+### HVM/PVH Boot on x86_64
+
+In the DragonOS note segment, there is a PVH header that allows QEMU to boot the DragonOS kernel using the ``-kernel`` parameter.
+
+## RISC-V 64
+
+DragonOS's boot process on RISC-V 64 is as follows:
+
+opensbi --> uboot --> DragonStub --> kernel
+
+This boot process decouples the DragonOS kernel from specific hardware boards, enabling the same binary file to boot and run on different hardware boards.
+
+## Kernel Boot Callbacks
+
+DragonOS abstracts the kernel bootloader, which is represented by the trait ``BootCallbacks``.
+Different bootloaders implement the corresponding callback to initialize the kernel's bootParams or other data structures.
+
+When the kernel boots, it automatically registers callbacks based on the type of bootloader. And at the appropriate time, it calls these callback functions.

+# Kernel Boot Command Line Parameters
+
+:::{note}
+Author:  
+- Longjin <longjin@DragonOS.org>
+:::
+
+## Overview
+
+&emsp;&emsp;The DragonOS kernel boot command line parameter parsing module aims to provide support for parsing kernel boot command line parameters similar to Linux, enabling more flexible behavior for the kernel. This module allows the kernel to receive and parse command line parameters at boot time, and execute corresponding callback functions or set environment variables based on the type of parameters.
+
+:::{note}
+Callback functions are not supported temporarily.
+:::
+
+## Design
+
+### Parameter Types
+
+Kernel boot command line parameters are divided into three types:
+
+- Arg type
+- KV type
+- EarlyKV type
+
+#### Arg Type
+
+Arg type parameters have only a name and no value. They are divided into the following two types:
+
+- ArgNormal: The default value is `false`. If the parameter is present in the command line, it will be set to `true`.
+- ArgInv: The default value is `true`. If the parameter is present in the command line, it will be set to `false`.
+
+#### KV Type
+
+KV type parameters are represented in the command line as `name=value`, `value` separated by commas. Kernel modules can provide default values for these parameters.
+
+#### EarlyKV Type
+
+EarlyKV type parameters are similar to KV type parameters, but they are parsed before memory management initialization.
+
+### Module Flags
+
+Module flags are similar to `usbprobe.xxxx`.
+
+### Parameter Declaration
+
+Provides macros to declare kernel command line parameters.
+### procfs Support
+
+:::{note}
+TODO: Display the current kernel's boot command line parameters under `/proc/cmdline`.
+:::
+
+## Macros for Declaring Kernel Boot Command Line Parameters
+
+### Arg Type Parameter Declaration
+```rust
+kernel_cmdline_param_arg!(varname, name, default_bool, inv);
+```
+- `varname`: The variable name of the parameter
+- `name`: The name of the parameter
+- `default_bool`: The default value
+- `inv`: Whether to invert
+
+### KV Type Parameter Declaration
+
+```rust
+kernel_cmdline_param_kv!(varname, name, default_str);
+```
+
+- `varname`: The variable name of the parameter
+- `name`: The name of the parameter
+- `default_str`: The default value
+
+### KV Type Parameter Declaration Before Memory Management Initialization
+
+```rust
+kernel_cmdline_param_early_kv!(varname, name, default_str);
+```
+
+- `varname`: The variable name of the parameter
+- `name`: The name of the parameter
+- `default_str`: The default value
+
+## Example
+
+The following example demonstrates how to declare and use KV type parameters:
+```rust
+kernel_cmdline_param_kv!(ROOTFS_PATH_PARAM, root, "");
+if let Some(rootfs_dev_path) = ROOTFS_PATH_PARAM.value_str() {
+    .......
+} else {
+    .......
+};
+```
+
+### Usage
+
+1. In the kernel code, use the `kernel_cmdline_param_kv!` macro to declare the required KV type parameters.
+2. During kernel initialization, retrieve the parameter value through the `value_str()` or `value_bool()` method of the parameter.
+3. Execute corresponding operations based on the parameter value.
+
+By following these steps, developers can flexibly use kernel boot command line parameters to control kernel behavior.
+
+## TODO
+
+- Support displaying the current kernel's boot command line parameters under `/proc/cmdline` (requires procfs refactoring)
+- Support setting callback functions to set parameter values
