Add interface entry cleaning a memory type without touching NO_EVICT buffers.

Change the restriction that non-creators can't change the buffer flags to
non-creators can't change EVICT and NO_MOVE flags.

Remove need for lock for now.
May create races when we clean memory areas or on takedown.
Needs to be fixed.
Really do a validate on buffer creation in order to avoid problems with
fixed memory buffers.

We now always create a drm_ref_object for user objects and this is then the only
things that holds a reference to the user object. This way unreference on will
destroy the user object when the last drm_ref_object goes way.
|
|
The buffer object type is still tracked internally, but it is no longer
part of the user space visible ioctl interface. If the bo create ioctl
specifies a non-NULL buffer address we assume drm_bo_type_user,
otherwise drm_bo_type_dc. Kernel side allocations call
drm_buffer_object_create() directly and can still specify drm_bo_type_kernel.
Not 100% this makes sense either, but with this patch, the buffer type
is no longer exported and we can clean up the internals later on.

This is some code for nouveau that Ben Skeggs worked on, and also
fixes the naming (having class in a system header file == C++ keyword == bad plan)

Modify the TTM backend bind arguments.
Export a number of functions needed for driver-specific super-ioctls.
Add a function to map buffer objects from the kernel, regardless of where they're
currently placed.
A number of error fixes.

Also, be a little safer with setting the pinned flag within the struct lock.
I'm not 100% sure if this is required, but it seems like it might be.

This should let us allocate buffers without holding the hardware lock.
While here, add DRM_DEBUG info for the drm_bo ioctls, so you can see something
more specific than just the cmd value per ioctl.

This cleans up the create/validate interfaces for this very uncommon path, and
makes pinned object creation much easier to use for the X Server.

The data is now in kernel space, copied in/out as appropriate according to the
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 DRM
is lost.

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 everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

|
This might break something, stdint.h inclusion in drm.h maybe required
but I'm not sure yet what platforms have it what ones don't.

Buffer object dereference cleanup.
Add a struct drm_device member to fence objects:
This can simplify code, particularly in drivers.

Remove the implicit fence-class mechanism.

retain the op operation for validate/fence operations
|

This just cleans up the xf86drm.c to what I want and drm.h,
I need to fix up the kernel internals to suit these changes now.
I've moved to using struct instead of typedefs for the bo and it doesn't look
that bad so I'll do the same thing for mm and fence..
