At the core of every DRM driver is a <structname>drm_driver</structname>
structure. Drivers typically statically initialize a drm_driver structure,
- and then pass it to one of the <function>drm_*_init()</function> functions
- to register it with the DRM subsystem.

- Newer drivers that no longer require a <structname>drm_bus</structname>

- <para>
- New drivers that no longer rely on the services provided by the
- <structname>drm_bus</structname> structure can call the low-level
- device registration functions directly. The
- <function>drm_dev_alloc()</function> function can be used to allocate
- and initialize a new <structname>drm_device</structname> structure.
- Drivers will typically want to perform some additional setup on this
- structure, such as allocating driver-specific data and storing a
- pointer to it in the DRM device's <structfield>dev_private</structfield>
- field. Drivers should also set the device's unique name using the
- <function>drm_dev_set_unique()</function> function. After it has been
- set up a device can be registered with the DRM subsystem by calling
- <function>drm_dev_register()</function>. This will cause the device to
- be exposed to userspace and will call the driver's
- <structfield>.load()</structfield> implementation. When a device is
- removed, the DRM device can safely be unregistered and freed by calling
- <function>drm_dev_unregister()</function> followed by a call to
- <function>drm_dev_unref()</function>.

<title>Driver Load</title>
- <para>
- The <methodname>load</methodname> method is the driver and device
- initialization entry point. The method is responsible for allocating and
- initializing driver private data, performing resource allocation and
- mapping (e.g. acquiring
- clocks, mapping registers or allocating command buffers), initializing
- the memory manager (<xref linkend="drm-memory-management"/>), installing
- the IRQ handler (<xref linkend="drm-irq-registration"/>), setting up
- vertical blanking handling (<xref linkend="drm-vertical-blank"/>), mode
- setting (<xref linkend="drm-mode-setting"/>) and initial output
- configuration (<xref linkend="drm-kms-init"/>).
- </para>
- <note><para>
- If compatibility is a concern (e.g. with drivers converted over from
- User Mode Setting to Kernel Mode Setting), care must be taken to prevent
- device initialization and control that is incompatible with currently
- active userspace drivers. 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 user-level drivers
- unaware of memory management 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.
- </para></note>
- <synopsis>int (*load) (struct drm_device *, unsigned long flags);</synopsis>
- <para>
- The method takes two arguments, a pointer to the newly created
- <structname>drm_device</structname> and flags. The flags are used to
- pass the <structfield>driver_data</structfield> field of the device id
- corresponding to the device passed to <function>drm_*_init()</function>.
- Only PCI devices currently use this, USB and platform DRM drivers have
- their <methodname>load</methodname> method called with flags to 0.
- </para>
- <sect3>
- <title>Driver Private Data</title>
- <para>
- The driver private hangs off the main
- <structname>drm_device</structname> 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 may simply allocate one and set
- <structname>drm_device</structname>.<structfield>dev_priv</structfield>
- appropriately; it should be freed and
- <structname>drm_device</structname>.<structfield>dev_priv</structfield>
- set to NULL when the driver is unloaded.

+ * DOC: driver instance overview
+ *
+ * A device instance for a drm driver is represented by struct &drm_device. This
+ * is allocated with drm_dev_alloc(), usually from bus-specific ->probe()
+ * callbacks implemented by the driver. The driver then needs to initialize all
+ * the various subsystems for the drm device like memory management, vblank
+ * handling, modesetting support and intial output configuration plus obviously
+ * initialize all the corresponding hardware bits. An important part of this is
+ * also calling drm_dev_set_unique() to set the userspace-visible unique name of
+ * this device instance. Finally when everything is up and running and ready for
+ * userspace the device instance can be published using drm_dev_register().
+ *
+ * There is also deprecated support for initalizing device instances using
+ * bus-specific helpers and the ->load() callback. But due to
+ * backwards-compatibility needs the device instance have to be published too
+ * early, which requires unpretty global locking to make safe and is therefore
+ * only support for existing drivers not yet converted to the new scheme.
+ *
+ * When cleaning up a device instance everything needs to be done in reverse:
+ * First unpublish the device instance with drm_dev_unregister(). Then clean up
+ * any other resources allocated at device initialization and drop the driver's
+ * reference to &drm_device using drm_dev_unref().
+ *
+ * Note that the lifetime rules for &drm_device instance has still a lot of
+ * historical baggage. Hence use the reference counting provided by
+ * drm_dev_ref() and drm_dev_unref() only carefully.
+ *
+ * Also note that embedding of &drm_device is currently not (yet) supported (but
+ * it would be easy to add). Drivers can store driver-private data in the
+ * dev_priv field of &drm_device.

+/**
+ * DOC: GuC Client
+ *
+ * i915_guc_client:
+ * We use the term client to avoid confusion with contexts. A i915_guc_client is
+ * equivalent to GuC object guc_context_desc. This context descriptor is
+ * allocated from a pool of 1024 entries. Kernel driver will allocate doorbell
+ * and workqueue for it. Also the process descriptor (guc_process_desc), which
+ * is mapped to client space. So the client can write Work Item then ring the
+ * doorbell.
+ *
+ * To simplify the implementation, we allocate one gem object that contains all
+ * pages for doorbell, process descriptor and workqueue.
+ *
+ * The Scratch registers:
+ * There are 16 MMIO-based registers start from 0xC180. The kernel driver writes
+ * a value to the action register (SOFT_SCRATCH_0) along with any data. It then
+ * triggers an interrupt on the GuC via another register write (0xC4C8).
+ * Firmware writes a success/fail code back to the action register after
+ * processes the request. The kernel driver polls waiting for this update and
+ * then proceeds.
+ * See host2guc_action()
+ *
+ * Doorbells:
+ * Doorbells are interrupts to uKernel. A doorbell is a single cache line (QW)
+ * mapped into process space.
+ *
+ * Work Items:
+ * There are several types of work items that the host may place into a
+ * workqueue, each with its own requirements and limitations. Currently only
+ * WQ_TYPE_INORDER is needed to support legacy submission via GuC, which
+ * represents in-order queue. The kernel driver packs ring tail pointer and an
+ * ELSP context descriptor dword into Work Item.
+ * See guc_add_workqueue_item()
+ *

+ * ExecList submission.
+ *
+ * Firmware versioning:
+ * The firmware build process will generate a version header file with major and
+ * minor version defined. The versions are built into CSS header of firmware.
+ * i915 kernel driver set the minimal firmware version required per platform.
+ * The firmware installation package will install (symbolic link) proper version
+ * of firmware.
+ *
+ * GuC address space:
+ * GuC does not allow any gfx GGTT address that falls into range [0, WOPCM_TOP),
+ * which is reserved for Boot ROM, SRAM and WOPCM. Currently this top address is
+ * 512K. In order to exclude 0-512K address space from GGTT, all gfx objects
+ * used by GuC is pinned with PIN_OFFSET_BIAS along with size of WOPCM.
+ *
+ * Firmware log:
+ * Firmware log is enabled by setting i915.guc_log_level to non-negative level.
+ * Log data is printed out via reading debugfs i915_guc_log_dump. Reading from
+ * i915_guc_load_status will print out firmware loading status and scratch
+ * registers value.

+/**
+ * DOC: VC4 CRTC module
+ *
+ * In VC4, the Pixel Valve is what most closely corresponds to the
+ * DRM's concept of a CRTC. The PV generates video timings from the
+ * output's clock plus its configuration. It pulls scaled pixels from
+ * the HVS at that timing, and feeds it to the encoder.
+ *
+ * However, the DRM CRTC also collects the configuration of all the
+ * DRM planes attached to it. As a result, this file also manages
+ * setup of the VC4 HVS's display elements on the CRTC.
+ *
+ * The 2835 has 3 different pixel valves. pv0 in the audio power
+ * domain feeds DSI0 or DPI, while pv1 feeds DS1 or SMI. pv2 in the
+ * image domain can feed either HDMI or the SDTV controller. The
+ * pixel valve chooses from the CPRMAN clocks (HSM for HDMI, VEC for
+ * SDTV, etc.) according to which output type is chosen in the mux.
+ *
+ * For power management, the pixel valve's registers are all clocked
+ * by the AXI clock, while the timings and FIFOs make use of the
+ * output-specific clock. Since the encoders also directly consume
+ * the CPRMAN clocks, and know what timings they need, they are the
+ * ones that set the clock.

+ * The HVS is the piece of hardware that does translation, scaling,

+ * (CRTC). It operates at the system clock rate (the system audio
+ * clock gate, specifically), which is much higher than the pixel
+ * clock rate.
+ *
+ * There is a single global HVS, with multiple output FIFOs that can
+ * be consumed by the PVs. This file just manages the resources for
+ * the HVS, while the vc4_crtc.c code actually drives HVS setup for
+ * each CRTC.

+/**
+ * DOC: Overview
+ *
+ * vga_switcheroo is the Linux subsystem for laptop hybrid graphics.
+ * These come in two flavors:
+ *
+ * * muxed: Dual GPUs with a multiplexer chip to switch outputs between GPUs.
+ * * muxless: Dual GPUs but only one of them is connected to outputs.
+ * The other one is merely used to offload rendering, its results
+ * are copied over PCIe into the framebuffer. On Linux this is
+ * supported with DRI PRIME.
+ *
+ * Hybrid graphics started to appear in the late Naughties and were initially
+ * all muxed. Newer laptops moved to a muxless architecture for cost reasons.
+ * A notable exception is the MacBook Pro which continues to use a mux.
+ * Muxes come with varying capabilities: Some switch only the panel, others
+ * can also switch external displays. Some switch all display pins at once
+ * while others can switch just the DDC lines. (To allow EDID probing
+ * for the inactive GPU.) Also, muxes are often used to cut power to the
+ * discrete GPU while it is not used.
+ *
+ * DRM drivers register GPUs with vga_switcheroo, these are heretoforth called
+ * clients. The mux is called the handler. Muxless machines also register a
+ * handler to control the power state of the discrete GPU, its ->switchto
+ * callback is a no-op for obvious reasons. The discrete GPU is often equipped
+ * with an HDA controller for the HDMI/DP audio signal, this will also
+ * register as a client so that vga_switcheroo can take care of the correct
+ * suspend/resume order when changing the discrete GPU's power state. In total
+ * there can thus be up to three clients: Two vga clients (GPUs) and one audio
+ * client (on the discrete GPU). The code is mostly prepared to support
+ * machines with more than two GPUs should they become available.
+ * The GPU to which the outputs are currently switched is called the
+ * active client in vga_switcheroo parlance. The GPU not in use is the
+ * inactive client.
