[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with

A rewrite of the i810 bits of the agp(4) driver. New driver supports
operations required by GEMified i915.ko. It also attaches to SandyBridge
and IvyBridge CPU northbridges now.

Add a driver for the Apple Uninorth AGP host bridge found in all PowerPC
Macintoshes with an AGP bus.

MFtbemd:

Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the
source code location of the machine, the latter the binary output. In
general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless
we're tesitng for a specific target. The isn't even moot for
i386/amd64 where there's momemntum towards a MACHINE_CPUARCH == x86,
although a specific cleanup for that likely would be needed...

Fix a few problems related to building modules in /sys/modules (not
checked whether this applies to builds in /sys/*/compile/* as well):

- Create empty opt_*.h files were missing
- Hook up svr4 to the build. It compiles fine here, so no reason to
disconnect it in the Makefile. were missing
- Hook up svr4 to the build. It compiles fine here, so no reason to

- 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.
- Align "optional agp" in conf/files.* for consistency while I am here.

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.

Add a new AGP driver for ATI IGP chipsets. The driver is based on reading of

it working.

The tinderbox seems to have a different set of compiler options
enabled than my box, so the agp module gets different warnings than I
got when I built. WERROR= to compensate.

opt_agp.h is not required anymore.

agp_amd64.c is not needed on pc98.

AGP GART driver for NVIDIA nForce/nForce2 chipsets.

Split the arch-specific AGP files into the appropriate files.* and do the same
for the agp module, and add agp to the list of modules to compile for alpha.
Add an alpha_mb() to agp_flush_cache for alpha -- it's not correct but may
improve the situation, and it's what linux and NetBSD do.

Remove opt_pci.h from SRCS.

Export symbols that constitute APIs defined by these
modules.

Note that in the case of 'mii' the API is not clearly
defined, and the symbols exported represent a subset
defined by current usage.

Use a consistent style and one much closer to the rest of /usr/src

Next phase in the PCI subsystem cleanup.

- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.

Remove the NCPU, NAPIC, NBUS, NINTR config options. Make NAPIC,
NBUS, NINTR dynamic and set NCPU to a maximum of 16 under SMP.
