in the future, and remove
the kernel part again.

Patch by Jan Klötzke with minor changes by myself:
* Use vm86 mode to call the VESA BIOS to do the actual mode switching by
providing an ioctl in the vesa driver.
* Fix vm86.h.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25680 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed get_boot_item() API: it now also can retrieve the size of the boot
item entry.
* The bios_ia32 video platform code now stores the available VESA modes in
the new vesa_modes kernel_args field.
* When configuring a VESA mode via settings file, it's no longer needed to
specify the exact mode - the closest available mode is now used. This should
help with bug #1962.
* frame_buffer_console_init() now also creates a boot_item for the VESA modes
in the kernel_args.
* The VESA accelerant now filters the mode list to only contain modes that
are actually supported.
* Moved non-shared vesa driver data into its own file vesa_private.h.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24675 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Now completely initializes the current_mode if it's in the mode list.
* The mode list is now created by the common mode list creation code.
* Minor cleanup.

* Moved VGA planar mode blitting into the VESA kernel driver.
* In grayscale mode, the AccelerantHWInterface now sets the palette correctly.
* HWInterface now has a fVGADevice set by AccelerantHWInterface which will be used
to talk to the VESA driver.
* Completed planar blitting for all 4 planes; we now have a perfect 16 color
grayscale mode when you choose "Standard VGA mode" in the boot loader with
an unsupported graphics card (such as in Qemu).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19567 a95241bf-73f2-0310-859d-f6bbb57e9c96

Calmed down the VESA accelerant a bit.

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

Made some necessary enhancements to class Screen; the app_server also
has to care about refresh rates. Also changed Screen::GetMode() (formerly
Resolution()) to return all interesting values, so that hopefully no one
will call it anymore like RootLayer::SetScreens() did.
Greatly improved the horrible RootLayer::SetScreens().
The app_server is now able to deal with failing HWInterface::SetMode() calls;
in this case, it will fall back to the hardware's current mode. This now
also works correctly in combination with the vesa driver, so that you don't
have to compile the app_server with the same resolution you boot in anymore.
SetMode() now always returns if it succeeded or not.
Renamed RootLayer::fScreenXYResolution to fScreenWidth/Height respectively.
Removed the useless DisplayDriver::DisplayMode() method.
Added B_GET_DISPLAY_MODE to the required accelerant hooks.
Some minor cleanup.

Added very basic VESA driver. Will be improved in the future (right now
it doesn't really do anything, it just passes the initial frame buffer
on to the app_server).
While it seems to work on real hardware (if you set the video mode to
640x480x32, app_server restriction), under Bochs, the app_server crashes.
