a8de37b024 This isn't functionally identical. In some cases a hint to disable
unit 0 would in fact disable all units.

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.

This all seems to get the CLE266 EPIA-M board agp working properly, now
back to work on drm.

129dec4245 - Add few VIA bridges to agp_via.c and connect it to amd64 build
as they support Intel Core/Core 2 and VIA Nano processors.

dbac8ff400 Move the agp(4) driver from sys/pci to sys/dev/agp. __FreeBSD_version was
bumped to 800004 to note the change though userland apps should not be
affected since they use <sys/agpio.h> rather than the headers in
sys/dev/agp.

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.

c626f1fe9a Change the various AGP drivers that attach to the Host-PCI bridge device to
attach to the hostb driver instead.  This means that agp can now be loaded
at runtime (in theory at least).  Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).

124cfec04a [1] Remove the generic bridge support from those drivers that had it. The
generic bridge support was biting us more than it helped, whenever a new chipset
came out from a vendor and misprogramming it caused strange hangs or corruption.
[2] Add a large number of PCI IDs based on what the linux drivers support.
Note that the new PCI IDs haven't been tested, they're just *likely* to work.
In particular the VIA AGP 8x chipsets are concerning, due to lack of testing,
possible issues (kern/69953), and not having a nice "does this bridge say it
would do 8x" function.  However, this shouldn't make the situation worse, since
these chips would have probed in the past anyway.

b6e05739c5 Minimal fix to prevent crashes when an AGP v2 card is used with the new v3 VIA
chipsets, based on Linux's via-agp.c.  On boot, the system selects which AGP
version to use based on the inserted card.  If v2 was chosen, the chipset
needs to be programmed with the v2 registers still.  Also included in kern/69953
are changes to make the programming of the v3 registers match linux, but that
will be left out until the need to do so is confirmed (want specs or a tester).

92cb9c9b67 Different VIA host bridges use different offsets to their AGP config
registers, so add a register offset array to the softc.  We key off the
device ID to determine which set of register offsets.  Currently the 8385
host bridge used on amd64 is the only bridge to use the AGP3_VIA_*
register offsets and all other bridges use the AGP_VIA_* offsets.  It is
currently unclear if the AGP3_VIA_* offsets are for VIA bridges that
implement AGP 3.0 bridges or just for amd64 bridges.

2395531439 Introduce a global lock for the vm subsystem (vm_mtx).
vm_mtx does not recurse and is required for most low level
vm operations.

faults can not be taken without holding Giant.

Memory subsystems can now call the base page allocators safely.

Almost all atomic ops were removed as they are covered under the
vm mutex.

Alpha and ia64 now need to catch up to i386's trap handlers.

FFS and NFS have been tested, other filesystems will need minor
changes (grabbing the vm lock when twiddling page properties).

597472167a A driver for programming the AGP hardware. This is only very lightly
tested on Intel BX chipsets only. The other agp minidrivers are totally
untested.

The programming api is a subset of the Linux api and is only intended to
be enough for the X server to use. There is also an in-kernel api for the
use of other kernel modules such as the 3D DRI.
