  • Increased the maximum number of blocked GPU inodes supported.
  • Expanded usage guidance for GPU selection, mode switching, application launching, Smart Mode, diagnostics, and power-state checks.

• Documentation

  • Added comprehensive D-Bus interface references, including configuration, GPU, mode, policy, logging, debugging, and management APIs.
  • Updated installation, build, BPF, troubleshooting, and runtime requirements.
  • Clarified GPU routing, MUX behavior, service recovery, and multi-GPU environment settings.
  • Improved development documentation navigation and removed outdated guidance.

Walkthrough

The scrolls update eBPF and Smart Mode documentation, reorganize D-Bus references, expand build and usage instructions, correct diagnostics, and raise CW_BLOCKED_INO capacity to 16,384 entries.

Changes

eBPF and Smart Mode

Layer / File(s)	Summary
eBPF and Smart Mode behavior crates/cardwire-ebpf/src/maps.rs, docs/development/bpf.md, docs/development/smart.md, docs/introduction.md	The documentation now describes current eBPF maps, PID cleanup, inode-blocking rules, Smart Mode policies, and userspace analysis. CW_BLOCKED_INO capacity increases to 16,384 entries.

D-Bus interface reference

Layer / File(s)	Summary
D-Bus interface reference docs/SUMMARY.md, docs/development/dbus.md, docs/development/dbus/*, docs/development/smart.md	The D-Bus overview now links to separate Manager, Mode, Config, GPU, Logger, SmartPolicy, Debug, and Switcheroo Control pages. The pages document their methods, properties, signals, paths, and behavior.

Build and usage guidance

Layer / File(s)	Summary
Build and usage guidance docs/development/build-dev.md, docs/getting-started/installation.md, docs/getting-started/requirements.md, docs/getting-started/usage.md	The documentation adds current CI checks, build dependencies, toolchain requirements, BPF LSM verification, GPU commands, application launching, and daemon status operations.

Diagnostic guidance

Layer / File(s)	Summary
Diagnostic guidance docs/diagnostics/*, docs/introduction.md	The diagnostic guidance corrects MUX behavior, reboot requirements, service restart behavior, and related wording.

Estimated code review effort: 3 (Moderate) | ~20 minutes
