There's two choices when fb is or isn't loaded as we treat ourselves as a
PCI driver in the latter case.
If we are a PCI driver, then register the suspend/resume functions
directly. If not, then we register as a sysdev and pick up the
suspend/resume actions and pump them down into a generic *power
function.
It'll be nice when this little mess is sorted out with regard to being a
real PCI driver ;-/
that a device absolutely is, absolutely is not, or may or may not be
AGP. Modify the i915 DRM to use this to force all i9x5 devices to be
"AGP" (even the PCI-e devices).

platform-specific drm_device_is_agp function. Added implementation of
this function the the Linux-specific portion of the MGA driver to
detect PCI G450 cards. Added code to the Linux-specific portion of the
generic DRM layer to not initialize AGP infrastructure if the card is
not AGP (this matches what already existed in BSD).
Bumped the driver date and the driver patch-level for MGA.
This mostly fixes bugzilla #3248. The BSD side still needs an
implementation of mga_driver_device_is_agp.
with IOMMUs and such. There is one usage of the forbidden vtophys()
left in drm_scatter.c which will be fixed up soon. This required a KPI
change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
keeps track of os-specific bits, rather than just passing around the
vaddr/busaddr/size.

FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff
doesn't need to be in shared code.
- Fix mach64 build by using __DECONST to work around passing a const
pointer to useracc, which is unfortunately not marked const.
- Get rid of a lot of maplist code by not having dev->maplist be a pointer,
and by sticking the link entries directly in drm_local_map_t rather
than having a separate structure for the linked list.
- Factor out map uninit and removal into its own routine, rather than
duplicating in both drm_takedown() and drm_rmmap().
- Hook up more driver functions, and correct FreeBSD-specific bits of
radeon_cp.c, making radeon work.
- Baby steps towards using bus_space as we should.
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP
memory but uses video memory.

hotplug event plus the addition of one requesting RESET. Put your
scripts in /etc/hotplug.d/drm to run. kernel class_simple generates the
ADD/REMOVE events. No cards currently request RESET, the flag is there
to stop you from resetting your boot display.
allows the mesa drivers to use a single definition of the DRM
sarea/IOCTLS located in the drm driver directory. Adjustments were made
to the 2D drivers to not include these changes. Changes to the mesa
copy of DRM were copied to the DRI copy. XFree86 bug: Reported by:

a busid that doesn't correspond to the device the DRM is attached to.
This is a breaking of backwards-compatibility only for the
multiple-DRI-head case with X Servers that don't use interface 1.1.
- Move irq_busid to drm_irq.h and make it only return the IRQ for the
current device. Retains compatibility with previous X Servers, cleans
up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be
changed if necessary.
- Bump interface version to 1.2. This version when set signifies that the
control ioctl should ignore the irq number passed in and enable the
interrupt handler for the attached device. Otherwise it errors out when
the passed-in irq is not equal to the device's.
- Store the highest version the interface has been set to in the device.
- Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves
irq_uninstall being done without the lock in some cases, but it was
racey anyways.
the 2D driver initializes MC_FB_LOCATION and related registers sanely
the DRM deduces the layout from these registers
clients use the new SETPARAM ioctl to tell the DRM where they think the
framebuffer is located in the card's address space
the DRM uses all this information to check client state and fix it up if
necessary
This is a prerequisite for things like direct rendering with IGP chips and
video capturing.
server or client to notify the DRM that it expects a certain version of
the device dependent or device independent interface. If the major
doesn't match or minor is too large, EINVAL is returned. A major of -1
means that the requestor doesn't care about that portion of the
interface. The ioctl returns the actual versions in the same struct.
- Introduce DRM DI interface version 1.1. If the server requests version
1.1, then the DRM sets the unique itself according to the busid of the
device it probed, which may then be accessed as normal using getunique.
- Request version 1.1 in libdrm's drmOpenByBusID, allowing the X Server to
request based on a BusID. Introduce a wrapper for DRM_IOCTL_SET_VERSION
and bump libdrm minor version.
- Pass the busid in DRIScreenInit if libdrm can handle both a busid and
name. This allows drmOpenByBusID to be used to find the DRM instead of
just the driver name, which allows us in the future to tie a DRM more
strongly to the device it probed to. Introduce a function
DRICreatePCIBusID which creates a busid in the form pci:oooo:bb:dd.f
similar to linux's pci_name() function. This matches the format used by
the DRM in version 1.1. libdrm knows how to match both this format and
the old PCI🅱️d:f format.
- Use the new DRICreatePCIBusID function in the *_dri.c to request the new,
more exact busid format.
from __HAVE_DMA. This will be useful for adding vblank sync support to
sis and tdfx. Rename dma_service to irq_handler, which is more
accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
the right number of underscores. This may have been a problem in the
case that the server died without doing its DRM_IOCTL_CONTROL to
uninit.
just a single instance. Moved the PCI ID lists from <card>_drv.c in BSD
to <card>.h. The PCI ID lists include a driver private field, which may
be used by drivers for chip family or other information. Based on work
by jonsmirl.
- Make tdfx_drv.c and tdfx.h match other drivers.
- Fixed up linking of sis shared files.
Tested with Radeon and SiS on Linux and FreeBSD, including a Linux setup
with
2 SiS cards in a machine, but only one head being used (with DRI)
respectively. Splited the work out of the ioctls and renamed (with the
_ioctl prefix). Added some more documentation. Did the same for
drm_sgpsupport.h.
- Reset 'bound' flag for an agp entry after undbind succeeded in
drm_agpsupport.h (Egbert Eich).
- Ignore hw_lock for drm device if lock was set by a different instance (ie
Xserver) to prevent second server from spinning in driver release
function (currently only relevant for i8xx drm drivers) (David Dawes).
- Use the agpgart "key" for the unique handle for bindings rather than the

- Major rework of the 2D i830/i845G support, including:
- Improve VESA mode selection, and fix refresh rate selection.
- Don't duplicate functions provided in the vbe modules.
- Don't duplicate functions provided in the vgahw module.
- Rewrite memory allocation.
- Rewrite initialisation and save/restore state handling.
- Decouple the i810 support from i830 and later.
- Remove various unnecessary hacks and workarounds.
- Fix an 845G problem with the ring buffer not in pre-allocated memory.
- Fix screen blanking.
- Fix some HW cursor glitches, and turn HW cursor off at VT switch and
exit.
- Don't attempt to use the i830's function 1 entity.
- Fix problems with option handling. (David Dawes).
- Add mode VBE-aware mode handling functions to the vbe module (David
Dawes).
agp chipsets to drm_agpsupport.h, redid the card detection common code
to use a structure (avoids endian porting issues), changed the tdfx
driver to use the kernel pci id '#defines'
- Fix old-style DMA for gamma driver (please test).
- Pull out IRQ handling into drm_dma.h (please test on i810, gamma).
- Lots of general cleanups, remove compiler warnings etc.
against 2.2.18pre21
As usual, since all 2.4.0-test* kernels set LINUX_VERSION_CODE to the same
value, if you are running a 2.4.0-test kernel, you MUST be running
2.4.0-test11-pre4 or later (although anything after 2.4.0-test11-pre1
should work fine -- I tested with pre4/pre5). I expect 2.2.x support to
continue to work for all recent kernels, but I tested with 2.2.18pre21
-- we use the old intermodule symbol communication for 2.2.x kernels,
so they should all continue to work.
several fixes including: (Jeff) Really disable multitexture (Broken
since Mesa 3.4 integration.)
(Jeff) Various changes in mga_state.c in the kernel module, which includes
a fix to the bug where the first OGL application hangs the machine
w/out rendering anything. This also includes defines for the warp
registers so they are easily human readable.
(Rik and Jeff) Fixed all the schedule loops in the kernel to look like they
are supposed too.
(Jeff) Configurable agp modes: Add the option "AGPMode2x" or "AGPMode4x" to
your XF86Config file.
(Rik) Various cleanups to the mga kernel driver to make it easier to read
and debug.
(Rik) Removed alot of DRM_DEBUG statements from the kernel driver.
