drm: reorganise drm tree to be more future proof.

2008-07-14T00:45:01+00:00

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.

This restructures the drm along the lines of other kernel components.

It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.

drm: remove remnants of DRM_COPY_FROM/TO_USER_IOCTL

2007-11-06T00:11:12+00:00

This is a bug in the savage driver since I introduced these changes.

Use helpers to obtain task pid in printks

2007-10-19T18:53:43+00:00

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.

2007-10-15T00:38:20+00:00

The data is now in kernel space, copied in/out as appropriate according to t
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures.  This also means that XFree86 4.2.0 support for i810 DR
is lost.

drm: Replace filp in ioctl arguments with drm_file *file_priv.

2007-10-15T00:38:20+00:00

As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everyth
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct
went the other direction.

drm: Remove DRM_ERR OS macro.

2007-10-15T00:38:19+00:00

This was used to make all ioctl handlers return -errno on linux and errno on
*BSD.  Instead, just return -errno in shared code, and flip sign on return f
shared code to *BSD code.

drm: cleanup use of Linux list handling macros

2007-07-11T01:58:02+00:00

This makes the drms use of the list handling macros a lot cleaner
and more along the lines of how they should be used and uses them
in some more places.
