# bb693d77 14-Aug-2009 Axel Dörfler <axeld@pinc-software.de>

* 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?

# bfd4c59b 05-Jun-2009 Axel Dörfler <axeld@pinc-software.de>

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

# d16ddc57 03-Jun-2008 Axel Dörfler <axeld@pinc-software.de>

* 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.

# 9f161845 28-May-2008 Axel Dörfler <axeld@pinc-software.de>

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.

# e549b218 30-Mar-2008 Axel Dörfler <axeld@pinc-software.de>

This should have been part of r24675. Not sure what happened as I specified
the path on the commit line.

# 0c6f7795 19-Dec-2006 Axel Dörfler <axeld@pinc-software.de>

* 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).

# e5b4782b 26-May-2005 Axel Dörfler <axeld@pinc-software.de>

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.

# 93ee2104 08-Apr-2005 Axel Dörfler <axeld@pinc-software.de>

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.
