+## jAcceleratorPluginInitialize
+
+This packet requests initialization data from all accelerator plugins
+installed in lldb-server. Accelerator plugins allow lldb-server to support
+debugging of hardware accelerators (e.g. GPUs, FPGAs) alongside the native
+host process. This packet is only sent when the server reports the
+`accelerator-plugins+` feature in its `qSupported` response.

+```
+
+Each `accelerator_action` is a JSON object with the following required fields:
+
+| Key            | Type    | Description |
+|----------------|---------|-------------|
+| `plugin_name`  | string  | Unique name identifying the accelerator plugin (e.g. `"mock"`, `"amdgpu"`). Each installed plugin has a distinct name. |
+| `session_name` | string  | Name for the DAP debug session associated with this plugin. May be empty. |
+| `identifier`   | integer | Unique identifier for this action. Each action from a given plugin has a distinct identifier. |
+
+There can be multiple accelerator plugins installed, each with a unique
+`plugin_name`. The response is a JSON array with one entry per installed
+plugin.
+
+Example:
+```
+LLDB SENDS:    jAcceleratorPluginInitialize
+STUB REPLIES:  [{"plugin_name":"mock","session_name":"","identifier":0}]
+```
+
+If no accelerator plugins are installed, the server does not advertise the
+`accelerator-plugins+` feature and this packet should not be sent.
+
+In future patches, each `accelerator_action` will include additional fields
+such as breakpoints to set in the native process, connection info for
+secondary debug sessions, and synchronization options.
