ACPI-FIXES.md: Add MADT entry types table (0x0-0xA), update all tables to reflect 17 kernel fixes and 9 userspace fixes, mark crash reports resolved, add compile-time assertions note. Document FADT full parse, power methods, shutdown/reboot.
AGENTS.md: Mark ACPI as Complete in Bare Metal Boot Status table with 4 new rows (shutdown, reboot, power). Strike through P0 in Phased Roadmap. Update Critical Path to show P0 DONE.

Rebuild base/acpid patch as comprehensive unified diff combining: DMAR iterator fix, FADT shutdown via PM1a/PM1b CNT_BLK with S5 sleep types from _S5 AML, ACPI reset register reboot with keyboard controller fallback (port 0x64, 0xFE), and power methods (_PS0/_PS3/_PPC). GenericAddress now supports memory-mapped and I/O port writes. Reboot wired into main.rs event loop with reboot_requested flag. All ivrs/mcfg stub references removed. Validated with git apply --check against upstream base source.

Add MadtLocalApicNmi (type 0x4), MadtLapicAddressOverride (type 0x5), and MadtLocalX2ApicNmi (type 0xA) structs with compile-time size assertions. Add enum variants and iterator cases for all three. Implement set_lvt_nmi() on LocalApic for both xAPIC (LINT0/LINT1 at offsets 0x350/0x360) and x2APIC (MSRs 0x835/0x836) with NMI delivery mode, polarity, and trigger mode from MADT flags. Process NMI entries in x86.rs MADT loop to configure per-CPU LVT NMI registers. Parse and log LAPIC address override (64-bit) for future use.

Add Sdt::validate_checksum() method that sums all bytes in the table and verifies the result is zero per ACPI spec. Call it during ACPI table iteration in init() — warn on invalid checksum but do not skip the table, to avoid breaking boot on firmware with slightly incorrect checksums.

The base patch referenced ivrs and mcfg modules that don't exist in the source tree, causing build failures. Removed the module declarations, imports, and init calls. MCFG is already handled by pcid (the PCI daemon). IVRS (AMD IOMMU) needs real implementation, not a stub. DMAR iterator fix and Dmar::init() call preserved.

The critical fix: local_apic.rs id() now returns (read(0x20) >> 24) for xAPIC mode instead of the raw register value. This was causing wrong APIC IDs on Intel, leading to misrouted IPIs, missed TLB shootdowns, and the page fault during context switch at switch.rs:317.
Also adds:
- Named ICR constants (ICR_INIT_ASSERT, ICR_STARTUP) with bit-layout comments
- Comment documenting x2APIC timeout limitation (cpu_id allocated before timeout check)
- All existing changes preserved (x2APIC MADT type 9, cpuid split, memory alignment, RSDP checksum, ICR pending wait, MADT entry length guard)

Downloads source for every package in a given config (or all configs). Supports --recipe NAME for single package, --list to show packages, and --status to check fetch state. Builds repo binary automatically if needed.

integrate-redbear.sh is an idempotent overlay setup script: creates symlinks for custom recipes, patches, and configs; stages branding assets and firmware into local recipe sources; writes a tag file for the build system. mk/redbear.mk wires it as a make target with Podman support.

Add mc recipe (v4.8.30) with Redox-specific patch disabling PTY, resolver, subshell, and SFTP/FTP VFS. Build with ncurses against glib. Symlink into recipes/tui/. Add mc package to redbear-desktop, redbear-full, and redbear-minimal configs.

Commit Red Bear OS icon and loading background images to the branding recipe source. Update .gitignore to exclude fetched tarballs, build artifacts, and target/ dirs inside local/recipes/ while preserving tracked source code.

Replace all 'rbos'/'RBOS' references with 'redbear'/'Red Bear OS'
across the build system, scripts, docs, and configs. Renamed files:
rbos.ipxe → redbear.ipxe
assets/rbos-icon.png → assets/redbear-icon.png
recipes/system/rbos-info → recipes/system/redbear-info
Added redbear-info: a system tool that enumerates all Red Bear OS
custom components, checks runtime availability via scheme paths and
binary presence, and prints status/test info. Supports --verbose,
--json, and --test output modes. Zero external dependencies.
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)
Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.
Build: make all CONFIG_NAME=redbear-full
Sync: ./local/scripts/sync-upstream.sh
