we now always only use the primary ring buffer.
* Removed secondary ring buffer allocation and member fields.
* Increased size of the primary ring buffer to 65536 bytes.
* The bytes per row register is computed differently for 9xx chips.
* On G33, the overlay does not need a physical address anymore, so we
don't pass B_APERTURE_NEED_PHYSICAL to the allocation anymore for that
device.
* intel_free_memory() accidently added the aperture base to the allocation
and would therefore never free any memory.
* INTEL_RING_BUFFER_SIZE_MASK was shifted one bit to the right, didn't
cause any harm with our buffer sizes, yet, though.
* With these changes, the driver runs stable on a G33 chipset (I have not
yet tested the hardware cursor, though, it might need some work, too).
The only known issue left is that overlay flickers a bit if its buffer
is partially backed up by reserved and allocated memory.

* Now uses the AGP GART module for memory management. This greatly simplifies
the memory handling, and memory is now actually allocated on demand,
instead of a fixed size (stolen memory is not freed, though).
* The Intel GART module should now also work with older chipsets.
* No longer remove the GTT size from the stolen memory; this appears to have
been a mistake in the X driver. Not sure about the BIOS popup yet.
* The AGP module (in combination with the Intel GART module) is now mandatory
to use the Intel driver.
* Removed now superfluous settings (like memory size). Only enabling/disabling
the hardware cursor is still supported.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23781 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added some defines needed when playing with the bridge controller.

* set_gtt_entry() used the wrong index to fill the GTT - this could have never
worked correctly when you specified more memory than the amount of stolen
memory.
* Implementing maintaining resources for emulating overlay using the 3D engine
on i965. I don't yet commit the actual overlay code, as that is a) ugly, and
b) does not work yet.
* Moved AreaKeeper into its own header.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23709 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented mapping the GTT area for i9xx chips other than the i965. This should also fix the
driver working with these chips at all.
* The memory used by the driver now take the GTT area into account - before the GTT could be
overwritten theoretically...
* Added fix for some i965 quirks from the X driver.
* Added some overlay definitions for the i965.
* Started support for G33 overlay (not complete yet).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23220 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented MakeSpace() (not yet tested).
* Changed intel_wait_engine_idle() to spin() between reads and to timeout
after 1 second of waiting (could probably be done way earlier).

acceleration works fine, but overlay doesn't - that's next on my list.
Turns out the i965 differentiates between RGB-32 and RGB-32-alpha, and
didn't like trying to use the latter as display mode (the i865 didn't
care at all)... finding that took me *way* too long, though.

will happen on earlier i9xx chips for now...). Not yet tested.

not take the VCO limits into account; both could (and would during testing) create invalid
frequencies.
* Also reverted the order in which the PLL divisors are traversed to match the order of what
is used in the X driver to create comparable output (our error computation is based on float,
though, and should therefore create more accurate values).
* The i965 introduced a special register for the surface; the former display base register
is now only used for the view offset. Instead of setting the base manually here and there,
there is now a set_frame_buffer_base() function.
* The DPMS code will now also turn off/on the PLL clock generator.
* The code needs some more cleanup, and while the driver now produces the correct timing on
my i965 system, I'm now greeted by a black screen after startup.

* Got rid of this superfluous cookie stuff - either the VFS behaves correctly, or
we're screwed anyway.
* Made adding debugger commands optional depending on if DEBUG_COMMANDS is defined
or not.
* Minor other cleanup.

doesn't work on i965 yet.
* B_GET_DISPLAY_MODE now returns the mode actually configured in the chip instead
of the last mode set; while this isn't really necessary, it allows to check what
mode was used during startup.

to take that into account.
* Introduced INTEL_TYPE_FAMILY_MASK and INTEL_TYPE_GROUP_MASK to better
differentiate the device type.

output as well.
* Obviously got the register for INTEL_DISPLAY_B_DIGITAL_PORT wrong - it's
not 0x61000 but 0x61140, maybe that can explain the fun we had at BeGeistert :)
* Renamed the analog display registers to better fit the digital ones, ie.
replaced DISPLAY with DISPLAY_A - although this might be not really correct
as it seems that the pipes can be selected arbitrarily.
* Minor cleanup.

Need to clean this up, though. It even sort of worked on tic's IBM X40
on BeGeistert - if you weren't irritated by the fact some parts of the
screen were just black, that is :-)

that at least 8 bit modes seems to work (but overlay only partially)
* Added "hardware_cursor" option to the settings file - when set to "false", you should
have a cursor in the second output now as well.

without having a VESA mode set first (thanks to Stephan for noticing
this).
* intel_set_display_mode() now calls intel_propose_display_mode() to make
sure the mode passed in is valid. Note, B_PROPOSE_DISPLAY_MODE is still
not working correctly (which will cause problems for BWindowScreen and
friends).
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17460 a95241bf-73f2-0310-859d-f6bbb57e9c96
introduced a lock that is used in B_SET_DISPLAY_MODE etc.
* Correctly implemented B_ACQUIRE_ENGINE and B_RELEASE_ENGINE now (ie. they lock
the engine now).
* The lock of the ring buffers is now deleted when the (primary) accelerant is closed.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17453 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Turns out cursor handling is simpler as originally thought, so I could remove its
physical mapping - it's still put into the shared area, though, although that isn't
needed for this chip (but could eventually simplify the handling of other generations
of this chip).

* Waiting for VBLANK now works as expected - you actually have to *set* the bit
to clear it, isn't that obvious? :-)

is no good (or reliable) way to retrieve the physical address of "stolen"
(by the BIOS) graphics memory.
* Implemented allocation of additional graphics memory in case the BIOS was
a bit too cheap. We now guarantee 8 MB of memory available to the graphics
chip - would be nicer to only allocate that on demand, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17433 a95241bf-73f2-0310-859d-f6bbb57e9c96
I am also not sure if it's working correctly.

* B_SCREEN_TO_SCREEN_BLIT is now working as intended, so we can finally move
windows and scroll at decent speed :-)
* Implemented a simple version of B_WAIT_ENGINE_IDLE for now.

the usual order of other registers, so I mixed it up: vertical downscaling
is now working as expected as well.
* The downscaling factor was a tiny bit too low (one pixel from the view).

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.

overlay - this will improve the overlay performance when the engine is
under load (the acceleration engine will use the primary lower priority
ring buffer).

mode), but you have to set the scaling UV registers in order to have correct
overlay.
* In other words, overlay is working now! There are still issues with it, which
can probably be attributed to missing bounds checks (the screen goes black
when you leave full-screen mode in VLC - but not if overlay just stops).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17365 a95241bf-73f2-0310-859d-f6bbb57e9c96
the Intel chip obviously cannot do overlays in B_RGB16 - even though it pretends
to be able to do that.
* B_YCbCr422 seems to work, though, I haven't tested any other spaces for now, and
I somewhat doubt they will work. It's all green, though, and the scaling doesn't
seem to be correct - that we be solvable, though :)
* There aren't any bounds checks (so don't move the window out of the screen), and
also the overlay_view offsets are ignored.
* Scaling and moving is now detected, and there is always as little work done as
possible to reduce the workload on buffer switches (the most common case).

lsb to msb).
* The result is that there is now *something* to see when overlay is turned on. In
fact the whole screen goes dark besides a few pixels on the top - now isn't that
something? :-)
* The overlay is also turned off again correctly - which also revealed a bug in our
app_server: B_CONFIGURE_OVERLAY is not always called with window=NULL/view=NULL
to turn off overlay (might be an incorrect handling of BView::ClearOverlay()).

engine as well.
Some more work on overlay initialization, doesn't do anything yet, though.

to be used.

* 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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17224 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.

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 :)).
