+ <title>Introduction</title>
+ <para>
+ 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.
+ </para>
+ <para>
+ A note on versions: this guide covers features found in the DRM
+ tree, including the TTM memory manager, output configuration and
+ mode setting, and the new vblank internals, in addition to all
+ the regular features found in current kernels.

+ <title>DRM Internals</title>
+ <para>
+ 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>
+ <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 & fencing, suspend/resume support, and DMA
+ services.
+ </para>
+ <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.
+ </para>
+
+ <!-- Internals: driver init -->
+
+ <sect1>
+ <title>Driver initialization</title>
+ <para>
+ Before calling the DRM initialization routines, the driver must
+ first create and fill out a struct drm_device structure.

+
+ <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 & 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 & 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 & 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 & 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 initialize
+ it depends on which memory manager you're using, TTM or GEM.
+ </para>
+ <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 desirable. 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:
+ </para>
+ <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,
+ and its size should be sizeof(struct ttm_bo_global). Again,
+ driver specific init and release functions can be provided,
+ likely eventually calling ttm_bo_global_init and
+ ttm_bo_global_release, respectively. Also like the previous
+ object, ttm_global_item_ref is used to create an initial reference
+ count for the TTM, which will call your initialization function.
+ </para>
+ </sect3>
+ <sect3>
+ <title>GEM initialization</title>
+ <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
+ driver) will be managed by the DRM memrange allocator; the
+ rest of the aperture will be managed by GEM.

+ 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

+ backwards (which is dealt with when _DRM_POST_MODESET is used).

+ <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

+ register. The enable and disable vblank callbacks should enable

+ <para>
+ GEM is an Intel project, authored by Eric Anholt and Keith

+ </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 & 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<->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.

+ <title>Output management</title>
+ <para>
+ At the core of the DRM output management code is a set of

+ </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

+ <title>Suspend/resume</title>
+ <para>
+ The DRM core provides some suspend/resume code, but drivers
+ wanting full suspend/resume support should provide save() and
+ restore() functions. These will be called at suspend,
+ hibernate, or resume time, and should perform any state save or
+ restore required by your device across suspend or hibernate
+ states.
+ </para>
+ </sect1>
+
+ <sect1>
+ <title>DMA services</title>
+ <para>
+ This should cover how DMA mapping etc. is supported by the core.
+ These functions are deprecated and should not be used.
+ </para>

+
+ <chapter id="drmExternals">
+ <title>Userland interfaces</title>
+ <para>
+ The DRM core exports several interfaces to applications,
+ generally intended to be used through corresponding libdrm
+ wrapper functions. In addition, drivers export device specific
+ interfaces for use by userspace drivers & device aware
+ applications through ioctls and sysfs files.
+ </para>
+ <para>
+ External interfaces include: memory mapping, context management,
+ DMA operations, AGP management, vblank control, fence
+ management, memory management, and output management.
+ </para>
+ <para>
+ Cover generic ioctls and sysfs layout here. Only need high
+ level info, since man pages will cover the rest.

+ * 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.
