The function was an empty since 2008 at least. Remove it alongside the
unused GLX visuals code.
With this all the GL/GLX dependencies in the driver are gone.

There's a GLX reference in mga_ucode.h - a file which was seemingly
never used since day 1. I'm not going to bother with that, since I've
taken enough of a diversion already ;-)

The other missing symbols is MGAGetClientPointer, that I believe
should be provided by matrox's libHAL.a, that I am afraid if someone
still has a copy of it, it won't work with X Org's loader.

The server expects the driver to take the DRI lock in the wakeup
handler, and release it in the block handler.
The old locking scheme didn't work like this, which caused problems.
We now no longer override wakeup/block handler and just use the ones
provided by the server. This means the DRI lock will be taken
"all the time" and not just when it's needed by the driver.
MGADRISwapContext* are activated again, so the wakeup handler could be
removed.
I didn't notice any DRI performance drop, but I didn't do serious
benchmarking either.

physical bus used for the card. This allows accurate detection of PCI
cards that use a PCI-to-PCI bridge with an AGP chip.
Correctly disable DRI on PCI cards used with pre-3.2 DRM. Previously the
test was performed based on PCI ID (see above for why this is wrong)
and was done *before* the DRM version was known.
Bug #3759: <https://bugs.freedesktop.org/show_bug.cgi?id=3759> Correctly

the wrong bit was tested. Blame the dumb programmer that used

This patch dumps all of the old BIOS processing code from the MGA DDX. The
new code, located in mga_bios.c, is modeled after the code in
matroxfb_misc.c (though no actual code was copied). Basically, the BIOS
is processed in one place, with "device independent" values stored in a
data structure. This data is then used, without extra switch-statments,
throughout the driver.
In addition, this patch adds support for processing the BIOS on PowerPC
systems. On PPC cards, the magic offset values (that give the location
of the PInS data) is not in the BIOS. Instead the driver has to search
the BIOS for the PInS structure signature. The patch does this and
correctly handles byte-ordering (and data alignement) issues.
This code has been tested on an AGP G400 on x86 and a PCI G450 on PowerPC.
NOTE: The file mga_bios.h is also removed. The "documentation" in that file
was moved to the file mga_PInS.txt. This file documents, as much as
possible, the layout of the various PInS datastructure versions. The
information in that file is 100% based on the old mga_bios.h and the
code in matroxfb_misc.c. No additional information from Matrox
documentation is included in that file. This just puts the information
that was already known in one place.

Update MGA DDX to use new features of MGA DRM ersion 3.2 to enable DRI
support on PCI cards. Backwards compatability with older client-side
drivers is enabled with new Device section settings. See mga.man for

MGA driver.
- Use mga_drm.h instead of mga_common.h. Due to this, all the MGA-specific
DRM names were changed to generic versions (i.e., drmMGALock became
drm_lock_t).
- Merge MGADRIMapInit into MGADRIAGPInit and rename the resulting function
MGADRIBootstrapDMA.
- Eliminate several unnecessary drmMap calls. The server has no need to map
MMIO space, primary DMA buffer space, secondary DMA buffer space, WARP
microcode space, or the DRM status page.
- Clarified which portions of the client / server DRI interface are no
longer used.
- Removed some unused fields from MGADRIServerPrivateRec.
- Bump MGA_PATCHLEVEL.
