ra8_ftl_pblock_t Struct Reference

Caller-owned metadata for one physical erase block. More...

#include <ra8_ftl.h>

Data Fields
uint32_t	erase_count
	Cumulative erases of this block (wear metric).
uint8_t	state
	ra8_ftl_pstate_t lifecycle state (private).

Detailed Description

Caller-owned metadata for one physical erase block.

One entry per physical block of the underlying device. Zero-initialise the whole array (= {}): all-zero means every block is FREE with a zero erase count, which is the correct cold-start state. Treat the fields as private; the FTL maintains them.

Invariant

state is one of ra8_ftl_pstate_t.

erase_count is monotonically non-decreasing across the device lifetime.
