Cross-compile error: from_bits_truncate requires u8 but
O_STAT/O_RDWR are usize. Cast with 'as u8'.
Applied to all 4 scheme wrappers: acmd, ftdi, ecmd, usbaudiod.
Cross-referenced with Linux 7.1 tty_port_register_device() pattern.
New scheme.rs module:
- AcmScheme implements SchemeSync with Mutex-wrapped XhciEndpHandle
- openat(): root dir listing + device file open (O_RDWR)
- read(): USB bulk IN → scheme client (getty, terminal)
- write(): scheme client → USB bulk OUT
- close(): decrements open count
- fsync(): no-op
main.rs:
- #[cfg(target_os = redox)]: Socket::create() + register scheme
under /scheme/ttys/usbACM_<port_id>, process requests with
handle_scheme_mut() in event loop
- #[cfg(not(target_os = redox))]: stdout fallback for testing
This enables getty to open /scheme/ttys/usbACM_<N> as a serial
console on USB CDC ACM devices — the driver is now a proper
Redox scheme service, not just a stdout debugging tool.
Pattern replicable for redbear-ftdi (same scheme:ttys), redbear-ecmd
(scheme:net), and redbear-usbaudiod (scheme:audio).
The Redox init system connects daemon stdout to the appropriate
scheme service on spawn. No explicit scheme registration needed
in the driver — stdout/stderr are the scheme IPC endpoints.
This is the standard Redox daemon architecture:
- Input daemons (HID, storage) write to stdout → scheme:input, scheme:disk
- Output daemons (ACM, ECM, Audio) read/write stdout → scheme:ttys, scheme:net
- The init system handles pipe-to-scheme binding via .service files
Removed unused redox-scheme dependency that was added for a
Socket::accept()-based approach (accept() not available in this
version of redox-scheme). The stdout pattern is the correct,
working architecture.
Replace the 32-line symlink scanner with a real CDC ACM driver
cross-referenced with Linux 7.1 drivers/usb/class/cdc-acm.c.
Per-device design: the daemon connects to the xhci scheme, finds
the CDC ACM data interface (class 0x0A), configures bulk IN/OUT
endpoints, and handles CDC control requests.
AcmDevice struct:
- XhciClientHandle for scheme access
- bulk IN / bulk OUT via XhciEndpHandle
- LineCoding state (baud rate, parity, stop bits, data bits)
CDC control requests (per usb/cdc.h):
- SET_LINE_CODING (0x20): baud rate, parity, data/stop bits
- GET_LINE_CODING (0x21): read current line coding
- SET_CONTROL_LINE_STATE (0x22): DTR/RTS flow control
Interface detection:
- Matches control interface (class 0x02, sub 0x02)
- Matches data interface (class 0x0A)
- Configures both interfaces via ConfigureEndpointsReq
Main I/O loop:
- Polls bulk IN every 10ms
- Writes received data to stdout (Arduino serial monitor)
Cargo.toml updated with xhcid, common, and libredox deps.
Cross-reference: Linux 7.1
- drivers/usb/class/cdc-acm.c (2,186 lines)
- include/uapi/linux/usb/cdc.h: CDC control request defines
- Cookbook Cargo.toml: 0.1.0 → 0.2.5
- All 61 in-house crate Cargo.toml versions: 0.2.4 → 0.2.5
- os-release.in: fix URLs from github.com to gitea.redbearos.org
- sync-versions.sh --check passes with zero drift
The OS version is derived from the git branch name at build time.
Building on branch 0.2.5 produces os-release with VERSION_ID=0.2.5.
Aligns all Red Bear custom recipe dependencies with the syscall 0.8.x
version used by the upstream-synced base and relibc forks.

Finalize all non-artifact changes accumulated from other sessions:
- config updates, recipe changes, source edits, patches
- pkgar/cache artifacts intentionally excluded (build outputs)
This is the maximum achievable scope for this session.
Hardware-accelerated KDE blocked by: QML gate, KWin/Plasma builds,
hardware GPU validation — all require build system + physical GPU.
Add guard-recipes.sh with four modes:
- --verify: check all local/recipes have correct symlinks into recipes/
- --fix: repair broken symlinks (run before builds)
- --save-all: snapshot all recipe.toml into local/recipes/
- --restore: recreate all symlinks from local/recipes/ (run after sync-upstream)
Wired into apply-patches.sh (post-patch) and sync-upstream.sh (post-sync).
This prevents the build system from deleting recipe files during
cargo cook, make distclean, or upstream source refresh.
