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

/**
|
||||
* This file defines the Secure Monitor Call (SMC) message protocol used for
|
||||
* service layer driver in normal world (EL1) to communicate with secure
|
||||
* monitor software in Secure Monitor Exception Level 3 (EL3).
|
||||
*
|
||||
* This file is shared with secure firmware (FW) which is out of kernel tree.
|
||||
*
|
||||
* An ARM SMC instruction takes a function identifier and up to 6 64-bit
|
||||
* register values as arguments, and can return up to 4 64-bit register
|
||||
* value. The operation of the secure monitor is determined by the parameter
|
||||
* values passed in through registers.
|
||||
*
|
||||
* EL1 and EL3 communicates pointer as physical address rather than the
|
||||
* virtual address.
|
||||
*
|
||||
* Functions specified by ARM SMC Calling convention:
|
||||
*
|
||||
* FAST call executes atomic operations, returns when the requested operation
|
||||
* has completed.
|
||||
* STD call starts a operation which can be preempted by a non-secure
|
||||
* interrupt. The call can return before the requested operation has
|
||||
* completed.
|
||||
*
|
||||
* a0..a7 is used as register names in the descriptions below, on arm32
|
||||
* that translates to r0..r7 and on arm64 to w0..w7.
