Dave Airlie 6795c985a6 Add support for PCI MGA cards to MGA DRM.
This patch adds serveral new ioctls and a new query to get_param query to
support PCI MGA cards.

Two ioctls were added to implement interrupt based waiting.  With this change,
the client-side driver no longer needs to map the primary DMA region or the
MMIO region.  Previously, end-of-frame waiting was done by busy waiting in the
client-side driver until one of the MMIO registers (the current DMA pointer)
matched a pointer to the end of primary DMA space.  By using interrupts, the
busy waiting and the extra mappings are removed.

A third ioctl was added to bootstrap DMA.  This ioctl, which is used by the
X-server, moves a *LOT* of code from the X-server into the kernel.  This allows
the kernel to do whatever needs to be done to setup DMA buffers.  The entire
process and the locations of the buffers are hidden from user-mode.

Additionally, a get_param query was added to differentiate between G4x0 cards
and G550 cards.  A gap was left in the numbering sequence so that, if needed,
G450 cards could be distinguished from G400 cards.  According to Ville
Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering
differently.  This seems the most compatible way to let the client-side driver
know which card it's own.  Doing this very small change now eliminates the
need to bump the DRM minor version twice.

(airlied - this may not work at this point, I think the follow on buffer
 cleanup patches will be needed)

Kernel-level support for the Direct Rendering Infrastructure (DRI)
introduced in XFree86 4.0. If you say Y here, you need to select
the module that's right for your graphics card from the list below.
These modules provide support for synchronization, security, and
DMA transfers. Please see <http://dri.sourceforge.net/> for more
details. You should also select and configure AGP
(/dev/agpgart) support.
config DRM_TDFX
tristate "3dfx Banshee/Voodoo3+"
depends on DRM && PCI
help
Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
graphics card. If M is selected, the module will be called tdfx.

help
This is the old gamma driver, please tell me if it might actually
work.
config DRM_R128
tristate "ATI Rage 128"
depends on DRM && PCI
help
Choose this option if you have an ATI Rage 128 graphics card. If M
is selected, the module will be called r128. AGP support for
this card is strongly suggested (unless you have a PCI version).
config DRM_RADEON
tristate "ATI Radeon"
depends on DRM && PCI
help
Choose this option if you have an ATI Radeon graphics card. There
are both PCI and AGP versions. You don't need to choose this to
run the Radeon in plain VGA mode. There is a product page at
<http://www.ati.com/na/pages/products/pc/radeon32/index.html>.
If M is selected, the module will be called radeon.
config DRM_I810
tristate "Intel I810"
depends on DRM && AGP && AGP_INTEL
help
Choose this option if you have an Intel I810 graphics card. If M is
selected, the module will be called i810. AGP support is required
for this driver to work.

Choose this option if you have a system that has Intel 830M, 845G,
852GM, 855GM or 865G integrated graphics. If M is selected, the
module will be called i830. AGP support is required for this driver
to work. This driver will eventually be replaced by the i915 one.

Choose this option if you have a system that has Intel 830M, 845G,
852GM, 855GM 865G or 915G integrated graphics. If M is selected, the
module will be called i915. AGP support is required for this driver
to work. This driver will eventually replace the I830 driver, when
later release of X start to use the new DDX and DRI.
