| # framebuffer |
| |
| **NOTE**: This is not a general purpose library. Clients should be aware of this |
| library's limitations before using it. |
| |
| This library provides a simple framebuffer abstraction on top of the Zircon display |
| APIs. Applications can use this library to provide a low level UI on systems which lack |
| a normal UI framework. **Important**: When a normal UI framework is running, this |
| library will not be able to bind to the display. |
| |
| The library supports two modes of operation: a single buffer mode where the library |
| initializes the display hardware with a single, linear VMO that clients can then |
| render to in place, and a page flip mode where the client can provide multiple VMO |
| backed images and flip between them. Clients are responsible for ensuring buffers |
| are kept coherent with main memory. |
| |
| The library does not expose support for multiple monitors, hotplugging, modesetting, |
| or 2D hardware composition. Applications which want these features should use the Zircon |
| display APIs directly. |
