+      The Linux DRM layer contains code intended to support the needs
+      of complex graphics devices, usually containing programmable
+      pipelines well suited to 3D graphics acceleration.  Graphics
+      drivers in the kernel can make use of DRM functions to make
+      tasks like memory management, interrupt handling and DMA easier,
+      and provide a uniform interface to applications.

+      This chapter documents DRM internals relevant to driver authors
+      and developers working to add support for the latest features to
+      existing drivers.
+    </para>
+    <para>
+      First, we'll go over some typical driver initialization
+      requirements, like setting up command buffers, creating an
+      initial output configuration, and initializing core services.
+      Subsequent sections will cover core internals in more detail,
+      providing implementation notes and examples.

+    <para>
+      The DRM layer provides several services to graphics drivers,
+      many of them driven by the application interfaces it provides
+      through libdrm, the library that wraps most of the DRM ioctls.
+      These include vblank event handling, memory
+      management, output management, framebuffer management, command
+      submission &amp; fencing, suspend/resume support, and DMA
+      services.

+    <para>
+      The core of every DRM driver is struct drm_device.  Drivers
+      will typically statically initialize a drm_device structure,
+      then pass it to drm_init() at load time.

+      In the example above, taken from the i915 DRM driver, the driver
+      sets several flags indicating what core features it supports.
+      We'll go over the individual callbacks in later sections.  Since
+      flags indicate which features your driver supports to the DRM
+      core, you need to set most of them prior to calling drm_init().  Some,
+      like DRIVER_MODESET can be set later based on user supplied parameters,
+      but that's the exception rather than the rule.

+      In this specific case, the driver requires AGP and supports

+      in this case.  It also supports the kernel mode setting APIs, though
+      unlike in the actual i915 driver source, this example unconditionally
+      exports KMS capability.

+  <!-- Internals: driver load -->
+  <sect1>
+    <title>Driver load</title>
+    <para>
+      In the previous section, we saw what a typical drm_driver
+      structure might look like.  One of the more important fields in
+      the structure is the hook for the load function.
+    </para>
+    <programlisting>
+      static struct drm_driver driver = {
+        ...
+        .load = i915_driver_load,
+        ...
+      };
+    </programlisting>
+    <para>
+      The load function has many responsibilities: allocating a driver
+      private structure, specifying supported performance counters,
+      configuring the device (e.g. mapping registers &amp; command
+      buffers), initializing the memory manager, and setting up the
+      initial output configuration.
+    </para>
+    <para>
+      Note that the tasks performed at driver load time must not
+      conflict with DRM client requirements.  For instance, if user
+      level mode setting drivers are in use, it would be problematic
+      to perform output discovery &amp; configuration at load time.
+      Likewise, if pre-memory management aware user level drivers are
+      in use, memory management and command buffer setup may need to
+      be omitted.  These requirements are driver specific, and care
+      needs to be taken to keep both old and new applications and
+      libraries working.  The i915 driver supports the "modeset"
+      module parameter to control whether advanced features are
+      enabled at load time or in legacy fashion.  If compatibility is
+      a concern (e.g. with drivers converted over to the new interfaces
+      from the old ones), care must be taken to prevent incompatible
+      device initialization and control with the currently active
+      userspace drivers.
+    </para>
+    <sect2>
+      <title>Driver private &amp; performance counters</title>
+      <para>
+        The driver private hangs off the main drm_device structure and
+        can be used for tracking various device specific bits of
+        information, like register offsets, command buffer status,
+        register state for suspend/resume, etc.  At load time, a
+        driver can simply allocate one and set drm_device.dev_priv
+        appropriately; at unload the driver can free it and set
+        drm_device.dev_priv to NULL.
+      </para>
+      <para>
+        The DRM supports several counters which can be used for rough
+        performance characterization.  Note that the DRM stat counter
+        system is not often used by applications, and supporting
+        additional counters is completely optional.
+      </para>
+      <para>
+        These interfaces are deprecated and should not be used.  If performance
+        monitoring is desired, the developer should investigate and
+        potentially enhance the kernel perf and tracing infrastructure to export
+        GPU related performance information to performance monitoring
+        tools and applications.
+      </para>
+    </sect2>
+    <sect2>
+      <title>Configuring the device</title>
+      <para>
+        Obviously, device configuration will be device specific.
+        However, there are several common operations: finding a
+        device's PCI resources, mapping them, and potentially setting
+        up an IRQ handler.
+      </para>
+      <para>
+        Finding &amp; mapping resources is fairly straightforward.  The
+        DRM wrapper functions, drm_get_resource_start() and
+        drm_get_resource_len() can be used to find BARs on the given
+        drm_device struct.  Once those values have been retrieved, the
+        driver load function can call drm_addmap() to create a new
+        mapping for the BAR in question.  Note you'll probably want a
+        drm_local_map_t in your driver private structure to track any
+        mappings you create.
+<!-- !Fdrivers/gpu/drm/drm_bufs.c drm_get_resource_* -->
+<!-- !Finclude/drm/drmP.h drm_local_map_t -->
+      </para>
+      <para>
+        if compatibility with other operating systems isn't a concern
+        (DRM drivers can run under various BSD variants and OpenSolaris),
+        native Linux calls can be used for the above, e.g. pci_resource_*
+        and iomap*/iounmap.  See the Linux device driver book for more
+        info.
+      </para>
+      <para>
+        Once you have a register map, you can use the DRM_READn() and
+        DRM_WRITEn() macros to access the registers on your device, or
+        use driver specific versions to offset into your MMIO space
+        relative to a driver specific base pointer (see I915_READ for
+        example).
+      </para>
+      <para>
+        If your device supports interrupt generation, you may want to
+        setup an interrupt handler at driver load time as well.  This
+        is done using the drm_irq_install() function.  If your device
+        supports vertical blank interrupts, it should call
+        drm_vblank_init() to initialize the core vblank handling code before
+        enabling interrupts on your device.  This ensures the vblank related
+        structures are allocated and allows the core to handle vblank events.
+      </para>
+<!--!Fdrivers/char/drm/drm_irq.c drm_irq_install-->
+      <para>
+        Once your interrupt handler is registered (it'll use your
+        drm_driver.irq_handler as the actual interrupt handling
+        function), you can safely enable interrupts on your device,
+        assuming any other state your interrupt handler uses is also
+        initialized.
+      </para>
+      <para>
+        Another task that may be necessary during configuration is
+        mapping the video BIOS.  On many devices, the VBIOS describes
+        device configuration, LCD panel timings (if any), and contains
+        flags indicating device state.  Mapping the BIOS can be done
+        using the pci_map_rom() call, a convenience function that
+        takes care of mapping the actual ROM, whether it has been
+        shadowed into memory (typically at address 0xc0000) or exists
+        on the PCI device in the ROM BAR.  Note that once you've
+        mapped the ROM and extracted any necessary information, be
+        sure to unmap it; on many devices the ROM address decoder is
+        shared with other BARs, so leaving it mapped can cause
+        undesired behavior like hangs or memory corruption.

+      <title>Memory manager initialization</title>
+      <para>
+        In order to allocate command buffers, cursor memory, scanout
+        buffers, etc., as well as support the latest features provided
+        by packages like Mesa and the X.Org X server, your driver
+        should support a memory manager.
+      </para>
+      <para>
+        If your driver supports memory management (it should!), you'll
+        need to set that up at load time as well.  How you intialize
+        it depends on which memory manager you're using, TTM or GEM.

+      <sect3>
+        <title>TTM initialization</title>
+        <para>
+          TTM (for Translation Table Manager) manages video memory and
+          aperture space for graphics devices. TTM supports both UMA devices
+          and devices with dedicated video RAM (VRAM), i.e. most discrete
+          graphics devices.  If your device has dedicated RAM, supporting
+          TTM is desireable.  TTM also integrates tightly with your
+          driver specific buffer execution function.  See the radeon
+          driver for examples.
+        </para>
+        <para>
+          The core TTM structure is the ttm_bo_driver struct.  It contains
+          several fields with function pointers for initializing the TTM,
+          allocating and freeing memory, waiting for command completion
+          and fence synchronization, and memory migration.  See the
+          radeon_ttm.c file for an example of usage.
+        </para>
+        <para>
+          The ttm_global_reference structure is made up of several fields:

+        <programlisting>
+          struct ttm_global_reference {
+                enum ttm_global_types global_type;
+                size_t size;
+                void *object;
+                int (*init) (struct ttm_global_reference *);
+                void (*release) (struct ttm_global_reference *);
+          };
+        </programlisting>
+        <para>
+          There should be one global reference structure for your memory
+          manager as a whole, and there will be others for each object
+          created by the memory manager at runtime.  Your global TTM should
+          have a type of TTM_GLOBAL_TTM_MEM.  The size field for the global
+          object should be sizeof(struct ttm_mem_global), and the init and
+          release hooks should point at your driver specific init and
+          release routines, which will probably eventually call
+          ttm_mem_global_init and ttm_mem_global_release respectively.
+        </para>
+        <para>
+          Once your global TTM accounting structure is set up and initialized
+          (done by calling ttm_global_item_ref on the global object you
+          just created), you'll need to create a buffer object TTM to
+          provide a pool for buffer object allocation by clients and the
+          kernel itself.  The type of this object should be TTM_GLOBAL_TTM_BO,

+        <para>
+          GEM is an alternative to TTM, designed specifically for UMA
+          devices.  It has simpler initialization and execution requirements
+          than TTM, but has no VRAM management capability.  Core GEM
+          initialization is comprised of a basic drm_mm_init call to create
+          a GTT DRM MM object, which provides an address space pool for
+          object allocation.  In a KMS configuration, the driver will
+          need to allocate and initialize a command ring buffer following
+          basic GEM initialization.  Most UMA devices have a so-called
+          "stolen" memory region, which provides space for the initial
+          framebuffer and large, contiguous memory regions required by the
+          device.  This space is not typically managed by GEM, and must
+          be initialized separately into its own DRM MM object.
+        </para>
+        <para>
+          Initialization will be driver specific, and will depend on
+          the architecture of the device.  In the case of Intel
+          integrated graphics chips like 965GM, GEM initialization can
+          be done by calling the internal GEM init function,
+          i915_gem_do_init().  Since the 965GM is a UMA device
+          (i.e. it doesn't have dedicated VRAM), GEM will manage
+          making regular RAM available for GPU operations.  Memory set
+          aside by the BIOS (called "stolen" memory by the i915

+            devices with PC-style architectures (i.e. a set of display planes
+            for feeding pixels to encoders which are in turn routed to
+            connectors).  Devices with more complex requirements needing

+<!--!Edrivers/char/drm/drm_irq.c-->
+    </para>
+    <para>
+      DRM_IOCTL_WAIT_VBLANK takes a struct drm_wait_vblank structure

+    </para>
+    <para>
+      DRM_IOCTL_MODESET_CTL should be called by application level
+      drivers before and after mode setting, since on many devices the
+      vertical blank counter will be reset at that time.  Internally,
+      the DRM snapshots the last vblank count when the ioctl is called
+      with the _DRM_PRE_MODESET command so that the counter won't go
+      backwards (which is dealt with when _DRM_POST_MODESET is used).
+    </para>
+    <para>
+      To support the functions above, the DRM core provides several
+      helper functions for tracking vertical blank counters, and
+      requires drivers to provide several callbacks:
+      get_vblank_counter(), enable_vblank() and disable_vblank().  The
+      core uses get_vblank_counter() to keep the counter accurate
+      across interrupt disable periods.  It should return the current
+      vertical blank event count, which is often tracked in a device
+      register.  The enable and disable vblank callbacks should enable
+      and disable vertical blank interrupts, respectively.  In the
+      absence of DRM clients waiting on vblank events, the core DRM
+      code will use the disable_vblank() function to disable
+      interrupts, which saves power.  They'll be re-enabled again when
+      a client calls the vblank wait ioctl above.
+    </para>
+    <para>
+      Devices that don't provide a count register can simply use an
+      internal atomic counter incremented on every vertical blank

+      </para>
+      <para>
+        GEM-enabled drivers must provide gem_init_object() and
+        gem_free_object() callbacks to support the core memory
+        allocation routines.  They should also provide several driver
+        specific ioctls to support command execution, pinning, buffer
+        read &amp; write, mapping, and domain ownership transfers.
+      </para>
+      <para>
+        On a fundamental level, GEM involves several operations: memory
+        allocation and freeing, command execution, and aperture management
+        at command execution time.  Buffer object allocation is relatively
+        straightforward and largely provided by Linux's shmem layer, which
+        provides memory to back each object.  When mapped into the GTT
+        or used in a command buffer, the backing pages for an object are
+        flushed to memory and marked write combined so as to be coherent
+        with the GPU.  Likewise, when the GPU finishes rendering to an object,
+        if the CPU accesses it, it must be made coherent with the CPU's view
+        of memory, usually involving GPU cache flushing of various kinds.
+        This core CPU&lt;-&gt;GPU coherency management is provided by the GEM
+        set domain function, which evaluates an object's current domain and
+        performs any necessary flushing or synchronization to put the object
+        into the desired coherency domain (note that the object may be busy,
+        i.e. an active render target; in that case the set domain function
+        will block the client and wait for rendering to complete before
+        performing any necessary flushing operations).
+      </para>
+      <para>
+        Perhaps the most important GEM function is providing a command
+        execution interface to clients.  Client programs construct command
+        buffers containing references to previously allocated memory objects
+        and submit them to GEM.  At that point, GEM will take care to bind
+        all the objects into the GTT, execute the buffer, and provide
+        necessary synchronization between clients accessing the same buffers.
+        This often involves evicting some objects from the GTT and re-binding
+        others (a fairly expensive operation), and providing relocation
+        support which hides fixed GTT offsets from clients.  Clients must
+        take care not to submit command buffers that reference more objects
+        than can fit in the GTT or GEM will reject them and no rendering
+        will occur.  Similarly, if several objects in the buffer require
+        fence registers to be allocated for correct rendering (e.g. 2D blits
+        on pre-965 chips), care must be taken not to require more fence
+        registers than are available to the client.  Such resource management
+        should be abstracted from the client in libdrm.

+      At the core of the DRM output management code is a set of
+      structures representing CRTCs, encoders and connectors.
+    </para>
+    <para>
+      A CRTC is an abstraction representing a part of the chip that
+      contains a pointer to a scanout buffer.  Therefore, the number
+      of CRTCs available determines how many independent scanout
+      buffers can be active at any given time.  The CRTC structure
+      contains several fields to support this: a pointer to some video
+      memory, a display mode, and an (x, y) offset into the video
+      memory to support panning or configurations where one piece of
+      video memory spans multiple CRTCs.
+    </para>
+    <para>
+      An encoder takes pixel data from a CRTC and converts it to a
+      format suitable for any attached connectors.  On some devices,
+      it may be possible to have a CRTC send data to more than one
+      encoder.  In that case, both encoders would receive data from
+      the same scanout buffer, resulting in a "cloned" display
+      configuration across the connectors attached to each encoder.
+    </para>
+    <para>
+      A connector is the final destination for pixel data on a device,
+      and usually connects directly to an external display device like
+      a monitor or laptop panel.  A connector can only be attached to
+      one encoder at a time.  The connector is also the structure
+      where information about the attached display is kept, so it
+      contains fields for display data, EDID data, DPMS &amp;
+      connection status, and information about modes supported on the

+      and ultimately the connector(s) in the configuration.  A framebuffer
+      is fundamentally a driver specific memory object, made into an opaque
+      handle by the DRM addfb function.  Once an fb has been created this

+ * Intel GTT (Graphics Translation Table) routines
+ *
+ * Caveat: This driver implements the linux agp interface, but this is far from
+ * a agp driver! GTT support ended up here for purely historical reasons: The
+ * old userspace intel graphics drivers needed an interface to map memory into
+ * the GTT. And the drm provides a default interface for graphic devices sitting
+ * on an agp port. So it made sense to fake the GTT support as an agp port to
+ * avoid having to create a new api.
+ *
+ * With gem this does not make much sense anymore, just needlessly complicates
+ * the code. But as long as the old graphics stack is still support, it's stuck
+ * here.

+ * If we have Intel graphics, we're not going to have anything other than

+ * on the Intel IOMMU support (CONFIG_DMAR).
