Axel Dörfler 030d964e4e Made the primary ring buffer for the acceleration commands a bit larger (16 KB); 
this is mostly done because of the fact that I haven't tested how full it usually
is, and since I haven't implemented checking for free space yet...

Axel Dörfler e3fe0cd725 This didn't even read out the page table register, it read something from address 
0x2020, which resulted in a page fault under Haiku.

Axel Dörfler 08ef16abee * Now allocates space for the hardware status page and cursor memory, not yet 
used, though.
* Renamed the PhyisicalPageMapper class to AreaKeeper and made it a bit more
  generic (ie. it can now also create usual areas)
* The shared_info is now created using the AreaKeeper, too, and this actually
  fixes some potential memory leaks.

Axel Dörfler 96451fe133 We're now using a secondary (high priority) ring buffer for hardware 
overlay - this will improve the overlay performance when the engine is
under load (the acceleration engine will use the primary lower priority
ring buffer).

Axel Dörfler 18f48919c0 This little fix should allow Stippi to have a working driver when he compiled 
it himself.

Axel Dörfler f197302867 The size of the stolen memory for the graphics chip is now read out of the host bridge.

Axel Dörfler 2465e30305 Accidently set the contrast too low, overlay now looks just fine.

Axel Dörfler 7740a4c15b Enabling overlay requires a command ring buffer, and we're setting one (very 
small) up for this specific task - this will later be used for the acceleration
engine as well.
Some more work on overlay initialization, doesn't do anything yet, though.

Axel Dörfler 22d4db9280 * Added overlay register definitions. 
* The overlay register update buffer is now created and exported, ready
  to be used.

Axel Dörfler 5da6291b99 * Now using Thomas memory manager to manage the graphics memory; allocation 
of graphics memory is now possible.
* Changed driver name to start with "intel_extreme" to have a nicer device
  name.
* Renamed frame_buffer* stuff to graphics_memory* as the frame buffer just
  happens to be located somewhere in the graphics memory.

Axel Dörfler 020c1aa823 * init_driver() now behaves better in low memory situations. 
* Some preparations to support more than one chipset, added i855G (device ID 0x3582)
  to test with - the accelerant_device_info is now filled with that additional data
  as well.
* Some minor cleanup.

Axel Dörfler 7a3806ce87 Now you can also select the refresh rate you like under R5. Looks like there is 
room for improvements left in our screen preferences application, which ignores
the pixel clock values completely.

Axel Dörfler 943578b15b Added some debug output - the driver is actually working under R5 as well, I just 
didn't test it correctly last time...

Axel Dörfler e404297e56 Very basic driver for the "Intel Extreme Graphics 2" chips, only supports i865G for now. 
Only mode switches do work, doesn't yet make sure the mode is valid, though.
At this point, this driver only works on Haiku, the R5 app_server is crashing for some
reason I need to investigate some day (maybe tomorrow :)).
