+        bool "Enable modesetting on radeon by default"
+        depends on DRM_RADEON
+        select DRM_TTM
+        help
+          Choose this option if you want kernel modesetting enabled by default,
+          and you have a new enough userspace to support this. Running old
+          userspaces with this enabled will cause pain.
+          When kernel modesetting is enabled the IOCTL of radeon/drm
+          driver are considered as invalid and an error message is printed
+          in the log and they return failure.
+          KMS enabled userspace will use new API to talk with the radeon/drm
+          driver. The new API provide functions to create/destroy/share/mmap
+          buffer object which are then managed by the kernel memory manager
+          (here TTM). In order to submit command to the GPU the userspace
+          provide a buffer holding the command stream, along this buffer
+          userspace have to provide a list of buffer object used by the
+          command stream. The kernel radeon driver will then place buffer
+          in GPU accessible memory and will update command stream to reflect
+          the position of the different buffers.
+          The kernel will also perform security check on command stream
+          provided by the user, we want to catch and forbid any illegal use
+          of the GPU such as DMA into random system memory or into memory
+          not owned by the process supplying the command stream. This part
+          of the code is still incomplete and this why we propose that patch
+          as a staging driver addition, future security might forbid current
+          experimental userspace to run.
+          This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
+          (radeon up to X1950). Works is underway to provide support for R6XX,
+          R7XX and newer hardware (radeon from HD2XXX to HD4XXX).

+The following IGP table is introduced from RS780, which is supposed to be put by SBIOS in FB before IGP VBIOS starts VPOST;
+Then VBIOS will copy the whole structure to its image so all GPU SW components can access this data structure to get whatever they need.
+The enough reservation should allow us to never change table revisions. Whenever needed, a GPU SW component can use reserved portion for new data entries.
+SW components can access the IGP system infor structure in the same way as before

+ * @num_pages: Actual number of pages.
+ * @addr_space_offset: Address space offset.

+ * zero, the object is put on the delayed delete list.
+ * @list_kref: List reference count of this buffer object. This member is
+ * used to avoid destruction while the buffer object is still on a list.
+ * Lru lists may keep one refcount, the delayed delete list, and kref != 0
+ * keeps one refcount. When this refcount reaches zero,
+ * the object is destroyed.
+ * @event_queue: Queue for processes waiting on buffer object status change.
+ * @lock: spinlock protecting mostly synchronization members.
+ * @proposed_placement: Proposed placement for the buffer. Changed only by the
+ * creator prior to validation as opposed to bo->mem.proposed_flags which is
+ * changed by the implementation prior to a buffer move if it wants to outsmart
+ * the buffer creator / user. This latter happens, for example, at eviction.
+ * @mem: structure describing current placement.
+ * @persistant_swap_storage: Usually the swap storage is deleted for buffers
+ * pinned in physical memory. If this behaviour is not desired, this member
+ * holds a pointer to a persistant shmem object.
+ * @ttm: TTM structure holding system pages.
+ * @evicted: Whether the object was evicted without user-space knowing.
+ * @cpu_writes: For synchronization. Number of cpu writers.
+ * @lru: List head for the lru list.
+ * @ddestroy: List head for the delayed destroy list.
+ * @swap: List head for swap LRU list.
+ * @val_seq: Sequence of the validation holding the @reserved lock.
+ * Used to avoid starvation when many processes compete to validate the
+ * buffer. This member is protected by the bo_device::lru_lock.
+ * @seq_valid: The value of @val_seq is valid. This value is protected by
+ * the bo_device::lru_lock.
+ * @reserved: Deadlock-free lock used for synchronization state transitions.
+ * @sync_obj_arg: Opaque argument to synchronization object function.
+ * @sync_obj: Pointer to a synchronization object.
+ * @priv_flags: Flags describing buffer object internal state.
+ * @vm_rb: Rb node for the vm rb tree.
+ * @vm_node: Address space manager node.
+ * @offset: The current GPU offset, which can have different meanings
+ * depending on the memory type. For SYSTEM type memory, it should be 0.
+ * @cur_placement: Hint of current placement.
+ *
+ * Base class for TTM buffer object, that deals with data placement and CPU
+ * mappings. GPU mappings are really up to the driver, but for simpler GPUs
+ * the driver can usually use the placement offset @offset directly as the
+ * GPU virtual address. For drivers implementing multiple
+ * GPU memory manager contexts, the driver should manage the address space
+ * in these contexts separately and use these objects to get the correct
+ * placement and caching for these GPU maps. This makes it possible to use
+ * these objects for even quite elaborate memory management schemes.
+ * The destroy member, the API visibility of this object makes it possible
+ * to derive driver specific types.

+ *
+ * Deadlocks may occur when two processes try to reserve multiple buffers in
+ * different order, either by will or as a result of a buffer being evicted
+ * to make room for a buffer already reserved. (Buffers are reserved before
+ * they are evicted). The following algorithm prevents such deadlocks from
+ * occuring:
+ * 1) Buffers are reserved with the lru spinlock held. Upon successful
+ * reservation they are removed from the lru list. This stops a reserved buffer
+ * from being evicted. However the lru spinlock is released between the time
+ * a buffer is selected for eviction and the time it is reserved.
+ * Therefore a check is made when a buffer is reserved for eviction, that it
+ * is still the first buffer in the lru list, before it is removed from the
+ * list. @check_lru == 1 forces this check. If it fails, the function returns
+ * -EINVAL, and the caller should then choose a new buffer to evict and repeat
+ * the procedure.
+ * 2) Processes attempting to reserve multiple buffers other than for eviction,
+ * (typically execbuf), should first obtain a unique 32-bit
+ * validation sequence number,
+ * and call this function with @use_sequence == 1 and @sequence == the unique
+ * sequence number. If upon call of this function, the buffer object is already
+ * reserved, the validation sequence is checked against the validation
+ * sequence of the process currently reserving the buffer,
+ * and if the current validation sequence is greater than that of the process
+ * holding the reservation, the function returns -EAGAIN. Otherwise it sleeps
+ * waiting for the buffer to become unreserved, after which it retries
+ * reserving.
+ * The caller should, when receiving an -EAGAIN error
+ * release all its buffer reservations, wait for @bo to become unreserved, and
+ * then rerun the validation with the same validation sequence. This procedure
+ * will always guarantee that the process with the lowest validation sequence
+ * will eventually succeed, preventing both deadlocks and starvation.
+ *
+ * Returns:
+ * -EAGAIN: The reservation may cause a deadlock.
+ * Release all buffer reservations, wait for @bo to become unreserved and
