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

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.

[dfs] Mark dirty on unmap on shared mapping only (#9195)

2024-07-16T09:03:54Z

[dfs] feat: Mark dirty on unmap for shared mapping This patch optimizes the pcache varea management by refining the conditions under which pages are marked dirty, specifically targeting the unmap operations in the dfs_pcache component. These changes were necessary to enhance the efficiency of page cache management. Changes: - Adjusted include statements in `dfs_pcache.c` for better organization. - Modified `dfs_aspace_unmap` function: - Added a check to ensure `varea` is not privately locked before marking a page as dirty. - Updated `dfs_aspace_page_unmap` function: - Added a similar check for `varea` lock status before marking a page as dirty.
