restore lost packages from 0.2.3 + fix overwritten 0.2.4 files
- Restore 29 recipe symlinks (libdrm, qtbase, dbus, sddm, pipewire, etc.) - Restore 33 patches (KDE, libdrm, mesa, pipewire, sddm, wireplumber) - Restore 20+ local/scripts (audit, lint, test, build helpers) - Restore src/cook/scheduler.rs, status.rs, gnu-config/ - Restore scripts/patch-inclusion-gate.sh, run_mini1.sh, validate-collision-log.sh - Recover TLC source from HEAD (was overwritten by 0.2.3 checkout) - Recover 11 local/docs plans from HEAD (were overwritten) - Recover qt6-wayland-smoke symlink from HEAD - Fix MOTD: remove garbled ASCII art, use clean text - Update version: 0.2.0 -> 0.2.4 in os-release, motd, config - Reduce filesystem_size: 1536 -> 512 MiB - Add ABSOLUTE RULE to AGENTS.md: never delete/ignore packages - Reduce pcid scheme log verbosity: info -> debug

/**
|
||||
* DOC: Generic Radix Page Table
|
||||
*
|
||||
* Generic Radix Page Table is a set of functions and helpers to efficiently
|
||||
* parse radix style page tables typically seen in HW implementations. The
|
||||
* interface is built to deliver similar code generation as the mm's pte/pmd/etc
|
||||
* system by fully inlining the exact code required to handle each table level.
|
||||
*
|
||||
* Like the mm subsystem each format contributes its parsing implementation
|
||||
* under common names and the common code implements the required algorithms.
|
||||
*
|
||||
* The system is divided into three logical levels:
|
||||
*
|
||||
* - The page table format and its manipulation functions
|
||||
* - Generic helpers to give a consistent API regardless of underlying format
|
||||
* - An algorithm implementation (e.g. IOMMU/DRM/KVM/MM)
|
||||
*
|
||||
* Multiple implementations are supported. The intention is to have the generic
|
||||
* format code be re-usable for whatever specialized implementation is required.
|
||||
* The generic code is solely about the format of the radix tree; it does not
|
||||
* include memory allocation or higher level decisions that are left for the
|
||||
* implementation.
|
||||
*
|
||||
* The generic framework supports a superset of functions across many HW
|
||||
* implementations:
|
||||
*
|
||||
* - Entries comprised of contiguous blocks of IO PTEs for larger page sizes
|
||||
* - Multi-level tables, up to 6 levels. Runtime selected top level
|
||||
* - Runtime variable table level size (ARM's concatenated tables)
|
||||
* - Expandable top level allowing dynamic sizing of table levels
|
||||
* - Optional leaf entries at any level
|
||||
* - 32-bit/64-bit virtual and output addresses, using every address bit
|
||||
* - Dirty tracking
|
||||
* - Sign extended addressing
