# Bootloader API — provides the `entry_point!` macro and `BootInfo` struct.
# This defines the contract between the bootloader and our kernel.
bootloader_api = "0.11"

# x86_64 hardware abstractions — provides safe wrappers for CPU instructions
# (like `hlt`, interrupt control) and hardware structures (page tables, IDT).
x86_64 = "0.14.2"

# Spinlock — a mutex that busy-waits instead of sleeping.
# Necessary in kernel space where there is no scheduler to block a thread.
spin = "0.9.8"

# Lazy static — allows initializing global statics at runtime.
# The `spin_no_std` feature uses spinlocks instead of std::sync::Once.
lazy_static = { version = "1.5.0", features = ["spin_no_std"] }

# UART 16550 serial port driver — for sending text to the host terminal.
uart_16550 = "0.3.0"

# Volatile — ensures the compiler doesn't optimize away MMIO writes.
# Used for VGA text buffer and other hardware registers.
volatile = "0.5.1"

# wasmi — lightweight WebAssembly interpreter for no_std environments.
# This is the core of our universal execution layer — apps compiled to WASM
# can run on any architecture (x86, ARM, RISC-V) without recompilation.
# `default-features = false` disables std, enabling bare-metal usage.

# 'alloc' feature is required for VirtioNet to allocate queues.

# Supports TCP, UDP, DHCP, and more in a no_std environment.
