scope of the object lock in agp_i810.c.  (In this specific case, the scope
of the object lock shouldn't matter, but I don't want to create a bad

This replaces d_mmap() with the d_mmap2() implementation and also
changes the type of offset to vm_ooffset_t.

Purge d_mmap2().

All driver modules will need to be rebuilt since D_VERSION is also

66ab1230f1 Fix a handful of issues with via agp support.
* Read the pci capability register to identify AGP 3 support
  * Add missing smaller aperture sizes for AGP3 chips.
  * Fix the aperture size calculation on AGP2 chips.
    All sizes between 32M and 256M reported as 256M.
  * Add \n to error string.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

ce6d690203 Calculate the number of pages the GATT spans when reading from each page
to flush the TLB instead of hardcoding a size of 33 pages.  Apertures of
32MB and 64MB only use a 16 page GATT and an aperture of 128MB only uses
a 32 page GATT, so without this the code could walk off the end of the
pointer and cause a page fault if the next page was unmapped.  Also, for
aperture sizes > 128MB, not all of the pages would be read.  The Linux
driver has the same bug.

f82a1d4987 Split agp_generic_detach() up into two routines: agp_free_cdev() destroys
/dev/agpgart and agp_free_res() frees resources like the BAR for the
aperture.  Splitting this up lets chipset-specific detach routines
manipulate the aperture during their detach routines without panicing.

d450e052dc Add support for G965/Q965/GM965/GME965/GME945 AGP.
This adds a function to agp.c to set the aperture resource ID if it's
not the usual AGP_APBASE.  Previously, agp.c had been assuming
AGP_APBASE, which resulted in incorrect agp_info, and contortions by
agp_i810.c to work around it.

This also adds functions to agp.c for default AGP_GET_APERTURE() and
AGP_SET_APERTURE(), which return the aperture resource size and disallow
aperture size changes.  Moving to these for our AGP drivers will likely
result in stability improvements.  This should fix 855-class aperture
size detection.

Additionally, refuse to attach agp_i810 when some RAM is above 4GB and
the GART can't reference memory that high.  This should be very rare.
The correct solution would be bus_dma conversion for agp, which is
beyond the scope of this change.  Other AGP drivers could likely use
this change as well.

G33/Q35/Q33 AGP support is also included, but disconnected by default
due to lack of testing.

afadbf66cb - Clean up Aperture Access Global Enable (APEN) bit access.
- Rename confusing AGP_INTEL_I845_MCHCFG to AGP_INTEL_I845_AGPM.
- Move E7205 and E7505 from i8x5 to i8x0 family.  It probably worked
because the actual offset is the same.

In fact, all three families have the bit at the exact same place.  Only
differences are name and width of the registers, i.e., NBXCFG (0x50, dword),
RDCR (0x51, byte), AGPM (0x51, byte), MCHCFG (0x50, word) depending on
the family of the chipsets.

30e14d656c Add support for 945G/GM AGP chipsets.
The key problem was that the aperture size detection using the MSAC bit
doesn't work -- the bit appears to be set even when it shouldn't be.  Linux
takes a different approach, testing for a bit of the GMADR (PCIR_BAR(2)) being
set.  However, as I don't think that's a safe way to test aperture size, we
just allocate the resource and check its size.  This also pointed out that
agp_generic_attach hadn't been allocating our aperture resource, which may
have caused problems in some cases.

Also corrected is a minor copy-and-pasteo in an error case.
