- * kprintf.cc — Kernel formatted output
- *
- * Uses mpaland/printf's vsnprintf_ as the core formatting engine.
- *
- * Architecture:
- *   vsnprintf_()  ← pure formatting, writes to buffer
- *       ↓
- *   kprintf()     ← format + emit via console_write_all()
- *   kvprintf()    ← va_list variant
- *   ksnprintf()   ← format into caller's buffer
- *
- * Output path:
- *   Pre-registration:  console_write_all() → early_putc() fallback
- *   Post-registration: console_write_all() → struct console chain
