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

[smart] feat: add unmap for null mapper (#9186)

2024-07-16T12:38:55Z

Do unmap before shrink so we don't see mapped entry on page table insertion, which is not acceptable for riscv implementation of architecture porting. Changes: - add un-mapping of pte on `_null_shrink()` Signed-off-by: Shell

[smart] fixup of script execution (#9009)

2024-05-31T09:32:19Z

This patch fixup the script execution capabilities on argv passing and adds support for arguments larger than 4k. According to POSIX, the script parameter is quiet different from the current implementation. Especially on the way it inserts the path of executables. At the end, when you execute a script from `$PATH`, it always fails. For the script, interpreter will be invoked with the following arguments: `{interpreter [optional-arg] pathname arg...}` where pathname is the pathname of the file specified as the first argument of execve(), and arg... is the series of words pointed to by the argv argument of execve(), starting at argv[1]. Note that there is no way to get the argv[0] that was passed to the execve() call. The changes include: - Separating argument, environment variable, and auxiliary vector processing into a new lwp_args.c file. - Fixing bugs in script argument processing and supporting arguments larger than 4k. - Updating lwp_execve to use the new argscopy function and removing the old lwp_argscopy function. - Making various modifications to lwp_load and elf_aux_fill to work with the new argument processing. - Removing unnecessary code related to dynamic loading and interpreter scripts.
