- Added serial output messages in `enter_baremetal` and `efi_main` to aid debugging during boot. - Expanded the PS/2 keyboard driver with full ASCII support and scan code handling, including initialization and state management. - Implemented assembly routines for PS/2 port I/O operations, including reading status, writing commands, and flushing the output buffer. - Updated embedded relocation data for the bootloader to reflect changes in the binary layout. - Improved error handling in memory allocation and exit boot services calls.
- Introduced `SpawnProcess` variant in `CommandResult` enum. - Implemented `exec` and `run` commands in the `execute` function to handle process spawning. - Updated help text to include usage instructions for the new command. feat(shell): update ShellAction enum for process spawning - Added `SpawnProcess` variant to `ShellAction` enum. - Updated command handling in the `Shell` struct to accommodate the new action. feat(device): implement in-memory block device - Created `MemBlockDevice` struct for zero-copy reads/writes. - Implemented `BlockIo` trait for `MemBlockDevice` to handle block operations. feat(vfs): initialize root filesystem on memory-backed block device - Added `FsGlobal` struct to manage filesystem state. - Implemented `init_root_fs` function to format and mount the filesystem. feat(hwinit): add ELF64 parser and user-process loader - Implemented ELF64 parsing and loading functionality for x86-64 architecture. - Added functions to validate ELF headers, read program headers, and load segments into memory. feat(hwinit): create kernel stdin buffer for keyboard input - Implemented a lock-free SPSC ring buffer for handling keyboard input. - Added functions for pushing bytes into the buffer and reading from it. feat(libmorpheus): create userspace library for syscall wrappers - Established `libmorpheus` crate for userspace applications to interact with kernel services. - Implemented basic syscall wrappers for file operations, process management, and I/O. feat(libmorpheus): add entry point and panic handler for user processes - Defined `_start` entry point for user binaries and a minimal panic handler. feat(libmorpheus): implement filesystem operations in userspace library - Added high-level wrappers for filesystem syscalls including open, read, write, and delete operations. feat(libmorpheus): add raw syscall wrappers for inline assembly - Created thin wrappers around the `syscall` instruction for various system calls. chore: add target configuration for x86_64 architecture - Created `x86_64-morpheus.json` for LLVM target configuration.
