Tick counter interface for profiling. More...

Detailed Description

Tick counter interface for profiling.

Includes the platform-specific timing backend (generated by sloth from the MCU manifest's timing capability) and provides the TickScope RAII helper. The generated backend supplies:

• sbl::hw::timing::init() — call once at startup
• sbl::hw::timing::read() — free-running counter (wraps at 2^32)
• sbl::hw::timing::rate() — ticks per second

Platform implementations (selected by MCU manifest):

• dwt: ARM DWT CYCCNT (hardware cycles)
• posix_monotonic: clock_gettime CLOCK_MONOTONIC (nanoseconds)
• sdk_timer: Pico SDK hardware timer (microseconds)
