this is mostly from freebsd (though it also exists in other versions
of the drm code) svn commits:
--
SVN rev 196470 on 2009-08-23 14:55:57Z by rnoland
Add kernel support for Radeon R6/7xx 3D.
You will still need Mesa from git and possibly an updated DDX driver,
but this is working fairly well now.

SVN rev 196142 on 2009-08-12 12:57:02Z by rnoland
Add support for radeon RS880 IGP chips to drm.
--
SVN rev 195501 on 2009-07-09 16:39:28Z by rnoland
Add support for Radeon HD 4770 (RV740) chips.
--
SVN rev 196471 on 2009-08-23 15:02:58Z by rnoland
Add GET_PARAM support for Z pipes.
This is needed for occulsion queries on rv530 chips.

SVN rev 198695 on 2009-10-30 18:07:22Z by rnoland
A bit of cleanup work on radeon_freelist_get()
* Fix the main loop to search all buffers before sleeping.
* Remove dead code

SVN rev 197606 on 2009-09-28 22:41:28Z by rnoland
Fix offset handling
--
SVN rev 197605 on 2009-09-28 22:40:29Z by rnoland
radeon_family is an enum, so ordering can be important.
sync up with what amd is shipping.
--
SVN rev 197603 on 2009-09-28 22:37:07Z by rnoland
R600 doesn't support IRQs yet, so don't try to use them.

special thanks to robert noland @ freebsd for making this an
easy port!
some bus space somewhere. otherwise, just use normal accesses since
it is normal memory.
this fixes radeondrm on x86 since bus_space_tag_t became a pointer.
add the "GEM" and "TTM" mapping types to sysctl support (though right
now we will never have them in our list of maps.)
Selected changes between 20090730 and 20100121:
* A "post-order callback" was added to AcpiWalkNamespace().
* The ACPI_INTEGER type was removed and replaced with UINT64. Support for
this type remains (for the time being) for compatibility reasons.
* AcpiGetDevices() was optimized to not run extra _STA methods.
* Fixed possible mutex acquisition errors when running _REG methods.
* iASL was fixed not to fault when the maximum number of errors is
reached.
* Various miscellaneous fixes and improvements, including, for example,
improved object repair capabilities, memory leak fixes, better type
conversions, module-level code execution, etc.
- we have to DRM_LOCK()/DRM_UNLOCK(), thus s/rad_dev/dev/ in a variable name
- only call into radeon_cp_{stop,resume}() if the device is active
with this my nforce4 dual core amd system is able to suspend/resume with both
X and drm active.

XXX: The internal memory tracking of ACPICA, available when
ACPI_DBG_TRACK_ALLOCATIONS is defined, has been removed
from ACPI_DEBUG.
This is due to the instability of the ABI of ACPICA.
If the memory tracking is enabled, ACPICA will insert a header
to each memory allocation. As a consequence, when ACPI specific
code is loaded as a kernel module and the running kernel has
been compiled with ACPI_DEBUG, the result is an instant panic.
This happens because of unaligned memory access when the code
tries to use ACPI_FREE for a buffer obtained via ACPI_ALLOCATE,
AcpiEvaluateObject(), and related calls.
If the involved memory statistics are required, a separate constant
ACPI_DEBUG_ALLOC is available in options(4) for ACPI_DEBUG kernels.
* * *
Discussed with, and ok'ed by, jmcneill@ and pooka@.
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.
viadrm0 at vga1: VIA P4M900 / VN896
viadrm0: AGP at 0xf0000000 128MB
viadrm0: Initialized via 2.11.1 20070202
xf86-video-openchrome seems happy with it, although 3d acceleration isn't
supported on the P4M900 so I can't test that part.
("(boundary & (boundary - 1)) == 0") triggers with i915drm in recent -5 kernel
Read the comment in the code for a detailed explanation. This should be fixed
properly in the i386 bus code, but it is too intrusive to do for -5.
XXX: pullup for 5.x
all the files attached to dev->files. we check for one per "open_count"
that is above 1. could perhaps assert() that we are empty afterwards.
this fixes restarting X + drm after actually using drm.
- call drm_rmmap() in radeon_do_cleanup_cp on the two maps created
- in several vblank functions, check to make sure we have mappings
enabled before doing something that might blow up. fixes PR#41715.
with our changes and the work recently done by Arto Huusko
<arto.huusko@pp2.inet.fi> and FUKAUMI Naoki <fun@naobsd.org>.
it includes all the changes arto provided from both mesa-drm and
the r6xx-r7xx-support branch. it does not yet include code to
handle the (deleted) drm_pciids.h file, but i'll probably just
check in a generated one for now.
i have not yet merged the changes from outside this dir.
from arto's messages to tech-x11:
The important change that was needed is that drm_scatter.c was
fixed to return pointer to all allocated pages, not just the
beginning of the allocated segments.
Other changes:
- drm_scatter maps COHERENT memory
- drm_drawable: drawable handle allocation is done
inside lock
- drm_memory: when mapping "agp" memory, store offset
of mapped area, so that new requests to same offset
return the same area instead of trying to remap
and fail
- drm_vm: use bus_space_mmap for frame buffer and registers
- r600_cp.c: ioremapfree allocated gart range
- radeon_cp.c: use mtsleep
- some memset calls I had added had their args swapped,
and no memory was cleared
