feat: mm: added affinity pages allocator

2025-02-25T03:26:30Z

This patch introduces a tagged pages allocator to address the existing problems of page aliasing on specific platforms and the requirement of page coloring. It implements an affinity-id aware page manager by separating the runtime page list into two types: a normal single linked-list and a multi-dimensional affinity-list. Changes: - Introduced tagged pages allocator and managing algorithm for affinity pages list - Modified components to support affinity-id list management - Updated page allocation and freeing functions to handle tagged pages - Added configuration options for page affinity block size and debugging - Modified mmap and elf loading to respect affinity settings - Enhanced page list management to support multi-dimensional affinity-list Signed-off-by: Shell

doxygen: add prefix for groups (#9991)

feat: add support for dfs remount functionality

2025-01-06T11:34:16Z

This patch introduces a remount feature for the DFS, allowing for the modification of mount parameters without unmounting the filesystem, the remount functionality helps modify certain mount flags (like `MS_RDONLY`) without requiring an unmount, providing more control over mounted filesystems in the system. The updates is essential for user space init proc to cleanup the runtime resource, ensuring clean handling of cached data and enhancing system robustness during power down processing. Changes: - Defined new constants for remount flags in `dfs_fs.h`. - Added the `dfs_remount()` function in `dfs_fs.c` to handle remount operations. - Introduced a check for unsupported flags and handle error conditions such as invalid paths or non-directory targets. - Updated the `dfs_mnt` structure in `dfs_mnt.h` to include a read-only flag (`MNT_RDONLY`). - The `dfs_remount()` function allows changing the read-only status of a mounted filesystem. - Added `MNT_LAZY_UMNT` and `MNT_RDONLY` flags to `dfs_mnt` structure. - Introduced `dfs_mnt_setflags` function for dynamic flag management. - Updated `dfs_remount` to utilize `dfs_mnt_setflags` for flag setting. - Enhanced unmount operations with `dfs_mnt_umount_iter` and lazy unmounting. - Added `dfs_pcache_clean` to handle cache cleanup for read-only mounts. - Improved error reporting in `dfs_umount` for better user feedback. - Refactored `sys_mount` to streamline parameter handling and support remounts. - Introduced `_cp_from_usr_string` helper for user-space string operations. - Updated internal APIs to ensure consistency in reference count management.

feat: add system reboot and process teardown support

2025-01-06T11:34:16Z

The patch introduces support for system reboot functionality and process teardown, allowing for a clean shutdown and unmounting of the root filesystem. This is necessary for ensuring a proper system shutdown process, especially when dealing with resource cleanup and ensuring that all processes have exited before system shutdown. Changes: - Added `lwp_teardown()` function to handle process cleanup and system teardown. - Introduced `lwp_pid_wait_for_empty()` to wait for process ID table emptiness before proceeding with shutdown. - Updated `dfs_mnt_unref()` to trigger callbacks when unmounting a filesystem. - Added new reboot types (`RB_AUTOBOOT`, `RB_POWER_OFF`) and implemented their corresponding actions, including cleanup of processes and unmounting root filesystem. - Extended `sys_reboot()` to handle reboot and power off types with appropriate callbacks for process and filesystem teardown. - Introduced callback mechanism for root filesystem unmount notifications.
