TPO TPG110 Panel
================
-This binding builds on the DPI bindings, adding a few properties
-as a superset of a DPI. See panel-dpi.txt for the required DPI
-bindings.
+This panel driver is a component that acts as an intermediary
+between an RGB output and a variety of panels. The panel
+driver is strapped up in electronics to the desired resolution
+and other properties, and has a control interface over 3WIRE
+SPI. By talking to the TPG110 over SPI, the strapped properties
+can be discovered and the hardware is therefore mostly
+self-describing.
+
+ +--------+
+SPI -> | TPO | -> physical display
+RGB -> | TPG110 |
+ +--------+
+
+If some electrical strap or alternate resolution is desired,
+this can be set up by taking software control of the display
+over the SPI interface. The interface can also adjust
+for properties of the display such as gamma correction and
+certain electrical driving levels.
+
+The TPG110 does not know the physical dimensions of the panel
+connected, so this needs to be specified in the device tree.
+
+It requires a GPIO line for control of its reset line.
+
+The serial protocol has line names that resemble I2C but the
+protocol is not I2C but 3WIRE SPI.
Required properties:
-- compatible : "tpo,tpg110"

+- height-mm : see display/panel/panel-common.txt
-Required nodes:
-- Video port for DPI input, see panel-dpi.txt

+The device needs to be a child of an SPI bus, see

+drm/amd/display - Display Core (DC)
+===================================
+
+*placeholder - general description of supported platforms, what dc is, etc.*
+
+Because it is partially shared with other operating systems, the Display Core
+Driver is divided in two pieces.
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+ hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+ amdgpu base driver and DRM are implemented here.
+
+It doesn't help that the entire package is frequently referred to as DC. But
+with the context in mind, it should be clear.
+
+When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
+supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
+Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
+
+To determine if DC is loaded, search dmesg for the following entry:
+
+``Display Core initialized with <version number here>``

-Switch from reference/unreference to get/put
---------------------------------------------
-For some reason DRM core uses ``reference``/``unreference`` suffixes for
-refcounting functions, but kernel uses ``get``/``put`` (e.g.
-``kref_get``/``put()``). It would be good to switch over for consistency, and
-it's shorter. Needs to be done in 3 steps for each pair of functions:
+Remove custom dumb_map_offset implementations
+---------------------------------------------
-* Create new ``get``/``put`` functions, define the old names as compatibility
- wrappers
-* Switch over each file/driver using a cocci-generated spatch.
-* Once all users of the old names are gone, remove them.
+All GEM based drivers should be using drm_gem_create_mmap_offset() instead.
+Audit each individual driver, make sure it'll work with the generic
+implementation (there's lots of outdated locking leftovers in various
+implementations), and then remove it.
-This way drivers/patches in the progress of getting merged won't break.

+Some IGT test cases are failing. Need to analyze why and fix the issues:

+- flip-vs-blocking-wf-vblank

+
+Runtime Configuration
+---------------------
+
+We want to be able to reconfigure vkms instance without having to reload the
+module. Use/Test-cases:
+
+- Hotplug/hotremove connectors on the fly (to be able to test DP MST handling of
+ compositors).
+
+- Configure planes/crtcs/connectors (we'd need some code to have more than 1 of
+ them first).
+
+- Change output configuration: Plug/unplug screens, change EDID, allow changing
+ the refresh rate.
+
+The currently proposed solution is to expose vkms configuration through
+configfs. All existing module options should be supported through configfs too.
+
+Add Plane Features
+------------------
+
+There's lots of plane features we could add support for:
+
+- Real overlay planes, not just cursor.
+
+- Full alpha blending on all planes.
+
+- Rotation, scaling.
+
+- Additional buffer formats, especially YUV formats for video like NV12.
+ Low/high bpp RGB formats would also be interesting.
+
+- Async updates (currently only possible on cursor plane using the legacy cursor
+ api).
+
+For all of these, we also want to review the igt test coverage and make sure all
+relevant igt testcases work on vkms.
+
+Writeback support
+-----------------
+
+Currently vkms only computes a CRC for each frame. Once we have additional plane
+features, we could write back the entire composited frame, and expose it as:
+
+- Writeback connector. This is useful for testing compositors if you don't have
+ hardware with writeback support.
+
+- As a v4l device. This is useful for debugging compositors on special vkms
+ configurations, so that developers see what's really going on.
+
+Prime Buffer Sharing
+--------------------
+
+We already have vgem, which is a gem driver for testing rendering, similar to
+how vkms is for testing the modeset side. Adding buffer sharing support to vkms
+allows us to test them together, to test synchronization and lots of other
+features. Also, this allows compositors to test whether they work correctly on
+SoC chips, where the display and rendering is very often split between 2
+drivers.
+
+Output Features
+---------------
+
+- Variable refresh rate/freesync support. This probably needs prime buffer
+ sharing support, so that we can use vgem fences to simulate rendering in
+ testing. Also needs support to specify the EDID.
+
+- Add support for link status, so that compositors can validate their runtime
+ fallbacks when e.g. a Display Port link goes bad.
+
+- All the hotplug handling describe under "Runtime Configuration".
+
+Atomic Check using eBPF
+-----------------------
+
+Atomic drivers have lots of restrictions which are not exposed to userspace in
+any explicit form through e.g. possible property values. Userspace can only
+inquiry about these limits through the atomic IOCTL, possibly using the
+TEST_ONLY flag. Trying to add configurable code for all these limits, to allow
+compositors to be tested against them, would be rather futile exercise. Instead
+we could add support for eBPF to validate any kind of atomic state, and
+implement a library of different restrictions.
+
+This needs a bunch of features (plane compositing, multiple outputs, ...)
+enabled already to make sense.

+ * DM provides another layer of IRQ management on top of what the base driver
+ * already provides. This is something that could be cleaned up, and is a
+ * future TODO item.
+ *
+ * The base driver provides IRQ source registration with DRM, handler
+ * registration into the base driver's IRQ table, and a handler callback
+ * amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
+ * handler looks up the IRQ table, and calls the respective
+ * &amdgpu_irq_src_funcs.process hookups.
+ *
+ * What DM provides on top are two IRQ tables specifically for top-half and
+ * bottom-half IRQ handling, with the bottom-half implementing workqueues:
+ *
+ * - &amdgpu_display_manager.irq_handler_list_high_tab
+ * - &amdgpu_display_manager.irq_handler_list_low_tab
+ *
+ * They override the base driver's IRQ table, and the effect can be seen

+/**
+ * DOC: atomic state reset and initialization
+ *
+ * Both the drm core and the atomic helpers assume that there is always the full
+ * and correct atomic software state for all connectors, CRTCs and planes
+ * available. Which is a bit a problem on driver load and also after system
+ * suspend. One way to solve this is to have a hardware state read-out
+ * infrastructure which reconstructs the full software state (e.g. the i915
+ * driver).
+ *
+ * The simpler solution is to just reset the software state to everything off,
+ * which is easiest to do by calling drm_mode_config_reset(). To facilitate this
+ * the atomic helpers provide default reset implementations for all hooks.
+ *
+ * On the upside the precise state tracking of atomic simplifies system suspend
+ * and resume a lot. For drivers using drm_mode_config_reset() a complete recipe
+ * is implemented in drm_atomic_helper_suspend() and drm_atomic_helper_resume().
+ * For other drivers the building blocks are split out, see the documentation
+ * for these functions.

+ *
+ * Makes a copy of the current atomic state by looping over all objects and
+ * duplicating their respective states. This is used for example by suspend/
+ * resume support code to save the state prior to suspend such that it can
+ * be restored upon resume.
+ *
+ * Note that this treats atomic state as persistent between save and restore.
+ * Drivers must make sure that this is possible and won't result in confusion
+ * or erroneous behaviour.
+ *
+ * Note that if callers haven't already acquired all modeset locks this might
+ * return -EDEADLK, which must be handled by calling drm_modeset_backoff().
+ *
+ * Returns:
+ * A pointer to the copy of the atomic state object on success or an
+ * ERR_PTR()-encoded error code on failure.

+ * A few other ideas were considered:

+ * consider virtio.
+ * Seems like a bigger hack than what we have already.
+ *
+ * - Point drm_device::dev to the parent of the virtio_device
+ * Semantic changes:
+ * * Using the wrong device for i2c, framebuffer_alloc and
+ * prime import.
+ * Visual changes:
+ * * Helpers such as DRM_DEV_ERROR, dev_info, drm_printer,
+ * will print the wrong information.
+ *
+ * We could address the latter issues, by introducing
+ * drm_device::bus_dev, ... which would be used solely for this.
