15e3b9f750 Avoid repeated acquisition and release of the vm object lock inside of
two loops in agp_generic_bind_memory().  As an intended side-effect, all
of the calls to vm_page_wakeup() are now performed with the containing
vm object lock held.

1095443edb Fix aperture size detection on some ALi chipsets by only using the lowest 4 bits
to check aperture size, avoiding hangs.  Maintain the rest of the bits when
setting/unsetting ATTBASE.  This essentially matches Linux's AGP driver as well.

a5739e0b31 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).

f3429f1d78 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.

106fdfcb2b Push down the responsibility for zeroing a physical page from the
caller to vm_page_grab().  Although this gives VM_ALLOC_ZERO a
different meaning for vm_page_grab() than for vm_page_alloc(), I feel
such change is necessary to accomplish other goals.  Specifically, I
want to make the PG_ZERO flag immutable between the time it is
allocated by vm_page_alloc() and freed by vm_page_free() or
vm_page_free_zero() to avoid locking overheads.  Once we gave up on
the ability to automatically recognize a zeroed page upon entry to
vm_page_free(), the ability to mutate the PG_ZERO flag became useless.
Instead, I would like to say that "Once a page becomes valid, its
PG_ZERO flag must be ignored."

fbb6062925 Fix support for 256 MB aperture sizes on chipsets such as the 845 and
865.  The APSIZE register has a variable-sized field of enabled bits.
To figure out how many bits a specific host bridge supports, write the
maximum width and see how many bits are set in the hardware.  We then
use this mask for setting and getting the aperture size.  Prior to this,
the agp(4) driver would treat an aperture size of 256 MB as 128 MB and
would not allocate enough physical memory for the GART as a result.

783ae539c3 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.
