Module kprint 

Kernel print macro ([kprint!]) and the logging state behind it.

Authors: MarioS271

Structs

KernelPrintState 🔒

All mutable state for the kprint subsystem, protected by an IrqMutex.

KernelWriter

RAII handle that holds the KPRINT_STATE lock for one kprint! call, preventing interleaved output.

Enums

LogLevelColor

Constants

LOG_BUFFER_SIZE 🔒

Capacity of the in-memory log ring buffer in bytes.

Statics

KPRINT_STATE 🔒

Global logging state. Wrapped in IrqMutex so interrupt handlers can log safely.

Functions

force_unlock_kprint_state^⚠

Release KPRINT_STATE’s lock without restoring the interrupt flag, for panic paths.

kprint 🔒

Write string to the ring buffer, serial port, and framebuffer (if each is initialized).

write_log_buf 🔒

Append s to the ring buffer, advancing the tail when the head laps it.
