+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.

+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>``

+- 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.
